Examples

using ch32v003fun (not as many as using the HAL)

Building

Single file header/source

ch32v003fun.[h,c] -- single self-contained source file and header file for compling apps for the ch32v003.

Standalone libgcc

So unusual risc-v build chains can be used, there is an extra copy of libgcc located in misc/libgcc.a.

Programming

Minichlink

"minichlink" programmer/debugger software which can use

• The WCH CH-Link with libusb, for cross-platform use
• An STM32F042 Programmer, the NHC-Link042
• An ESP32S2 Programmer, the esp32s2-funprog
• The official WCH Link-E Programmer.

Demo bootloader

In Progress:

• Other programmer support (ESP32-S2 works, currently)
• OpenOCD-compatible build for minichlink.
• Full-chip-write for faster flash.
• Support for NHC-Link042
• More demos!
