Using the ISP pins for BOTH led indicators and ISP

2005-01-20 by James Washer

I'm a bit tight on pin count, and would like to use the 3 ISP pins (MISO/MOSI/SCL) for LEDs. My plan is to tie the LEDs high, and then through resistors down to these pins.

I've "tested" this on an STK500 buy attaching the LED 10pin connector to the appropriate ports and have had no troubles.

I'm just looking for the "net wisdom" as to whether this is an acceptable practice.
