Intro
I still have a OPL2 board laying around that I wasn't using for anything at all.
Dreamer came up with the idea of using it as a theme song player for when members enter the space. Of course, it has to be IoT.
OPL2
The OPL2 is a FM-synthesizer created by Yamaha, and was widely used in a lot of sound cards and several arcade games. It has 9 channels, or 6 channels when you are using the 5 percussion instruments. The chip has a characteristic sound due to how it produces the waveform.
For more information on the chip, check out the Wikipedia article.
Using
- ESP8266 (Wemos D1 mini)
- OPL2 Audio Board
To-do
Replace the LM386 (op-amp) with a new one as the current one seems to be broken.New ones ordered from FrancePerhaps place everything on a PCB?- Look into adding a cap between VCC and GND to get rid of some hum
- Write a UDP protocol for directly interfacing with the registers of the synth (So it can actually play DRO)
Code (git)
SOON.
