MPLABXpress: no hardware i2c channel?

Picked up the MPLABXpress board to play with the FC7 template and USB boot loader. Seems nice for the price.

I want to add an i2c LCD display. But unlike other PIC chips, the LCD display doesn't seem to offer a hardware i2c channel for the MPBLAXpress 16F18855.

Is that the case or am I missing something in the setup process? Or does the component need to be re-created for each processor type?

Thanks...

I think this is because we do not yet support hardware I2C on the PIC16F18855
The software I2C should be usable.

OK, thanks for the info. I am impressed by the FC7 / Xpress board integration, just was wondering if there is more to come in terms of chip support. I'm sure it's a never-ending job for you guys to keep up with all the hardware options.

It certainly is a challenge, with new chips being released all the time and new features being added.

I've added a bit of an explanation of the I2C hardware problem here.
