I change the fuse settings manually to 99 E1, which is the factory default (atmega16 datasheet), as the programmer software does not have any reset to default option.
My programmer is a 35000 rupees programmer. Im sure it can do the work. For comparison an atmega32 costs 180 rupees here. I have told you previously I dont want to buy any other circuit
I change the fuse bits and program it. But when I read it it gets back to same value as if it has not been changed.
Is there a special procedure to change fuse bis? like you have to change a certain bit before changing fuse bits
Its not exactly locked. My chip is recognized only by the universal programmer, not by any spi programmer like serial programming using ponyprog or usbasp.
When I program a hex file (using universal prog) to light any LED (PD7 or PD6) it gets lighted. But when I tell it to flash (1s delay), it...
I wanted to program my Atmega32L to external crystal oscillator using Ponyprog. Targe fuse settings: high: C9 low: EF
Previously it was default factory setting: 99 E1.
When I pushed write all in fuse settings in ponyprog, I got "fuse write failed" and it did not recognize the chip after that...
I have not made the schematic. I am directly soldering the connections on a general PCB.
Till now I have connected all the input connections to Atmega16 from the USB:
USB pin2 ---> (ICP1) PD6 through R1
USB pin3 ---> (OC1A) PD5 and (INT0) PD2 through R2
and other required diodes and caps.
Now...
Thank You very much alexan_e. This is what I was looking for.
I haven't tested it yet but the code seems right. I'll reply again after I have tested it. Thanks again
Thanks randell. I am aware of all these changes in Atmega8 and 16.
What I want to know is where to connect in Atmega16 and what are the corresponding changes in the firmware.
Like for example, if you look at the USBasp circuit for Atmega8, two LEDs are connected to ADC PORT which is PORTC. But...
Hello
I have 5 atmega16Ls and I want to make a cheap AVR usb programmer using one of them.
I came across the USBasp programmer on fischl.de But it was using Atmega8.
I am using Atmega16L for robotics for a year now an I am good with digital circuits.
What changes do I have to make to the...
