CH32V003...fun! with CNLohr
CNLohr joins Chris Gammell to discuss the CH32V003, a low-cost RISC-V microcontroller, and his open-source CH32V003fun library. He explains how he implemented a software-only USB stack and used the chip to control a Nixie tube display, demonstrating that complex functions like power regulation and communication can be handled in bare-metal code. The conversation highlights the benefits of avoiding heavy abstraction layers like FreeRTOS for simple tasks and the importance of understanding assembly and datasheets.
