Bailey Asay developed a Peripheral Abstractions Testing Project for the Gaucho-Racing/Firmware repository, focusing on STM32G4 microcontrollers. The project established a reusable framework to validate key hardware interfaces, including SPI, CAN, GPIO, DMA, I2C, USART, and ADC, streamlining the process of peripheral verification in embedded systems. Using C programming and leveraging STM32 development skills, Bailey implemented baseline configurations that enable systematic testing of each peripheral’s functionality. This work provided a structured approach to hardware interfacing, ensuring that future firmware changes can be reliably tested. The depth of the implementation reflects a methodical approach to embedded systems validation.
