I am having all code with me (https://drive.google.com/drive/folders/1hKyy2O2HLyh9o4wxKsPFoyXOMyaorkv7)

Getting USB Time out error while replicating this into CY8CKIT-059

I managed to organize a CY8CKIT-059 board and have spent 2h to try out the software I’ve found at your link of Google drive:

· The software has been developed on a CY8CKIT-050 board according to Olav’s documentation (page19/20), so it might happen that on CY8CKIT-059 board some strange behaviors occur due to missing devices like the missing LCD panel. I would recommend to use same hardware as Olav.

· I was able to compile and download the firmware to my CY8CKIT-059 board, I was able to connect to the USBUART COM interface and I was able to send commands via HTerm to the board, I got an echo as response. I got no kind of “USB timeout”

· I’ve seen that there is also a Python script, guess that this is used to control the board via USBUART COM interface. As I can communicate with the board not using the Python script, I expect that the issues are within the Python scripts or in the way of control of the board via the Python script. Also I would expect that the “USB timeout” may be a message out of the Python script.

As Python script is completely outside of my knowledge, I cannot help here anymore. If I would have the task to get it running, I would first use HTerm to get it running manually by typing in commands and then further try to understand and debug what the Python script is doing

The code in this repository refers to a specific configuration of the FW present inside the PSoC board. In particular, it tries to connect to all proximal boards by sending them a 'v' character. Then, the PSoC is programmed to send ''HeartSounds$$$' after the receival of the 'v' character. Indeed, the python script looks for that string with a certain timeout.

If you can use Hterm, i would suggest either to program the PSoC to recognize a character such as 'v' or to remove the part of the script which checks every COM ports to use the one assigned to your board
