Implementing SPI Communication for Arduino

Hello everyone, Rabbit Brother is back! Today we are going to learn a super practical communication method – SPI communication. It’s like a “highway” between Arduino and peripherals, allowing data transfer to be fast and stable. Whether dealing with SD cards, displays, or various sensor modules, SPI is a great tool. Let Rabbit Brother guide … Read more

Practical Skills: SPI Flash Programming Algorithm for Any MCU with SWD Interface

Previously, I shared a document-based tutorial on creating an SPI Flash programming algorithm. However, feedback from users indicated that it was not very convenient to port to other microcontrollers. This post is created to facilitate the migration to various platforms. Application scenarios for the SPI Flash programming algorithm: 1. In an IDE environment, such as … Read more

Design Principles: A Discussion on SPI and API

Author: Happy Framework Original: https://www.cnblogs.com/happyframework/p/3325560.html Background My first encounter with SPI was while reading “The Art of Software Framework Design”. Later, I gradually discovered this way of organizing code in JDBC and SpringBoot. Here, I present a thought process on why we should distinguish between SPI and API. Starting from interface-oriented programming We introduced an … Read more

STM32G4 TIM+SPI+DMA Application Example

by
STM32G4 TIM+SPI+DMA Application Example

Currently, there are STM32 users developing products using the STM32G474R chip, where TIM1 is used for power drive, with TIM1 operating in center-aligned counting mode. There is a demand to trigger external ADC device sampling at the moment indicated by the arrow in the figure below during each cycle of TIM1. After the ADC completes … Read more

Why Does SPI DMA Circular Reception Fail When CRC Is Enabled?

by
Why Does SPI DMA Circular Reception Fail When CRC Is Enabled?

Someone is using the STM32G4 internal SPI configured as a slave full-duplex mode, using DMA for receiving. When the DMA is configured to CIRCULAR mode, problems occur where data transmission results in CRC verification failures and reception anomalies. If the DMA transfer mode is configured to NORMAL, there are no issues, and the received data … Read more

Can MCU Access Non-Standard SPI Interfaces?

by
Can MCU Access Non-Standard SPI Interfaces?

Currently, many precision analog-to-digital converters (ADCs) have a Serial Peripheral Interface (SPI) or some form of serial interface to communicate with controllers, including Microcontroller Units (MCUs), DSPs, and FPGAs. The controller writes to or reads from the internal registers of the ADC and reads the conversion codes. The PCB wiring for SPI is simple, and … Read more
