Hi,
I am now doing a project based on this website
https://instruct1.cit.cornell.edu/courses/ee476/FinalProjects/s1999/sam
The chip that I used is exactly the same with the website which is Atmel 8515. After connecting the circuit, my LCD only shows black boxes. Anybody can help me with this?
I have no idea what a STK500 is. Is it compulsory to use it? I assembled the code in the website using AVR Assembler 1.30 then downloaded the code into the chip using ALL-11 Universal Programmer.
As for the circuit diagram based on the website's description, the numerical keypad is connected to port D and the function keypad is connected to port B. Both LCDs are given a common data bus and then driving them with their own set of control lines. I am using 4 Mhz crystal with 30pF capacitors. Is there anything which I missed out?
I really hope somebody can read through the website and give me some
assistance because I have really no idea on what to do now. I need
some help fast!
Thanks.
