@Kevan et al.,

There is a very nice section in the Texas Instruments manual for the IC I am using which explains how to match correctly each of the three Hall sensor IC outputs with the corresponding coil winding. It does require a four channel oscilloscope but looks to ‘be faff-free’, though fairly technical.

Meanwhile in the world of digital slotcars things are nice and simple. AW and SW always are required to run in one direction (this is not universally true as per Kevan’s post below - thanks) and for in-line, direction depends on which side the crown gear is located. So two versions of the drive board required, one for clockwise and one for counter-clockwise rotation.

Anyway, I’m running ahead of myself here, seeing the new driver modules running motors in cars on tracks is a more immediate objective :)
