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
To start, why do I write IIC instead of I2C in my article? Because they are the same thing, and it’s easier for me to write as IIC Today, we will look at how to use IIC in the STC library functions. There are three sets of pins available for us to choose from, and … Read more
