都放假了，你淘宝上买个如下工具烧录

如下：第三方 USB 转串口，隔离锗二极管必须加

chen***

还是不能下载

神***

连接到电脑的详细的原理图，你没发上来，这部分电路可能有问题，
我们已放假，你抓紧淘宝买个我们的工具，马上过节了，快递都是问题

Problem with STC8G1K08A
After the firmware, the controller does not start.
  The code:
#include<reg51.h>

sbit OUT2 = P3^3;

void Delay500us()                //@11.0592MHz
{
        unsigned char i, j;

        i = 6;
        j = 93;
        do
        {
                while (--j);
        } while (--i);
}


int main () {
       
        while (1) {
               
       
                OUT2 = 0;
                Delay500us();

                OUT2 = 1;
                Delay500us();       
}
        }

The reference manual for STC8H in English is available here: http://www.stcmcudata.com/STC8F-DATASHEET/STC8H-EN.pdf


Please refer to section 9 I/O Ports. You have to configure your MCU IOs before using since all the IOs (except P3.0 and P3.1) are in high-impedance by default. For instance, at the beginning of your main function, add:

P3M0 = 0x00; P3M1 = 0x00; 
复制代码

In addition, if you have any further question, you can enter the relavent mod from the index (click the bold text next to bubbles in gray or yellow) and then click "发帖" button with blue background (since it is a picture so it won't be translated). That means creating a new thread instead of replying a current one.

See STC8G manual here: www (dot) stcmcudata (dot) com . Search STC8G, and here is an item named "STC8G系列英文用户手册". Sorry for my last reply (currently security check pending ince it contains url) gave that for STC8H.
