Summary
👤
Senior🎓
Top SchoolCharles Steinkuehler is a seasoned embedded systems and hardware leader with 26 years of experience, now serving as Director of Technology for NDI at Vizrt. He combines deep expertise in ARM NEON optimization, Linux embedded design, FPGA (VHDL) and mixed-signal high-speed hardware with hands-on experience in PCI/PCIe and video circuitry from decades at NewTek. An active open-source contributor, his low-level work on projects like machinekit (PRU encoder support) and omap-image-builder demonstrates practical mastery of real-time control and embedded image tooling. Based in Topeka, Kansas, he pairs systems-level architecture and team leadership with a tinkerer’s fluency in schematics, PCB layout, and firmware—comfortably moving from silicon-level concerns to production software. Notably, he has a track record of making build and driver-level changes that enable real hardware features rather than just application-layer integrations.

Role in this project:
Embedded Systems Engineer / IoT Developer
Embedded Systems Engineer / IoT DeveloperContributions:127 commits, 75 PRs, 56 pushes in 4 years 11 months
Contributions summary:Charles's contributions focus on adding features and making modifications to the `hal_pru_generic` driver for the `machinekit/machinekit` repository, particularly within the `src/hal/drivers/hal_pru_generic` directory. This work included adding a step invert option to the pru_generic driver and implementing PRU encoder support. These changes indicate the user is working with low-level control of hardware, likely for CNC machines.

omap image builder
Role in this project:DevOps & Embedded Systems Engineer
DevOps & Embedded Systems EngineerContributions:93 commits, 10 PRs, 6 comments in 3 years 6 months
Contributions summary:Charles primarily focused on building and configuring the image for the `omap-image-builder` repository, which involves building images for embedded systems. They introduced support for custom releases and configuration files, allowing for greater flexibility in image creation. The contributions involved modifying build scripts, particularly `build_image.sh` and `releases.sh`, to enable compression and the deployment of images. These changes facilitated local compression and directory management for the release process, and the user also updated boot configurations by disabling specific hardware components.
