Hello, I contacted the manufacturer of the sound card device I am working with. They sent a data sheet, so I have the I/O pin numbers. They also sent me some software to read and write bytes to the GPIO registers. This was some source code and a compiled binary. Unfortunately the binary was compiled for a different Product ID than the device I have. Doubleplus unfortunately the source code for the .lib file which actually sends the data packets to the device is already compiled. I have the header file, but not the source.
So, to figure out the data packet format I think I have to do the following: 1) Recompile the demo code with the correct Product ID for my model of sound card 2) Use the demo app to send packets to the device and record USB data with a sniffer app 3) Pick out the data format 4) Write PyUSB code to do make packets Unfortunately the demo code is Microsoft Visual C++ (using MFC). What is the easiest way to recompile the source? Is there another way to examine the .lib file and find out how it works? Is there another way to use the .lib file with another program to send data to the device? I did ask the manufacturer for the source of the .lib file (just the code to write a packet to this device) but they didn't send it to me. It would actually be very useful to have the demo app working because I could test the GPIO function with the circuit I am building. If it doesn't work then there is no point in going further. Any help or advice would be appreciated.
