I have pl2303hx programmer and i want to program atmega328p-pu with arduino.
it does not have auto reset so i followed this circuit for auto reset.
I have also attached and LED to check the LED on off.
When switch is unpressed then it is off.
I have used this diagram:
Firstly i press and hold the reset and then click on upload.
And when it show uploading i count to 3 then release the switch.
But then it gave me following error:
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x01
And the only light which is on in pl2303 programmer is green.
Now new problem.
When i plug in pl2303 programmer green and blue light both of then are on by default.
And the same error is comming up while send the sketch.
The only addition is blue light with green light.
I have checked my programmer with checkChipVersion tool which tells which chip i have.
So it is confirmed that my programmer is still working.
One more thing i would i like to tell is the first time i tried to programm the atmega328p-pu i also connected an LED with PIN 19 and it was glowing it seems the the atmega328 was already having the code now the PIN 19 LED is not glowing.
I am using the 5V provided by the pl2303hx to power atmega328p-pu
