Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Hello,
On my Waveshare Touch 3.5" screen I have replaced the Pico with the PicoW with v5.07.07a1. I have restored the options I had before and added WIFI:

OPTION SYSTEM SPI GP10,GP11,GP12
OPTION SYSTEM I2C GP0,GP1
OPTION AUTORUN 1
OPTION COLOURCODE ON
OPTION DISPLAY 32, 132
OPTION LCDPANEL ILI9488W,RLANDSCAPE,GP8,GP15,GP9
OPTION TOUCH GP16,GP17
OPTION WIFI xxxxxx, yyyyyyyy
OPTION SDCARD GP22

The time set by WEB NTP is ok, but now I can't read the SD card, files "B:/" error "SDCard not ..". I put back the previous Pico and it works.

Is there a problem with GP22?

Thank you,

Gerardo Rivero,
San Fernando, Cádiz, Spain

Not according to the Pico-W Datasheet. It appears to be the same as it is on the normal Pico. They haven't said that they've used it for anything else. I can't see any difference on the schematic either.

Hello,

I installed v5.07.06 on the same hardware (PicoW on Waveshare PicoResTouch 3.5") and configured the same options, and now the SD card works perfectly.
There is something in the PicoW or the Web version that affects the SD card.

NB: forgot to mention in the first post GP23, GP24, GP25, GP29 are now completely inaccessible from MMBasic as they are used by the pico_w to communicate with the cyw43. The LED on the pico_w is actually driven by an IO port on the cyw43.

I don't think there should be any problem with GP22 though.
