Adafruit LCD shield - blinking section of display

Other Hardware Displays
1

Hello!

I've been playing around with Adafruit's RGB LCD shield. I'm trying to get two "sections" to blink.. Basically I have "12:01" displayed on the screen. I can change the hours section of that (12) by using the up/down buttons. What I want is for those two digits to blink when I hit the "Select" button. I tried using blink(), but I get an error if I try to have it blink at a certain place.. i.e. blink(8,0).

Does anyone have any suggestion on how to do this? I've Googled around for a while and can't find anyone that has done this..

Thanks!

post your code .... so we can see what it does (or not)

please use CTRL-T for proper indentation
please use code tags -> # button above smileys

I don't think this is possible with any character mode LCD (any HD44780U based LCD). You can get the cursor or a single character to blink but not multiple characters.

clearing and rewriting the chars on their position very often ?

That should do it. I was thinking along the lines of inherent controller commands.

I just remembered threads of people who have "blinking displays" and how to get rid of them,

a bug can be a feature :wink:
