Re: [AVR-Chat] OT: HD44780 LCD lock-up - busy flag stays set

2007-08-23 by Mark Nowell

Tim et al, Thanks all for lots of useful advice. I've tried various recommendations but haven't fixed the problem. I added a loop counter to the busy flag check to limit the busy checking to max 1.6ms, then just went ahead and sent the instruction regardless of the busy flag. Thi

Mark, Being HD44780 compatible only means that they cloned the command set developed by Hitachi some 20 years ago. In my collection of LCDs (and I have a lot of them), I've only ever seen 1 unit that had real hitachi HD44780 chips (it's really old and required the 8 bit interface

According to the display datasheet it's apparently a "KS0066U or Equivalent", and according to Google, the KS0066U is compatible with the HD44780 apart from some timing differences in the initialisation sequence, where it seems I'm well within spec for both devices. Having said w

Hi Mark, If your program has been working with other HD44780 display drivers, I'd assume some problem with the displays. I haven't seen that they changed anything within that chip. Or does HD44780 compatible mean it actually uses an HD44780? Or something else? Zack On Wed, 22 Aug
