Hi, Just a couple of points, 1) When you first start the ADC, DO A DUMMY READ as the first conversion is unreliable. 2) In order to start the ADC in free...
Hello, I am new in field of microcontroller,And i want to buy a deveploment board for AVR and 8051 too.Please any one have any information then please replay ....
Hi all, please,can any one help me? I need a simple example for using eeprom in codevision compiler,because I had tried the example in the help of codevision...
hello every body, i downloaded a jtag_iso programmer/debugger from avr portal,i make one and download code to the atmega 16 .when i connect it to to avr studio...
hi.. recently i bought 2 atmega16l...none of them responded when i tried to program them!! is there anyway to check whether the atmegas are dead??is there...
ALL ICs are checked for quality upon shipping, to ensure correct operation. They were ok until you plugged them to your PC. Wether they are still operational...
Hi all, Am new here, new in AVR field, and using CodeVision AVR. I want to learn about the TWI for my work. I search a lot but still get confused, my current...
You most likely set the fuses wrong. There is a way to revive the Atmega8 from such an event but it's complicated and prone to frying the IC. Get a new one and...
do this: Get the mega128 and other uC's datasheets. Open them. Go to TWI chapter. Read. Don't understant? Read again. Don't understand? Post. Or do you expect...
The voltage factor (VCC) shouldn't be a problem, especially with the L variant. I have the exct same kind of programmer (uses the parallel port but it programs...
I recently discovered (well, it's new for me) another way without high voltage. You have to apply a 1MHz (frequency not critical) signal on the crystal pin and...
I did already, the problem is that in the datasheet (atmega128/8), it only gives example/clear picture about Master/Send, and at least I have to understand...

...  I found out what the problem was.  When I compiled the program the make file was expecting PROGRAM_NAME.c I didn't give it .c suffix  and the...
I'm not really sure the preprocessor computes a good value for the data rate to be stored in the UBRR register. use value 12(4800bps, 0.2% error rate, 1Mhz...
Hi All, Thanks for all your replies, i have already designed such circuit which i required and it's working fine. Soon i will share that circuit with coding. ...
