本课程旨在教授 FreeRTOS 在 ESP32 上的应用。 **课程亮点：** * **为何学习 FreeRTOS？** * **免费开源：** 无需任何费用即可用于任何项目，并可获取全部源代码。 * **实时操作系统 (RTOS)：** 能够处理具有严格时间限制的数据和事件。 * **轻巧简洁：** 内核资源文件仅三个 C 文件，非常适合内存资源有限的微控制器。 * **广泛支持：** 已移植到众多平台，包括 Xilinx FPGA。 * **为何选择 ESP32 作为学习平台？** * **原生支持：** ESP32 的 SDK 直接使用 FreeRTOS，无需重新移植，提供稳定的学习平台。 * **强大的功能：** 集成 Wi-Fi 和蓝牙，适用于物联网应用，并拥有丰富的 peripheral 接口（I2C, SPI, UART, ADC 等）。 * **高性价比：** 体积小巧，价格低廉，便于爱好者 DIY。 **重要提示：** * 所有课程示例均在 ESP-IDF SDK ver4.4.1 版本上测试通过，其他版本代码可能略有差异。 * 使用非 ESP32C3 的普通 ESP32 开发板时，可能需要在 menuconfig 中将 FreeRTOS 设置为仅运行在第一个核心。
The first question for the freeRTOS on ESP32 lessons is why we need to study freeRTOS. The most important reasons are probably as follows:(1) First, it is totally free and open source. You no need to pay any fee for using it in your any projects. And you can get all the source code from it's official website;(2) Second, it is a "RTOS". "RTOS" means "real time operating system". It can processes data and events that have critically defined time constraints. (3) Third, it is very tiny and simple. The kernel resource files are only three c files. It is very fit for microcontroller which has limited ram or rom.(4) Forth, it is well supported. It has been porting on lots of platform, even including xilinx FPGA. The second question is why we study freeRTOS based on ESP32?(1) The first reason is the original SDK software of ESP32 is using the freeRTOS as its operation system. We no need to port it again. We will have a very stable platform to study all kinds of software features of the freeRTOS.(2) ESP32 is a very wonderful chip. It has internal flash and sram. It has the wifi and bluetooth function on the same chip. The wifi and bluetooth is a critical function for the "internet things" application. It also has other powerful peripheral interfaces, such as, I2C, SPI, I2S, UART, ADC, DAC, RTC, USB etc.(3) It also has a very small package size and very low price compared with other similar function chips. It is very easy to DIY products by hobbyist.NOTES:(1) All the course examples have been tested on idf sdk ver4.4.1 software. For other versions, the code might be a little different. (2) If you are using one regular ESP32 board, not one ESP32C3 board, you might need to change FreeRTOS running on two kernels to running on one kernel by setting "Run FreeRTOS only on first core" in menuconfig.
