The Cute ESP32 Pocket Wardriver! Based on the Xiao / QT-Py boards.

This implements an i2c slave with a register map of 256 bytes in sram. The slave supports multi-byte writes and reads. It uses the "Wire" library.

A simple program for controlling a PWM fan from a microcontroller with Rust

Two relay channels are controlled with an Adafruit QT PY running USBTMC

Custom PCB with SAMD21 QT PY controlling TWO ADG1606BRUZ 16 input muxes!

Arduino library DAC control using a serial (USB) terminal

Custom PCB with SAMD21 QT PY controlling TWO ADG1606BRUZ 16 input muxes! This board is 30% smaller than V3 and uses a single 16x2 pin header.

A software defined pattern is given by serial input and then driven on a gpio pin. Fastest pattern has 2us intervals, but any interval may be specified.

Documentation. This example for production-ready. However, it does not include local server and api server call (multithreading or run-subprocess)

The rising and falling debounce duration between two pins is measured. Maximum debounce duration is 4 seconds rising or falling (no limit on how long both signals can be high for).

A simple program to set the speed of a fan using the RP2040 QT Py and the EMC2101 fan controller
