Stm32cubeide printf

printf(), which is known as stdout, is a popular and common debugging tool. There are a lot of different software development environments that will work with the STM32 line of microcontrollers. This function accepts two arguments of type pointer to char or array of characters and returns a pointer to the first string i. i also use an STLink clone modified with to use the SWD's SWO debugging via adding an override for the _write() function in my main. Redirect printf() to UART on STM32 microcontroller - STM32HAL_printf_uart. Clock configuration Configure the system clock as 216MHz. 在对printf重定向之前,一定不要有printf,否则程序马上跑飞。 在main函数之前加上如下代码对串口进行重定向,当然,串口一定要初始化之后再用printf,否则程序虽然不会飞,但是printf也不会有结果 注意1: stm32cubeide没有usart的库函数了,由于usart逐渐被淘汰,stm32的HAL库只留下了uart的库 ; 注意2: stm32cubeide移植printf函数与keil移植printf函数不同的是,keil可以勾选lib库,由于stm32cubeide问世不久教程很少,并不能有效的重定向printf函数,可能是我的编译器配置有问题 STM32でUARTをやってみる6 (float型printfをUART経由で出力) STM32. My setup : I have reimplemented the _write method: The printf is still not working.
