DMA is a commonly used feature in embedded real-time task processing. Using DMA for UART data packet transmission can significantly reduce CPU processing time, preventing excessive waste of CPU resources, especially when transmitting a large number of data packets (such as high-frequency command transmissions). Brief Introduction to DMA DMA: Direct Memory Access. In simple terms, … Read more

1. UART: The Art of Asynchronous Communication As Qiu Qianzhang from “The Legend of the Condor Heroes” said, UART is like my lightness kung fu, gliding over the water. If you want to cross the river (communicate), you need to set up markers in advance, and your steps should be fixed according to the distance … Read more
Today, I will share with you the hardware UART peripheral debugging output mechanism under IAR. In the embedded world, outputting print information is a very common auxiliary debugging method. With the help of print information, we can easily locate and analyze program issues. There are many ways to implement print information output in embedded application … Read more
