My 1602-LCD display random about stm32_timerinterrupt HOT 1 CLOSED

I have tried this STM32_TimerInterrupt, but why my 1602-LCD display any random character after few times.

and

#include "ESP32TimerInterrupt.h"

How can this mistake and/or hasty post happens?

As you know in programming, even a small mistake can create a severe headache, and sometimes is never found and fixed (such as Windows BSOD). This random character is a symptom of stray pointers and bad code.The origin can be anywhere, such as your code and/or one of many libraries you're using.

I have no time to deal with your problem as only you can figure out. Will spend some time only you prove that there is some bug of this library.

Good Luck,

from stm32_timerinterrupt.
