Use shield pin(s) for other fucntion

Other Hardware Displays

Is it possible to use pins that are taken by a shield display for other functions? Specifically, I want to drive an IR LED (which I understand needs a certain type of pin) while using one of these

with one of these

the board has been modified as per the Adafruit / Bodmer instructions for GPIO pins

PS is it possible to not have the eBay 'advertisements' appear when including an eBay link?

Yes, it would be nice if you could avoid the Ebay advertisement e.g. Optional Title when inserting link

The ESP32 board has the SD0-SD3,CMD,CLK pins that you could access.
But seriously, you are always going to use up most pins with a Parallel TFT.

I suggest that you buy a regular Red SPI display. e.g. 128x128, 128x160, 240x320, 320x480
Supported by Bodmer. Gives you lots of spare GPIO pins.
When SPI is used sensibly it does not waste any MCU resources.

Put a little bit of text instead of having links on their own line; e.g.

So it looks like:

Thanks David that's what I suspected though thought I'd ask. It'd be a bit of a waste to use a nice fast parallel display for remote buttons, too.

Thanks sterretje I'll do that, the blown up ads are pretty annoying.
