Problem switching to version 1.0.0 about diozero HOT 6 CLOSED

Hi Christian, sorry about this. I suspect I know what is going on here, could you let me know the output of these commands please:

uname -a
cat -v /proc/device-tree/compatible
grep Revision /proc/cpuinfo
ls -l /dev/gpio*

In the meantime could you please try run with -Ddiozero.gpio.chardev=false and let me know if that helps.

Hi Matt,

thanks for the reply. The diozero.gpio.chardev=false settings solved it.

As for the information you asked for:

chris@web-radio:~$ uname -a
Linux web-radio 5.4.79+ #1373 Mon Nov 23 13:18:15 GMT 2020 armv6l GNU/Linux

chris@web-radio:~$ cat -v /proc/device-tree/compatible
raspberrypi,model-b^@brcm,bcm2835^

chris@web-radio:~$ grep Revision /proc/cpuinfo 
Revision	: 000f

chris@web-radio:~$ ls -l /dev/gpio*
crw-rw---- 1 root gpio 254, 0 Jan  9 23:17 /dev/gpiochip0
crw-rw---- 1 root gpio 246, 0 Jan  9 23:17 /dev/gpiomem

Yes, it's an older PI, Java startup is sloooow, but RFID-Card reading seems to be much faster with MFRC522 using diozero than the Python libs I've tested... (+ I am a Java guy... :-))

Thanks for the library!

I've just released 1.0.1 - hopefully with this release you won't need to run with -Ddiozero.gpio.chardev=false

Thanks! Will start testing right away tomorrow and give you feedback.

Version 1.0.1 works like charm (without -Ddiozero.gpio.chardev=false).

Thanks for the quick fix and new release!

You're very welcome.
