这段函数调用了IAR Embedded公司提供的标准库函数stdlib.h中的atoi函数,atoi函数功能的描述是/*convert string to int*/,即把字符串直接强制转成整形数据。本系统上位机与下位机之间的通信协议由我们专门针对性地设计,其中字符串头部带有长度不能预知的命令字节,因此调用atoi函数前还需要判断该数据
* @return 对应的字符串 ***/voidconvertToDecimalString(uint32_t input,char*output,uint16_t length) {charresult[100]; sprintf(result,"%f", (float)input/length);//将整数转换为字符串strcpy(output, result); printf("output %s\r\n",output); } 上面的功能就是将整数数值根据小数点转出浮点型数...

通过Clion进行嵌入式开发一、工具安装1、安装Clion因为众所周知的原因,Clion的安装就不解释了,有需要的同学自行检索 2、安装STM32CubeMX正常去官网下载最新版的安装就行了: https://www.st.com/en/development-…
