Add SparkFun ThingPlus RP2350 #2038

LGTM, but I guess this might need a line to satisfy the upcoming #2034 ? ping @will-v-pi |
Yeah, that’d be good, so I don’t have to rebase #2034 on top of this to add it |
|
Done! |

I'm just looking at this as part of the update for CYW43 support in arduino-pico on the RP2350 boards, so maybe I'm missing something, but are data_in, data_out, and host_wake all on pin 24?

Yep! Theoretically any GPIO pins can be used (see here: #1938 (comment)), but Raspberry Pi managed to cleverly connect all 3 pins of the radio to a single GPIO pin on the host processor. For reference, see the Pico W datasheet (schematic on page 23). This board uses the same connections with the same resistors to avoid contention.

https://github.com/raspberrypi/pico-sdk/blob/develop/src/rp2_common/pico_cyw43_driver/cyw43_bus_pio_spi.c is where the software-side magic works.

Nice, thanks for the explanation!

Hi there! Just curious to get an idea of what timeline to expect. Will this be able to make it into the v2.1.0 release? And is there an ETA of when that will release come out? Thanks! |
Upcoming board from us!
