I found a strange phenomenon. When using STM8's TIM1 to generate PWM, there are problems at two specific points when updating TIM1_CCR. It can't be updated. It probably occurs when TIM1_CCR=230 and TI...
As the title says, I use the SIGNUM emulator ADM51 and develop with the keil c51 software. Currently, I cannot use keil for simulation and debugging. It is very inconvenient to use Wemu51 for debuggin...
