Embedded Designs using CH32Vxxx Microcontrollers
IoT Contest Conclusion
Part 1 Part 2 I am delighted to present my final submission for the IoT contest. Throughout this journey, I have worked diligently to develop a reaction trainer prototype rivalling existing commercial solutions such as Blaze Pods. By leveraging the capabilities of the CH32V208W microcontroller, I have designed a custom PCB that incorporates a calibrated […]
IoT Contest: Reaction Trainer Design
See Part 1 for the Contest Overview See Part 3 for the Final Submission As always you find the design files on my GitHub. Designing a sensor that meets the specific requirements of a particular application involves overcoming several hardware challenges. From creating a Printed Circuit Board (PCB) using Computer-Aided Engineering (CAE) software to carefully […]
IoT Contest – Next-Generation Reaction Trainer using RISCV and RT-Thead
See Part 2 for the Hardware Design See Part 3 for the Final Submission I have been following Nanjing Qinheng Microelectronics (WCH) for a while. They have a very interesting line-up of low-cost RISCV microcontrollers with a lot of different connectivity options that rival big shots like ST or NXP. A couple of weeks ago […]
32-bits at $0.10
In the previous year, I conducted research on 8051 processors and stumbled upon WCH during my investigation. I was impressed to find that they offer a wide range of interesting 8051 microcontrollers, which feature host and device USB support and are reasonably priced. Recently, the vendor announced the release of their value-line RISC-V microcontrollers, further […]
