#91505 - LCD problem |
In one of my projects, I am using 20 x 4 character display.
I am directly driving the lcd using the port pins (port2). I am using 4bit interface. The syastem also has some relays. My problem is that, sometimes when relays are made on /off which in turn make solenoid coils on/off, the lcd on front panel start displaying some unwanted characters or even gets blank completely. All other functions work fine. How can I overcome this problem? |
