Please, help to solve the problem with communication establishment between PC and 1211C (6ES7-211-1BD30-0XB0 Firmware: V 2.0.2). I feel that I've made a stupid mistake somewhere, but can't figure out where exactly it is.
So, I'm using function TRCV_С...
The configuration seems to be okay:
When i set the CONT=1, the connection establishes without any problems...
But, when i set EN_R=1, I'm getting "error 893A".
That's what I have in my diagnostic buffer: (DB9 - is a block where the received data is supposed to be written)
There is an explanation given for "893A" in the manuals: Parameter contains the number of a DB that is not loaded. In diag. buffer its also written that DB9 is not loaded. But in my case it is loaded! So what should I do in this case?
it seems that DB were created or edited manually due to which they are miss aligned with FB instances try removing and DB and FB instances and then add again instances of FBs with automatically created DBs and do a offline dowonload

[ script:es_extended] SCRIPT ERROR: #es_extended/server/functions.lua:127: attempt to index a nil value (local 'xPlayer')
[ script:es_extended] > ref (#es_extended/server/functions.lua:127)
Please help me im triggered af Thats my Fivem Console (TxAdmin) Nothing works Esx is completly broke after a server Restart
I had a look at the source code. My best guess is that the player you are using isn't registered in the MySQL database for some reason.
I am guessing this because of the following:
The immediate cause of the error is that xPlayer is nil in server/functions.lua:127
This is due to the player object not being added to the ESX.Players table in server/main.lua:239
The info necessary to make the player object is taken from MySQL on server/main.lua:115
So the most obvious explanation would be that the user wasn't found in the database. It is also possible that the program could not connect to the database at all, but it looks like the fivem-mysql-async library would raise an error instead of continuing silently, so that is less likely (although this would need testing to discount completely).
Are there any messages in the server logs that might give you a clue as to what's going on?
I'm trying to filter a signal and then analyse the values of the filtered signal using Tone.js / Web-Audio API.
I'm expecting to get values of the filtered signal, but I only get -Infinity, meaning that my connections between the nodes are wrong. I've made a small fiddle demonstrating this, however in my use-case I do not want to send this node to the destination of the context - I only want to analyse it, not hear it.
osc.connect(filter)
filter.connect(gainNode)
gainNode.connect(meter)
console.log(meter.getLevel())
I guess you tested the code in Chrome because there is a problem with Chrome which causes it to not process anything until it is connected to the destination. When using Tone.js that means you need to call .toMaster() at the end of your chain. I updated you fiddle to make it work: https://jsfiddle.net/8f7abzoL/.
In Firefox calling .toMaster() is not necessary therefore the following works in Firefox as well: https://jsfiddle.net/yrjgfdtz/.
After some digging I've found out that I need to have a scriptProcessorNode - which is apparently no longer recommended - so looking into Audio Worklet Nodes
I am trying to make a patch that plays audio when a bang is pressed. I have put a symbol so that I don't need to keep reimporting the file. However it works sometimes but not all the time.
A warning in the Pd console reads: Start requested with no prior open
However I have imported an audio file
Is there something that I have done wrong?
Use [trigger] to get the order-of-execution correct.
One problem is, that whenever you send a [1( to [readsf~] you must have sent an [open ...( message directly beforehand.
Even if you have just successfully opened a file, but then stopped it (with [0() or played it through (so it has been closed automatically), you have to send the filename again.
The real problem is, that your messages are out of order: you should never have a fan-out (that is: connecting a message outlet to multiple inlets), as this will create undefined behavior.
Use [trigger] to get the order-of-execution correct.
(Mastering [trigger] is probably the single most important step in learning to program Pd)
All,
Is there a way to have a minimum time to keep a stream open before it closes? For some reason, my stream is closing prematurely which is causing errors elsewhere. I need to keep it open to make sure ALL of the data is gathered, and then it can run the other code.
Thanks,
James
In the case that someone falls upon this question later, I ended up creating nested if statements to pull it off.
Basically, there is one statement that checks if the end tag is not found (for my code, the END of the ENTIRE data that I should be receiving is </SessionData> - So, I did if([outputString rangeOfString:#"</SessionData>"].location == NSNotFound). I created a string called totalOutput that would have the outputString added onto the end of totalOutput until the </SessionData> is found.
If anyone ever needs help, just go ahead and comment on here and I can give more information.
I am trying to stream sensor data from the iRobot Create. I get tuple out of range errors when I try
bot.stream_sensors(somenumber) and bot.poll_sensors(somenumbers). Whenever I input bot.sensors, I just get an empty array {}. I have even tried sending bot.sensors while pushing in on the bump sensor, still getting an empty array. I am connected to the bot through the Serial port with a serial-to-usb converter on my side. The only code before trying to get the sensor data is
import openinterface
bot = openinterface.CreateBot(com_port="/dev/ttyUSB0", mode="full")
Does anyone have an idea of how to solve this issue? Everywhere else just uses stream_sensors(6) and it seems to work fine.
P.S. I posted a question similar to this topic not too long ago, but no one responded. Not trying to spam, but now I have a more clear question and what the apparent-problem is so I thought I would try again.
I downloaded openinterface.py from this site: which included some sample programs. I'd suggest you take a step back, try the sample code, try to find other, more sophisticated, sample code and play with that first before moving on to your real code. You may be missing a step somewhere.
I may be a bit late to answer this, but for reference purposes. Directly controlling the iRobot is simplified greatly by using
Pyrobot.
