Tiny ESP32-C3 development board has USB support for serial communication, but it's not work in Platformio without by default. Here is simple solution to fix ESP32-C3 with Platformio.

Let's take a look at the simple example of using interrupt from hardware timer to generate signal at the one of the GPIO pin.

How to start with the new interesting ESP32C2 (ESP8684) SoC using modern and convenient VSCode IDE.

Fixing incorrect predefined XTAL (onboard crystal) frequency, that cause incorrect frequency of output PWM signal and rubbish charactersin debug terminal.

If paths to your library files doesn't specified in the STM32CubeIDE (Eclipse) project properties (both source and include) the project will be unable to compile?.. Here is clear steps to solve this problem with example ?.

This simple library give you a chance to using buzzer as sound notification with the possibility to set number of beeps and period between them.

Setup is very easy, because it's fully compatible with HAL and Cube code generator, all you need it's config chosen pin and set label BUZZER. And here is example of use:

Buzzer_Go(TBUZ_100, TICK_2);
