I'm testing Vidor 4000 with Arduino's sample code, "VidorTestSketch.ino", and I succeeded to make it run as what I expected. I changed SerialFPGA1 to SerialFPGA4 and checked that the string in SerialFPGA4.println("...") is output from D1 pin as it is configured in VidorUART.cpp.
That example shows that FPGA pin 33 is connected to A0 on MKR header pin and it must be connected as that.
But I couldn't find the information of pin connection between FPGA GPIO pins and MKR header pin or minPCIE slot, anywhere. I want to read the state of one of FPGA GPIOs thru A1 or A2. But there is no information about which FPGA GPIO pin is connected to A1 or A2. And how many GPIOs are configured in FPGA with VidorPeripheral library?
Where can I get that information?
Please anybody tell me about it.
