  Hi, Maybe flipping the sensor image will fix this: sensor.set_vflip(1) This was the solution for my problem with april tags and QR-Codes.

  @jessevl its no different than plugging in the USB cable to charge the stickC. there should not be any concern.

  @os88 attention the back site, you can see the reserved hole, you can open it, and then pass the Grove cable.

  @volatus I2C # SPI You forgot to use #include <SPI.h> in your arduino code. So the code compiled for I2C interface. Beware using the wrong pins for external SPI deviceon your M5Stack. You may brick your display. Interfacing to an external a SPI peripheral device you should use pins which are not in conflict with the pins used for M5Stack internals, as I already wrote in my comments on SPI Interfacing a few days ago: http://community.m5stack.com/topic/1845/micropython-spi/8 You should keep it as they are saying on my spec sheet for the Heltec ESP32 LoRa board: "Pins used by on board OLED or LoRA must not be used for other purpose unless you know what you are doing ! Accordingly, on the M5Stack you should only use the pins marked in blue.

  @crami25 Thanks for the comprehensive reply. It really helps to deepen my understanding. As you pointed out, I always check the M5 Unit's schematic first to assure the protective resistors when I connect the Units to an ESP developing board.
