    Is there any way I can make the displayed text blink?

    I am using PIC16f887

    Thanks

    One way, if the LCD driver doesn't support flashing tyext, is to simply display the text, wait a short time (1/2 sec ?), overwrite the text with blanks, wait a short time (1/2 sec ?) and repeat.

    I am using Assembly language

    Its a LUMEX LCD

    LCM-S01602DSF/A

    Still not figured out the blinking text


    I have configured a port such that as soon as the port bit is set I display a number on the LCD

    I have displayed the number correctly

    I need to make that number blinking

    Part of the relevant code is as follows:

    movlw 0x8A
    movwf PORTD
    call SND_CMD //SND_CMD is writing command to LCD

    movf count304,0
    movwf PORTD
    call SND_DTA //SND_DTA is writing data to LCD

    It works fine

    Just that somehow I need to make that counter value blink

    I tried using the control codes 0x08 and 0x0C but to no effect

    If anyone has an idea please let me know

    Thanks ​
