The Raspberry Pi Pico is a very powerful microcontroller, especially when compared to an Arduino Uno. Yet most of the time we reach for a board to test with, we pick an Uno! This is because the Uno is easier to prototype with. Well, today we'll change all that and build three differ...

First off, we will need a better software interrupt library. You should erase the TimerOne library you installed in Lesson 28, and replace it with the one here: https://github.com/PaulStoffregen/TimerOne The video shows how to get the library if you are not familiar with github. The vi...
Why do we need this TimerInterrupt_Generic libraryFeaturesThis library enables you to use Interrupt from Hardware Timers on supported Arduino boards such as AVR, Mega-AVR, ESP8266, ESP32, SAMD, SAM DUE, nRF52, STM32F/L/H/G/WB/MP1, Teensy, Nano-33-BLE, etc....
Timer interrupt execution rather than in theloop(): ❌ No real performance improvement Sine wave lookup table implementation Implement Space Vector Modulation method : Pure SVM Implement Space Vector Modulation method : PWM SVM MCU support
The nature of a Linux based embedded computer means that tasks such as writing to the disk or checking the time might interrupt some critical behaviour of your system. If you need to have control over this for say balancing a robot or controlling a machine tool then you will need to have...
You can use thetimer, waking up your ESP32 using predefined periods of time; You can use thetouch pins; You can usetwo possibilities of external wake up: you can use either one external wake up, or several different external wake-up sources; ...
The ESP32 comes with 2 Xtensa 32-bit LX6 microprocessors: core 0 and core 1. So, it is dual core. When we run code on Arduino IDE, by default, it runs on core 1. In this post we’ll show you how to run code on the ESP32 second core by creating tasks. You can run pieces ...
