This article aims to validate the usage of the STM32 SPI interface using the W25Q16 storage chip. ●About Flash Chips 1. When writing to flash, it can only change from 1 to 0; during erasure, all bits become 1. 2. The minimum write unit for flash is a page; individual bytes cannot be written. 3. … Read more

Embedded Hardware Communication Interface Protocol – SPI (III) Analog Interface Application

2025-04-24 by boardor

Simply completing the simulation SPI implementation for various interfaces is obviously not enough just by capturing the signal timing with an oscilloscope. Although the signal output by the microcontroller as the SPI master is easy to capture, the data sent by the slave (i.e., the timing of the master reading the MISO signal) requires finding … Read more
