This is my first project with writing in Assembly language, I have tried to produce some Assembly code for Interfacing SHT15 sensor with the atmega8 ?C.
I would be very grateful if someone could check my code, and correct errors you may find. Please note this is my first attempt at Assembly programming, so I am sure there must be som

i am considering to design a frequency counter using atmega8, i want to use asynchronous operation of timer/counter2.
frequency counter developed by pic asynchronous timer is ther.... but i want to make it with atmega8.....
need some suggestion..

Hi i am new to this hehe. So i put this in question way easy to get answer?
For your guys info me havent learn how to program a chip so need help here.
1. Is there any way to replace the atmega8 with something that does not need to do program
2. I cant find the pressure sensor model which is MPXV5100GC6U but i can get MPXV5100GC7U instead

i have used atmega8 mcu for my digital stopwatch application . and i programmed the IC with a C code using winavr compiler. then my stopwatch is showing minutes and hours -but it should show seconds and minutes.
i have used atmega8 micro with a crystal of 16Mhz.

Why does the code below send continous no of 'U' in proteus simulation virtual terminal.I am using winavr
for programming atmega8
By putting "cli();" instruction in ISR should have disabled interrupt. but 'U' is being continuously delivered.
what is the problem here??

Below is the C code for handling an external interrupt.
The initial value on PORTC is 0;
When an interrupt occurs it increment the PORTC by 1;
I used the winavr to convert the c code into hex code, then loaded the hex code onto the chip (avr atmega8) for test. The values on PORTC change randomly every an interrupt occurs.
Can anyone tell me

I need Assembly to Hex converter for AVR atmega8, ATmega16, ATmega32.
I am very much familiar with 8051 and now I want to start with AVR
I am writing AVR programs ONLY in assembly language.
Please help me in this regard.
Waiting for your replies

If you have used 8051 then you're familiar with programming. So, you should download the datasheet and if you go through it, it shouldn't take you much time to port your knowledge to atmega8. As stated, AVR Freaks has plenty of info and tutorials. You should also choose your required compiler and language and I re
