Display something other then the time?

[whoman321]

Hello!

Would it be possible to display numbers on the time display through userspace?

I see that in Demo mode the OpenVFDService does rotate through a number of different character output on the HH:MM, however I can't really see how I could modify that to achieve my goal.

I'm using a python script for my box, and I'd like to send something other then time, for example, the cpu temp to HH and cpu usage to MM.

I can get those values in my python script, but I'm not sure how to send them to the HH:MM display

Ideally I'd like to populate those two values (HH and MM) separately.

Since I'm using python, I can easily enable and disable the other leds (wifi, eth, etc) by executing the usual command line command:

echo wifi > /sys/class/leds/openvfd/led_on

Is there a way I can send the temperature in a similar way through a command line command, or if not, directly through python?

If you could point me in the right direction, I'd be super appreciative.

Thanks so much for all hard work.

Solved this by hacking OpenVFDService to feed 2 command line variables to time_date.hours and time_date.minutes.

Hello all,
I managed to let temperature show up on the disokay. But I wasn't able to show degree symbol (°C) on time_date.minutes. Could you please guide me with that?
Thank you!

Ascii value 176 should print degree sign.

Thank you for replying. Actually, I did try to add ascii value to time_date.minutes like this:
1)
char degree = 176;
time_date.minutes = degree;
--> This will print value 76 to minutes LED.
2)
char sign = 'C';
time_date.minutes = sign;
--> This will print value 67 to minutes LED.

Can you tell me what I'm doing wrong?
