* stepper: Minor code tweak - remove unneeded parenthesisKevin O'Connor2025-05-091-1/+1
| | | | Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper: Minor code reorg - remove unneeded HAVE_OPTIMIZED_PATH definitionKevin O'Connor2025-05-091-8/+7
| | | | | | | Make it more clear that stepper_load_next() has three separate code paths - one for each of the optimized stepper_event_X() functions. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper: Also ensure minimum time after dir change and next stepKevin O'Connor2025-05-091-3/+11
| | | | | | | | | In practice the host will not schedule any steps immediately after a direction change (due to acceleration limits and the host "step+dir+step filter"). However, there is also no harm in enforcing a minimum duration in the mcu. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper: Ensure minimum time between step pin and dir pin changeKevin O'Connor2025-05-091-0/+4
| | | | | | | | | | | | | | | Commit 8faed8d9 made it possible to utilize stepper_event_full() while utilizing tmc "step on both edges" optimation. That commit would ensure a minimum step pulse duration, but it did not ensure a minimum duration between step pin and dir pin changes. Commits 0d27195f and 554ae78d optimized the gpio handling on stm32h7 chips, which could potentially cause a very small amount of time between step pin and dir pin changes. Enforce a minimum time after a step pin update before updating the dir pin. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper: Move timer checks from stepper_event_full() to stepper_load_next()Kevin O'Connor2025-05-091-10/+16
| | | | | | | This simplifies the stepper_event_full() and makes it easier to implement more complex checks. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stepper: Free stepper_move struct near top of stepper_load_next()Kevin O'Connor2025-05-091-18/+26
| | | | | | | | Move up the freeing of the stepper_move struct and setting of s->position in stepper_load_next(). This simplifies the code and will make it easier to add more logic to this function. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stm32: Run stm32h723 at 520MhzKevin O'Connor2025-05-022-2/+4

* stm32: Use 12Mhz nominal internal clock in stm32f0_i2c.cKevin O'Connor2025-05-021-9/+9
| | | | | | | Increase the internal nominal clock from 8Mhz to 12Mhz - this improves support for higher chip frequencies. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* neopixel: Round up in nsecs_to_ticks()Kevin O'Connor2025-04-281-1/+1
| | | | | | | The rp2040 operates at a fast internal clock with a relatively slow external timer and dividing down could result in a too small delay. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* stm32: Set the PLL frequency equal to CONFIG_CLOCK_FREQ on stm32h723Kevin O'Connor2025-04-281-1/+1
| | | | | | | | There is no reason to use a higher internal PLL frequency. This change also makes it possible to enable higher clock frequencies on the stm32h723. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
