Writing portable microcontroller libraries is hard. The first issue that I run into is that it is hard to set up a toolchain and debugger for a specific microcontroller to run builds from the command line. Possible, but takes a
ESP32: 1 MHz clock signal to output pin
code /* Example: Generate 1 MHz clock signal with ESP32, note 24.3.2020/pekka ESP32: LEDC peripheral can be used to generate clock signals between 40 MHz (half of APB clock) and approximately 0.001 Hz. Please check the LEDC chapter in Technical
Configuring micro-controller WiFi with Android phone’s LED flash
Introduction The “Gazerbeam” library enables configuring micro controller’s Wi-Fi network name (SSID) and password (PSK) using a LED flash of Android phone, etc. The phone needs APP to blink configuration information, the example Android Java application named “blinky”. A phototransistor
