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

is global interrupt is always enable during startup, is that right ?, if yes, where can i find it? InHAL_Init();orstartup_stm32g474retx.s

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...

Thank you! Can you point to me, Where does the processor implement enable global interrupts? which file and which line:smiling_face_with_smiling_eyes:

hi JWactually, i'm sure slave is ready, because when i see the slave spi tx buffer is already loaded with new data then i start next master transmit manually, but the first byte is still 0xAA when master received, i think 0xAA is the last byte that ...

Thanks, i find this function “__HAL_RCC_SPI1_FORCE_RESET()�?，but if i reset spi by using this, do i have to initialize SPI again ?

hello. what function do i use to reset spi communication?is this the only way?

hi,No NSS activity from master, just three lines, slave send(hex) A5 06 00 40 00 02 0B BB 0B 00 AA AA AA AA AA AAbut master receive (hex) AA A5 06 00 40 00 02 0B BB 0B 00 AA AA AA AA AA everytime, looks like last AA is always in the spi tx register
