hi everyone.
i am new to arduino programming.
When i interfaced JHD162A LCD with my arduino (ATMEGA 8) and uploaded the "Hello World "
program in the arduino library,i get blank (no display) in the first row and black square boxes in the second row.
I connected a 5K pot on pin 3 on the lcd and i was able to adjust the contrast of the lcd.
but why this problem ? please help me..
Any help will be appreciated..
thanks in advance..
Are you using the LCD routines within the Arduino IDE? Are you using pin 9 or pin 10 for 'LCD E' ?
If the contrast is adjusting, then the LCD isn't initialising..... Incidentally!!! Is the display upside down... An uninitialised display has black squares on the top row...
yes,the lcd routine is within the arduino IDE.
I am using pin 10 on arduino for LCD 'Enable'.
i see black squares in bottom row and first row is blank.
since i have only little knowledge on soldering,i connected the lcd pins onto a breadboard and then to the arduino pins.
I use arduino 1.0 and windows 7 as OS. I am using arduino ATMEGA8.
now it works fine!!
There are few problems in the arduino lcd library..
I tried the updated library which helped me connect the lcd properly to the arduino and then it worked well..
