@[toc] Impact of SPI Communication Modes on DMA Controller Configuration Strategies Insert image description here 1. Introduction The Serial Peripheral Interface (SPI) is a synchronous, full-duplex serial communication protocol widely used in embedded systems for data exchange between microcontrollers and various peripherals (such as sensors, memory, and display controllers). Although its physical layer is defined … Read more

The Simplest Way to Program SPI FLASH

The Simplest Way to Program SPI FLASH

Today, a customer asked us whether the programming speed of our SOP8 Flash chip would increase if the QE=1 setting is applied. Let us revisit the concept of SPI Flash chips. SPI FLASH typically supports the following communication modes: Standard SPI (Single/Dual/Quad) 1. Single SPI (Single Line Mode): Uses IO0 (MOSI) to send data, IO1 … Read more
