I have started the process of porting my CO2-laser driver from MSP430 to Tiva C and I am switching to an algorithm based approach for the stepper acceleration/deceleration. As part of testing I have (re)written an implementation of David Austins algorithm as documented here: http://www.embedded.com/design/mcus-processors-and-socs/4006438/Generate-stepper-motor-speed-profiles-in-real-time The test code may be of use for others so here it is. PA7: direction PF1: step pulse From what I can glean from my scope the interrupt handler executes in about 2us - so can be used for high p
