### Linux MCU step rate benchmark ###
The following configuration sequence is used on a Raspberry Pi:
```
allocate_oids count=3
config_stepper oid=0 step_pin=gpio2 dir_pin=gpio3 min_stop_interval=0 invert_step=0
config_stepper oid=1 step_pin=gpio4 dir_pin=gpio5 min_stop_interval=0 invert_step=0
config_stepper oid=2 step_pin=gpio6 dir_pin=gpio7 min_stop_interval=0 invert_step=0
finalize_config crc=0
```
The test was last run on commit `06437c58` with gcc version `gcc
(Raspbian 6.3.0-18+rpi1+deb9u1) 6.3.0 20170516` on a Raspberry Pi 3
(revision a22082).
