擎天柱学习：《8051U深度入门到32位51大型实战教学视频》，打卡
第三集 擎天柱 点亮LED灯，测试通过1、编译图片
2、源代码
#include "ai8051u.h"
void main(void)
{
P2M0 = 0;
P2M1 = 0;
while(1)
{
P20 = 0;
P21 = 0;
P22 = 0;
P23 = 0;
P24 = 0;
P25 = 0;
P26 = 0;
}
}
3、擎天柱
第四集 成功实现USB不停电下载，跟着冲哥步骤 添加库函数、添加USB库文件。
USB库文件操作好之后 注意都勾选，先用普通下载（先按住擎天柱P32不放，再按住POWER后松开，串口扫描那 识别出 USB-Writer），之后可以实现不停地下载
1、编译图片
2、源代码
#include "ai8051u.h"
#include "stc32_stc8_usb.h"
char *USER_DEVICEDESC = NULL;
char *USER_PRODUCTDESC = NULL;
char *USER_STCISPCMD = "@STCISP#";
void main(void)
{
P_SW2 |= 0x80;
P0M1 = 0x00; P0M0 = 0x00;
P1M1 = 0x00; P1M0 = 0x00;
P2M1 = 0x00; P2M0 = 0x00;
P3M1 = 0x00; P3M0 = 0x00;
P4M1 = 0x00; P4M0 = 0x00;
P5M1 = 0x00; P5M0 = 0x00;
P6M1 = 0x00; P6M0 = 0x00;
P7M1 = 0x00; P7M0 = 0x00;
usb_init();
IE2 |= 0x80;
EA = 1;
while (DeviceState != DEVSTATE_CONFIGURED);
while(1)
{
if (bUsbOutReady)
{
USB_SendData(UsbOutBuffer,OutNumber);
usb_OUT_done();
}
P20 = 0;
P22 = 0;
}
}
第五集 C语言基础
1、编译图片
2、代码
#include "ai8051u.h"
#include "stc32_stc8_usb.h"
#define u8 unsigned char
#define u16 unsigned int
u8 X = 20;
u8 Y = 0;
char *USER_DEVICEDESC = NULL;
char *USER_PRODUCTDESC = NULL;
char *USER_STCISPCMD = "@STCISP#";
void main(void)
{
P_SW2 |= 0x80;
P0M1 = 0x00; P0M0 = 0x00;
P1M1 = 0x00; P1M0 = 0x00;
P2M1 = 0x00; P2M0 = 0x00;
P3M1 = 0x00; P3M0 = 0x00;
P4M1 = 0x00; P4M0 = 0x00;
P5M1 = 0x00; P5M0 = 0x00;
P6M1 = 0x00; P6M0 = 0x00;
P7M1 = 0x00; P7M0 = 0x00;
usb_init();
IE2 |= 0x80;
EA = 1;
while (DeviceState != DEVSTATE_CONFIGURED);
while(1)
{
if (bUsbOutReady)
{
// USB_SendData(UsbOutBuffer,OutNumber);
if(X > Y)
{
printf("条件为真\r\n");
}
else
{
printf("条件为假\r\n");
}
//printf("X / Y =%u \r\n",(u16)(X/Y));
//printf("X %% Y =%u \r\n",(u16)(X%Y));
usb_OUT_done();
}
}
