Oled

[fowardbias]

Has any one used the LCD write commands with a HD44780 "like" controller. Several OLED modules are advertised this way. How much "like" is my question? Did anyone find that the similarities were minor or did it require a complete rewrite? I hope to move into 3V OLED character displays for projects.

In the past I have used some of the OLED displays BUT, at the time they only had a life expectancy of about 500 to 10000 hours. They were right. I did however have no problem using the PBP commands to write to them.

Good point. I found a few with 80,000hr. life expectancy (50% luminosity). OK for me, I'm going for it, cost around $30 US.

Is there any special reason why one should pay 30 bucks for an LCD?

KS0108 controller is very “like” in it’s interface to HD44780. So much “like” that it’s exactly the same.

LCDOUT could certainly be used exclusively to control one, except the actual commands are different.

Dave, was it not you that once posted, maybe a few years back, some graphics code for GLCD?
Are the interfaces any different? I think the particular LCD you used might have been KS0108, and were printing images to it or something like that.

Art, I have used in the past dot matrix LCD's and and dot matrix VFD's for a few different projects.
