CH32V003 Programming Tutorial

WCH Electronics has released an Ultra Low Cost MCU of just 0.1$ in volumes, CH32V003.

If you are an embedded Engineer, learn about the MCU, the hardware and basic programming. It will be very helpful for your projects.

Low-end products could very well be done with CH32V003, or you can also offload some part of the work to this MCU in a complex project like MCU providing extra IOs or diving OLED or Character Display, and you send data over I2C or UART, just an example.
