*** Timings of the m8driver *** These timings are based on a crystal frequency of 16MHz. Name | Value in nanoseconds | Description =============================================================================== steplow | 250 | Minimum length of a step "low" pulse. | | stephigh | 250 | Minimum length of a step "high" pulse. | | stepcalc | 2000 | Time required to process one step. | | Time starts after detection of "high" pulse. | | dirsetup | 0 | Minimum spacing between a direction | | change and a step pulse. | | dirhold | 500 | Minimum time between a step "high" edge | | and a subsequent direction change (for the next step).
