I have a Mad catz mouse9 bluetooth mouse. It's software isn't very good. So I have been using ahk, with special keys programmed to shift + f12 or something (to emulate f22 etc. mad catz software does not support f22 directly)
This is not a very good solution, and sometimes causes problems.
So I wanted to not use mad catz software.
I have tried AHKHID's example 2 to find what calls are being made.
When I read for mouse I can get data for special keys, but they seem emty. so there is data being polled but I do not know how to differentiate between different keys
I have tried AHKHID_GetInputData but it seems to not work for mouses.
Is there somemethod to get raw data?
I have also looked for other HID devices connected, but they do not register anything.
I am not good at programming (or scripting in this case), so sorry for any stupid mistakes :)

I'm taking an advanced operating systems course. We're using full hardware emulation from qemu to develop our own basic operating system. What we're programming this week is the keyboard. Interacting with the keyboard controller over ports 0x60 and 0x64 in the appropriate way to decode scancodes works. Using our previously written CGA driver we can now type things and have them displayed on screen in qemu. One thing that doesn't work in qemu, but does work on hardware provided by the professor specifically for the course, is setting the speed and delay parameters of the keyboard. These determine how long you need to push a key until make-codes are sent repeatedly and with what frequency make-codes are sent once you pushed the key long enough. This changes how fast a character is printed repeatedly on screen when holding. We are all wondering what exactly is happening in qemu that prevents this from working in qemu. The easy answer: qemu doesn't emulate the set_speed (0xf3) command. The more interesting question: From where in the source code could one tell this is not going to work? Are there other commands not emulated by qemu? Why is set_speed not emulated by qemu?
Many thanks in advance
I am trying to make some custom firmware for a MIDI controller (AKAI LPD8).
There is an STM32F102R8T6 chip in the unit.
I am trying to reach it with a programmer to wipe it, but it seems to not be responsive.
Some information and thing I have tried:
The firmware that came with the unit works, so the chip is not broken
Removed the components connected to the programming pins (PA9-PA10 and PA13-PA14)
I am able to pull BOOT0 high and have it not run the main program, but I am however not able to get a life sign using either an ST-Link2(clone) connected to PA13/14, nor a USB to serial adapter connected to PA9/PA10, so I am not sure what mode it is in
The connection has been checked, and RX-TX etc is the correct way around (but also for the sake of trying it all, I reversed the connections as well...).
Tried both the STM32CubeProgrammer and stm32flash, but none connects.
I am actually not sure if AKAI have locked the chip in such a way that you cannot even do a full chip erase and use the chip for something new? The NRST pin is strangely not doing anything to the running of the firmware either when I try to pull it low.
Is there a way to reprogram these chips when they come off of a commercial product, or are they permanently locked?
Any solution/tips?
Many of the STM32 parts have "proprietary code read-out protection" (google PCROP) which but you might be lucky and they haven't enabled it in the option bytes. Read the documentation for that and the bootloader documentation and get a good idea of what you expect it to do if it is enabled and if it isn't.
If you have a scope, try watching the SWD/JTAG pins to see if there is any response from the device. (If you aren't even sure if it is in reset then scope the crystal if there is one).
If you haven't got a scope, you might be able to to verify what it is doing by seeing if it sets the pins and pull-resistors to how they would be expected to be in the bootloader mode, eg: UART TX should be high if it is enabled, even it it isn't transmitting anything. Put a strong pull-down (~1k) on there and see if it still reads high.
After hours of trying different ways of making it work (also tried the alternate mapping of the UART port), and probed the TX pin as suggested by Tom V to no avail, I have given up working on that specific chip and ordered an upgrade from the STM32F4 family instead to replace it with. A lot more power and useful peripherals.
A bit of a non-answer to the specific question. Frustrating to not have found out what was wrong (chip or approach) but being mindful of the sunk cost fallacy, I think it was best to just replace the chip with a fresh one and start development from there.
I need help, I'm desperate
During two weeks I have been working in my project, this uses serial port communication (a PIC serial board). I got to set the connection up, but I can not get data from the COM port. I've read some forums and the cause of the problem seems to be the incomplete implementation of System.IO.Ports class.
When I try to get data of the COM port, the event SerialDataReceivedEventHandler (represents the method that will handle the DataReceived event of a SerialPort object.) is not called or activated. I tried to resolve it but I don't find a definitive solution. I thought to prove a external DLL, but a friend told me that the problem will go on, in fact I did it and got the same problem: SerialDataReceivedEventHandler does not work. Also, someone recommended me using a secondary thread, although I don´t understand how to do it at all.
I wrote a program in visual C# and everything works fine. I'm intrigued.
I need to find a solution, some idea or good documentation. If there's someone knows something about it, help me please.
I need to understand the cause of this to continue.
Unity is based on Mono, and Mono doesn't implement completely the Serial class, in particular there are no notifications implemented (such as SerialDataReceivedEvent).
That's why it works in Visual Studio, and not in Unity.
Here are the differences between the Mono and complete .NET implementation of the Serial class :
Extract from http://www.mono-project.com/archived/howtosystemioports/#limitations
"Limitations
At the time of this writing, there are a a few limitations that one must take note:
1) There is no event notification for received serial data. If you want to receive data, one must set a timeout and watch for received data by polling ReadByte() when you think there might be data.
2) One must Read data in byte[] format only – there is no char[] support. You must do your own reading of bytes and translate that into your encoding.
3) DiscardNull, ParityReplace, ReceivedBytesThreshold are not implemented."
I think it happens because the Unity is based on Mono instead of .Net, and a pretty old version of it. You couldn't use Linq on iOS devices for a long time because of AOT bugs, and the localisation implementation is buggy (or at least it was in the previous versions of Unity I tried to work with). I wasn't even able to find the source of System.IO.Ports in the source of Unity's Mono fork, so it's surprising it compiles at all.
OK,
So we want our robot - roomba (the nice vacuum cleaner) to know it's location in a given room.
That means we have the map of the room and the robot is put somewhere and needs to know in a short time where it is located.
We saw a lot of algorithms - where the most relevant one was MCL (monte carlo algorithm) for localization of robots in space.
We are afraid that it is too big for us and don't know where to start from.
We would like to write the code in MATLAB.
So if anyone have any idea where we can find a code - we would apprecate it a lot.
We are open minded about the algorithm - so if you have a better one or something that might work, that will be great. That goes to the language we are writing it in.
Thanks.
Liron.
Interesting.
I've read a lot about trying to keep track of where the roomba is, but it seems like every system that has used only "internal" feedback from the roomba has ended disastrously. Meaning they try to keep track of the wheel locations etc... The main problem is that you can't take into consideration the wheel slip you get and will drastically change based on surface and other factors.
I would recommend using either a stationary based sensor that the roomba can locate from, on-board diagnostic sensors (such as a camera, wiskers, ultrasonic), or a combination of the two.
STAMP makes a great ultrasonic sensor package called the PING((( that can sense up to 6ft. I've used it up to 15 feet, but it works great in close proximity for mapping.
hope this helps!
Is there a way to simulate user activity on desktop on Windows? This is the situation: A friend of mine works from his home. His company recently decided to provide their employees with a communication tool which they have to keep running in the background. Apart from its main functionality it also has a very intimidating side effect: It tracks user activity. This means that the programm monitors keystrokes and mouse movements. If a user is idle for say 5 minutes or something, an icon next to his name indicates his idle status to all other users, much similar to instant messengers like skype for example. Now while this may be useful in IM programms, we both find it a bit disturbing in a work related context, for obvious reasons.
Doing some google search only gave me shareware links or cheating tools for MMORPGs. But maybe I searched for the wrong terms. My first guess would have been to have a small process running in the background which imitates keystrokes or mouse movement in regular intervals. But maybe there is another way to deal with this. (Oh, and complaining about lack of privacy to the employer is not an option ;) Also please note that I don't want to promote laziness or question an employer's rights over his employees.)
Any comments and help appreaciated. Thanks!
There is an easy way to make cursor move in C++.
its something like:
pos.X = 10;
pos.Y = 10;
I dont know if this is the best way, but it works.
If you dont want to program your own program, Im sure there are a lot of programs on the internet. You just need to google :) .
