Touch with AnnexCam

Post by AndyGadget »

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 :D )

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

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.

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 :D
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 :lol: )

And there goes my neopixel plan too.

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

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.

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
