STM8 simulation running swim comm timeout-EEWORLD

Collect

There are many reasons for the program to run away. Let me talk about the situation where there is no problem with the program but the program runs away inexplicably.

Why do we say the program is fine? First of all, it compiles successfully, and secondly, we have configured the registers correctly, but it still runs wrong.

Especially compared to the STM8S103F3 and other microcontrollers with only a pitiful 8K storage space, it is really painful. Okay, no more nonsense, based on my experience:

Use IAR platform, COSMIC is very bad, I advise you not to use it.

1. The debug mode optimization is set to none. If the program still crashes after compiling and running under this condition, it may be due to the Option byte setting problem. For example, if you use the PWM function of TIM2_CH1, but your Option byte is not set, the program will crash when running (this is the first time I have encountered such a weird MCU).

2. If the program is really large, you need to set the optimization to middle, so be careful. IAR's optimization has some minor issues. Although middle can be compiled, it may crash when downloaded. Be especially careful. The solution is to optimize the code and try to get a usable version with optimization set to none, and then slowly add other code, otherwise you will end up with a very ugly death!

About the difference between i2c and spi protocols for debugging stm32 and stm8 (51 microcontroller)

When debugging the STM32's i2c and io ports to simulate the spi protocol, I found that timing is critical. STM32 can implement i2c or spi protocols at 72M, but it does not mean that the same code will run successfully on a 51 microcontroller, because the 51 microcontroller has a maximum speed of 8M, so there will be ma

About the failure of using IAR software stlink to download stm8 program

I used to use IAR normally, but this time I used stlink to download, and stlink could not download for unknown reasons. I turned off the power and restarted it. Sometimes it worked, but sometimes it really did not work. The prompt message was as shown in the figure below. Failed to initialize communcation with hardw
