BSP video tutorial issue 21: easy one key implementation of serial port DMA variable length transceiver, support bare metal and RTOS, including MDK and IAR, which is more convenient than stm32cubemx (

Video tutorial summary post ：https://www.armbbs.cn/forum.php?mod=viewthread&tid=110519

---

We use CMSIS Pack A key to create , Support MDK and IAR, You don't need to do bottom research , Just care about the upper application , And support bare metal and RTOS How to play .

The advantage is simple and easy to realize , The disadvantage is that after I like this game , Will be unable to extricate themselves , I'm no longer willing to devote myself to studying the source code .

BSP Video tutorial 21 period ： Easy one click serial port DMA Send and receive with variable length , Support for bare metal and RTOS, contain MDK and IAR Two ways to play , Than STM32CubeMX It's convenient

IAR9.3 Of CMSIS Pack A key to create ：

 

 

MDK RTE A key to create ：

 

API file ：

 

Reference material ：

1、 Examples produced in the video process （ Including bare metal and RTOS edition ）：
link ： Baidu SkyDrive Please enter the extraction code    Extraction code ：61y7

2、 be based on V6 Of CMSIS-Driver Serial port application , Support 8 A serial port DMA Send and receive with variable length , Than CubeMX And save trouble

3、 Friends in the jar “ Jiajiaxu ” be based on STM32CubeMX Created serial port DMA Play for a long time , Also very good.
