Crate rp235x_hal

Expand description

HAL for the Raspberry Pi RP235x microcontrollers

This is an implementation of the embedded-hal traits for the RP235x microcontrollers

NOTE This HAL is still under active development. This API will remain volatile until 1.0.0

§Crate features

critical-section-impl - critical section that is safe for multicore use
defmt - Implement defmt::Format for several types.
embedded_hal_1 - Support alpha release of embedded-hal
rom-func-cache - Memoize(cache) ROM function pointers on first use to improve performance
rt - Minimal startup / runtime for Cortex-M microcontrollers
rtic-monotonic - Implement rtic_monotonic::Monotonic based on the RP2350 timer peripheral
i2c-write-iter - Implement i2c_write_iter traits for I2C<_, _, Controller>.
binary-info - Include a static variable containing picotool compatible binary info.
