I have the standard Arduino IDE. I have several cores installed, including ATTINY CORE by SpenceKonde. This core included a programmer titled "USBTinyISP ATTINY CORE which I have previously used successfully with a sparkfun ATTiny85 programmer. Since this was working I think I don't need to have WinAVR but I did install it. That is my experience with ATTiny programming by USBTinyISP programmer.
I would like to now use the AF programmer as it is a better design. I tried to use the provided USBTinyISP programmer, as well as the ATTINY CORE USBTINYISP programmer options in the tools menu. Both give the same error.
I installed a different package of AVR tools from AVR-GCC 7.2.0 for Windows 32 and 64 bit
http://blog.zakkemble.co.uk/avr-gcc-builds/ but it's in a separate directory. It also include AVRDUDE. I tried with it added to Windows path and without, same result.
Since I can program chips via USBTinyISP programmer option in the IDE using the SparkFun USBTiny programmer board I believe I should be able to use the AF programmer. Per the tutorial
https://learn.adafruit.com/usbtinyisp/h ... ll#use-it/ when I give the AVRDUDE line command
I get the response that the programmer is connected to the PC but not to the chip as expected and the red led flashes briefly once. I think it's an IDE / AVRDUDE issue but not certain.
The AF device is listed in Device Manager and properties indicates it is working properly. The UNO and Metro are powered and light up when the 6 pin connector is attached. I installed the AF drivers again and same result. Any insight is appreciated.
