Character LCDs / Re: NHD-0420DZ-FL-YBW Cursor On-Off problem
« on: January 07, 2016, 02:16:27 PM »
Actually I have resolved this problem myself. I am using one port to output the 4 bit data and chip enable, when I set the data value I was inadvertently setting the chip enable low at the same time. Depending on timing conditions correct or unpredictable results occurred. I have modified my code to OR a 1 onto the chip enable line when I set the data so that it stays high until ready to clock the data in. No more unpredictable results.

Character LCDs / NHD-0420DZ-FL-YBW Cursor On-Off problem

I am using a NHD-0420DZ-FL-YBW is 4 bit mode. When I try to turn the cursor off by issuing command 0b00001100 it clears the display and homes the cursor but leaves the cursor On and Blinking. How can I leave the display memory intact but turn the blinking and cursor Off?
