I know the MBHP CORE LPC17 build guide mentions this, but I just wanted to confirm.

http://www.ucapps.de...core_lpc17.html
The pinning of the 2x8 LCD connectors J15A and J15B is mirrored to simplify the cabling of common 2x20 and 2x40 displays (and partly due to historical reasons - it's originated from the so called "UltraPCB").
Note also that in difference to the MBHP_CORE_STM32 module, the J15 ports have been rotaed by 180 degrees! But the polarity is the same, which means that you can re-use the LCD cables which you made for the MBHP_CORE_STM32 module.

What exact orientation does my J15 header go in? Pin 1 is bottom right on the PCB from SmashTV, but the header itself says Pin 1 is bottom left if the keying is facing down. See picture below:

Almost done with my first core!!!

Pin 1 of J15 (Vs) goes to Pin 1 of the LCD (pin is typically named Vss)

Awesome, that makes perfect sense. Thanks TK!

Just need to order a screen and attach my ARM board and I am complete!
