Damien George	a707fe50b0	rp2/machine_i2c: Use soft I2C only for len=0, and increase timeout. The RP2040 I2C hardware can do writes of length 1 and 2, just not of length 0. So only use software I2C for writes of length 0, to improve performance. Also increase the software I2C timeout for zero-length writes to accommodate the behaviour of a wider range of I2C devices. Fixes issue #8167. Signed-off-by: Damien George <damien@micropython.org>	2022-01-21 15:10:29 +11:00

Damien George	469345e728	rp2: Add new port to Raspberry Pi RP2 microcontroller. This commit adds a new port "rp2" which targets the new Raspberry Pi RP2040 microcontroller. The build system uses pure cmake (with a small Makefile wrapper for convenience). The USB driver is TinyUSB, and there is a machine module with most of the standard classes implemented. Some examples are provided in the examples/rp2/ directory. Work done in collaboration with Graham Sanderson. Signed-off-by: Damien George <damien@micropython.org>	2021-01-30 00:42:29 +11:00
