README
KiCAD/SN76489 arduino nano shield/README.mdEasyLab Muziek Editie
Dit is 'n Arduino shield vir KiCad om muziek mee af te speel met gebruik van SN76489 geluids chip.
Die Sn76489 gebruik 'n 4.0000Mhz clock wat, of hardware clock osscilator kan wees, of gegenereerd met FastPwmPin van Maxint-RD.
Features;
- I2C aansluiting.
- Gebruik arduino as clock op IO-poort 8.
- Speel musiek af met MmlMusicPWM ook van MaxInt-RD.
- Werkt met Arduino Nano, mega, Attiny85, D-MOS1 WiFi, Digispark USB, ESP8266-01 WiFi enz.
