openmano-mpy/ports/rp2/modules, 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>

rp2: Import uarray instead of array in rp2 module. 2021-04-07T00:06:18+00:00 Tim Radvan 2021-04-03T11:20:48+00:00 4f53f462ca9dbec45771e06d2d1a84b61e01e61a Some forum users noticed that `sm.exec()` took longer the more was present on the flash filesystem connected to the RP2040. They traced this back to the `array` import inside `asm_pio()`, which is causing MicroPython to scan the filesystem. uarray is a built-in module, so importing it shouldn't require scanning the filesystem. We avoid moving the import to the top-level in order to keep the namespace clean; we don't want to accidentally expose `rp2.array`.

uarray is a built-in module, so importing it shouldn't require scanning the
filesystem.

We avoid moving the import to the top-level in order to keep the namespace

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>
