friends, I have a new project and i got a problem on it. first i don't know how to make a counter using 74ls190. secondly i have a problem how to make 1 bit delay on my input signal, some says that i can delay my signal using cd4042 but it doesn't work at all
i'll wait for your suggestion for...
i2c program
i ever made an project before using at24c64 as eeprom and atmega32 as a master to read or write eeprom
basicly u must understand about i2c addressing, there are 3 address pin on at24c64/c08. here in my sample the address pin is connected into ground which is mean i set the device...
lcd programming using atmega32
have u check the port data, port control??? u must use the same port that described on the program.
for example, if your program lcd initialization said that port data on PORT D then u should put the port data on PORT D.
most of lcd problem is about the conection...
winavr code wizard
offcourse WinAVR, but the only problem using winavr is u should be able to setting your own "make file" .but don't worry u can googling for that, you'll find a lot of tutorial about winavr.

using at89c51
i sugest you to used L932D as motor driver, output from mikro pin directly conected into L932D to control the motor spin. if I'm right one L932D can drive until 2 motor DC .
thank's dude for the reply, but i've found the problem. i realized that my micro isp turning off after i put it into my friend standalone programmer.
have you ever read datasheet errata for at89s53 and at89s8252 ? Atmel said that after reset high there's a glitch on sck that make any serial...
isp at89s53
yes i used parallel port isp programmer, the software are ponyprog and isp-programmer by khisernaeem.
when i used the programmer to programm at89s51 and s52 it's work properly, there's no something strange. but when i put at89s8252 or s53 all i can do just read hiks hiks...
