This example describes how to use DMAC to transfer data from Memory to UART.
In this example, Main clock is from PLL clock and it is configured at 96MHz. The PLL clock is based on 8MHz HSE. APB1 and APB2 clock is from Main clock.
In this example, memSrc is used as the source of DMA transfer, and UART2->THR is used as the target of DMA transfer. When this example runs, it will print out relevant information through UART1, and enter any character to start DMA transmission. When the DMA transfer is completed, UART2 will send out "Hello world!!!".
In order to make the program work, you must do the following :
Run the example
