Phatline Posted January 5, 2018 Report Posted January 5, 2018 (edited) Hi, i want to modify the blm_scalar app a bit http://svnmios.midiboxorg/filedetails.php?repname=svn.mios32&path=%2Ftrunk%2Fapps%2Fcontrollers%2Fblm_scalar%2FREADME.txt i want to use it in standalone and via midi/sysex... so my question: how to call the BLM internally? when i want to display a "array[16][16]=0 or 1 or 2;" i know i can call it like below but is there a more direct way to use it? thx. mike void APP_Background(void){ u8 chn = 0; u8 note = 0; u8 velocity = 0; for(chn=0; chn<16; chn++){ for(note=0; note<16; note++){ velocity = Seq[chn][note]; if( note <= 0x0f ) { //note<=15? // BLM16x16 LEDs led_mod_ix = chn >> 2; led_row_ix = ((chn&3) << 1) + ((note >> 3) & 1); led_column_ix = note & 0x7; //7 modify_led = 1; } else if( note == 0x40 ) { //note==64 // extra column LEDs led_mod_ix = 4; led_row_ix = (chn&3) << 1; led_column_ix = chn >> 2; modify_led = 1; } else if( chn == 0 && note >= 0x60 && note <= 0x6f ) { //Chn0, note>=96, note>0111 // extra row LEDs led_mod_ix = 4; led_row_ix = 1 + ((note >> 1) & 6); led_column_ix = note & 3; modify_led = 1; } else if( chn == 0xf && note >= 0x60 && note <= 0x6f ) { //Chn15, note>=96, note>0111 // additional extra LEDs led_mod_ix = 4; led_row_ix = 1 + ((note >> 1) & 6); led_column_ix = 4 + (note & 3); modify_led = 1; } if( modify_led ) { u8 led_mask = 1 << led_column_ix; // 90 xx 00 is the same like a note off event! // (-> http://www.borg.com/~jglatt/tech/midispec.htm) if( velocity == 0x00 ) { // Note Off or velocity == 0x00: clear both LEDs blm_scalar_led[led_mod_ix][led_row_ix][0] &= ~led_mask; #if BLM_SCALAR_NUM_COLOURS >= 2 blm_scalar_led[led_mod_ix][led_row_ix][1] &= ~led_mask; #endif } else if( velocity < 0x40 ) { // Velocity < 0x40: set green LED, clear red LED blm_scalar_led[led_mod_ix][led_row_ix][0] |= led_mask; #if BLM_SCALAR_NUM_COLOURS >= 2 blm_scalar_led[led_mod_ix][led_row_ix][1] &= ~led_mask; #endif } else if( velocity < 0x60 ) { // Velocity < 0x60: clear green LED, set red LED blm_scalar_led[led_mod_ix][led_row_ix][0] &= ~led_mask; #if BLM_SCALAR_NUM_COLOURS >= 2 blm_scalar_led[led_mod_ix][led_row_ix][1] |= led_mask; #endif } else { // Velocity >= 0x60: set both LEDs blm_scalar_led[led_mod_ix][led_row_ix][0] |= led_mask; #if BLM_SCALAR_NUM_COLOURS >= 2 blm_scalar_led[led_mod_ix][led_row_ix][1] |= led_mask; #endif } } } }} // END - FOR - LOOPS Edited January 5, 2018 by Phatline Quote
TK. Posted January 6, 2018 Report Posted January 6, 2018 You can find the API to access the LEDs directly under: http://midibox.org/mios32/manual/group___b_l_m___s_c_a_l_a_r.html Best Regards, Thorsten. Quote
