in http://www.ucapps.de/mios_c_set_dout.html it says

  // only one DOUTX4 module is connected

  // the maximum value is 16 (-> 128 digital outputs)

  MIOS_SRIO_NumberSet(16);

}

but i think it should be

MIOS_SRIO_NumberSet(4);

No ;)

the MIDIO128 supports 128 outputs = 16 ICs = 4 DOUTX4 modules.

That means one DOUTx4 module has 4 ShiftRegisters:

128 Pins / 16 SRs = 8 DOUT pins per SR

So if you intend to use 32 DOUTs (= all pins of one DOUTx4 board)' date=' you need to call:

32 Pins / 8 pin-per-SR = 4 SRs =>

[tt']MIOS_SRIO_NumberSet(4)[/tt]

mmm, this is what i mean

// only one DOUTX4 module is connected

???

[audiocommander]

okay, got the point :)

besides the fact you changed your original posting from the wrong SR_Set(1) to the now correct SR_Set(4) -  :P

the page sais that a maximum of 16 SRs can be chained and the example is showing how to connect 128 LEDs; so the statement is right, just the comment is not clear, because you need four DOUTx4 modules to connect 128 LEDs.

yep shame on me i can t believe i haven t stated that i ve edited the post, sorry

it took me a little while to understand, well to read, cause it is written, that we are talking about pins pairs.It s new to me cause i ve always seen either the pins counted 0,1,2,3,etc or the SR 1,2,3,etc.

so the statement is right, just the comment is not clear,

sorry to insist but i think that the comment is wrong (not unclear) or that the statement is not consistent with the comment.

so, for the record, the right comment would be:

  // only one DOUTX4 module is connected

  // four DOUTX4 modules connected

  // the maximum value is 16 (-> 128 digital outputs)

  MIOS_SRIO_NumberSet(16);

:)

yep

Changed the comment:

  // Up to 4 DOUTX4 modules (=16 shift registers = 128 digital outputs) can be connected
  // set the maximum number here - it doesn't really hurt!
  MIOS_SRIO_NumberSet(16);

LOL jimp is bugfight... Or should I say, bugfight is the Midiboxer Formerly Known as Jimp. I think he used to go by something he called the 'love symbol', it looked like this:
