I'm trying to generate an MDEntryTime with a value that contains milliseconds. The milliseconds are getting dropped once they get entered into the Message. Upon further inspection, I find this little gem inside Field.h
explicit UtcTimeOnlyField( int field, const UtcTimeOnly& data, bool showMilliseconds = false )
The constructor for MDEntryTime doesn't allow for the coder to set showMilliseconds=true. How do people get around this?
The constructor for MDEntryTime doesn't allow for the coder to set showMilliseconds=true.
In fact, it does. The following should work for you:
msg.set(FIX::MDEntryTime(FIX::UtcTimeOnly(time(NULL), true)));
This one works for me. I did a method that ensure milliseconds are present in the UtcTimeOnly:
FIX::UtcTimeOnly getTimeMillis()
{
timeval tv;
gettimeofday(&tv, NULL);
return FIX::UtcTimeOnly(tv.tv_sec, tv.tv_usec / 1000);
}
And then, I set the field this way:
msg.setField(FIX::UtcTimeOnlyField(FIX::FIELD::MDEntryTime, getTimeMillis(), true));

I have tried to contact the original designer for the ADS1115->EmonLib adaptation, but unfortunately his Github page has no contact information. I have also tried asking on the OpenEnergyMonitor forum and I get "Contact the person who made the changes".
So, I've come here in the hopes that the knowledgeable folk here can help me out.
Situation:
I have an ESP32 that I'm going to be using to monitor my energy consumption of my home. Because I will be monitoring several circuits I need lots of sensors. The ESP32 only has a 12-bit ADC and I'm limited to only a few sensors. Also limits future expansion if needed.
So here comes the ADS1115, which is a 16-bit ADC, but it uses I2C. Unfortunately, the EmonLib was designed to use onboard ADC, and not through an I2C device. So after doing some digging around, I found this modification to allow the ADS1115 to be used:
https://github.com/PaulWieland/EmonLib/
However, Paul Wieland is not able to be contacted through github.
Ok, so if I wanted to use only 1 ADS1115, I could just use his code as stock, which is this:
// In this example we will use an ADS1115 breakout board instead of the Arduino's local analog inputs
// This is especially useful for nodemcu/esp8266 users who only have a single analog input
#include <Wire.h>
#include <Adafruit_ADS1015.h>
// EmonLibrary examples openenergymonitor.org, Licence GNU GPL V3
#include <EmonLib_I2C.h> // Include Emon Library
EnergyMonitor emon1; // Create an instance
Adafruit_ADS1115 ads; // Create an instance of the ADS1115 object
// Make a callback method for reading the pin value from the ADS instance
int ads1115PinReader(int _pin){
return ads.readADC_SingleEnded(_pin);
}
void setup()
{
emon1.inputPinReader = ads1115PinReader; // Replace the default pin reader with the customized ads pin reader
emon1.current(1, 111.1); // Current: input pin, calibration.
}
void loop()
{
double Irms = emon1.calcIrms(1480); // Calculate Irms only
Serial.print(Irms*230.0); // Apparent power
Serial.print(" ");
Serial.println(Irms); // Irms
}
This compiles just fine. Though I am kinda confused as to how to select the "pin" of the ADS.
In the emonlib.cpp he added this code:
//--------------------------------------------------------------------------------------
// Constructor. Set the pinReader to the default pin reader method
//--------------------------------------------------------------------------------------
EnergyMonitor::EnergyMonitor()
{
this->inputPinReader = defaultInputPinReader;
}
//--------------------------------------------------------------------------------------
// By default we just call Arduino's analogRead
//--------------------------------------------------------------------------------------
int EnergyMonitor::defaultInputPinReader(int _pin)
{
return analogRead(_pin);
}
And changed this:
startV = analogRead(inPinV);
to:
startV = (this->inputPinReader)(inPinV);
and a few other spots where he made the adjustment using "this->".
And in the emonlib.h he added this to the Public section:
EnergyMonitor();
typedef int (*inputPinReaderMethod) (int _pin);
inputPinReaderMethod inputPinReader;
static int defaultInputPinReader(int _pin);
Now, for a single ADS1115, I think this works. At least the code compiles. But I need to use 4 ADS1115's as I'll need to be able to monitor up to 16 circuits. I can't for the life of me figure out how to add an array of ADS's to an array of emonlib's.
I tried doing this:
EnergyMonitor emon1[4]; // Create an instance
Adafruit_ADS1115 ads[4]; // Create an instance of the ADS1115 object
// Make a callback method for reading the pin value from the ADS instance
int ads1115PinReader(int _channel, int _pin){
return ads[1].readADC_SingleEnded(_pin);
}
void setup()
{
emon1[1].inputPinReader = ads1115PinReader; // Replace the default pin reader with the customized ads pin reader
emon1[1].current(1, 111.1); // Current: input pin, calibration.
}
void loop()
{
double Irms = emon1[1].calcIrms(1480); // Calculate Irms only
Serial.print(Irms*230.0); // Apparent power
Serial.print(" ");
Serial.println(Irms); // Irms
}
but then I get this error:
Emon_ADS_Test:18:27: error: invalid conversion from 'int (*)(int, int)' to 'EnergyMonitor::inputPinReaderMethod {aka int (*)(int)}' [-fpermissive]
emon1[1].inputPinReader = ads1115PinReader; // Replace the default pin reader with the customized ads pin reader
I'm not very advanced in coding, and function pointers just confuse the heck outta me.
So my dilemma is I have several ADS1115's I need to match to the several instances of the EmonLib.
There has to be a separate instance for each wire monitored. On my working model that uses an Arduino Nano I have 2 emonlib variables (emon1, emon2). This works fine as it uses the internal ADC, tho I've found out over time that it is not very accurate and not fast enough or high enough resolution for my needs. (ie. when 0-current is flowing, it shows 50W usage).
What do I need to make a change to make this thing work?

[UPDATE 1]
Ok, after some testing, I do still get this:
emon[i * j].inputPinReader = ads1115PinReader;
emon[i * j].current(j++, 111.1);
Unfortunately this throws an error still:
Emon_ADS_Test:21:33: error: invalid conversion from 'int (*)(int, int)' to 'EnergyMonitor::inputPinReaderMethod {aka int (*)(int)}' [-fpermissive]
emon1[i * j].inputPinReader = ads1115PinReader;
However, it comes to the function pointer as being a problem.
I use this code:
int ads1115PinReader(int _pin){
return ads.readADC_SingleEnded(_pin);
}
It works just fine. However if I do this:
int ads1115PinReader(int _channel, int _pin){
return ads[_channel].readADC_SingleEnded(_pin);
}
I get the error above. In the EmonLib_I2C library, the only thing I can think of is in this part:
typedef int (*inputPinReaderMethod) (int _pin);
inputPinReaderMethod inputPinReader;
static int defaultInputPinReader(int _pin);
not matching up. But even that doesn't make sense. In this line:
emon.inputPinReader = ads1115PinReader; // Replace the default pin reader with the customized ads pin reader
does that mean that when I call inputPinReader, it "actually" grabs the value from ads1115PinReader instead of the one in the library?
I am writing a protractor test case to compare the name(s) of the displayed data is same as the searched name.
Even though my test case works fine, I am not able to understand what is happening. Because when i expect the name to compare, it compares as expected, but when i print the elementFinder's(rowData)(i have attached the output screen shot here) value in console.log, it show a huge list of some values which i am not able to understand?
PS: I am a newbie to protractor`
This is the testCase:
it('should show proper data for given last name', function () {
var searchValue='manning';
searchBox.sendKeys(searchValue);
search.click();
element.all(by.binding('row.loanNumber')).count().then(function(value) {
var loanCount = value;
for (var i = 0; i < loanCount; i++) {
var rowData = element.all(by.binding('row.borrowerName')).get(i).getText();
expect(rowData).toMatch(searchValue.toUpperCase());
console.log(rowData,'*****',searchValue.toUpperCase());
}
});
});`
And give me valuable suggestions about my style of code
rowData is a promise (not a value), so when you console.log it, you get the promise object
Protractor patches Jasmine to automatically resolve promises within the expect(), so that's how it knows to resolve the value and compare to the expected result.
If you want to console.log the value, you need to resolve the promise with .then() to get the value.
rowData.then(function(rowDataText) {
console.log(rowDataText);
)}
This is pretty much everyone's first question when they start using protractor. You will want to learn how promises work if you want a good understanding of how to manipulate them.
I've noticed that if a date property comes back from the server with the value "2013-07-11T17:11:04.700", then breeze changes the value to Thu Jul 11 19:11:04 UTC+0200 2013.
Notice the time is now 2 hours ahead !
I had already come across this issue when saving entities, so I had to explicitly convert my date properties using momentjs :
date.hours(date.hours() - moment().zone() / 60);
But now it seems the problem occurs also when doing read operations.
What's the best way to make sure breeze does not alter values of my date properties ?
Breeze does not manipulate the datetimes going to and from the server in any way EXCEPT to add a UTZ timezone specifier to any dates returned from the server that do not already have one. This is only done because different browsers interpret dates without a timezone specifier differently and we want consistency between browsers.
The source of your issues is likely to be that when you save your data with dates to the database, that the dateTime datatype you are using does NOT contain a timezone offset. This means that when the data is retrieved you are likely "losing" the offset and the Breeze default mentioned above kicks in. This can be corrected by using a database date time datatype with an timezone offset ( datetime2 or datetimeoffset in SQLServer).
Note that your browser DOES format dates according to it's current timezone.
Another approach is that you can replace Breeze's DataType.parseDateFromServer to NOT infer any time zone info if it is not provided:
breeze.DataType.parseDateFromServer = function (source) {
return new Date(Date.parse(source));
};
However, this can run into the problem that different browsers interpret DateTime strings without a time zone offset differently... So you may still get strange results depending on the browser. If that happens you will need to add some browser detection code to the snippet above.
Another alternative is to do the following using the moment.js library.
breeze.DataType.parseDateFromServer = function (source) {
var date = moment(source);
return date.toDate();
};
Not sure how helpful this is, but hopefully Breeze's behavior is clearer.
By default, Breeze does not provide any way to do this, but you can keep the below code in your model JS file to overcome this issue:
breeze.DataType.parseDateFromServer = function (source) {
if (typeof source === 'string') {
//Check for local offset time or UTC time from server
if (source.slice(-1) !== "Z") {
var oldSource = source;
try {
source = source.substring(0, source.lastIndexOf("-") - 1)
source = new Date(source);
var tzDifference = source.getTimezoneOffset();
//convert the offset to milliseconds, add to targetTime, and make a new Date
var offsetTime = new Date(source.getTime() + tzDifference * 60 * 1000);
return offsetTime;
}
catch (err) {
source = new Date(source);
return source;
}
}
else {
source = new Date(source);
var tzDifference = source.getTimezoneOffset();
//convert the offset to milliseconds, add to targetTime, and make a new Date
var offsetTime = new Date(source.getTime() + tzDifference * 60 * 1000);
return offsetTime;
}
}
}
i am creating a basic GROUND CONTROL STATION for a CubeSat, dividing it in two parts: COMMANDS (with no problems) and TELEMETRY. I am using C code and GTK; in the telemetry windowt I need to show some info everytime a telemetry packet is received so I've tried to use a gtkview/gtkentry for each info, but I don't know, how to update the message shown in them.
In particular, an example is:
//View PACKET NUMBER
view = gtk_text_view_new();
frame = gtk_frame_new("Packet number");
gtk_container_add(GTK_CONTAINER(frame), view);
gtk_text_view_set_editable(GTK_TEXT_VIEW(view),FALSE);
gtk_table_attach(GTK_TABLE(table2),frame,0,1,0,1,GTK_FILL,GTK_FILL,5,5);
buff = gtk_text_view_get_buffer(GTK_TEXT_VIEW(view));
gtk_text_buffer_get_iter_at_offset(buff, &iter, 0);
gtk_text_buffer_insert(buff, &iter,"waiting", -1);
so, first there is the text "WAITING", then when a packet is received I want to update that text: how can I do this?
I've tried repeating this code but changing "waiting" with a variable referring to "packet number", but I obtain core dump
I've also tried with this code, but I have always same problem.
viewprova = gtk_entry_new();
frameprova = gtk_frame_new("Packet number");
gtk_container_add(GTK_CONTAINER(frameprova), viewprova);
gtk_entry_set_editable(GTK_ENTRY(viewprova),FALSE);
gtk_table_attach(GTK_TABLE(table2),frameprova,0,1,0,1,GTK_FILL,GTK_FILL,5,5);
gtk_entry_set_text(GTK_ENTRY(viewprova),"waiting");
frameprova = gtk_frame_new("Packet number");
viewprova = gtk_label_new ("waiting");
gtk_container_add(GTK_CONTAINER(frameprova), viewprova);
gtk_table_attach(GTK_TABLE(table2),frameprova,0,1,0,1,GTK_FILL,GTK_FILL,5,5);
Thanks for the help!
A function such as gtk_label_new() that accepts a C string can't take an integer instead, C functions are not polymorphic. You need to build a string representation and pass that, for instance using snprintf() to format the number into a string buffer.
Ok, so if I understood you correctly, you know how to setup your text displaying widgets, but not, how to fill them with new contents, correct? Look at your code, and at what you're doing. First, you're creating a text widget. Then you fill it with initial text. This second part is the one you repeat:
In case of GtkEntry, gtk_entry_set_text(GTK_ENTRY(viewprova), "My new text");
In case of GtkTextView (actually you're using the underlying TextBuffer), gtk_text_buffer_set_text(buff, "My new text", -1);
I've got this odd problem.
If I make a call on that function through amfphp service browser and give it a valid ID and leave the $num_images field blank amfphp will actually pass a blank string as the argument.
// if i call this function width just an ID
function getWorkers($id, $num_images = 100) {
...
// num_images will be set as ''
}
I can easily override using a check:
function getWorkers($id, $num_images = 100) {
if($num_images=='') $num_images = 100;
...
// num_images will now be really set as 100
}
Anyone experiencing the same with amfphp?
That's odd, I never got that from AMFPHP. If you don't have the latest version try updating your installation of AMFPHP. Also make sure Flash doesn't somehow pass an empty variable as the second variable.
