LPC55xx API

[Lor75]

Hello,

for a new project I want to use LPC550x microcontroller with IAR Embedded Workbench: in the past I have used other LPC MCU (LPC1317, LPC1788, LPC1788)

Now i read everywhere that some functions can be managed only by using API but I don't understand how to use them; are these function available only with MCUXPRESSO?

I would like to avoid API and write my own code but I don't fine the C code of these API. For example CAP BANK for oscillators are only documented with API so if I don't use API I can't use these CAP BANK. Is it correct?

I have a big confusion in my mind about this.

Can anyone help me? It's for my job

Best regards.

Hello @Lor75 

For newer NXP MCUs, including the LPC55xx series, we recommend using the MCUXpresso SDK drivers, which include both APIs and source code.

You can download the SDK from:

For detailed instructions, please refer to:

Additionally, the LPC55xx series is supported by MCUXpresso IDE, which is free to use with no restrictions on functionality or code size.

You can download MCUXpresso IDE from:

If still have any question, please feel free to contact me. Thank you.
