Re: [fpc-pascal] USB Human Interface Devices

[Jean SUZINEAU]

I'm not an expert, but a few years ago I made small project to read data from an Arduino through USB port. The project was running on Raspberry Pi, on Windows it can be more tricky( I'm not sure, but I think a device driver is needed): https://github.com/jsuzineau/pascal_o_r_mapping/tree/master/electronic/Arduino/HeartRate ,  see Arduino_Special_Raspberry_Pi.lpi It seems I used TLazSerial component.
