Hello, I received SN76489 chips so I updated my hardware VGM player with one of them and I almost had the pleasure to get it working on my first try (everything was ready from the code to the electronics) but I now have a very strange issue with the noise channel. Before going any further, I've to s...

@TmEE co.: Thanks for the info. I forgot about the internal clock division /144 and the PCM maximum rate you found is very interesting. @KanedaFr: I didn't use LUFA. The Atmel is programmed in plain C with avr-gcc. But LUFA seems to be very nice ! I should look at it ! Your idea is very nice, but, a...

Yeah, I think you're write about the YM sample rate because when I first tried the PCM audio experiment, the chip was running at ~7.67 (as usual) and I had cracks in the output, then I thought I was sending data too fast, but, after overclocking it a little, the cracks disappeared. It was easy to ob...

Hi guys,

I think I made a nice hardware implementation which could be used to experiment a little (undocumented registers, etc...). I just posted this : viewtopic.php?t=1122

Please tell me what you think

Thanks a lot !

Hi guys, I just finished a first version of my project. It uses a Teensy2.0++ board. I wrote a custom VGM file streamer (PC side) which sends 64 bytes data packets to the Atmel µC over USB with the RAW HID protocol (no drivers to install) into a circular buffer. The VGM file format is very well thou...

Hi everyone ! I'm currently working on a hardware implementation of the YM2612 chip. My goal would be to make a MIDI synth with multiple YM2612 chips inside. My first circuit is a very basic implementation with a Teensy++ 2.0 board but for the moment, it doesn't work. Since I don't have a real Genes...
