Store a collection of PC editable macro definitions or music files or picture files on the SDCard and then have the Pico read it on power-up. This Waveshare IPS ST7789 LCD Pico Board 320x240 2.8 inch hardwired the LCD, Touch controller and SDCard to SPI-1 which makes the SDCard usable. But this Waveshare IPS ILI9488 Pico Evaluation Board Touch LCD 480x320 3.5 inch has the SDCard hardwired to SDIO pins which are not in the correct sequence for the current PIO drivers. The RPi SDK example is a wip (https://github.com/raspberrypi/pico-extras/tree/master/src/rp2_common/pico_sd_card)

Sep 2022: There is an implementation for the RP2040 here:

And this could be a solution: https://github.com/carlk3/no-OS-FatFS-SD-SDIO-SPI-RPi-Pico or https://github.com/carlk3/no-OS-FatFS-SD-SPI-RPi-Pico/tree/sdio - D0 to D3 are offset correctly (each D0 + 1) but SDIO-CLK is not at the required D0 - 2 offset.

There is a note that "For SDIO, data lines D0 - D3 must be on consecutive GPIOs, with D0 being the lowest numbered GPIO. Furthermore, the CMD signal must be on GPIO D0 GPIO number - 2, modulo 32. (This can be changed in the PIO code.)"

Similarly at Visrealm it notes: Six GPIOs for signal pins, and, optionally, another for CD (Card Detect). Four pins must be at fixed offsets from D0 (which itself can be anywhere):
CLK_gpio = D0_gpio - 2.
D1_gpio = D0_gpio + 1;
D2_gpio = D0_gpio + 2;
D3_gpio = D0_gpio + 3;

Great that you made this together. We have developed a Music player for people with Dementia based on Rpi's. However, the Rpi 's are difficult toe get. So we want to use the Pico in combinatie with the VS1053. ( wi use the adafruit music maker).
Will build test in next weeks.
Any recommendations?
Thanks

Ps we are a foundation and have an open source approach.

ST7789 LCD Macropad and TFT_eSP V2.5.43 fix: To obtain a working Touch-Macropad for the the Waveshare IPS ST7789 LCD Pico Board 320x240 2.8 inch using Bodmer TFT_eSPI version 2.5.43 replace the file Processors/TFT_eSPI_RP2040.h with the same file from the previous version V2.5.34.

Choosing an LCD Touch Display: Of the 5 different LCD displays tested here, with the firmware as attached below, my favourite is the fast Waveshare 3.5 inch Type C 125MHz LCD display (even though it is not an IPS screen). It is available here.
