avr usb programmer

[Zaved]

 my question to all the experts of this site……

i new in avr… i saw the avr usb burner usbasp… i hope you all have heard of it… it is written that the crystal must be 12Mhz this mean the avr device must clock at 12Mhz.. i have used ATmega8L instead of ATmega8 the atmga8L can max clocked up to 8MHz then how come my device is still working…..

8 Mhz is Internal Clock, 12 Mhz is External Clock produced by Crystal Oscillator.

not exactly the same the internal clock which can be set is 1mhz(default)

and externally we can use upto 8 or 12 mhz (depending upon he chip)

 

 

 0 – 8 MHz (ATmega8L)

 0 – 16 MHz (ATmega8)

How can i use the usb programmer to write programs to the atmega16 microcontroller

Hi Pinaki,

If you are using AVR Studio, complie the code first and it will generate a .hex file. You can use another burning software like AVR-BURNO-MAT to load the hex file using USBasp.

thanks,

can u just say me the steps because i used the same software but it is showing some error .

Hi Pinaki,

There is nop complex procedure actually. Build the code using AVR studio, using AVR-BURNO-MAT select the .hex file generated and load it.

Before compiling using AVR studio make sure that you have selected the exact part number of your device, for example

The errors can happen due to the improper programming circuitary also.

 

 

 

 

 

 

 

 

 

Please post your error dialogue to get more help.
