I am trying to use the Pocket AVR programmer (USBTiny) to program a ATMega2560 but I am not able to upload anything because the Arduino IDE does not it in the serial boards. I am using a Retina Mac with OS X 10.8 - I also tried a MacMini with 10.9 with the same results.
When I plug the USBTiny in then the “power” and “D-” LEDs light up. I also tried the avrdude:
avrdude -c usbtiny -p t2313
avrdude: AVR device initialized and ready to accept instructions
Reading | ################################################## | 100% 0.00s
avrdude: Device signature = 0x1e950f
avrdude: Expected signature for ATtiny2313 is 1E 91 0A
Double check chip, or use -F to override this check.
avrdude done. Thank you.
After that command also the “stat1” LED is lit. But I still don’t see it in the serial board section. Also I dont what to do about “Expected signature for ATtiny2313 is 1E 91 0A”.
Is the Pocket AVR programmer hardware OK? I bought already a different USBTiny (torobot) which did not work at all.
Any suggestions how to get programmer listed in the serial board section?
I have attached a photo of the connected boards. If that message reports indeed a mega2560 than that is wrong as well. I have an Arduino Uno connected.
I am already googling around for days and tried all hints. I even bought a USB2 hub, different cables and installed “FTDIUSBSerialDriver_v2_2_18.dmg” with no effect. So far I spend more than $100 on 3 different USBTiny, USB HUB, and various USB cables… This is really frustrating.
How does anyone with a mac use the USBTiny with the Aduino IDE?
I tried your suggestion and my Uno is now connected via the AVR Programmer to a PC. I am running XP SP3 from 2002 on a Virtual PC on a mac and I get a grayed out port menu as well. The Arduino IDE is v 1.0.5.
I installed the “usbtinyISP” win32 driver v1.12 from adafruit website but the usbtinyISP does not get listed as a port.
