Hi Jordan Halgunseth,
You must change the head file to LPC1114, because LPC11U14 and LPC1114 have some difference. The register address also have difference.
Please change the head file, then check the driver, you should better use the LPC1114 driver.
About the LPC1114 driver, you can refer to lpcopen code:
LPCOpen Software for LPC11XX|NXP
Have a great day,
Kerry
