I'm debugging a CircuitPython issue in which we see input pins stuck at slightly above 2V, even without all the conditions described in the RP2350-E9 erratum. I reproduced the problem...
I was attempting to read the process used by the RP2350 bootrom and I came to the conclusion it does nothing. I noticed the documentation makes a different conclusion. Section...
According to "Figure 18. core power domains" in the RP2350 datasheet, the XIP Cache SRAM is comprised of "(2 instances of 16 kB)".  Section 3.3 of the datasheet, however,...
Hi All, I've just run through the SDK Getting started guide using a Pico 2 and SDK 2.0 under visual studio code as mentioned in the getting started guide. When...
I am referencing [The Getting Started Guide](https://datasheets.raspberrypi.com/pico/getting-started-with-pico.pdf) as of 23-Aug-2024. The document is clear on how to use the command line to change `PICO_BOARD`, but I found no instruction on...
...for sale at this moment. I guess it should be excluded from datasheets recomendations on how to get familiar with USB.
In the chapter 3.2 Getting Started with pio on page 46 last lines. There is the following function described: ``` sm_config_set_out_shift(&c, false, true, rgbw ? 32 : 24); False for...
Pg.907: "Autopush must not be enabled when SHIFTCTRL_FJOIN_RX_PUT or SHIFTCTRL_FJOIN_RX_PUTGET is set" should be "Autopush must not be enabled when SHIFTCTRL_FJOIN_RX_PUT or SHIFTCTRL_FJOIN_RX_GET is set"
The documentation doesn't specify if the unused data input bits are zero-filled or bit-repeated from the valid bits. Experimenting I confirmed they are zero-filled; this prevents various otherwise useful configurations...
Between the Schematic and the PCB Layout snippets of the RP2350 Hardware Design Guide, R3 in Figure 3 Is mislabeled in Figure 4 (Labelled R5).   Figure 15 (The...
