Can't get old iMON VFD to work - chrisk2305 - 2018-01-07

Hi Guys,Hope you can assist me in getting my old iMon VFD to work. I am using LE 8.1.2 atm and the Display is picked up: 
Code:
LibreELEC:~ # dmesg | grep imon
[ 18.122342] imon 2-1.5:1.0: Unknown 0xffdc device, defaulting to VFD and iMON IR
[ 18.162307] Registered IR keymap rc-imon-pad
[ 18.209055] imon 2-1.5:1.0: iMON device (15c2:ffdc, intf0) on usb<2:3> initialized
[ 18.209079] usbcore: registered new interface driver imon

I installed LCDProc and XBMC LCDProc and tried the driver "imon" as wall as "imon-lcd" but none of them work. I also get a lot quite of lot of errors. E.g.: 
Code:
[ 21.962252] Call Trace:

[ 21.972206] imon:vfd_write: send packet #0 failed
[ 245.208341] INFO: task LCDd:823 blocked for more than 120 seconds.

I also change the protocol to "0" which should be the right one for my type of vfd: 15c2:ffdc (in LCDd.conf)


Any idea what I am doing wrong? Thanks in advance! Chris

Please move this thread if this wrong subforum, thanks!
