Understanding the Driving Capability of MCU's SPI Interface and GPIO: How Many Slave Devices Can SPI Connect?

Friends involved in hardware design should be familiar with the SPI interface and the GPIO ports of MCUs, and many have personally designed SPI interfaces. When designing, did you consider this important parameter? — The driving capability of the SPI interface and ordinary GPIO ports. Today, let’s discuss how to evaluate the driving capability of … Read more
