Help with wiring thermal sensor, microcontroller & display

Post by Gh0stFPV »

Product list:

PiTFT Plus Assembled 320x240 2.8" TFT + Resistive Touchscreen

1000mah battery

Amg8833 Ir Thermal Camera Breakout 8X8

Adafruit HUZZAH32 – ESP32 Feather Board

Slide switch


Issue:

I haven't been able to find a descriptive guide on how to put these components all together. I've seen them being used together in tome pictures but I just don't know how to wire these all together. Hoping someone smarter than me can show me how to wire these up. I've tried looking at the schematics and matching them up but I honestly don't know what I'm reading.

I've got a background in wiring fpv drones, but this a whole new level for me.

Thanks in advance!

That collection of parts will give you some challenges. The PiTFT is designed to work with a Raspberry Pi instead of a microcontroller, and you'll want to check the battery's voltage before connecting it to any of the other parts. The microcontroller, AMG8833, and display all want a 3.3V supply.

This tutorial shows how to make an AMG8833 talk to a microcontroller:

https://learn.adafruit.com/adafruit-amg ... era-sensor

The PiTFT's display uses an ILI9341 driver, so the code from this tutorial will work:

https://learn.adafruit.com/adafruit-2-8 ... reakout-v2

but you'll need to use the PiTFT's SPI pins (MOSI, MISO, SCK, CE0, CE1) plus GPIO 25 (D/C for the ILI9341). We also have a library that will let the microcontroller talk to the STMPE610 touchscreen controller:

https://github.com/adafruit/Adafruit_STMPE610

which will need the SPI pins and the PiTFT's GPIO 24 as an interrupt signal.

The PiTFT schematic is here:

and the pinouts for the RasPi live at https://pinout.xyz/pinout/spi
