programming ATTiny85 with arduino pro mini

gub11
gub11 over 10 years ago

I am using the arduino IDE and the arduino pro mini as an isp for my ATTiny85.  I am trying to test out the functionality of the tiny with a simple blink circuit, but first i obviously need to put the code on it.  I have all the wires going to and from the correct pins on my attiny and pro mini, but whenever i  upload to the attiny, with the pro min as an isp, i get the error unidentified device signature 0x0000000.

What should i do?

    are you using a FDTI serial converter?  the pro mini doesn't have a usb port so it requires a serial convert which is why I am confused.  Are you sure its a pro mini?

     

    If so, I assume the device signature error is a windows error when you plug in the USB?   Do you get this error without the ATTIny85 being hooked up?

    i am using an FTDI cable yes.  I only get the error when i am programming to the attiny with the arduino as an isp.  I can program my arduino pro mini over FTDI cable perfectly, but when i make the connection from the arduino to the attiny85 via breadboard, and try to upload to the tiny, i get a device signature error 0x0000000 while uploading to the tiny, which stops the upload.
