Fresh hacks every day
[Debraj] wrote in about his 2-wire serial backpack he developed for a Graphic LCD screen. It’s build on a hunk of protoboard and uses a pair of 595 shift registers to translate incoming serial data to the parallel interface which is used by the LCD screen. It takes more time to push commands this way, but the interface is … Read the rest
This Graphic LCD clock doesn’t have a fancy case, but [Gregory Wright] built in so many great features we think it will serve as inspiration for many projects to come. If he does decide to add a case it will be quite easy as there are no buttons to work around.
Without buttons how can the thing be adjusted? He … Read the rest
I finally set aside some time for one of my own projects. I have been playing around with ARM microcontrollers a lot lately and wanted to try out my GLCD display that uses the KS0108 protocol. It’s 5V but I had heard that some of these displays will work with 3.3V TTL. But the datasheet tells me otherwise. I tried … Read the rest
This hack lets you use a TV in place of a graphic LCD screen. But we like to think of this less as a replacement for a GLCD and more of a simple way to get your information onto a television. A PIC 18F452 acts as a translator between the GLCD parallel inputs and a composite video output. There … Read the rest
