An open source development environment (tooling, headers, examples) for the CH32x035. All the examples are taken from openwch/ch32x035
These examples uses the customised MRS_Toolchain gcc compiler which supports customized hardware stacking function,
__attribute__((interrupt("WCH-Interrupt-fast"))).
This statement tells GCC to perform a hardware push operation.
cd examples/gpio
make
make flash
The elf can be flashed to the CH32X035 using wchisp. (Enter the CH32X035 bootloader by holding down BOOT when connecting it using USB).
The SDK for CH32X035 from the openwch EVT is vendored under sdk/. (Encoding has been changed from gbk to utf-8).
