RP2040

Raspberry Pi Pico and Pico W driver. More...

Detailed Description

This driver is known to work with the following MCUs:

• Raspberry Pi Pico W

Note

While the RP2040's datasheet claims it supports multi-master configurations by implementing bus arbitration, it does not natively support a mode where it is configured as a (multi-)master with a slave address, such that it can be addressed by other multi-masters.

This driver includes a workaround that uses both I²C peripherals on the RP2040. To use this driver, make sure you initialize both I²C peripherals, and connect their respective SDA and SCL pins to the same I²C bus.

Usage

• Link the pbdrv-mod library with your main executable
• Call the pb_setup() function (from <pb-mod.h>) during setup

Note

This driver is automatically enabled if the variable PICO_PLATFORM is equal to "rp2040" in your CMakeLists.txt (it is by default when using the pico-sdk CMake library).

This driver automatically includes the stdlib extension as the pico-sdk implements the C standard library.

Functions
void	pb_setup ()
	Puzzle bus driver setup.

Function Documentation

pb_setup()

void pb_setup

(

)

This function must be called from a setup/init function to initialize the I²C peripherals used by this driver.
