Read serial data without PC on GLCD

Monday, June 9th, 2014

Hemal Chevli wrote an article detailing his new tool the GLCDTerm that reads serial data without PC on GLCD: I’m calling it GLCDTerm(spin-off from GTKTerm), this handy tool reads TTL serial data and displays it on GLCD. This is the first time I’ve used a GLCD in any of my projects. It runs on m328...

Build a low speed scope with a PIC18F2550 and a graphical LCD

Wednesday, March 21st, 2012

Steve build a low speed scope from a PIC18F2550 microcontroller and a graphical LCD. The MCU takes 60k samples per second from it's analog-to-digital converter. It proceeds to process the signal and display it and some basic information on the screen. Steve left the source code, and the schematic on...

KS0108-based Graphic LCD overview

Thursday, December 29th, 2011

Raj shows how to interface GLCDs with KS0108 controllers to PIC uCs. He covers the protocol used, LCD memory mapping, and how to write up the firmware using microC compiler. The use of a graphical LCD (GLCD) drastically changes the look of your project. It provides more freedom for presenting...

DC power supply monitor with GLCD display

Friday, October 28th, 2011

Here is a project built to provide a DC power supply with a GLCD interface: This power supply monitor is intended to measure the voltage and current of a DC power supply, and continuously display these values on a 128X64 pixel LED backlit GLCD display. Ezflyr built it for his...
