The test was last run on commit `1487f8a2` with gcc version
`arm-none-eabi-gcc (Fedora 7.4.0-1.fc30) 7.4.0`. The best single
stepper result is `SET ticks 757`, the best dual stepper result is
`SET ticks 761`, the best three stepper result is `SET ticks 757`, and
the best four stepper result is `SET ticks 767`.
The test was last run on commit `c380d463` with gcc version
`arm-none-eabi-gcc (Fedora 7.4.0-1.fc30) 7.4.0`. For the STM32F446 the
best single stepper result is `SET ticks 757`, the best dual stepper
result is `SET ticks 761`, the best three stepper result is `SET ticks
757`, and the best four stepper result is `SET ticks 767`. The
STM32F407 results were obtained by running an STM32F407 binary on an
STM32F446 (and thus using a 168Mhz clock) - the best single stepper
result is `SET ticks 709`, the best dual stepper result is `SET ticks
714`, the best three stepper result is `SET ticks 709`, and the best
four stepper result is `SET ticks 729`.
