  Issues interfacing MFRC522 (RFID) with M5Stack

  @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.

  I got it work using python serial on the raspberry pi. It's now reading the input from the UnitV and performing functions based on that input. I did need to disable the serial console on the Pi as it was causing issues. I think the UnitV requires the 5v input as its not powering enough with the 3.3v using the GROVE connection.

  Please Help: Has anybody had success with the ESP32CAM on Arduino?

  @lurk_ said in Please Help: Has anybody had success with the ESP32CAM on Arduino?: @marka2 Using the example ESP32CAM in the camera settings CAMERA_MODEL_M5STACK_PSRAM I changed the initialization of the foam #define Y2_GPIO_NUM from 32 to 17 and installed the firmware. It worked for me. Let me know if You do not work and what will be the error. For streaming video memory is enough, facial recognition modules do not work correctly, the reason I think lies in the lack of memory, but I just needed a camera for the project and I do not use these features. I confirm Lurk's comment: by changing Y2_GPIO_NUM from 32 to 17 this allowed the camera to work on my M5STACK ESP32CAM (the one from the picture). Note that now it is included in the CameraWebServer example: https://github.com/espressif/arduino-esp32/blob/master/libraries/ESP32/examples/Camera/CameraWebServer/CameraWebServer.ino I used #define CAMERA_MODEL_TTGO_T_JOURNAL // No PSRAM and it worked first try! Hope that this helps someone!

  Hello. Please tell me if there is a UnitV circuit diagram? Or, by analogy with other modules, a description of which components, to which GPIO are connected. For example, the GROVE connector is connected to gpio xx and yy, the camera is connected to "...", the buttons are "..." and so on.

  @ckuehnel There doesn't look to be any control circuits in the 18650 hat and so you need an external controller fitted to the battery to provide that information.
