RC522

Hi,

I tried integrating RC522. I see below issue..

Try to open device /dev/spidev0.0
Device opened
Device Number:3
SPI mode [OK]
SPI word bits[OK]
SPI max speed[OK]
Failed to initialize: Success

On debugging I see read register failed. Does that mean RC522 not working ?.

ADCDevice error Joystick

When I try the Joystick program, raspberry send this output

Will not read RFID tags

I am using a raspberry pi 4 model b running the latest version of raspbian (2020-02-13). I followed this tutorial on how to use the rc522 RFID scanner with a raspberry pi: https://pimylifeup.com/raspberry-pi-rfid-rc522/ / https://www.youtube.com/watch?v=evRuZRxvPFI&t=172s . After I had ran Write.py it would not recognize the RFID tag. I’m a beginner so I don’t understand most of this. The tags I were using came with the scanner. All my wires are set up correctly and are soldered properly. When I place the tag on it it will not write “Written” in the terminal. Any solutions? Here is a photo of my setup:

MFRC522 hexadecimal input

Hi
I am working on a project and want to enter Hexadecimal values for input data rather than ACII.
I am really new to RPi and also to Python. I dont know where to ask and how to get help.
Can someone help me with this

Code examples in rust

Thank you for this fantastic rpi learning product.
While going through each chapter, I decided to learn the rust language for embedded programming at the same time. I started to port the sample code from each chapter into rust. It's not yet accomplished for all the chapters but I'd like to know if there is any interest to merge it into the official repo. The wip code can be found at https://github.com/onixie/Freenove_RFID_Starter_Kit_for_Raspberry_Pi/tree/master/Code/Rust_Code

Welcome any comments and feedback.

Chapter 2: Some hardware is redundant

In chapter 2 about controlling the LED with a button.
The python and C code put the buttonPin into pull up mode which leads to the usage of the internal resistors of the RasberryPi.
Therefore, some of the shown components in the diagram are not required (tested by myself and works):

The GPIO18 port can be connected directly to GND with only the button in between.

See https://github.com/raspberrypilearning/physical-computing-guide/blob/master/pull_up_down.md for more information

Can you please tell me what below error means? I'm simply trying to run Read.py
