Standalone atmega328p-pu
hello
i trying make standalone atmega328p-pu. below connection detail made.
pin 1 vc through 10k resistor.
pin 7 vcc
pin 8 gnd
pin 9 & 10 16mhz crystal. each lag of crystal connected 22pf capacitor , remaining leg of capacitor gnd.
pin 19 220ohms led gnd.
pin 20 vcc
pin 22 gnd.
(connection mentioned in http://arduino.cc/en/tutorial/arduinotobreadboard)
here vcc , gnd supplied arduino uno board.
atmega328p-pu has blink code uploaded.
it not working.
when troubleshooting, removed both 22pf capacitor , led connected pin 19 started blinking.
so now, can make pcb using crystal , without capacitor ?
help !!
