Has anyone tried to get the N2ADR HL2 filter (http://james.ahlstrom.name/hl2filter/) to work with PoserSDR mRx PS?
The board uses a MPC23008 i2C chip as opposed to the PCA9555 chip described in pavel demins setup description: http://pavel-demin.github.io/red-pitaya ... ver-hpsdr/
The MPC23008 address lines are all tied to gnd. Not sure if these need to be reset to 0x21 or if the MPC23008 will be usable at all.
Thanks for any help.

Verified that the HL2 I2C commands are not compatible with the PCA9555 protocol.
Was able to get this to work by piggy backing two TPIC6B595 chips on top of the LPF board.
