**MIOS DIN/DOUT Pin Numbers**

Sometimes the pin numbers of special DINs or DOUTs can be specified in the
main.asm or setup_*.asm file of a MIOS application.

Examples:
<file>#define DEFAULT_MIDI_RX_LED 0x40        ; DOUT SR#9, pin D0
#define DEFAULT_MIDI_TX_LED 0x41        ; DOUT SR#9, pin D1</file>
or
<file>#define DEFAULT_DIN_MENU_EXEC         7       ; menu exec button assigned to DIN pin #7
#define DEFAULT_DIN_MENU_SNAPSHOT     6       ; menu snapshot button assigned to DIN pin #4
#define DEFAULT_DIN_MENU_RIGHT        5       ; NOT USED - overlayed by datawheel
#define DEFAULT_DIN_MENU_LEFT         4       ; NOT USED - overlayed by datawheel</file>
or
<file>       ;;        SR  Pin  Mode
        ENC_ENTRY  5,  0,  MIOS_ENC_MODE_NON_DETENTED   ; V-Pot 1
        ENC_ENTRY  5,  2,  MIOS_ENC_MODE_NON_DETENTED   ; V-Pot 2
        ENC_ENTRY  5,  4,  MIOS_ENC_MODE_NON_DETENTED   ; V-Pot 3
        ENC_ENTRY  5,  6,  MIOS_ENC_MODE_NON_DETENTED   ; V-Pot 4</file>

The following table should give you a quick overview over the numbers. Please
bear in mind that we are sometimes counting from 0, and sometimes from 1.

Means: sometimes the first pin or shiftregister has number 0, sometimes
it has number 1 - thats always an issue, because programmer mostly prefer
to count from 0, users want to count from 1 - it's a bit of a mess!
Forgive me! ;-)

In the meantime I've tried to make the setup more consistent. Shiftregisters
are always counted from 1, and pins are always counted from 0

---------------------------------------------------------------------------------------------------
**Important Note: for DIN shift registers, pins will be reflected on software-
level in reversed order for each shift register:**

D7 (hardware level) of the first shift register will be pin-number 0 (software level), not 7!\\
D0 (hardware level) of the second shift register will be pin-number 15 (sorware level), not 8!\\
The first shift register is for both DIN and DOUT the one that is closest to the core on hardware
level.

In the datasheets of the shift-register IC's, D0 is often labled A / QA, D7 is labled H / QH.

Note that this applies only for DIN's, NOT for DOUT's. For DOUT's D0 / A (hardware) will be the
lowest pin number in software. 

DIN chain hardware-level: CORE -> R1::qH -> R1::H -> R1 -> R1::G ..... R2::qH -> R2::H etc.\\
DOUT chain hardware-level: CORE -> R1::SER -> R1::A -> R1::B -> R1::C ..... R2::SER -> R2::A etc.

Ok, here the table:
