It took a long time, and now I finally finished welding the physical object. When burning, I found that I bought the wrong chip. I bought the STC10F08XE chip, and the chip I simulated was the STC89C51 chip. I bought the upgraded version. Then when the program was running, it was different from my proteus simulation. It can be seen that it has some similar rules to what I designed, but the speed is much faster than what I designed. But I think I connected an external 12M crystal oscillator, and when burning, I also saw that the current crystal oscillator is 11.98, which is very close to 12m, but why is it so fast? I modified the delay setting in my program, which is a little slower, but still fast. There was a four-second yellow light flashing at the end, and it was gone directly. Can anyone help me with what to do next?

This is a program, this is a traffic light program with an indicator light. Thank you

Well, let's take a look at the parameters of the new chip. There may be some differences, so please calculate it carefully and confirm it.

The STC10F08XE chip that the OP bought is a 1T MCU. Compared with the traditional 12T MCU such as STC89C51, the instruction running speed is 8-12 times faster at the same crystal frequency. Therefore, the soft delay also needs to increase the corresponding time.

I modified the corresponding delay program, 10 series of one second delay, but it is still relatively fast

You can hang up an oscilloscope and adjust the delay

Check whether the crystal oscillator is normal. The frequency of STC is fixed.

It is recommended to read the stc manual and examples carefully, it should not be too difficult.
