Just a wild guess, but IF the sensor uses an "AS3935 Franklin Lightning Sensor IC" by AMS, the datasheet (e.g. https://www.digikey.de/htmldatasheets/production/1124289/0/0/1/as3935.html) might provide some insights about the kind of data...

I would like to bet on what kind of IC U3 is... And we have nice little labelled test points (I²C interface) on the PCB! There shines a little light...

And there is a serial interface (RX, TX), too! Maybe it has something to tell you, too!

Hello, I am encountering the same problem as @Ziesie1. I am trying to use the same display with the [WaveShare e-Paper ESP32 Driver Board](https://www.waveshare.com/e-paper-esp32-driver-board.htm).

I found the following hint in the FAQ: [Question:Why is the BUSY pin always busy?](https://www.waveshare.com/wiki/7.5inch_e-Paper_HAT_(B)_Manual#accordion13), but the answer does not really help me to understand the problem.

Another weird thing: normally, the ESP32's HSPI interface is wired as follows (see https://github.com/espressif/arduino-esp32/blob/master/libraries/SPI/examples/SPI_Multiple_Buses/SPI_Multiple_Buses.ino): ``` SCLK - GPIO14 MOSI - GPIO13 ``` but on the WaveShare e-Paper ESP32 Driver Board...

And maybe because of this, SPI transfers are implemented by bit-banging in the ESP32 Driver Board examples (see DEV_Config.cpp).

I tried the MicroPython version from https://github.com/tanahy/micropython-waveshare-epaper today - https://github.com/tanahy/micropython-waveshare-epaper/blob/dev/epaper7in5_V2.py to be precise. I tweaked the pin configuration a little bit to adapt to the [WaveShare e-Paper ESP32 Driver Board](https://www.waveshare.com/e-paper-esp32-driver-board.htm)...
