Optrex LCM 51852 initial issue
2005-08-01 by jones3hsu
Dear All, I had a project LPC2214 with Optrex 51852 LCD Module. Now i have two request : 1. I bought a 51852ADM LCM Module from Mouser. I can't get display on the LCM when i use internal LCD Voltage supply. I try to measure the V1~V5 and Vout. I can get Vout= -6.4 and V1=2.96V,V2=2.5V,V3=1.12V,V4=0.72V,V5=0.24V. I guess the root cause from LCD Drive voltage, bacsue i try to read out the DATA from LCM , that's correct. I checked in your web-site the reference schematic is used external Power supply. May i can use internal power supply ? or Do you have any suggestion ? 2. Anyone can suggest me the small GUI that i can implement into LPC2214 ? Tks a lot.
