Synth engine for esptiny86. this module is largely based on MicrobeModular's Equation Composer ported to esp8266 with full featured Audio Design tool https://esptiny86.github.io/espnode86
- Make sure your Arduino Ide at version 1.8.6 or more
- Add https://esptiny86.github.io/espboard8266/package_espsynth_index.json to board url on Arduino preferences
- Install Espsynth86 from board manager
- Download Espsynth library latest version from https://github.com/esptiny86/espboard8266/tree/master/library then install to Arduino > Sketch > Include Library > Add Zip file
- Choose ESPSYNTH Modules from Tools > Board > ESPSYNTH Module > Wemos D1 etc..
- Open example sketch
There are two methods for generating sound with ESP8266
-
PDM - Pulse Density Modulation
-
DAC - Digital Analog Converter (tested with PT8211)
To choose between mode uncomment in synthmodule86.ino file
define USE_PDM
- Inspired by Teensy, design tool is also available https://esptiny86.github.io/espnode86

//declare
NeoPixelBus<NeoRgbFeature, NeoEsp8266BitBang400KbpsMethod> neoPixel(NEO_NUM_LEDS, NEO_DATA_PIN);
RgbColor green(0, 128, 0);
//setup
neoPixel.Begin();
neoPixel.Show();
//update
neoPixel.SetPixelColor(i, green);
#include "ESP8266WiFi.h" // wifi header only needed to turn it off
void setup() {
WiFi.forceSleepBegin(); // turn of wifi to reduce power consumption
}
- Install Arduino IDE then install esp8266 from board library
- Open and configure "Makefile" file, then on command prompt/terminal type Make (the Makefile will auto discover your Arduino IDE and Libs))
- Nodemcu Lolin use BOARD = nodemcu
- Wemos D1 use BOARD = d1_mini
- Qt Creator is optional but it is recommended for developing further with espsynth86
- Edit project.include to your pathto get Intelisense in QT Creator
