The firmware allows creating a device with a easily configurable functionality including inputs, outputs, ADC, pulse counter/generator, I2C, external sensors.
I’ve placed all features on the separate page. It is too long.
- The status LED indicator works now.
- The firmware supports up to 8 GPIO inputs or outputs.
- The “switch” mode for inputs.
- Pull-up, Pull-down, Tri-state options for inputs and outputs.
- Analog inputs.
- Internal temperature measurement.
- Source voltage measurement.
- UART (only text commands between an external device and a host, look at README.txt).
- Some environmental sensors (DS18B20, BMP280, BME280, DHT 11, DHT 22, DHT 12, AM2301, Sonoff SI7021, MHZ19, SenseAir S8, Sensirion SPS30).
- SI7021 (I2C), CCS811
- PZEM-004T (Energy Monitor Sensor), BH1750 (Ambient Light Sensor), INA219 (DC Voltage/Current Sensor), INA3221 (3-channel DC Voltage/Current Sensor)
- Pulse generator.
- Pulse counter (infinite, resettable, interval).
- PWM (hardware, up to 32 kHz).
- PWM (software 3 kHz).
- Bi-stable relay.
- Watchdog timer.
- Configurable default reporting interval.
- Expert options (model ID, manufacturer info, network key, etc.).
