SemiHOST-based mechanism is implemented in the IAR environment

In the development of MCU, we sometimes want to output some information to observe. Usually we can redirect the PrintF related implementation function in the standard C library, output through the UART serial port, or use the ITM mechanism via SWO output. This will implement the Printf function based on the SemiHost mechanism in the simple demonstration IAR environment. The STM32F4Discovery board used below, the hardware debugger is STLINK. Use it slightly after configuration. Be careful to include stdio.h in the code. Demonstration code: The configuration process is very simple, it is also very convenient to achieve, we can use it flexibly. , Read full text, original title: Example of Prinf based on semi-host mechanism Article Source: [Micro Signal: STMCU832, WeChat public number: smartmcu] Welcome to add attention!
