How to migration from LPC1837 to LPC4337 ?

[jylee-kimin]

I have source code for LPC1837.

But i can not get LPC1837.

But I can get LPC4337.

LPC1837 and LPC4337 are compatible (pin-to-pin).

Thus I want to migrate source code from LPC1837 to LPC4337.

Can you advice how to migrate from LPC1837 to LPC4337 ?

Hi jylee-kimin 

These two parts are pin to pin replacement. and the source code are compatible as well.

You can use the same firmware, I have confirmed that you can use the same LPC1837 firmware with the LPC4337 MCU, I tested using the periph_blinky example from LPCOpen for the LPC1837 and flashed it to the LPC4337 and it worked without any problem. If your application created using LPCOpen, then the migration should be fast and the new features of the LPC4337 can be implemented easily.

Hope this helps,

Our firmware is generated by Keil uVision.

Is the firmware is compatible with LPC1837 and LPC4337 ?

If not, how to migrate from LPC1837 to LPC4337 ?
