Understanding Interrupt Systems in Microcontrollers and RTOS

Understanding Interrupt Systems in Microcontrollers and RTOS

Abstract: We encounter many operating systems in our daily lives, such as Windows, Android, iOS, and Linux. Microcontrollers also have their own operating systems known as Real-Time Operating Systems (RTOS). So, what are the differences between these real-time operating systems and the ones we commonly use? The operating systems we frequently use are actually non-real-time … Read more

Do UART Serial Ports Need DMA for Transmission?

Do UART Serial Ports Need DMA for Transmission?

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
