Turbosound AVR AY Emul v1.0

TurboSound Emulator on 2x Atmega8A chips based on http://www.avray.ru project.

How to upload the firmware

Due to there is no room for ISP connectors on the board, you need to solder a few wires directly on the board and connect them with your programmer:

• GND, VCC and RESET signals
• CK, SO, SI as SCLK, MISO and MOSI signals
• Do not forget to bridge solder jumpers

Uploading:

Use avrdude and USBAsp programmer to upload firmware for each chip:

avrdude -p atmega8 -c USBasp -U flash:w:emul_230_turbosound_chip0.hex -U eeprom:w:Conf_parallel_24MHz_1_75Mhz.hex -U lfuse:w:0xCE:m -U hfuse:w:0xCF:m

avrdude -p atmega8 -c USBasp -U flash:w:emul_230_turbosound_chip1.hex -U eeprom:w:Conf_parallel_24MHz_1_75Mhz.hex -U lfuse:w:0xCE:m -U hfuse:w:0xCF:m
