![]() Glcd supports text regions and scrolling. ![]() Glcd is very fast but currently only works for ks0108 and sed1520 displays U8glib (which is maintained by Oliver Kraus) Google Code Archive - Long-term storage for Google Code Project Hosting. Once the glcd and pinout has been identified, there are two very nice libraries: If you have labeled pins on your glcd that would fully identify it. I was able to find this datasheet: 4GLM 12864 1 | PDF The labeling on the back seems to indicate a ks0108. Use the wrong one and it can damage the glcd. It is very important to get the proper datasheet. Where as a ks0108 will have these pins instead The way to identify a st7920 module is you will see pins labeled: St7920 and ks0108 modules have similar looking pinouts but are very The tutorial you linked to is for a glcd module that uses a st7920. Turn all pixels on or all pixels off depending on direction of the pot) (I'm assuming that rotating the contrast pot can The fact that you got the backlight and contrast to work is a good sign that the powerĬonnections were all correct. It is possible to damage the glcd with incorrect wiring. So when playing with glcds guessing on the wiring is not good since The glcd module can quickly be burned up, particulary if the power The big problem is that if it is hooked up incorrectly They use different chips sets and have many different pinouts.Įven modules that have the same chipset on them can have different pinouts Glcds are not like the character hd44780 displays in that the hd44780 displaysįor the most part all use a compatible pinout and all use the same electricalĪnd s/w command structure to talk to them. Serial.Did the seller specify what chipset the glcd used?Īre there any labels on the actual pins on the glcd?īefore you proceed any further, you need to identify which glcd module you have.Īnd more importantly find it's datasheet.
