@robalstona pin 0 is the clock, not ws, according to the sticker on the back. Don't know if that helps.

@rodberry Unfortunately no as its a limit of the ESP32 D0WDQ6. You maybe able to use bluetooth but that's beyond my skillset .

Are you sure that your computer has connected to the the M5-520 access point using your computers wifi manager? IF you not able to access 192.168.4.1 it means you are not connected to the M5Stack device, you may need to refresh the firmware using the M5Burner program.

@felmue The tip has hit the problem. I have implemented a query of the key A in the callback routine after 1 ms. Only if the key is still pressed the routine is executed. Otherwise nothing is done. Now there are no more key presses from the ghost. Thanks

@felmue Good idea. Thanks

@felmue Yes thank you. I never realised that in one of my folder names I had used a white space (maybe I really need reading glasses). Now I am struggling to get my AWS blink setup and running. Will come back later with a detailed description of my challenge ;-)

@felmue Thanks for the pointer !

@felmue Thank you, I've learn a lot from it

@tobias-h said in UHF RFID Unit (JRD-4035) on Arduino Uno: E.g. what board to select in the board manager ? In the Arduino IDE select: Tools - Board - Arduino AVR Boards - Arduino Uno. May I suggest you first get more familiar with the Arduino IDE, your Arduino Uno board and some simpler sketch examples for the Arduino Uno? Then maybe do some experiments with the serial connection (which is needed to talk to the UHF RFID Unit)? Alternatively you can always get an M5Stack device for which the example has been written. Thanks Felix
