Learn to use multiple UART modules in STM32 HAL by duplicating init code for UART1 and UART2, configuring pins as alternate functions, and enabling interrupt mode to transmit and receive.

The DMA module enables background data transfers by selecting stream and channel. Configure source and destination, transfer mode, size, increment, and optional FIFO, burst, and priority.

Configure the ADC to use DMA by enabling the DMA clock, selecting stream zero channel zero, and linking the ADC to the DMA for peripheral-to-memory transfers.
