@micropython.asm_thumb error

[GKellu]

Hi everyone, I try to use following code on pi pico with micropython v1.19.1:

@micropython.asm_thumb
def asm_add(r0, r1):
add(r0, r0, r1)

Code is from latest documentation on micropython. I get this error:

Traceback (most recent call last):
File "", line 3, in asm_add
SyntaxError: expecting an assembler instruction

I get this error on every code tested from documentation. I have tested it on micropython v1.17 with same result.
Please help me how to use inline assembler on pi pico with micropython.

Maybe you try the code with the actual nightly build of the firmware. If I run your example with that, I get no error.

@micropython.asm_thumb
def asm_add(r0, r1):
    add(r0, r0, r1)

print(asm_add(1,11))

Try to use it without Thonny, like with a simple terminal emulator. Or put the script in a local file like asmtest.py and run:

mpremote run asmtest.py

Thonny has quite a bit of magic under the hood, which sometimes is helpful, sometimes a pain. So if anything strange happens when using Thonny, try without Thonny.

Please use proper formatting when posting code. You can get that by enclosing the code with lines containing three backticks: ```

Thank you Robert, The problem is Thony IDE. Can you recommend other free IDE to use with Windows?

[robert-hh]

Actually not, sorry. I do not use IDEs with Micropython boards. I just use a local Editor and simple tools like mpremote, picocom, ftp.

Thank you.
