STM32CubeIDE live expression can not be changed in real time, this is a very useful function, ST engineer should consider it, because ST's competitor TI's CCS IDE are much better in this, ST should catch up

i am using NUCLEO-G474RE board, TIM1 to output PWM wave, it works fine ,i can see the pwm wave through scope, but when i use HAL_TIM_PWM_Stop(&htim1, TIM_CHANNEL_3);HAL_TIMEx_PWMN_Stop(&htim1, TIM_CHANNEL_3);to stop PWM , there is a attenuated wavefo...

Use STM32F405's SPI + DMA as a slave, circular mode, DMA 16bytes interrupt, but every time send 16bytes to master, the first byte is always the byte that last frame's last byte , it looks like spi tx register is not clear, always contain the last by...
