LCD Kit Arrived!

Posted by Erin, the RobotGrrl on Thursday, April 10th, 2008

A big huge thank you again to uC Hobby for sending me an LCD Kit! Now I can FINALLY use my LCD that I bought at a HAM radio thing.
I have a few problems with it… for instance, I don’t know what the pins on the right hand side are supposed to connect to. The 1-16 pins are pretty straightforward - but what on earth are those other ones for?!

Furthermore, I accidentally might have exploded the entire thing. I’m sleepy after school, so I reversed all the connections to 5V and Gnd. Ugh. The chip was so hot! I don’t think they’re designed to resist that amount of hotness. :( I hope I didn’t break it!

Here are some pictures

I hope I can figure it out today It’s not broken until it’s broken! I still have faith.
Thank you uC Hobby!

   Chips can stand over 150 °C, by that you would have mark on your finger if you touched it.

   Also one reason for the chip on the LCD to get hot is if the R/W line is set to write the data port on the display becomes output and if the AVRs pins are also output there is a short circuit between.This causes the chip to get hot but it should still work as new.

   The Pins on the side are just for LCDs that have a 2×7 connection instead of a 1×16, like this one: http://www.allelectronics.com/cgi-bin/item/LCD-107/365/24_CHARACTER_X_2_LINE_LCD_W__EL_BACKLIGHT,_USED_.html
