ESP32 with Lepton

Postby ZePedro80 » Thu Jul 29, 2021 4:08 pm

Hello everyone!
In my project I am using a Lepton FLIR 3.5 coupled in a Lepton FLIR Breakout Board v2.0 connected to a Adafruit ESP32 Feather, but following this tutorial: https://lepton.flir.com/getting-started ... pi-lepton/
However, the only connection that I didn’t use was the VSYNC, because I don’t know which pin in the ESP32 should I connect to it.

Thus, when I print the sensor matrix in the Serial Monitor, the first lines are wrong (0 or 65528, most of the time), but the remaining seem ok (attached image). It seems a syncronization problem, i.e., the sensor is not grabing the first values, but when it grabs the image it saves the remaining values.
Do you think that’s because I didn’t use the VSYNC pin? If so, where should I connect it in my ESP32?

I now can print a full matrix of values, but this matrix is everytime the same one (the values don't change).
However, when I upload the code in Arduino IDE, the matrix changes compared to that of the previous compiling.

Any idea of what it might be?

Hi ZePedro

I'm running into some issues with my own FLIR Lepton 3.5 and ESP 32. Can we connect on call and discuss this? (tried inboxing you but I don't have access)
