Light Up an LED Overview The purpose of this tutorial is to light up an LED using a program, which will automatically turn off after 3 seconds. In all programming languages, the first program is called hello world, and today’s LED lighting tutorial is essentially the hello world of hardware programming, making it a very … Read more
The manual porting process is complex and tedious. First, use cubemx for quick configuration: First, print a message to the serial port: /* USER CODE BEGIN 2 */ printf("hello shxi\r\n"); /* USER CODE END 2 */ /* Call init function for freertos objects (in freertos.c) */ MX_FREERTOS_Init(); OK proves that the configuration is correct! Tasks … Read more
