Mike B 7 posts Popping In	10-05-2007 18:43 Hi, Has anyone any idea on how I can get some basic information (and a circuit diagram) on the GLCD E Blocks display, so I can start to hook it up to my own circuits, please? What voltage is applied to the terminal block( is it the 14V for the display backlight?) Does this voltage need to be current limited? Does the module also need +5V? There is a voltage regulator on the module - does this cover the 3V for the GLCD chip? I just need to feel comfortable before applying power - the rest of the interconnections are digital. Thanks Mike

BenMatrix 1 post Popping In	11-05-2007 12:28 Hello I have not been able to find your post in the MatrixMultimedia Forum are you sure you posted there correctly. There is normally quite a large community willing to help. All of the information regarding the Graphical LCD is in the Eblocks support center. Here is the link. http://www.matrixmultimedia.com/eblocks/index.php The Graphical LCD requires a 12 - 14V supply on its screw terminal. As long as the current is fairly small it wont damage the module. The onboard regulator sources the 3.3V required for the LCD circuitry and the 12-14V sources the backlight illumination. Hopefully this will anwser all of your questions. Ben Rowland Technical Support Matrix Multimedia Ltd support@matrixmultimedia.co.uk
