2. Add an fputc function to your source code that writes to the ITM Port 0 register. The fputc function enables printf to output messages. struct __FILE { int handle; /* Add whatever you need here */ }; FILE __stdout; FILE __stdin; int fputc(int ch, FILE *f) { if (DEMCR &...
二、标准库(不需要打开MicroLIB) 2.1 修改usart.c文件 #include<stdio.h>/* 告知连接器不从C库链接使用半主机的函数 */#pragmaimport(__use_no_semihosting)/* 定义 _sys_exit() 以避免使用半主机模式 */void_sys_exit(intx) { x = x; }/* 标准库需要的支持类型 */struct__FILE{inthandle; }; FIL...

This is a recreating of the powerful function printf in the C programing language. This project is far more stripped down than the original printf but it also has some rules that make this project very challenging. I will add a link to the full set of restrictions when the project nears ...
