in the prog u listed above, i dont see any
result is, that the pic will keep resetting itself in a loop
after the watchdog is reached his time , after xxx ms
when programming in picallw, disable watchdog timer !
that is a mistake very...
i think that building/designing your own inverter is not that simple
and it is not worth a try because of the costs...
inverter Lenze type 8200 series or ev82 vector series costs
about 200 euro and have a lot of feutures
input = 230vac
output 3 phase
almost all is...
i finally uploadet an image of quadrature encoder.
hope this image is clearing up a bit.
( i'ts just a scratch draw of principle )
about the problem u just having...
cant say mutch, because of too less info on whole...
normally 12 bit is at the edge for a scale of 1000 (for na values).
-did u decouple the i/v output voltage with small ceramic condenser ?
-are your measuring wires not too long ?
-try to 'transport' that signal with a thin coax cable (schield grounded 1 s.)
-decouple your i/v...
hey guys, stick to the point
when the man wants some info,
just try to help and dont explain him the optical mouse technology.
the question was about an dc motor and encoder.
well, about the fotocells, they are fitted in one housing
and 'looks' like 1 thing that supposed to be the...
if u go to the link i gave before, u'll understand....
u have 2 sqware waves,
the 2 waves are shifted 90° (mechanicly, by moving the 1st fotocel
1/4 wave further than the 2nd fotocel)
if u see this picture (imaginary) in front of you....
than u can say...
if upgoing edge 1st fotocel...
actually, the mouse have 2 axes (x and y)
if u remove the ball, u'll see 2 axes and 1 or 2 wheels to close
up the ball.
the encoder is a quadrature encoder type like used un
feedback motors like servo...(only dubble made)
for further encoder info (details ) see link below...
try this link
think there u'll find something suitable
something else u can try; (depends on witch range u desire)
an video modulator ( everyone has an old broken VCR somewhere
in the howse, atleast, i dont throw sutch things away)
pic16877 in circuit programming
using low voltage mode, is the same as
losing the pin rB3 i/o. so, i dont like it either....
otherwise, using standard high voltage mode
could be done, when u use a voltage switcher on the mclr pin, combined with a
analog switch 4066 on the rb7, rb6 pin.
