Hi. See attached diagram.
I am trying to interface a new AVR device with an existing AVR device via Two-wire Interface (aka twi, i2c). The existing device uses PD0/1 as GPIO but I can re-route the switches that are currently on those lines since they, conveniently, are attached by connector. I realize if I remove the resistors and capacitors and make the connection at "connect points" that I'm in business, but ideally , I'd like to not have to physically modify the existing device at all.
Can you think of any way to do so? Is there any sort of electronic trick I can pull-off in the new device to "negate" the effects of those components? I doubt it, but I know that I know so little that I better ask!
Thanks for any suggestions.
ps. I neglected to show it in the ediagram, but the "loose" ends of those caps are connected to GND.
