I need an instrument that can monitor two signals from a stepper motor controller.
Namely STEP and DIR.
For the STEP signal I want to monitor the step pulse length and time between pulses recording min and max.
For the DIR signal I want to record the minimum setup/hold time in relation to rising edge of the STEP pulse.
The STEP signal frequency is max 150 kHz and the minimum pulse length (both more or less
guaranteed by design because it is software generated) is 500 nsec.
Required accuracy is 2 usec.
I happen to have Parallax Propeller dev kit that I've never used so I figure out, maybe this is something that
could be relatively easily implemented on it.
Is this feasible?
Where should I start?
Pointers to 'closest similar' ready made project to get me started?
I've never programmed Propeller but have close to 40 years of experience in embedded stuff with
all the usual suspect CPUs working with assembler and C.
Any comments welcome.
