  Sorry guys, I've actually found the fix. One really need to add the SPI1.setup() line, and by trial and error I've discovered that the 3 below parameters are the mandatory ones:

  SPI1.setup({sck:A5, miso:A6, mosi:A7});
  SPI1.send([0x20,0b01000111], E3);

  With them it works all the time, without it only works some times... (which is really strange :) )

  Hi guys,
  I don't know if anybody still follows this thread, but I'm having a very similar problem with the 1v70 on this same board.
  The difference is that sometimes, after un-powering and re-connecting the board (most often I have to do it several times) I do get correct data.
  BUT, as soon as I re-run the "SPI1.send([0x20,0b01000111], E3);" line I keep getting 0 OR 255 as values.

  Thank you for your help,
  Dan
