FreeRTOS Counting Semaphores Example with Arduino For demo, we will create an example using counting semaphore and Arduino. We will create two tasks such as Task1 and Task2. Both these tasks use serial communic

A port of FreeRTOS that runs on Arduino Samd21 boards - Arduino-FreeRTOS-SAMD21/examples/Basic_RTOS_Example/Basic_RTOS_Example.ino at master · BriscoeTech/Arduino-FreeRTOS-SAMD21
使用 ESP-IDF 的版本为release/v4.4,本来是想基于uart_eventsexample 自己来实现串口解析的逻辑,但突然发现FREERTOS竟然提供了一个组件FreeRTOS-Plus-CLI,可以实现串口解析的逻辑,并且和release/v4.4完美衔接,省去了自己编写串口解析代码的烦恼,只需要专注于上层功能逻辑的实现即可,简直是太方便了,可以说是开发神器。

FreeRTOS Create Tasks As discussed earlier, Arduino IDE provides a FreeRTOS library for ESP32. The FreeRTOS permits us to run multiple tasks on a single core or on multiple cores. For example, we can run a group of tasks on core0 and another group of tasks on core1 of ESP32. ...

The Arduinodelay()function has been redefined to automatically use the FreeRTOSvTaskDelay()function when the delay required is one Tick or longer, by settingconfigUSE_PORT_DELAYto1, so that simple Arduino example sketches and tutorials work as expected. If you would like to measure a short mi...
In order to demonstrate the use ofFreeRTOS task delete API function, we create a very simple example withArduino. We create two tasks such as Task1(LED1) and Task2(LED2). Example with Arduino 1. Task1 is inside setup function with priority 1. When it runs, it creates Task2 at prior...
