Building Firmware and Hardware for Trade Shows with Mike Szczys
Mike Szczys, formerly of Hackaday and now at Golioth, discusses building firmware and hardware for trade shows like Embedded World with his coworker Chris Gammell. They detail the challenges of integrating E-Ink displays using Zephyr RTOS and MicroPython on an RP2040-based faceplate, highlighting the steep learning curve of Zephyr's device tree and manifest system. The conversation covers the benefits of Zephyr's centralized ecosystem compared to FreeRTOS, the use of built-in debugging shells, and the technical hurdles of I2C peripheral programming on the Raspberry Pi Pico.
