### RP2040 step rate benchmark ###
The following configuration sequence is used on the RP2040:
```
allocate_oids count=4
config_stepper oid=0 step_pin=gpio25 dir_pin=gpio3 invert_step=0
config_stepper oid=1 step_pin=gpio26 dir_pin=gpio4 invert_step=0
config_stepper oid=2 step_pin=gpio27 dir_pin=gpio5 invert_step=0
config_stepper oid=3 step_pin=gpio28 dir_pin=gpio6 invert_step=0
finalize_config crc=0
```
The test was last run on commit `c5667193` with gcc version
`arm-none-eabi-gcc (Fedora 10.2.0-4.fc34) 10.2.0` on a Raspberry Pi
Pico board.
