Hi, Last time i worked with atmega32 I Accidently Programmed my Chip (in ISP mode) Wrong and i Disabled the SPI Enable fuse Bit and i think I had programmed my Fuse bit Wrong that i Can't Program (read or Write )My chip any more(i checked it with ISP Programmer). Is there any solution To Change My fuse bits and unlock the chip and make it us

hi every1 how do i program the fuse bits of CKSEL? do i have to set these fuse bits if i wanto use an external crystal?? or do i just leave them as they are? thanks...
Hi mohamed saleh it seems that you are a beginner in a Mc's world, i had read your post about "PIC or AVR",if you want the best choice i suggest the AVR microcontrollers, like "Attiny2313, atmega32, Atmega8515,Attiny26,...". If you decide to use AVR, i suggest "Pony programmer to burn your AVR". Any way if you decide to use PIC or AVR i

Im using ADS1213P in slave mode and i am using atmega32 to read data from it. I am first writting the instruction register(so as to write data to COMMAND REGISTER) then i am writting data to the 32bit command register.I am trying to do this when the DRDY(bar) goes low for the first time. then when DRDY(bar) goes low for second time........
Hi there everybody! I would like to build something similar to the "makey makey" but instead of controlling a computer, i simply want to control 8 other pins on the atmega32. As i understand i have to put a large pull-up Resistor on the input where the marshmellow would go and then ground whoever is touching the marshmellow. But where i ge

hello im using proteus 6 but i see 28 pin package for atmega16 and atmega32 , and portA is not in atmega ports in proteus 6? can i chang it to 40 pin or is any update to repair this ? because in fact atmega16 is 40 pin but in proteus i see 28 pin package. if you know how can i change it to original 40 pin tell me plaese. thank you
hi, iam using pony programmer to pgm the avr device via parallel port. iam trying to programme the at90s8535,atmega8535,atmega32,all are ok. but iam try to programme the atmega128. its fail. its say no device found. how can i solve that. any one have experience that.
here is an AVR ISP programmer is really very simple just a DB25 connector and 4 resistors.I have used it with Ponyprog and it works really fine(at least programming my atmega32) so give a try... regards maxer
The ATmega16 or 32 would be my suggestion for more I/O /Bingo i suggest you atmega 16 and atmega32 because have more properties.
1) firstly the robot must build up a map data base using a sonars. 2) secondly it will navigate throgh the enviroment using ultrasonic sensors for detection and observation each time will make a matching between the current sonar reading and the map data base that is stored some how in the robot's microcontroller (atmega8515 or atmega32 which i w
hi guys i am faced with this problem that after writing my code and after building the solution when i just move on to download it to my mcu through my setup of avrstudio4 with winavr as compiler and stk500 attached to comp via rs232 and to target via isp 6 pin cable ..... the interface do open for setting the various values like fuse
hi friends Actually my problem is concerned with programming atmega32l (not atmega32) on stk500 . the tools i am using are: winavr with avrstudio4 (ide) version 1.3 build 460 I would like to state the problem in detail relying on the fact that atmega32l is supported on stk500. The bug is that (...)
First, u must use external or internal voltage reference on the microcontroller so that u can use the ADC. Using external voltage reference must attached on pin AREF. I don't know about ATMega128 internal ADC yet, but if it is atmega32, u can change the register ADCSRA, ADMUX, and SFIOR to control the ADC. Refer for ATMega128 datasheet if you wa
