Hello everyone. I am writing to you because I am trying to capture a thermal image (frame of temperature values) using a Lepton 2.5 thermal camera with Break Out board 2.0 connected to a Nucleo U5A5ZJ-Q board. First I connected the following pins of the Break Out board 2.0 to the Nucleo board, as shown in the table below.
I checked the communication of the I2C on the oscilloscope and it seems good. Anyway I read 0 as the temperature of the case of the Lepton Thermal camera and I have never received the VSYNC signal from the Lepton Thermal camera to read the thermal frame on the SPI.
I tried to put software pull-up and to remove them on the I2C, but the situation remains the same.
Then I noted that about each minute the Lepton thermal camera shutter close and open for a while.
Do you have any idea how I can solve this problem?
Thank you very much for the support!
