Coding in assembly for LPC812

SunTzun — Sun, 21 May 2023 11:31:37 GMT

Hello. Is there a route to write code for LPC812 fully in assembly without any automatied compilers?

Preferably, if this can be done through an IDE without manually confuguring the linker.

Yes, you certainly can do this using the GNU as (assembler) (https://en.wikipedia.org/wiki/GNU_Assembler). But I still would advocate that you are going to have the ld in the mix, as it simplifies all the memory mappings.

Do any guides or examples for assembly coding for this microcontroller exist?

Not for LPC812 (don't have that one), but for LPC845:

I hope this helps,
