Details
The TinyFPGA Programmer is a very simple USB-JTAG bridge designed to program bitstreams onto the JTAG pins of the TinyFPGA A1 and A2 boards.
It uses a PIC16F1455 USB microcontroller allowing the programmer hardware to be cheap.
Using the TinyFPGA Programmer Application you can program .jed files generated by Lattice Diamond.
Serial Protocol
The programmer firmware appears as a generic USB serial port when you connect it to a computer. GPIO pins on the programmer are controlled through this simple serial interface, encoded as 8-bit bytes with a command type field and data payload. The payload is typically a 6-bit bitmap representing the GPIO pins of the programmer.
