Error: could not find USBtiny device (0x1781/0xc9f)
Posted: Tue Jul 26, 2011 7:16 pm
I am having trouble connecting to my Pocket AVR Programmer.
I am using an Atmega328p-pu on Windows 7 64 with WinAVR. I am fairly certain I have everything plugged up correctly (my multimeter can detect power when the programmer is connected to my computer). I have tried switching MISO and MOSI. I downloaded the driver from the SparkFun product catalog page and have since rebooted my computer.
I get the following error message when I attempt to program my avr:
Please instruct me how to download programs to my AVR. I apologize I am unable to upload photographs of my set-up (The "Img" button in the "Post a new topic" editor requires a URI and the "Upload attachment" box only allows attachments of a size less than one megabyte.)
Thank you in advance.
P.S. What do MISO, MOSI, and SCK stand for?
