Summary
👤
Senior🎓
Top SchoolStephen Caudle is an embedded systems engineer and founder with 11 years of professional experience building low-level device drivers, firmware, and board support packages for SoCs and microcontrollers. He has deep hands-on expertise with C/C++ and ARM platforms, practical hardware debugging skills with JTAG, oscilloscopes and logic analyzers, and a working knowledge of PCB schematics and layout. At Qualcomm he modeled PCIe and IO subsystems and built fast-forwarding/checkpointing tools to accelerate long-running simulations, and his open-source contributions include strengthening SPI support and nRF51 HAL drivers in widely used projects such as ChibiOS-Contrib and py-spidev. Now running his own consulting practice in Raleigh, he combines systems performance analysis with pragmatic firmware delivery for clients, often uncovering subtle hardware–software interactions that others miss.

doceme/py-spidev
Apr 2015 - Nov 2022
Role in this project:
Back-end Developer
Back-end DeveloperContributions:1 release, 38 commits, 34 PRs in 7 years 8 months
Contributions summary:Stephen primarily contributed to the `py-spidev` repository by addressing compatibility issues and enhancing the library's functionality. They fixed memory leaks, resolved build errors for Python 2.7, and added macros to support Python 3. Furthermore, the user improved the code by refactoring data handling with the PySequence_* functions. The user also introduced new features and adjustments, such as the addition of a 'read0' flag to improve interaction with SPI devices.
ChibiOS/ChibiOS-Contrib
Jul 2015 - Sep 2015
Community contributed code (ports, drivers, etc).
Role in this project:Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:11 commits, 11 PRs, 9 comments in 1 month
Contributions summary:Stephen primarily contributed to the low-level drivers and hardware abstraction layer (HAL) for the Nordic nRF51 microcontroller within the ChibiOS-Contrib repository. Their work included adding bitfield definitions, cleaning up existing PAL (Port Abstraction Layer) drivers, removing unnecessary code, and adding support for various peripherals like SPI, EXT, ADC, and GPT. These contributions focused on enabling and enhancing the functionality of the ChibiOS RTOS on the nRF51 platform.
