3. How do I set it up as the startup image when I powerup on the LCD?
4. If I can't set it as startup ...

What is a Null serial cable?

That might be the problem I am having, it could be the cable I am using to connect between the STK500 and the LCD. I am currently using a male to male serial cable between the STK500 and LCD. Cause the STK500 has a female DB9 output and the LCD ...

I bought the 4x4 keypad from your store and the LCD GLK240-25

Looking at the manual for the 4x4 Keypad I'm not sure which end is number 1 pin. So if I was to look at the keypad from above with the buttons facing at mee. is Pin 1 on the leftmost side?

Also, since the LCD allows up to 5x5 keypad ...

Hey,

Not strong with coding yet as I am just getting use to the micro-controller

Was just wondering if there are some working sample codes I can look at or tutorials that will give me a good start? :)

From looking at the Manual

How many pins would I need to interface with that LCD?

Hey

Wasn't sure which forum to post this in as there wasn't a general hardware section but hope this will still help me :)

I am using the ATmega32A for my micro controller. the microcontroller has SPI and some I/O free. I will be using the USART for something else

For my exercise interface ...
