Burning atmega328-pu and atmega328p-pu bootloader




Burning the boot loader in an atmega328 could be somewhat tricky but if u follow these steps correctly youll be able to bootload any type of atmega328 micro controller ..

Step 1: “setting up the hardware”

-List of stuff you’ll need:

– An Arduino board (any type)

– 18-22pf capacitors (x2)

– 16 MHZ oscilator

– Breadboard

– 10 Kohm resistor

– Jumper wires

– ATMEGA328-PU or ATMEGA328P-PU

– Bread board

.

Assemble everything as shown in the figure (on a bread board) :

– arduino board (pin10)->breadboard (pin1)

– arduino board (pin11)->breadboard (pin17)

– arduino board (pin12)->breadboard (pin18)

– arduino board (pin13)->breadboard (pin19)

– (pin 7 ) and (pin20) of breadboard ->+5v of arduino board

– (pin8) and (|pin 22) of breadboard ->gnd of arduino board

– 10 Kohm resistor from(pin 1 ) to +5V

-16 MHZ oscilator from (pin 9 ) to (pin 10)

– 18-22pf caps : first one from (pin 9) to gnd ,second one from pin 10 to gnd

Now for the hard part made easy .
