Hi,

I tried to find information about the pinout of the logic analyzer connector, but documentation is a bit weak at the moment :) and I fully understand why. Could somebody please supply the pinout or point me to a document containing it? That would be great.

Best

Let's see if I can give you something until we release a manual

   1:8  Logic Analyser<7:0>
     9  External Trigger
    10  GND
    11  AWG output
    12  GND
 13:16  Digital out <0:3> 

Does that work for you?

Hi,

thank you for the pinout. I played around with the logic analyzer and have two comments:

  • pin 1...8 are the LA inputs, but in reverse (7...0), right?
  • if I add an I2C analyzer, the white graph on light grey background is completely unreadable (although I was happy to get it running!)

Could you please change the default color to black and/or add an option to change the color?

Please correct the documentation:
The pins seem to be reversed:

I have to admit our output suffered a bit during the holiday period.. I quickly changed updated the information.

Please, review the pinout documentation in the Wiki.

For Flat ribbon connectors, the numbering starts with "1" on the right side where the nose is, "2" is on the right side of the side opposed to the nose and so on.

The way the wiki doc numbers is contradicting those both rules. And even with this unconventional numbering, the channels are located wrong. And as GND is not symetrical, I fear to connect the part.
