- h3. Board's main parts:
-
- * Ftdi FD232RL USB-UART bridge
- * Atmel Atmega88
- * Xilinx XC9572XL CPLD
-
- h3. Test FW:
-
- The folder "avr":https://github.com/tmeissner/usb-avr-cpld/tree/master/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":https://github.com/tmeissner/usb-avr-cpld/tree/master/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.
