Hi all!

Thanks a lot for your help.

@aarg: What I doing it reading CAN-Bus Data from a Car. I get 8 * 8Bytes of Data, saved in an Array "rx_frame.dada.u8"

So in total, I receive 64 Bits of information.

These Bits could represent the state of 64 actuators in terms of "on/off --> 0/1.

Usually though the 64Bits represent measurement Values of some sort. So, for instance we could receive a message :

`HEX: A7 03 B4 9D 00 BB 07 7D `

This would be in BIN

`10100111 00000011 10110100 10011101 00000000 10111011 00000111 01111101`

Now lets suspect there are 2 known signals in this message.

- 1 is an On/Off state

- 1 represents the speed of the car

The CAN Database could say:

Signal 1: Startbit 0, Length 1

Signal 2: Startbit 11, Length 9

For Signal1 I would need to take the first Digit of the Binary - pretty simple.

For Signal2 I would need to take "000011 10110", and convert this to a Decimal Number, multiply with a Faktor and Offset it. If there was no Faktor or Offset the correlating DEC would be 118.

So, for what I see I have to accomplish the following tasks:

1. Take all the Data of the Array "rx_frame.dada.u8" and put it together in one variable.

2. I need to somehow sort out the Bits I need (--> Bitshifting?) into a separate variable

3. Convert the picked out bits to a decimal value.

4. Faktor and Offset the value.

3 and 4 is clear - 1/2 not yet.

Hope I could explain what I am trying to do...

Very thankful for any input!
