Hi

For my project I need to use a 6 way position curson for driving an ain.

All AIN input need to have a pot and a pot is a variable resistor so I thought that if I put 6 resistors in the 6 pin of the curson with value 0,2.2k,3,9k,5,6k,8,2k,10k I i'll obtain my result. But my problem is with the connection.

Pots have 3 pin and my "modified 6 position curson have 2 pin, the first is the common, and the second is the other pin connected to all resistors that can be selected with the cursor; what about the third pin?

Help's useful! Thank you!

Hi Andrea,

is this a switch which provides a common pin, which can be select between 6 terminals?

Then you could connect it the same way like shown in this schematic:

The resistors are connected between the terminals, and the common pin is connected to the analog input.

Best Regards, Thorsten.

Ok, I understand!

Now it's clear...it's a sort of simulaton of a pot but done with resistors!

Thank you very much, another time!!!

I have another question regarding an additional midi in port: I have seen the midimerger project and also the IIC midi that provide additional midi in for the midibox and I have seen that both use the RA4 port of the PIC...this is my question: If I use this port of my midibox64 for driving a 6n138 ecc connected to another midiin port does it work or I need another PIC for doing this?

Bye

... better start a new thread (... as long as it has completely nothing to do with your first question). - Makes it much easier for other users to search for.
