the DIN6DOUT4 has pulldown/up resistors on board?

i am offically a artist. i pay social insurance for that. my time is free for midibox making music for contest cd website or gig. have a girlfriend spending lot of time in love. cooking and houshold on my own... and midibox coding planing building consume the rest of it. since i need the devices for a gig end of february i dont have time for tutorials... but when i have some spare time i would make some video doku-to see what to have done BUT not a detailt tutorial for that it is to much information. but i think in german and for a mios based uset project so it would help only a small group anyway. so i have to rethink it i also dont have the best cam equipment nor mony for that..
maybe this and others is a reason that there are no video tuts outthere ,;)

moturola g4 play. android. firefox
when making a new pm: onboard display pops up and the sendbutton is hide.
there need to be more place under the send button. or. the possibility to "overscroll"

if you have that many. i would take 20 + 1xpcb
i was asking because on ebay you have to choose between spi ans iic. when choosbing spi theboicture shows a 4 pinner; gnd vcc scl sca
do i need spi?

THX! without that i would have been lost!
worked at the first moment!
i had enough to close and re-open the Mios-Studio every time when uploading new code... specially while programming over weeks daily
deep into code...(and that rescan joke? not funny)
my cores bootloader is setup ed, to show up as "MIOS32" (when not in bootload mode), so i hardcodet that in mios-studio to be set when press "Rescan mididevices", working under linux mint kernel 4.4.0-98
no more closing MidiStudio, or have to close multiple-open-instances because of codeing and trying and uploading, then everytime the resize of the window, search and open hexfile and so on. Of course that is hardcodet, but in my case it is good this way, now i know how to compile anyway - thx
open: svn/mios32/trunk/tools/mios_studio/src/gui/MiosStudio.cpp
edit: i deleted all from"case rescanDevices" to "break;" and wrote this instead: (the line is about 955 or so)
case rescanDevices: closeMidiPorts(); initialMidiScanCounter = 1; getMidiInput(); getMidiOutput(); setMidiInput("MIOS32"); setMidiOutput("MIOS32"); break;
dont really know exact what is going on there, but for me its working, and thats enough.
also some colorchanging by searching the gui/....cpp filesvia
g.fillAll(Colours::black);but the background of the main-fields are still white... to bad...

Hi,
i want to modify the blm_scalar app a bit
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 -

hm what size has this wchar_t?

if(edit & 0x0f)memcpy(&loop_copy, &loop[track], sizeof loop_copy);clever i like that
but i planned it more like: check which things have to copyied, so i can copy PB+NOTES, but not CC+Loop-Information, (for default)if i get it right: in your thought i can always copy only one thing: PB, All, Notes or Loop-Info
but i can still use memcpy with for example:
if( (edit[0]==1) && (edit[1]==1) && (edit[1]==1) && (edit[1]==1) ) memcpy(&loop_copy, &loop[track], sizeof loop_copy);THX for your help guys!
for the rest i will take me time on 23.12... today we make fire in the snow, and celebrate the 21.12 to restart the sun-circle
happy new sun year, skol!

ok understand, i let the the file describtion in....
oje...
there is something wrong with the code,
http://wiki.midibox.org/lib/exe/fetch.php?media=phatline:seq-melody-footboard-beta.zip
when i make arrays with 8x512, or arrays with 8x1024, the Files on SD-Card is always 5,6kb size, also on 1024 i got hardfaults when copy those structs into arrays (copy paste clear clips), by 512 no hardfault
typedef struct storage { u16 PB [512]; u8 SEQ[512] [8]; u8 MSQ[512]; char leader; char virgin; u8 length; u8 decay; u8 rythm; u16 bpm; } store_t; no difference in SD-File-Size! typedef struct storage { u16 PB [1024]; u8 SEQ[1024] [8]; u8 MSQ[1024]; char leader; char virgin; u8 length; u8 decay; u8 rythm; u16 bpm; } store_t;also i initialize all Arrays, but actual most of them (all except the first member loop[0] in the program are 0-out
void APP_Init(void){ //initalize 8 Clips with standart values u8 a = 0; for ( a=0; a>8; a++ ) { loop[a].leader = 0; loop[a].virgin = 1; loop[a].length = 1; loop[a].decay = 60; loop[a].rythm = 4; loop[a].bpm = 120; //initiate Pitchbend u16 b; for(b=0; b<512; b++) { loop[a].PB[b] = 8192; } }; //Initiate Pitchbend - copy paste buffer u16 b; for(b=0; b<512; b++) { PB_copy[b] = 8192; } }the 1024 thing i think is clear, it takes to long to calculate all the data, i would need something like a xtask... but i dont figured out how to make out of a
Quotestatic void Edit_Clip(u8 track, u16 clip, u16 job); a static void Edit_Clip (void *pvParameters);
i know:
QuotexTaskCreate(Edit_Clip, (signed portCHAR *)"Edit_Clip", 256, NULL, PRIORITY_Counter, NULL);
i use such things for counters in ms tact (decay-counters, blink blink...), but not for a function that gets called, work something out, and done...
for example:
static void Decay(void *pvParameters){ //Send Note OFFs after a while portTickType xLastExecutionTime; xLastExecutionTime = xTaskGetTickCount(); // Initialise the xLastExecutionTime variable on task entry while( 1 ) { vTaskDelayUntil(&xLastExecutionTime, 1 / portTICK_RATE_MS); for(DcyNteCount = 1; DcyNteCount < 128; DcyNteCount++) { for(DcyTrkCount = 0; DcyTrkCount < 8; DcyTrkCount++) { if (MeloDecayTIMER[DcyTrkCount][DcyNteCount] != 0) { MeloDecayTIMER[DcyTrkCount][DcyNteCount] --; if (MeloDecayTIMER[DcyTrkCount][DcyNteCount] == 0) { MIOS32_MIDI_SendNoteOff(MelPortOut, MeloOutCh[DcyTrkCount], DcyNteCount, 0); MIOS32_MIDI_SendNoteOn (MelPortOut, MeloOutCh[DcyTrkCount], DcyNteCount, 0);}} }} }//End While }//End TICK 0 >>> 1ms Task... -

FILE_ReadBuffer((u8*)loop, 8 * sizeof(store_t));
FILE_WriteBuffer((u8*)loop, 8 * sizeof(store_t));
the trick is to use "sizeof", that calculates the data size of the structure "store_t" in bytes. Multiplying it by 8 if you want to read/write 8 of these structures at once. Make sure, that the variable "loop" is big enough to hold the data.
would assume that all my tracks saved in a single file, and thats not the case, since i need to load the clips independendly for launching via BLM, but also need to load the clips via Program-change also
so it ends up with:
case 2: //LOAD all Clips - FOR P R O G R A M C H A N G E for( t=0; t<8; t++) { MUTEX_SDCARD_TAKE; sprintf ( filepathL, "sq/%d-%d.sq", t, clip ); FILE_ReadOpen ( &midifile_fi, filepathL ); FILE_ReadBuffer ( (u8 *)file_type, 4 ); FILE_ReadBuffer ( (u8 *)loop[t], sizeof(store_t) ); FILE_ReadClose ( &midifile_fi ); MUTEX_SDCARD_GIVE; //Calculate new Loop Lengths Loop[t] = loop[t].length * MainLoop; }
2 hours ago, Antichambre said:FILE_WriteBuffer((u8 *)loop[track], sizeof(store_t));
for a single track...
best!
by the way, do i need that
FILE_WriteBuffer( (u8 *)file_type, 4 ); //"SQ01" = 4 Positons
for what platforms do i need a filetype?
compiler says for the line: FILE_WriteBuffer((u8 *)loop[track], sizeof(store_t)); :

i am stucking @ the moment, while i know how to use it instead of my normal arrays, i dont know how to write the whole struct into file...
ok here my struct: store_t loop[8] ,
how can i read/write them now into my FILE?
a struct is not named in MIOS32 functions doku

* Using structs to read in data, e.g. from SD card will speed up things massively, as every further read may block i/o.
* Memory alignment should only be a problem, if you access data all the time, tens of thousands of times per second :), if you only frequently need some data, don't worry too much, these modern microcontrollers are orders of magnitude faster than old machines. Use the correct memory size for your data and you will be good.
* What you need to worry about is the data size of your program, so use the smallest possible data type in arrays.
In short, our core is very fast, but has only very limited ram. It can calculate like a boss, but can only store 3x more than your old C64 :)
thx good to know!
i will try them structs
code is for MelodienSpeicher, where arrays[8][512] polophonic played in 16th (Pitchbend, NoteOn/Off), and also hope that dont hurts when using structs
u16 PB[8][512] = {{}}; // 8192: inital No Pitchbend! u8 Sequence[8][512][8]={{{}}}; //8Tracks, 512Steps, 8NotePolyphony u8 CC_MSQ[8][512] = {};//Motion-Sequence of one CC (Control-Wheel of Keyboard s16 TrackClipboard[512][8] = {{}}; //Copy actual Track into ClipboardBuffer u8 StepClipBoard[8][8] = {}; //Just a memory container to copy paste Sequencer Steps

to be prepared, today read a lot about structs, and memory-save/performance/code-readable much to optimize .... it seems that there are things to keep on eye, to avoid heavy bus-load
...like order variable by byte size, and others which i cant summize a "i understand"...
importend for me is that the the program goes fast thru, i dont have memory problems, i think, since it is a sequencer timing is No1
by using struct it will slow down program-process? a normal variable-array is slower? > time not so importend - in case of loading from SD-Card to RAM, but for RAM-Access-time in the Program, hope that question make sense?
then there where people who said, that when i dont use 32bit types, the program have to calc my 1bit 8bit or 16bit into 32bit -memory-slots- and access time will go not so good, other saying that this is only for x86, arm a nother story... dont know: should i use "int" as standard (except for the big sequencer Arrys > memory to low i expirienced today more a 8 or 16bit...) or should i use u8 or u16 instead? i mean when i dont use structs for all those "not clip related"-variables, just single u8 variables make it any differnce at all?

Try:
// write FILE_WriteBuffer((u8 *)PB[track], sizeof(PB[track]); // read FILE_ReadBuffer((u8 *)PB[track], sizeof(PB[track]);I did it and your project was compiled without error...
should it does it the same? incl(track) (step) cant wait to try it at home.many thx.4that. mike.
14 hours ago, Antichambre said://write u8 PB8[STEP_NUM*2]; for (i=0; i<STEP_NUM; i++){ PB8[i*2] = (u8)(PB[track][i] & 0xff); PB8[i*2+1] = (u8)(PB[track][i] >> 8); } FILE_WriteBuffer((u8 *)PB8 , sizeof(PB8)); //read u8 PB8[STEP_NUM*2]; FILE_ReadBuffer((u8 *)PB8 , sizeof(PB8)); for (i=0; i<STEP_NUM; i++){ PB[track][i] = (u16)((PB8[i*2+1] << 8) + PB8[i*2]); }
