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.

Personally I wouldn't share it with a display, although a SD card might be ok. I haven't tried sharing it with a display because that channel is pretty busy.

You can't share them. It must have a dedicated SPI channel

You can't use the same SPI channel for the display and the VS1053 and the display has to use SYSTEM spi as you can't specify the SPI pins for that option.

I've rearranged the pins a bit to make it fit.

e.g.

'use SPI1 as the SYSTEM SPI. This can be shared with the SD card.
OPTION SYSTEM SPI GP18, GP19, GP16
OPTION LCDPANEL ILI9341, LANDSCAPE, GP14, GP15, GP13, GP20
OPTION TOUCH GP5, GP7
OPTION SDCARD GP4
'SPI1 has been used, now we have to use SPI2
OPTION AUDIO VS1053 GP10, GP11, GP12, GP0, GP1, GP2, GP3
