usb-avr-cpld
A small experiment board with usb-connector, usb-serial bridge, avr controller & xilinx cpld
Board’s main parts:
- Ftdi FD232RL USB-UART bridge
- Atmel Atmega88
- Xilinx XC9572XL CPLD
Test FW:
The folder avr contains a avr-gcc project with test routines for the Atmega88 controller.
It checks for the interfaces to the other devices. At the moment, a simply uart loop to the FT232RL
is implemented.
The folder cpld contains a xilinx ise / ghdl project with test design for the CPLD.
It checks for the interfaces to the other devices. At the moment, putting a simple “10101” pattern on the gpio pins is implemented.
