I build up some kind of RFID-Reader with an Raspberry Pi 3 and an RC522 using this code as a start: https://github.com/mxgxw/MFRC522-python.
Unfortunately I'm not able to get a APDU-Response from my card after sending any APDU-Command.
My current workflow is more or less the ISO 14443-4:
Search for cards
receive ATQA
Perform anticollision and select card
Determine whether card is supporting ISO-14443-4 protocol or not
Send RATS and receive ATS
Perform an PPS-Request [Until here everything is fine and I get responses.]
Send an APDU-Command [btw. command works fine with my smartphone and an APP]

The command is send using the 'toCard' function of the code mentioned above with following structure:
APDU-Command + CRC-Bytes.
e.g. 0x00 [CLA], 0x22 [INS], 0xC1 [P1], 0xA4 [P2], 0x12 [Length], 0x80 [DATA, 0x0A, 0x04, 0x00, 0x7F, 0x00, 0x07, 0x02, 0x02, 0x04, 0x02, 0x02, 0x83, 0x01, 0x02, 0x84, 0x01, 0x0D, CRC1, CRC2
I also tried sending the Command with an additional PCB or in multiple parts (e.g. Header first then body).
I'm not sure if the structure of the APDU-Command is or if I forgot some part of the activation process as of ISO 14443. I'd be glad if anybody can help me.
I have a matrix keypad and a hd44780 lcd connected into raspberry pi.
The below code are in python. It will take 4 digit password from the user, but when the user enter the digit through the keypad, nothing was display on the lcd. I would like when the user enter a digit a * display on the lcd. I can only manage to get the * print in the same place,but not in 4 separate place.

Your code may be not correct. For each output you test all inputs:
for i in range(4):
if GPIO.input(ROW[i]) == 0:
Check if for sure exactly one proper input is active. If not, you have to rewrite it.
Moreover, the number of * should depend on external counter j, not i (my mistake in the comment, sorry):
mylcd.lcd_display_string((j+1) * "*", 2, 0)
After searching for several hours i´m wondering if its possible to simulate a keydown press on the keyboard. For example I want my program to hold the x key down for five seconds so when I run it in notepad it would look like to see something like this: xxxxxxxxxxxxx. I tried around with different pieces of code on the internet, the best thing I could find so far is this:
import ctypes
import time
user32 = ctypes.windll.user32
inputhex = raw_input("Please enter your desired key's code (HEX): ")
keycode = int(inputhex, 16)
time.sleep(1)
#VOID keybd_event(BYTE bVk, BYTE bScan, DWORD dwFlags, PTR dwExtraInfo);
user32.keybd_event(keycode,0,2,0) #is the code for KEYDOWN
time.sleep(5)
#user32.keybd_event(keycode,0,0,0) #is the code for KEYDUP[/code]
The Sendkey module doesn't solve my problem either becuase it only allows you to send a single keypress and not a hold key down event. I know about autoit, used it in the past, but I just really want to know if this is possible with python and how.
P.S. i'm using python for windows

If you're using Python for Windows then there's a very good chance that you have the win32api module, which handles hooking into the API for you...
import win32api
import win32con
win32api.keybd_event(win32con.SHIFT_PRESSED, 0,win32con.KEYEVENTF_EXTENDEDKEY, 0)
Does that help? (p.s. you should install IPython if, at all possible, it's massively helpful for experimenting)
I know that this question is really old, but I found a nice library: PyUserInput.
I am not sure how to download it in windows(I haven't downloaded libraries for windows for a long time). In Linux is easy just download pip(if you haven't):sudo apt-get install pip and then sudo pip install pyuserinput.
And then the code is realy simple:
#imports the library
from pykeyboard import PyKeyboard
#import the sleep function
from time import sleep
#initialize the keyboard simulator
keyboard = PyKeyboard()
#presses the key
keyboard.press_key('x')
#waits five seconds before releasing the key
sleep(5)
#releases the key
keyboard.release_key('x')
You can use pynput library which is easy to use.
from pynput.keyboard import Key, Listener, Controller as keyboard_controller
keyboard = keyboard_controller()
keyboard.type("Please enter your desired key's code (HEX): ")
You can also simulate mouse even with this library.
I've modified the Noctis answer to work with Unicode characters.
