STM8S005K6T6 port and AD acquisition display control problem [Copy link]

I use STM8S005K6T6 MCU for AD acquisition. It works fine. But every time I run the AD program, it will affect the output of other ports. For example, the high and low levels of the PC1 and PE5 ports are not normal. But the output of the ports is normal when they are run separately. But the combination is confusing. Which expert can help me solve this problem? Please chat with me on QQ414924430. Thank you.

Check if the interrupt execution affects the timing of the output level of other parts. Check if the interrupt takes too long. Simplify it.
