ch57x-pac

Peripheral Access Crate (PAC) for WCH CH57x RISC-V BLE microcontrollers.

This crate is generated using svd2rust and provides register-level access to CH57x peripherals.

Scope

• no_std PAC for CH57x-family register blocks
• Interrupt definitions and vector table support via rt feature
• Optional critical-section integration for embedded Rust ecosystem crates

Cargo

[dependencies]
ch57x-pac = "0.1.3"

Features

• rt (default): exports interrupt symbols/vector table glue expected by runtime crates
• critical-section: enables critical-section support

Minimal Usage

let p = ch57x_pac::Peripherals::take().unwrap();
p.sys.r8_clk_sys_cfg().modify(|_, w| unsafe { w.bits(0) });

docs.rs Notes

docs.rs builds with:

• target: riscv32imac-unknown-none-elf
• features: rt, critical-section

CI/CD

• CI runs cargo check and cargo doc on every push and pull request.
• Publish workflow is configured to publish from version tags (or manual dispatch). The publish job requires repository secret CRATES_IO_TOKEN.
