I'm building a project with a ESP-32cam module and see that it is possible to connect a TFT display as well.
Is it possible to use TOUCH with this?
(I'm guessing not as GPIO0 is used for the cam module, but it's worth an ask )

Re: Touch with AnnexCam
Hi Andy,
are there enough free pins for connecting a display???
I even had a problem to find two pins for connecting two servos to an ESP32-CAM

Re: Touch with AnnexCam
Hi Peter,
The help file gives the impression the TFT display is supported and the device config page gives an option of 'TFT and SD on SPI2'.
I haven't looked at the circuit schematic in detail but I assume there must be some pin sharing going on and still allowing both to operate normally, if they can indeed be used simultanously.

Re: Touch with AnnexCam
Are you sure about the support table in the helpfile?
I did read the red crosses just the other way

Here is where I kick myself soumndly in the behind
You are absolutely right; The red crosses are the enabled features, not the other way around.
(I did think there were some strange choices in there )
And there goes my neopixel plan too.

Re: Touch with AnnexCam
I used io3 (RX) and io12 for my two servos.
If you want to solder ... IO33 is connected to the red on-board-LED only

Re: Touch with AnnexCam
I'm looking to make a time-lapse camera from the module and was hoping to use a neopixel ring instead of the onboard LED for illumination.
No matter, I'll use a couple more COB LEDs and drive them (suitably buffered) with one of the spare I/O lines you mention.
I was hoping to make this a combined unit with the TFT but I suppose now is as good a time as any to start getting to grips with HTML (which I've been resisting for a long time) and implement it on a browser interface.

Re: Touch with AnnexCam
I did some playing around with timelapes.
My webinterface allows to save photos at the local SD-card by pressing a button in the browser - easy to change that to a regularly storing.
But in the end I used the telegram_bot for on-demand-storing the photos to my telegram account. And then - on the iPhone - I used an APP to create animated-GIFs
if you send me a personal email I can give you access to my two CAMs currently connected to a Telegram_Bot
