Aprod:
I have the same problem mentioned above, installed the CH341 driver, Arduino IDE, rebooted the computer and hooked up the Arduino to the USB. It isn't listed in the Device Manager after repeating the install a few times. I'm looking to build my own electronic bike shifting setup, it's a shame this is holding me back!
Hi guys, did you solve problem with programing of VIS duino Uno r3?
I have the win7 x64 with the new CH341 driver ver. 3.4.2014.8.
If I choose the board UNO, COM3 (correct for me), I have the message:
avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x8c
Do I have to select the programmer? Which one? Or do something else?
Maybe the problem is with bootloader? If I follow the procedure from troubleshooting page and reset the board “The built-in L LED (which is connected to pin 13) should blink. If it doesn't, there may not be a bootloader on your board.” It doesn’t blink.
The watchdog works, low is blinking.
Hi. If I choose the Leonardo instead of UNO it looks better. I haven’t the red messages.
