Character LCDs / NHD-0420D3Z-NSW-BBW-V3 how to interface
« on: May 28, 2014, 07:39:23 AM »
Hi,

i am new with LCDs. I try to interface NHD-0420D3Z-NSW-BBW-V3 with my LPC1768 with RS232 but the screen display only some nonsensical symbols. I use default baud 9600 and i take care the execution times. I saw your code here http://www.newhavendisplay.com/app_notes/Serial_LCD.txt and i do the same i think except from this
        BAUDCTL = 0x08;
   SPBRG = 207;
   SPBRGH = 0;
because i dont know how. these are the registers of PIC16F690??

edit: when i send prefix 0xFE the screen display a nonsensical symbol.
i use the same communication format. :/
 
thanks
