Support Forum » Can't Write to MCU

Hi,

I've written successfully to the MCU previously. However, I've moved on from the Temp Sensor project to the blinking LED. I've removed the LCD. I'm trying to write the blinking LED code to the chip. I type make at command prompt (Windows XP) and all I get it this:

C:Documents and SettingsAllanMy DocumentsCodetempsensor>make avrdude -c avr109 -p m168 -b 115200 -P COM3 -U flash:w:tempsensor.hex:a

Nothing happens after this...

Please help.

FIXED

My error, I connected PIN 15 to GND instead of 14 (RESET).
