    Hi chaps

    Does this group also include the Raspberry rp2040/rp2350 as well?

    I'd like to think so, but it's somewhat niche (Baremetal that is)
    however...

    like to know how to do it baremetal with ARM thumb assembly.

    ... my use is the RISC-V cores in the rp2350, so bare metal RISC-V
    asembly.... But the principle for programming the PWM generators
    is more or less the same from eith CPU, so I understand, but it's
    something I've not gotten round to.

    I'd suggest to have a look at the manual and SDK and see how to do it
    from C then hand translate the C code into ASM...
