Hi, I have just returned to the Arduino world and am trying to use my Microview.

When I plug it in to the USB programmer and then connect that to a USB port on my PC (a Dell laptop with Win 7) I get the Hello World displayed with a blinking object (space invader?) below it, but if I try any of the demos using a jumper from gnd to pin 5 for instance I receive no response.

I have also tried powering the microview from a breadboard power supply both with and without the USB programmer.

If I try to upload an example sketch I get the following error message

avrdude: ser\_open(): can’t open device “\.\COM1”: The system cannot find the file specified.

Looking at the “Tools” menu in the IDE the board is shown as “Arduino/Genuini Uno” and the Port is shown as Serial port Com8.

Any assistance would be gratefully received.

Regards Zaq

It looks like _avrdude_ is expecting the programmer to be on COM1 but it’s on COM8. Have you selected COM8 as the port in the Arduino IDE?

I don’t know why COM8 is selected and I don’t see any option to change it.
