Hi, need me help. I make programmer for AVR microcontrollers, with atmega8.But I'm not sure whether I correctly set fuse bits. I am read datasheet but I don't understand fully datasheet. I am set low fuse bits 0xD9 and high fuse bits 0xE1. I using 12MHz quartz oscillator. Lock bits i don't touch and it is set as default at (...)
Hi , I have an atmega8 with its clock fuses unknown !! I want to program it but I dont know what type of oscillator to use is there anyway to restore the fuses to original state (1 Mhz internal oscillator)??? I have a USBasp programmer only .
hii . i write a wrong fuse bit for my atmega8 . and i can't programming it via my usb asp programmer . and in data sheet i find an parralel high voltage prorammer. and i find this video high voltage can reset my fuse bit ? .
hi guys, i am not finding any read lock bit in atmega8, is ther any read lock bit or fuse in atmega8?? how to read protect a atmega8?? please help arnab/vu2bpw
Possibly you set up an external clock source. Programming AVR fuse bits ? oscillator settings Life-giving to atmega8
Hi, I want to disable the hardware reset pin of atmega8 and use it as an IO pin. Can any one please give me a C / WinAVR code example of how to do it? Thank you.
hello everyone! i want to see the atmega8 adc result on my pc i am using bascom avr terminal emulator displaying the following code whatever i print ??x?x?x??x can any one help me
I program atmega8.Now i want to protect the chip so that no one can read its hex code.What should i do?
hi experts How to recover wrong fuses settings on a AVR say atmega8 ? may be isp disabled (cannot detect chip error-24).don't suggest HV programmer method pls suggest any easier way to recover . i am using pony prog2000.thanks.

Hello. I would like to know if someone had made this arrangement Satfinder Elektor March 2011 to find out what fuse box for the atmega8, I'm a little lost (even many) I visited the site [http : / / but I can not understand how to take control in the dropdown menu, I know the installation uses an
I meant the atmega8 datasheet. Assuming your observations are correct, I see two possible reasons, why the device can't be accessed by a serial programmer: - It's damaged - The SPIEN fuse has been previously reset by a parallel programmer. In this case, a parallel programmer would be needed to re-enable it.
Hi i have a atmega8 i can program it but it theres no output at pc0
It is an USB RS232 I/O port module ? an USB-RS232 adapter based on the following project:LINK . The device uses processor atmega8 with quartz
I'm divorcing atmega8 from my work bench. Its a bad one. PIC is much better. The chances of this being m8 fault are close to none unless you have a faulty device. You can blame your code or your compiler, your choice ...
Jtag enabled etc There is no JTAG in atmega8. @Rohi123 Looking at the attachment fuse for internal 8MHz is correct. Do you need bootloader which is selected for 1024 bytes in your attachment.
When you start the programmer, there are three tabs, use the third tab for fuse bit settings. If you wish to write those bits, use the check box and then write it. see the attached image. 89255 the value of fuse bits and lock bits can be calculated using the
Can anyone tell me how to use an internal RC oscillator as a clock source in atmega8? I have searched a lot about that and found, there should be configuration bits programmed using ponyprog2000. But when i program configuration bits my program cant be run and when i connect external oscillator between XTAL1 and XTAL2 the program execution speed
In an attempt to get reliable firmware for 89S51/52 USBASP programmer I tried to copy hex file from a ready made programmer as I could not find what firmware to use from the that process I copied the lock bits also. Later I realised tha
Hi everyone, i try to blink a led to learn avr series as hoby so i wrote this code below: #define OUTPUT 1 #define INPUT 0 #include "main.h" #include #include "util/delay.h" int main(void) { DDRC = 0xFF; // PC0..PC3 as output PORTC = 0x00; // all PORTC output pins Off while(1) {
If you have disabled reset then you need a parallel programmer. The simplest solution is to use another atmega8 to reset the fuses, refer to 101505 The more complicated solution (that can work with any AVR) is Atme
Hi friends, does anybody knows or has some materials about realizing a circuits which works like a fuse. This Circuit must be very fast and must switch off currents about 30Aac. Thank you for your help Best Regards Vauxdvihl

Hi, I first time try to work on AVRs(Atmega64). When try to program it with Bascom11173 and STK200. It looks it work only first time, when I do some changes in fuse bits it then never again be connected/detected. Now the device is no more detected by Bascom, also tried PonyProg2000 but could not succeeded. My question is that is there any po
Hi, I programmed the RSEDISBL fuse of atmega8 to get one more I/O pin, then the ISP function not worked any more. Is there any way to restore the fuse to default value? My programmer (superproLx) does not support atmega8. Regards, Epegic
I want to build a simulator for atmega8,where can I find reference imformation?
I need a accuracy resistor in my design, so i want to use fuse trimming. But how to design this trimming format! Should use metal fuse or poly fuse? where to find some docs about fuse trimming!
Hi, I have an atmega8L that its RSTDISBL fuse bit is cleared and now its RESET pin is configured as an IO pin, I want to reprogram this device with an ISP programmer, is it possible? If yes HOW?
I intend to use this electronic I'm dount that the Q3 is wrong connected. If it is connected as above, U(R2) = U(BE). When U(BE) = 0.6, it would conduct but the current will flow from C to E (or from 0V to +V --> I can not understand this circuit if Q3 is connecte
There are three fuse bytes in some ATMEGA devices. I am working with ATMEGA162, and ICCAVR only shows two of them. Beside, I suspect that only the lower byte is displayed correctly, since I get a non-default values for the middle byte with a unused device. Somebody with experience with this??
It maybe good chance to "change horses" (read: select a CPU family) as I think there are out there ready-to-go projects based on PICs or 51-family.. These project may come with source code and this will save you a lot of time (unless you are "fluent" in, say, C language, and C has this good thing that it can be used with almost every CPU family)..
Can anybody help me find a good aproximation type so I calculate a track as a fuse? xxtigerxx
Hello, 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 have a question about the figure i have attatched consider that the power is turned on simultaneously on both the circuits of Fig 1 and Fig 2. which fuse will blow first?? i think that both the fuses will blow at the same time. am i right?
Greetings, Please forgive me if this is not the right forum for the following: My goal is to write a program which will read a .JED file and program a CPLD via JTAG (using a pretty-fast/flexible digital IO board.) I understand the JTAG side, and I've written a JED-file parser, but am stuck mapping the fuse-list to
Hi, I'm needing the schematic for the BootLoader and JTAG (Not for debug, only for load the program and blow the MSP430's fuse). Does some one have them? Thanks in advance. Emanuel Cassimiro da Silva
