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
Hi friend, I am in to strange problem could not understand yet. I have been working with ATMEL MCU atmega8 with many projects using UART, SPI, i had no problem, but now recently, i bought few atmega8 and using Internal Osc. 4Mhz but it is not working and ihave connected another device at SPI it is also not working. the MCU TX / RX not working. B
I program atmega8.Now i want to protect the chip so that no one can read its hex code.What should i do?

I have been checking my inventory of ATMegas and here are the results: ATMega32L Plastic Packing (Reel of 10) SPIEN fuse programmed ATMega16L Plastic Packing (Reel of 10) SPIEN fuse programmed atmega8L (Reel of 25) 7 already used 18 present 7 used did not have SPI fuse programmed, checked the remaining 18, none of them (...)
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 used an atmega8 whose fuse bits was not set to use an external oscillator(fuse bits were at factory settings), in a circuit with a 12Mhz oscillator and powered on the circuit. needless to say the program did not work. Now when I try to program this atmega8, Avrdude says "AVR device not responding" Is there any way (...)
Hi, Just program my atmega8L on PonyProg with this Now after WRITE button I can't read it anymore //:cry: I think I had DISABLE the SPIEN pin? but the SPIEN is greyed...
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 a atmega8 i can program it but it theres no output at pc0
65492 These setting for atmega8 are not working. I want to use internal oscillator. Thanks
Good morning at all. I want built this: I need to change the fusebits of the atmega8. 1) first i flash with hex files and only AFTER i change the fusebits? 2) When i have changed the fusebits (ext. rc. osc. to 12 mhz) , i can not do it anymore (reprogrammed)? 3) the setting with
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
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 ? .
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.
Hello Everyone I've read some tutorial about atmega8 USART. I tried to write a simple program, which send a character 'a' to serial port. I used Realterm to connect to MicroController, but received character was not direct (wrong text). (I also tried to use Hyper Terminal, but sometime text is displayed in screen (wrong text), sometime nothin
I used in the first time an external crystal to 12 mhz and for the setting, i selected ext. RC Osc. 12 mhz . If i want to change the fusebits of the atmega8 for other use, the connection with the square generator is the only way? There is no other way? Now this is even more conf
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, 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
Hello! That is right. u can enable the serial mode by programming the microcontroller in parallel mode. I made the same mistake with atmega8. I worte a program for Pic16F877 and reenabled the serial mode of programming by only reprogramming the fuses of atmega8. Just read the pdf of the controller, write a program for 8051 or any (...)
Hi I'm not sure but as I remember, Attiny2313 has no internal clock. if you set fuse bit of atmega8535 to work with crystal then you can not program it without any crystal. regards
Hrm, that program doesnt work either .. when i select detect i get this msg: Checking programmer type ... Timeout during COM-port read operation! Supported programmer not found on Com Port 2 Programmer is on port Com2, cause i tried to connect to it from avrstudio. It connects to programmer, it updated firmware on it, but cant enter program
