Quadrature Inputs [11 Articles]
Paul Johnson - Mar 8 2003
I'm surprised, given the number of embedded applications involving motor
control or data capture, that almost no micros out there support quadrature
input. On our p... 
9S12DG256 Quadrature Encoder Support. [14 Articles]
John Dammeyer - May 31 2004
Hi all,
Lately whenever I've had to do quadrature support I must admit I've been kind of spoiled. In the
past we've used an LSI chip that takes quad A,B in and p... Motion Control Algorithms [7 Articles]
Allen, Nick - May 6 2003
Does anyone know of motion control firmware,
preferably written in C? Would want it to
include full PID algorithm, interface to
quadrature encoder, and interfac... OT Hybrid Controllers [5 Articles]
Shayne Rich - Jun 21 2005
Hi, I know this is off-topic, but is there a group dedicated to the 56F
family of hybrid controller?
If there is not, has anyone used them? I'm interested in them b... Encoder Integration [3 Articles]
Paul Williams - Jul 31 2006
I am having trouble integrating an encoder into my code for a MC9S12D64. I
am using ICC12 and am using a combination of C and assembly.
I have tried using a timer interrupt with... Input Capture and Output Compare for MC9S12DP256
yawjiun_84 - Nov 18 2007
Hi,
Can I know where I can get the detail information on the basic steps
to write program for the interrupt in C? Any sample code as a reference?
Basically, I will use Outpu... Re: need a P&E GAL for CablePPC....want to trade?
timbomcnuckle - Jun 27 2007
Thanks for that! I'll have to go back and re-check them both out! I am
fairly sure that the issue is the GAL though,, as I have swapped out
both ribbon cables and GAL's on each a... Re: Incremental rotary sensor (motor) as input to HCS12 [2 Articles]
tonalbuilder2002 - Apr 4 2005
Or, you could connect each phase of the quadrature encoder to 2 input
lines, one programmed for a rising edge interrupt, the other for a
falling edge interrupt.
