Applications

Digitally Controlled Oscillator

Makes use of the RMT or LED PWM peripherals to accurately construct a clock signal of the specified frequency. Supports frequency ranges from < 1 Hz up to > 10 MHz.

Frequency Counter

Determine the average frequency of an incoming clock signal. Accuracy is determined by sampling duration.

Christmas Lights

Pretty SPI-controlled LED lights with numerous patterns and colour fades. Intended for use with APA102 or SK9822 LED strips. Remote control is provided over MQTT, and with a bit of configuration the lights can be controlled via TouchOSC on an iPhone or iPad.

Pool Control & Monitoring

An application for the monitoring of a swimming pool solar heating system, consisting of an ESP32, five DS18B20 temperature sensors, a TSL2561 light sensor, a ATtiny84 I2C slave for switch logic and pump control, a 16x2 Character LCD, and MQTT communications to a Raspberry Pi running a TICK stack with Grafana for time series visualisation.
