Two Readers (CS0 and CS1) not working in one program about pi-rc522 HOT 7 OPEN

Solved.
The trick was:
rdr2 = RFID.RFID("/dev/spidev0.0",pin_ce=24)
rdr1 = RFID.RFID("/dev/spidev0.1",pin_ce=26)

Bye,
Thomas
`
import RFID
import signal
import time

run = True

rdr2 = RFID.RFID("/dev/spidev0.0",pin_ce=24)
rdr1 = RFID.RFID("/dev/spidev0.1",pin_ce=26)

def end_read(signal,frame):
global run
print ("\nCtrl+C captured, ending read.")
run = False
rdr1.cleanup()
rdr2.cleanup()

signal.signal(signal.SIGINT, end_read)

print ("\nStarting")
while run:
print("\n******")
(error, data) = rdr1.request()
if not error:
print ("\nDetected: " + format(data, "02x"))

    (error, uid) = rdr1.anticoll()
    if not error:
      print ("Card read UID IN : "+str(uid[0])+","+str(uid[1])+","+str(uid[2])+","+str(uid[3]))
(error, data) = rdr2.request()
if not error:
    print ("\nDetected: " + format(data, "02x"))
    (error, uid) = rdr2.anticoll()
    if not error:
      print ("Card read UID OUT : "+str(uid[0])+","+str(uid[1])+","+str(uid[2])+","+str(uid[3]))

@ondryaso I guess this issue can be closed.

You forgot the rst pin.

rdr1 = RFID.RFID(device=0, pin_ce=24, pin_rst=22)
rdr2 = RFID.RFID(device=1, pin_ce=26, pin_rst=18)

edit: is the rst pin required? Can you chain them? I've seen some wiring rst together...
