实现功能
{0x00,0x00,0x30, 0x00, 0x00}—“0000300000”
搜索到的C语言程序
#include
#include
int main(int argc, char *argv[])
{
unsigned char port[5] = {0x00, 0x00, 0x30, 0x00, 0x00};
char buf[20] = {0};
sprintf(buf, "%02x%02x%02x%02x%02x", port[0], port[1], port[2], port[3], port[4]);
printf("十六进制:\t%s\n", buf);
}
运行结果
这里直接使用了sprintf,在VC编译器中运行是对的
问题:在keil编写源代码时,如何将结果显示在串口助手中?
在有串口的keil文件中加入这一段,见下
#include
unsigned char port[5] = {0x00, 0x00, 0x30, 0x00, 0x00};
char buf[20];
void main(void)
{
P3M0 = 0X00;
P3M1 = 0X00;
P4M0 = 0X00;
P4M1 = 0X00;
P1M0 = 0X00;
P1M1 = 0X00;
P2M0 = 0X00;
P2M1 = 0X00;
Uart1_Init();
sprintf(buf, "%02x%02x%02x%02x%02x", port[0], port[1], port[2], port[3], port[4]);
uart1_printf(buf);
}
串口助手中:
错误!emmmm,继续百度,不行咱就Google
网上提供的代码看花了眼实在是太多了,到底哪个符合我的要求!!!???
再来一个!成功!
