Title: ym2149-test

The ym2149-test is a little firmware to check that the YM2149 & Arduino circuit is working properly.

Requirements

The following libraries are required:

• gcc-avr (or avr-gcc depending on the distribution)
• avr-libc
• avrdude

How to test the circuit

$ make
$ make flash

Common errors

If getting the following error message when trying to flash the chip (make flash):

avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0xff
avrdude: stk500_recv(): programmer is not responding

Try to change the baudrate to 57600 in the Makefile (1st line). Some models may accept faster transfer rates than others.
