Hi, every body i m fighting to upload sketch to UNO from xp with arduino 0022 On my computer i was having 2 COM PORT showing up, despite only ONE arduino is connected I have made a clean of all my port com, using this : http://blog.cognitioninfotech.com/2009/01/how-to-clear-or-reset-com-port.html But i steel CANT upload any sketch; i have the following answer from compilator:
avrdude: stk500_getsync(): not in sync: resp=0x30 avrdyde: stk500_disable(): protocol error, expect=0x14, resp=0x51
I was before using a duemillanove without any troubles, and with FTDI drivers.
Other thing important: the UNO appears in Windows Hardware panel, with its comport, but there is NO communication between apps and the UNO The firmata exe doesnt shows up anything.
the UNO is alive and works well on another laptov with seven ( upload and job)
ANy solution ?
