I want to program my own software running on the “Generic” SEQ-CS-Wilba - UI- PCB (Software: Triggermatrix)
it has nothing to do with the SEQV4, except the BPM part, so ripp off the UI-Code for the Button-Matrix from SEQV4 is a no go > i dont understand it.
i first wrote a small app to show me DIN-PINing off all Btns, (following Pins have a offset off 4 Shiftregisters … because a MB-LRE-8x2CS is in the chain)
then realized that not every btn has its very own PIN…ok i thougt, i know such things from LEDMatrices the other way arround.
But Scan Matrices (BTNs) is newland for me… i quick search give me: mios32/trunk/apps/examples/fastscan_button_matrix_16x16 <<< should i start with that, or is there a more simple/better for learn-Code somewhere
thanx

As far as I know, there’s no circuit diagram for the SEQ PCB, but you could trace the layout pretty easily. Are you familiar with the concept though? A button matrix scans inputs via DIN and sends pulses on the DOUT chain to close the circuit. It’s not high-level programming, but you could load up MB_NG and define a button matrix to test the concept. just made a CS for his SEGA Genesis build, perhaps he has some advice.
the concept sounding logical… i think i have something seen here http://svnmios.midibox.org/filedetails.php?repname=svn.mios32&path=%2Ftrunk%2Fapps%2Ftutorials%2F029_keyboard_velocity%2FREADME.txt
no, mb_ng is to big (cant understand code which i havent programmed myself, or stripped down to the minimum working task)
have to try to strip down the tutorial 29 code, by remove the Velocity calculating.

The BLM_X is the right choice (and not the KEYBOARD driver)
Programming Example: http://svnmios.midibox.org/listing.php?repname=svn.mios32&path=%2Ftrunk%2Fapps%2Fexamples%2Fblm_x%2F
Following configuration is required in mios32_config.h:
// configure BLM\_X driver #define BLM\_X\_NUM\_ROWS 8 #define BLM\_X\_BTN\_NUM\_COLS 8 #define BLM\_X\_LED\_NUM\_COLS 8 #define BLM\_X\_LED\_NUM\_COLORS 1 #define BLM\_X\_ROWSEL\_DOUT\_SR 1 #define BLM\_X\_LED\_FIRST\_DOUT\_SR 2 #define BLM\_X\_BTN\_FIRST\_DIN\_SR 2 #define BLM\_X\_ROWSEL\_INV\_MASK 0x00 #define BLM\_X\_DEBOUNCE\_MODE 1
Schematic which shows the DIN/DOUT mapping: http://www.ucapps.de/midibox_seq/mbseq_v4_dio_wilba_layout.pdf

BLM_X works well and was relatively easy to use. I even fixed a couple bugs in it along the way.
yesss… Triggermatrix is on the way to generic
SOFTWARE: i stripped it a bit, and something… to find the pinning… and with pinning its easyer to program…
