SPI LCD & GPIO 12,13,14,15

[nradina]

Hi all,

I'm trying to add an SPI LCD screen (with touch) to a project Im developing with this amazing AudioTools/AudioKit library.

I've reviewed the "GPIO-Overview-by-Selected-Board" link and other resources here.

I've also come across a great video from Marcel about some hardware changes that may need to be made to enable SPI properly for a display.

I'm using the number 5 ai_thinker (ES8388) Audiokit board.

It seems there are the proper # and specific GPIO's available to take advantage of the SPI bus.
I think the JTAG header contains GPIO_12,13,14,15.

Yet I'm unsure how the JTAG header is configured with the dip-switches to allow access to those GPIO pins.

Here is my breakdown of my proposed pin assignments.

SOLVED!

I spent some time today with a meter to track down what pins go where and how the dip-switches influence the path,
These are efforts to get a SPI TOUCH screen to work with the AudioKit and Bodmer's excellent TFT_eSPI library
My configuration with the dip-switches are: 0,0,0,1,1

The JTAG header presents ESP32 pins as such (left to right):
15,13,12,14.

Big thanks to this post which helped me sort out the JTAG header.
Thanks to this video by Marcel, I did the following:
I did unsolder the 0R resistors at R66,67,68,69,,70
And bridge pads R60,61,62,63,64.

In order to use the tact switches/buttons, I'll be adding 1.8K resistors at R55,56,57,58,59 .

I hope this helps others trying to get the Ai AudioKit board to work with a SPI display!

The pinout I chose and updated the TFT_eSPI "User_Select_Setup file" is:

Thanks a lot to you nradina to spare your knowledge!!

i noticed your tft setup spares pins with the sdcard of the audiokit,so i wired CS->22 and DC->21
and now i have TFT & SDcard working together and the SD player works too and send music to the headphones.
I have the ac101 version (6 in the settings) and does not give any sound to the HP,only to headphones.
I will make testings with touch buttons of the TFT, to override the hardware buttons of the audiokit cause
i don't need them anymore. i keeped the 01100 configuration of the multi-switch.
Thanks of course to pshatzmann for his library :)
