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
DIR directly connected to an Arduino Nano’s digital pins
D9. This way
I1 is connected to
D6 which is a high frequency (~1Khz) PWM pin of the Nano. Also I set
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
