What SPI and I2C Bare Metal does

SPI and I2C Bare Metal shows how to implement master-mode SPI and I2C transactions without a HAL. Use it for sensor register reads, flash/display bring-up, and debugging NACKs, CPOL/CPHA mismatches, or stuck bus lines.

SPI and I2C Bare Metal is cataloged under Automation on DirSkills. SPI and I2C Bare Metal comes from a repository tagged ai-agent-skills, build-systems, c-cpp-toolchain, compilers and cross-compilation.

Documentation

README

Excerpt

SPI and I2C (Bare-Metal)

Purpose

Implement SPI and I2C master drivers for sensor and memory chips: clock configuration, phase/polarity (SPI), START/ACK sequences (I2C), and common register-oriented transaction patterns.

When to Use

Reading an I2C sensor (WHO_AM_I register)
SPI flash or display bring-up
Debugging NACK or stuck SCL
Replacing HAL_I2C/SPI with minimal code

Workflow

1. SPI master (STM32)
