Phatline

thanks for the thip... he says he has a Ipad... but maybe there it is the same problem, but with a extrem more complicated way to do that solution...

see title.... a friend of mine has a iOS device (apple), there it shows only 1 USB-Midiport, while on his Win-PC with the same STM32F4-Board it shows 4 Ports! any idea to fix this on iOS?

still in the build... i addet a wiki, with the progress: Triggermatrix 4

i had bad expirience with cheap Solder-Lead - which FLUX has low resistance > better clean all up!

i changed the post - with the requested/answered questions: 90+40USD(Fedex)=130USD = 110€ the import taxes gets % on the 90USD (76€) + a handling fee (cant remember exactly its about 25-40€ only for the toll-affort..) i suggest about 60€ for the import... so its arround max 170€ Maxim decidet to go for Frontpanels.de

China: 90 USD Additonal Infos: Production time will be about 15 days for sample and 25 days for mass production. Yes the finish is black anodizing as your requirement. Shipping cost for 1 pcs will be 40 USD by FedEx. As for the import taxes of your country, i m not sure if there will be a cost or not. But we usually write the value very low to avoid the import taxes. estimate: 90+40USD(Fedex)=130USD = 110€ the import taxes gets % on the 90USD (76€) + a handling fee (cant remember exactly its about 25-40€ only for the toll-affort..) i suggest about 60€ for the import - summed... so its arround max 170€

frontpanels.de 260€ incl VAT incl Shipping https://shop.frontpanels.de/Frontpanels (additional print: 22€)

the prototype is built, and used by me to make electronic live music... now time for Serial Number 1, here some progress update - soon there will be a 2nd User in the world who uses a Triggermatrix ;) since the Old BLM of @latigid on is not produced anyone - this will be a Unikat..... A Render of the Anodized-Alu Color theme: or black... Made a PCB for the extra Buttons: the rest are MBHP Modules: 2x MidiIO, CoreSTM32F4, and DINX4 + BLM16x16+x from Latigid on... some wood, a CNC made Frontpanel, and Buttom+Back-DIY drilled plates. to the orginal Triggermatrix - i addet a Flame Function, and 9 OLED-Displays, LoopA Support, and and a good Song-Function, Ableton-like-clip-launcher

I have to order a big panel`(ca. 40x36cm...) ... for this i will get me some Quotes from different Services... And then make a price-comparison here... Do you Have some recomendations? Panel - for the quote: TM-V4-Dimensions.pdf

LoopA, Triggermatrix V4, Nordrum2, Nordrack3, TR606, Korg ER1, FB383, Neptune2, Analog-Heat, TCM350 and a lot of small midibox DIY stuff.. recordet on Zoom L12 - no master - but cut Triggermatrix: while the song-structure is playing i Interrupt it "rotz-frech" with a view buttons, changing Master Velocity, and Master Decay...giving rolls breaks... having fun

hab so gelöst: in der app.c vom loopa: ///////////////////////////////////////////////////////////////////////////// // This hook is called when a MIDI package has been received ///////////////////////////////////////////////////////////////////////////// void APP_MIDI_NotifyPackage(mios32_midi_port_t port, mios32_midi_package_t midi_package) { //909 Phatline /// MIDI Control & Program-BANK LOAD STORE #define CC_PC_Bank 32 // Bank for Program-Changes in order to use more then 128 songs.... static u8 Bank = 0; // Bank 0 = PC 0-127, Bank 1 = PC 128-255 .... #define CC_SCENE 33 // SCENE 0-5 #define CC_Save 24 // external store signal, so this app save @ same time like external (only one save button in setup) switch( midi_package.cc_number ) { // each Bank has 128 Programchanges... case CC_PC_Bank: Bank = midi_package.value * 128; break; // Program-NR + Programbank case CC_Save: saveSession(midi_package.value + Bank); break; case CC_SCENE: if(midi_package.value < 6) { sceneChangeRequested_ = midi_package.value;} break; break; } } //909 Phatline /// P R O G R A M C H A N G E Program if( midi_package.type == ProgramChange) { loadSession(midi_package.evnt1 + Bank);} i remote all my self developed gear with Bank CC32.... and to SAVE i use for ALL: CC24 .... so i only have to press SAVE on the MAIN-Gear and all slaves do the save. For Scene Select i took CC33. This SceneChangeRequest is in SYNC! - and i did not change any part of the LooPa -it is already there... except of the part i postet here.

LoopA2 feeds Triggermatrix4 with Melodys - Nordrack 3 = Synths - NordRum = Main-Beats, Korg Er1 and 606 thru filter distortion and triggered - envelopes

that topic comes again into my mind nowdays... maybe it is the winterproject 2021

i got it: // change Folder Directory - letter loadet from previos loaded SYS-File char Folder = 'a'; char path[8]; strncpy(path, "a ", 8); path[0] = Folder; statusDir = FILE_DirExists(path); // ask file.c: exist a folder "a/" on the CARD? // or: char Folder = ’A’; char path[8]; // Build File Path/0.t4 " sprintf (path, "%c/0.b4",Folder); // ask file.c: exist a file "A/0.b4" on the CARD? // statusFile_patch = FILE_FileExists(path); and for delete all Files - and Directory(if all files are known and already deleted // you need to delete each file on its own... int c; for (c=0; c<256; c++) { char remove[9]; // make a new filename depending on the counter value sprintf (remove, "%c/%d.b4",Folder,c); // Remove FILEs MUTEX_SDCARD_TAKE; FILE_Remove(remove); MUTEX_SDCARD_GIVE; } // Remove Directory (can only be done if it empty // build path char remove[8]; sprintf (remove, "%c",Folder); MUTEX_SDCARD_TAKE; FILE_Remove(remove); MUTEX_SDCARD_GIVE; whoud be interesting, how to delete a folder if the Files inside are not known?

thats works: FILE_DirExists("a"); // check for a Folder named a get the warning: "warning: passing argument 1 of 'FILE_DirExists' makes pointer from integer without a cast [enabled by default]" char directory = ’a’ FILE_DirExists(directory); // directory is a variable is it possible to check for a Variable-Dir? file.c says: ///////////////////////////////////////////////////////////////////////////// //! Returns 1 if directory exists, 0 if it doesn't exist, < 0 on errors ///////////////////////////////////////////////////////////////////////////// s32 FILE_DirExists(char *path) { DIR dir; if( !volume_available ) { #if DEBUG_VERBOSE_LEVEL >= 2 DEBUG_MSG("[FILE_DirExists] ERROR: volume doesn't exist!\n"); #endif return FILE_ERR_NO_VOLUME; } if( !path || !path[0] ) return 0; // empty directory name - handle like if it doesn't exist return (file_dfs_errno=f_opendir(&dir, path)) == FR_OK; }

i uploadet "$MIOS32_PATH/apps/misc/usb_mass_storage_device" on a core stm32f4... the lcd says "sd connected"... but it is not shown as device in browser nor diskmanager (where you see all mounted or not mounted partitions...) is there a driver needet? (maybe only mac tested?)

or other midi devices... or you could program your own custom sequencer into the matrix (it is a32bit core now?...thats whaz i did with V1 off the blm16*16+x

try a temporar reset line for that display... (could be done by making a adapter cable between OLED and PCB ...while you cut the Reset Wire, and feed there the 1K 10uF thing in....) - and see what happens else i would try to set X8 to X9 (only for testing - not that is right - X8 is right...) then i would try to set the LCD Type to SSD_1306 Rotated (not that is right...) then i would post the board-file-picture (i cant see anything on your Separated Top/Buttom Pictures...i become eye and brain-cancer)

dont think that is the right trace...but PD7 by looking on the Shematic is only for the Display... but i dont know why? may it is needet for a special LCD? or some feedback/control/detection routine? (GPIO as input?) i would try to upload the bootloader app, and look if you can see anything on LCD8 --- i too have a discovery board with latest bootloader and 9 LCDs and on my machine everything is alright > so we can cancel out a mios/bootloader-PD7 problem but PD7 could be buggyerwise set as gpio out in your App you have on your machine (NG?)

you removed all Solder-Flux? (Aceton...) (i always have problems with that low-impedance Shit (<1K! between to pins because of some flux...) by swapping cores you mean the whole Motherboard and Discovery? if only discovery > try to replace that 595er... send a picture of that "garbled" --- if it looks like noise then you may not set the Displays right (bootloader-app > help > displays num x and y.... maybe one to less?) else post a board picture (with top and buttom layer in one....) may there is something you dont see....
