openmano-mpy/examples/rp2, branch master MicroPython source and hardware configuration for OpenMano rp2/rp2_pio: Add fifo_join support for PIO. 2021-04-16T14:45:38+00:00 Tim Radvan 2021-04-02T18:35:18+00:00 f842a40df4d26bd74b92a3903096fc6b1709222d The PIO state machines on the RP2040 have 4 word deep TX and RX FIFOs. If you only need one direction, you can "merge" them into either a single 8 word deep TX or RX FIFO. We simply add constants to the PIO object, and set the appropriate bits in `shiftctrl`. Resolves #6854. Signed-off-by: Tim Radvan <tim@tjvr.org>

examples/rp2: Add pio_uart_rx.py example. 2021-02-02T00:33:51+00:00 Tim Radvan 2021-02-01T20:07:19+00:00 3ea05e499d52beaecf4c9c54a67510ac031fe27b This was adapted from the `pio/uart_rx` example from the `pico-examples` repository: https://github.com/raspberrypi/pico-examples/blob/master/pio/uart_rx/uart_rx.pio It demonstrates the `jmp_pin` feature in action.

rp2: Add new port to Raspberry Pi RP2 microcontroller. 2021-01-29T13:42:29+00:00 Damien George 2021-01-20T13:34:08+00:00 469345e7285128739e2934e7934e107ffda79fc1 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>
