Track group Leds are dual coulor? 2 more questions on changing din/out pinning

MIDIbox SEQ

Hi Forum!

Finally i really have time to work on my seq, finally i´m getting somewhere.

Right now i´m soldering buttons and leds.

To match to my hardware i have decidet to use my own definition for the buttons and leds.

First of all: I can´t programm and i feel it´s really great how the setup.asm file is commented. Think i have understood almost everything, only few questions remain (sorry if these are answered elswhere, i didn´t really find it here or in the wiki):

LED_GROUP1 EQU (((11  -1)<<3)+    0) ; OPTIONAL! see CHANGELOG.txt

LED_GROUP2 EQU (((11  -1)<<3)+    2) ; assigned to pin 2 due to DUO LED

LED_GROUP3 EQU (((11  -1)<<3)+    4) ; assigned to pin 4 due to DUO LED

LED_GROUP4 EQU (((11  -1)<<3)+    6) ; assigned to pin 6 due to DUO LED

I thought the track group buttons are normal leds. Really confused now.

Next thing, If for example i change the dout pinning so that the play led is on pin 1 of shift register nr5 than this will of course interact witch the definition for the bpm display.

What do i do? Simply this?

; === BPM digits ===

;

; set to 1 or 2 to enable the 3 optional BPM digits

;    0: BPM digits disabled

;    1: digits with common cathode

;    2: digits with common anode

#define DEFAULT_BPM_DIGITS_ENABLED 0

;

; define the shift register to which the segments are connected (0=disabled)

#define DEFAULT_BPM_DIGITS_SEGMENTS 0

; define the shift register to which the common pins (cathodes or anodes) are connected (0=disabled)

#define DEFAULT_BPM_DIGITS_COMMON 0

;

3rd question:

If a din pin that has a function in the original design will be unused in my setup, what do i have to do?

Eg, in my design pin D4,5,6 of register 4 will be unused.

I will adjust this entry to my need anyway:

DIN_ENTRY SEQ_BUTTON_Solo, 4, 4

DIN_ENTRY SEQ_BUTTON_Fast, 4, 5

DIN_ENTRY SEQ_BUTTON_All, 4, 6

After that D4,5,6 will not be definened any more. Done?

Thanks, Jens

Looks like i solved this one myself, wasn´t that hard. If there is a button in the design that i don´t use than i just set it to sr 0.

Still not sure why the track group leds are supposed to be dual colour.

I connected dual colour LEDs to the DOUT register, but only use the green LEDs.

hi TK, i got the same “issue” with the dual color setup…i tried to use normal leds, they are reacting very strange, like , when i switch to track 3 then 3 leds lit up, T4-> 2 lit up…

is there a way and a “how to” to change the behaviour of the pinnings , so that they will behave like all other leds?..just to put single ones on there?..since im no programmer, but i learn

every day a bit more :wink:

Open the setup_mbseq_v3.asm file, and change following lines:

LED_GROUP1      EQU     (((11   -1)<<3)+    0) ; OPTIONAL! see CHANGELOG.txt
LED_GROUP2      EQU     (((11   -1)<<3)+    2) ; assigned to pin 2 due to DUO LED
LED_GROUP3      EQU     (((11   -1)<<3)+    4) ; assigned to pin 4 due to DUO LED
LED_GROUP4      EQU     (((11   -1)<<3)+    6) ; assigned to pin 6 due to DUO LED
[/code]


to:
[code]  
LED\_GROUP1&nbsp; &nbsp; &nbsp; EQU&nbsp; &nbsp; &nbsp;(((11&nbsp; &nbsp;-1)\<\<3)+&nbsp; &nbsp; 0) ; OPTIONAL! see CHANGELOG.txt  
LED\_GROUP2&nbsp; &nbsp; &nbsp; EQU&nbsp; &nbsp; &nbsp;(((11&nbsp; &nbsp;-1)\<\<3)+&nbsp; &nbsp; 1) ; assigned to pin 1 for nuke's HW  
LED\_GROUP3&nbsp; &nbsp; &nbsp; EQU&nbsp; &nbsp; &nbsp;(((11&nbsp; &nbsp;-1)\<\<3)+&nbsp; &nbsp; 2) ; assigned to pin 2 for nuke's HW  
LED\_GROUP4&nbsp; &nbsp; &nbsp; EQU&nbsp; &nbsp; &nbsp;(((11&nbsp; &nbsp;-1)\<\<3)+&nbsp; &nbsp; 3) ; assigned to pin 3 for nuke's HW

thereareafter build a new .hex file and upload it

Best Regards, Thorstem.

hey thanx a lot…but…did this allready…somehow

in my setup.asm it looks like (5 is the last Dout SR in my chain):

LED_GROUP1      EQU    (((5  -1)<<3)+    7) ;

LED_GROUP2      EQU    (((5  -1)<<3)+    0) ;

LED_GROUP3      EQU    (((5  -1)<<3)+    5) ;

LED_GROUP4      EQU    (((5  -1)<<3)+    6) ;

LED_TRACK1      EQU    (((5  -1)<<3)+    2) ;

LED_TRACK2      EQU    (((5  -1)<<3)+    1) ;

LED_TRACK3      EQU    (((5  -1)<<3)+    3) ;

LED_TRACK4      EQU    (((5  -1)<<3)+    4) ;

…due to my pcb layout…so i guess it must be something else…

what does the max SR (1-16) meant to do?..since i got 17 SRs in total…5 DOUTs and 12 DINs

should it be 12 ´cause the longest chain is 12? or 17 (in total)?

maybe its only a terminition thing…i´ll go try it out…post you afterwards… :wink:

There are two shift register (SR) chains, one for “DIN SRs” (each MBHP_DINX4 module is stuffed with 4 SRs), and one for the “DOUT SRs” (each MBHP_DOUTX4 module is stuffed with 4 SRs). Sometimes they are also called SRIO chains (Shift Register Input/Output chains)

SRs are counted from 1, the first SR is the register which is directly connected to the core.

Hope this helps. Here a table which could help even more to determine the SR and pin number:

heya…there was something wrong with my pcb…maybe terminition or so…did a new one, assembled it all and now it works as aspected…yoohoo…thank u very much for great support from your side on this…next time i´ll better check triple ;))
