USB DAQ
« on: March 20, 2014, 03:01:38 am »
Being new to the forum I'd like to know how we go about bldg a small DAQ.
The DAQ must have 2 bytes of dig Progmmble VB.NET I/O
2 Ch of MAX187 ADC simultaneous single sample on demand VB.NET
1 32 bit counter
Using PIC18F45K50.
I'll be pleased to open correspondence with an interested party.

For the USB communications, you could use virtual serial port, HID, or WinUSB. Microchip has example code for each of these.

Implementing HID will be much easier and faster than CDC (virtual serial port)
