atmega32u4 with Crystalfontz 632 v2.4

I am using an Atmega32u4 to communicate with my LCD screen (Crystalfontz 632 v2.4), the problem is that I only have the sda(port d, bit 1) and scl(port d, bit 0) pins available to me. I have tried using the software serial library but it interrupts communication with my other serial ports. Is there another solution for this problem?
