MIDIBox64E is a midi controlled based on MBHP/MIOS


DIN register allocation

Question from Dan aka Digineural:

I understand that the following is setting shift registers 5-8 to be used for encoders 1-16.

MIOS_ENC_PIN_TABLE 

 ;; encoders 1-16
 ;;        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
 ENC_ENTRY  6,  0,  MIOS_ENC_MODE_NON_DETENTED   ; V-Pot 5
 ENC_ENTRY  6,  2,  MIOS_ENC_MODE_NON_DETENTED   ; V-Pot 6
 ENC_ENTRY  6,  4,  MIOS_ENC_MODE_NON_DETENTED   ; V-Pot 7
 ENC_ENTRY  6,  6,  MIOS_ENC_MODE_NON_DETENTED   ; V-Pot 8
 ENC_ENTRY  7,  0,  MIOS_ENC_MODE_NON_DETENTED   ; V-Pot 9
 ENC_ENTRY  7,  2,  MIOS_ENC_MODE_NON_DETENTED   ; V-Pot 10
 ENC_ENTRY  7,  4,  MIOS_ENC_MODE_NON_DETENTED   ; V-Pot 11
 ENC_ENTRY  7,  6,  MIOS_ENC_MODE_NON_DETENTED   ; V-Pot 12
 ENC_ENTRY  8,  0,  MIOS_ENC_MODE_NON_DETENTED   ; V-Pot 13
 ENC_ENTRY  8,  2,  MIOS_ENC_MODE_NON_DETENTED   ; V-Pot 14
 ENC_ENTRY  8,  4,  MIOS_ENC_MODE_NON_DETENTED   ; V-Pot 15
 ENC_ENTRY  8,  6,  MIOS_ENC_MODE_NON_DETENTED   ; V-Pot 16

However I'm not quite sure what is being defined here

#define DEFAULT_DIN_SR_PIN_01_08 2
#define DEFAULT_DIN_SR_PIN_09_16 3
#define DEFAULT_DIN_SR_PIN_17_24 1
#define DEFAULT_DIN_SR_PIN_25_32 4
#define DEFAULT_DIN_SR_PIN_33_40 8
#define DEFAULT_DIN_SR_PIN_41_48 10
#define DEFAULT_DIN_SR_PIN_49_56 11
#define DEFAULT_DIN_SR_PIN_57_64 12

Answer: MB64E supports up to 64 button functions, and they are assiged to 8 shift registers. With the DEFAULT_DIN_SR_* settings you can change the mapping. This is important, if the appr. shift registers are already allocated by encoders (defined in mios_tables.inc) - if this is the case, change the DEFAULT_DIN_SR_* values to unused shift register numbers.
