Instructions

• Time by SysTick shows how to schedule your program flow using the SysTick counter
• Fast debug printf explains how the SWIO debug interface can be used to "printf" (only with some programmers)

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!
