How to Setup DMA using Registers
In STM32, there is a dedicated bus for the DMA, and this helps keeping the CPU free for other operations….
How to Setup UART using Registers in STM32
The most important Register used in UART configuration is UART Control Register 1 (CR1). Most of the Configuration is done here.
UART DMA with IDLE Line Detection
HAL_UARTEx_ReceiveToIdle_DMA is used to receive the data using the DMA until, an IDLE event occurs, or all the data has been received…
