The hex file for my project is no exactly 8880 bytes (9216 Bytes on Disk). I'm still able to load this hex file without any problems in the above 8K Micro controller. I was under the impression the 8K of the AT89S52 was the storage space, but this does not seem to be the case . Can anybody share some light on this for me ? ------------------------------------

Hello! Greetings from Brazil! Can you recommend an ATMEGA with 2 UARTS? The reason that we will use UART is simple, its more reliable than software serial. I don't know if everybody agree with that. Thanks! Cleber ------------------------------------

I've just got back into playing with micros after an absence of 25 years. Wow have things changes - for the better. For the current project I want to hook up a 2x16 LCM with the Mega168P and thought hea, there are LCD everywhere - it should be easy to find a nice tight set of well documented LCD functions that I can use and are built to be versitale. I will not be assuming any such thing in t...

Hello all, I have a Robostix and when I go to their Wiki page it has the all of the C code and headers except the 'lcd.h' header file. Does anybody know where I can get this file or at least a working package. I'm trying to learn how interface sensors to this thing and I can't tell if I'm getting good data. I also have an Olimex ATMega128 board that I think works. I just need to p...

I have come across something that I do not quite understand. I am running a simple code that uses 4 pins as inputs and the rest are outputs. I write in assembler code. The program runs fine in simulation but i found a glitch when used in real life. In my code there was a couple of dozen places where there would be most of portB on as output high and maybe a single pin high on port A or D. To cut ...

hi all,, i have a small project using attiny2313, i'm trying to handle two buttons using pin change interrupt. the problem i got that, sometime it gives a good output by send some byte using uart communication, but sometime its not working. i've read about debounce handling (i'm not sure if its correct) but i dont know it mutch yet. This is my first time make a program to handle external i...
