HAL for the CH58x RISC-V BLE microcotrollers from WCH.
This crate is under random and active development. DO NOT USE in production.
This should be the reference hal implementation for CH57x, CH58x, CH59x.
- Basic: clock init, delay, interrupt, etc.
- Dedicated runtime: interrupt table, hardware stack push, highcode support, critical section implementation
- embassy support
- time driver with SysTick, defaults to 32KHz tick
- about 7k flash rom overhead
- GPIO, with async support
- UART, basic blocking tx, rx
- RTC, with datetime support
- SysTick delay (conflicts with embassy time driver)
- I2C
- ADC, with Temperature sensor, VBAT sensor
- SPI
- libISP ROM functions
- Basic BLE library support
