    apart from that (High heat on the voltage regulator), is there anyone that manage to use the display off command?

    when i used the command, i managed to power off the dipslay. But i couldnt powered up again. It seems it doesnt work.

    As from my measurements, the current of the circuits is 1,3 A. This is too much.

    Only the display gets about 0,7A to 0,8A when you use all the pixels in white color. (very bad).

    That's why it is needed to use the power off comands.

    Regards,

    Maybe there is a sleep command?

    Power off means that it may not communicate again, as it is ... off!

    hi Ioannis,

    there is a sleep command but i think it does not turn the display backlight off.

    I will try it and keep you updated.

    what i have noticed is:

    when you use the sleep mode ($5A) it turns off only display like a clear lcd command.

    when you use the display off command $59 it completes shut down the display.

    i managed to turn on the diplsay again. I'm happy but still the program has a lot of bugs, because i dont know if this procedure is safe for the display.

    what i mean:

    first i initialize the display by the command $55 which is also the autobound.
    this has to be paused for approximatelly 200ms or more. I have put it on 1000 ms.

    Then after all i use commands to display pictures.

    The first picture is the logo.

    In order to shut down the display, i use the $59,$00 inside the gotosub logo, and then i turn off the display.

    Then when i use a tag to RFID reader, inside the tag_found command i use the command $59,01 to turn on the display.

    i will upload a video so you understand what i do. Do not panic for my bugs.....i know there are a lot but have in mind that i'm not a programmer and i dont know how to use the interrupt command at all.

    thanks for understanding.

    based on the above video i would like a little bit of help?

    as you see the first picture (the blue "star", actually it is a symbol,but anyway), it dissapear from the screen and then the screen goes off.

    I would like to do something but i dont really know how to use inrerrupt.

    I want to display this symbol every 5 seconds, and when the tag pass from the reader, to display the picture that corresponds to the tag.

    I think this can be done using interrupt but i have never used it and i have read some programs, but cannot understant.

    do you have any simple example using an led flashing and a button that interrupts the process?

    thanks for any help.
