3-Bit BCD into integer

Hi,

I have ATC forced mode rotary switch it has 3-bit output these 3 outputs form a BCD number. My question is how to read these three binary inputs and output as integer.(for case switch)

you can write a simple component or you can use a already made one, if available.

Look at this

Hi,

I was thinking of writing a comporent. Any examples how to do this?

So it is this part?

case 'D': // BCD
i = 0;
pow = 1;
while (i < inst_sense){
if (i < inst_sense) d += sense(i) << (i % 4);
i++;
if (i < inst_sense) d += sense(i) << (i % 4);
i++;
if (i < inst_sense) d += sense(i) << (i % 4);
i++;
if (i < inst_sense) d += sense(i) << (i % 4);
i++;
p += d * pow;
pow *= 10;
d = 0;
}


I will try to understand it and borrow it to my code

This is not for carousel position. This is for manual moving of ATC arm. Machine has two selector switches for selecting which move to make. Ie. arm_in arm_out, arm etc. These switches output BCD. And if you remember i made a custom HAL component for ATC, and now I am adding this manual functionality in case of there is something wrong with ATC like chips between tool and arm preventing automatic tool change.
