I´m trying to build a player for my 2 years old son. I found some ideas
like "jukebox 4 kids" on the web, but I´d like to integrate it in my
Squeezebox setup.
I bought a pi zero w and a hiffiberry for pi zero, i used picoreplayer
(version 4.1.0) and used a python script that should read the rfid t

Always check the input before doing something !!
Code:
if len(RFID_input) == 10:
Thanks for your reply and suggestion. I was thinking about this, but
this would mean that you´d need to hold the tag about 5 times in front
of the Reader before you will receive the correct tag.
So I was wondering if it has to do with the drivers of Tiny core Linux
or with the powermanagement, and
I would say its not a driver but a latency issue.
Did you tried tinycore already?
Thats the base of picore but doesnt run in ram.

thanks for your reply. I was not able to set up wifi on tiny core but
will try again and see if this will work better.
I wonder if it is a problem about the latency if it will be possible to
stay with picoreplayer and solve this issue or if this is due to the
system design and cannot be fixed.

You didnt need wifi to check the "keyboard" sends 10 digits

yes but I need Wifi or a monitor output (on a pi zero) to be able to
login etc as I have not monitoradapter, I need wifi.
Anyway I just tried with tinycore 9.0.3 on an older raspberry with lan
port and it reads like the raspian image:
Code:
login as: tc
tc@192.168.10.
so I now double checked again with piCoreplayer 4.0.1 on the old
raspberry and the result was okay, the first two readingy where
incomplete the others where complete. So I got back to the piZero and
here I see the problem again:
Code:
tc@piCorePlayer:~$ sudo cat /dev/tty

The Zero is tricky and it only gots a single usb Port.
Is the "old" RPI a V3?

Simple first thing to try with "flaky" USB devices is to try with a USB
hub - in case power or incompatibility of some sort.
According to website which gathers USB ids ID 16c0:27db - it is a "Free
USB HID/PID pair for use with V-USB projects" and should be driven by
an open source driver. V-USB
sorry for bombing my own thread, but after just using a diffrent piZero
(with the same sd card) this one does not seam to have the problem

After you plugin the rfid device - are there then two "keyboards"
plugged into the Pi or are you accessing the pi over network ?

I´m accesing through network (wireless) and there is only one keybord
(the rfid Reader) connected and Nothing else
About the other suggestions from your side, I will check tomorrow but
allready thank you for your efforts

Very odd lsusb did not give verbose info about USB such as

thx.
than i would start with something like this instead of closing tty -
that seems the problematic part
Code:
hi
i tried with python3 (by putting #!/usr/bin/env python3 in the first
line) but get
Code:
File "test.py", line 17, in
main()
File "test.py", line 9, in main
RFID_input = input()
File "", line 1
01109679
^
SyntaxError: invalid token
-
suceeded after deciding to give up...
i used the code from the github project, reduced it to what i needed and
was able to install evdev on the piCorePlayer image. Now it reads 100%
of the tags correct with this code:
Code:
from socket import socket
from evdev import I
21 matches
