Some things can only be done alone. Some doors can only be passed alone. Some roads can only be walked alone. 1. Overview SPI: Serial Peripheral Interface. It is a synchronous serial bus interface specification developed by Motorola in the mid-1980s (with clock signal, controlled by clock polarity and clock phase for sampling, that is, … Read more
What is SPI SPI stands for Serial Peripheral Interface in English, which, as the name suggests, is a serial peripheral device interface. It was first defined by Motorola in its MC68HCXX series processors. SPI is a high-speed, full-duplex, synchronous communication bus that only occupies four lines on the chip’s pins, saving pin space and providing … Read more
Machine vision, as an emerging technology, has gradually been accepted by industry users in recent years.
