Hi!
First, I have to say, I am a learn-as-I-go-type. I have basic understandings of electronics but usually I start tinkering until I end up with a problem and then try to find a solution. This is why I am here now.
In my setup I have MP6500
's pins ENBL
through DIR
directly connected to an Arduino Nano’s digital pins D2
through D9
. This way I1
is connected to D6
which is a high frequency (~1Khz) PWM pin of the Nano. Also I set I2
to LOW
to enable current limiting via PWM.
My question: can I also use the coarse control still somehow with those pins being connected permanently?
My theory so far: In the section Current Limiting of MP6500
's description it says that for coarse control I1/2
need to be either low or high-impedance. As I said I am the learn-as-I-go type and high-impedance is a topic on the yet-to-understand-list but: documentation of Arduino digital pins says that when I put a pin to mode INPUT
it will also be in a high-impedance state. Is that what I have to do to set the correspoding I1/2
pin on MP6500
to what is given as Z
in the table of the description page?
Thanks and best regards
Manuel
