  You might be using the wrong key to authenticate to the RFID sectors. See https://stackoverflow.com/questions/56225136/mifare-classic-standard-keys For my Mifare Classic tag, I go lucky with using FFFFFFFFFFFF as key B to access sector 4. Unfortunately they key cannot be changed in the UIFlow block, you have to manually change it in the Python code. For example: label0.setText(str(rfid0.readBlockStr(4, keyB=[0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF])))

  Hi, I just ran some test and the LED doesn't work if the lithium battery in the base is below 3.8 volts. the microprocessor wont start up and so the M5StickC can't communicate.

  Is this problem already solved? It seems to be a mistake in the sample program. Although, the variable 'count' in the function i2c_transmit() should be global, it is interpreted as local. I modified the function i2c_on_transmit() as follows: def i2c_on_transmit (): global count count = count + 1 print ("on_transmit, send:", count) return count Then, it worked well.

  @m5stack I have tried Tag36H11 images for numbers and this makes no difference. UnitV with M5Stack Fire and UIFlow did not decode the images. I did not make any alternation to my UIFlow code. Did you test this software?

  Hi Van If you like to experiment there is a magnetometer BMM150 in M5Core Gray, Fire and M5GO. Also the M5StickC ENV Hat contains the same BMM150. But I guess you already knew that. Cheers Felix

  How about the code for the ST7789 chip (at 135 x 160) as well? I can't figure out how to use the whole screen using M5.lcd
