MCP41HV51

Hi all!

I've looked in the Wiki for an example of this component, but there isn't one. I just ordered a few, get them next week.

Does anyone have experience with these? I have tried to make a testprogram myself, am I on the right track, could someone have a look at my testprogram, please?

Hi Jorgen.
the MCP41XXX would refer to any three numbers after the 41.
Like wise with MCP41XX would refer to any two numbers after the 41.
As they are both different components, then they both will work differently.
The MCP41HV51 are a mixture of letters and numbers, therefore I would again assume it works differently.
You could try the MCP41XX, but I can't say if it will work or not?
If it does not work, then currently the MCP41HV51 is not supported.
If you can let me know, so we can look at adding the component for you.
If we need to add it, I don't have the board to test with, so I will need to order one.

One thing to note with your Flowchart.
You have got the debounce set to 5ms.
Debounce only works with the Switch functions and not with inputs.
If you want to use the debounce option then you will need to swap the inputs with ReadState function.
Also, don't forget the pulldown resistors for the switch
