Ok ajay, i have a problem with the software. i already download all software that u give in the 1st step. but when i try to install my computer will be stuck. i try to install it to other computer, but it still same.. and 1 thing, can u give the full schematic for avr? becoz the schematic that u give only for interface. so if u dont mind i want the full schematic for avr becoz i want to compare it with my schematic.

Thanks

also... I have installed the software in my PC i don't feel any problem.. can you try a different version of AVR studio.. that might help..]]> contact@nospam.com (Ajay Bhargav) Mon, 03 Sep 2007 01:01:51 -0700 http://www.8051projects.net/forum-t1700.html http://www.8051projects.net/forum-t1700.html
ok ajay, now i can install the program. Thanks. the problem is the file that i download was corrupted. thats why i cannot install the program. hehe ]]> contact@nospam.com (Ajay Bhargav) Mon, 03 Sep 2007 02:53:47 -0700 http://www.8051projects.net/forum-t1700.html http://www.8051projects.net/forum-t1700.html for AVR its very simple..
everything is labeled.. MISO will go to MISO of AVR
MOSI with MOSI of AVR
SCK with SCK of AVR
RESET with RESET of AVR
LED with simple.. LED on the target board.. or u can leave open if you don't want to connect
Led is connected like this.. on the target board..
LED ---|<|-----/\/\/\/\------VCC

For more information on pin configuration look in the datasheet of your AVR.]]> contact@nospam.com (Ajay Bhargav) Mon, 03 Sep 2007 03:35:08 -0700 http://www.8051projects.net/forum-t1700.html http://www.8051projects.net/forum-t1700.html contact@nospam.com (Ajay Bhargav) Mon, 03 Sep 2007 16:11:03 -0700 http://www.8051projects.net/forum-t1700.html http://www.8051projects.net/forum-t1700.html LD Rn,X+/Y+/Z+ , this instruction.i'm curious about the Z+. izzit this code is for the next pointer?so if i only want to load in only 1 data from 1 address then izzit Z is enough?]]> contact@nospam.com (Ajay Bhargav) Tue, 30 Oct 2007 21:34:24 -0700 http://www.8051projects.net/forum-t1700.html http://www.8051projects.net/forum-t1700.html i.e.
LD Rn X+
or
LD Rn Y+
or
LD Rn Z+
That command load the register Rn with the value stored at location Z and then increment Z.
if you just want to load from location Z and do not want it to increment then you can use the following command
LD Rn, Z
this will load register Rn with value stored at location Z.]]> contact@nospam.com (Ajay Bhargav) Tue, 30 Oct 2007 21:52:37 -0700 http://www.8051projects.net/forum-t1700.html http://www.8051projects.net/forum-t1700.html hey milky
if u want load only one data from address location of ram means , u can do following instruction

LDS r16,$0061
this instruction will directly load the data from ram location $0061
and also if u want store directly means

STS $0061,r16

this will store the data to the location $0061

I'm begginer in AVRstudio and winAVR. I wrote lcd .h and .c file, but when I use .h in other project, building final files fails:

../test.c:7: undefined reference to `LCD_init'
../test.c:11: undefined reference to `LCD_cursorxy'
../test.c:12: undefined reference to `LCD_sendstring'
make: *** [test.elf] Error 1
Build failed with 3 errors and 1 warnings...

lcd.c was checked before and works fine. I don't know where my mistake is.

Can you help me???

while(!(key = getkey()));
key = translate (key);
lcddata(key);

I understand all this statemnt, but not working in my project. LCD display different characters. Can you tell me, what I'm doing wrong.
