STM32F103 SPI Slave strategy

I use STM32F103C8T6 as SPI slave and want to send data on request by master.The master sends to the slave a byte, which has to be used to decide, what has to be doneor what data data has to be sent to the master, and a fill byte which is neededto shi...

Is there a HAL example of a memory to memory, or memory to peripheral DMA operation triggered directly by a TIMER event (not via a timer ISR) on the STM32H7?

I've read a ton of app notes, the STM32H7 reference manual, posts here, and I can't figure out how to have the timer UP event trigger a DMA operation. I'm sure this is obvious to someone with more understanding and could be gleaned from other STM32 m...

STM32G474 - UART interrupts keep firing when they should not be enabled

I am using USART2 on the G474 processor, and I only want the TXE and RXNE interrupts to fire. To do so, I wrote the following: //Enable/set the TXE and RXNE interrupt bits __HAL_USART_ENABLE_IT(&husart2, USART_IT_TXE); __HAL_USART_ENABLE_IT(&husar...

im using STM32F103C8T6 controller and im testing ADC for multiple channels (2 channels) but im not getting voltage when im using multiple channels but im getting voltage when im using single channel. why it is not working for multiple channels?
