The new MBHP_DIO_MATRIX module combines two DIN and two DOUT registers to simplify the wiring to button/keyboard matrices.
It has been mainly created for the upcoming MIDIbox KB project, therefore J3 and J4 (input/output pins) are (almost) 1:1 compatible to most Fatar keyboards.
But the module is also useful for other purposes, e.g. for matrices connected to MIDIO128 or simply whenever only two DIN/DOUT shift registers are required for a project.
Something wrong is in mbhp_ainser64_v1.brd file. Eagle noticed me "invalid data in file" the structure looks like "web page" not an eagle file.
The same problem is in mbhp_dio_matrix_v1.brd file.
