Phatline

so this i solder a new cable, and will report the result. many thx!!! mike

hei, i have 2 of them here, booth not working , they have not been working till the day i first used my code, but since it did not work i uploadet the tutorial_16 svn and edit the code for what I think is to be set for AOUT_NG: // initialize AOUT module AOUT_Init(0); // configure interface // see AOUT module documentation for available interfaces and options aout_config_t config; config = AOUT_ConfigGet(); config.if_type = AOUT_IF_TLV5630; config.if_option = 0; config.num_channels = 8; // INTDAC: only 2 channels supported, 8 channels pre-configured for your own comfort config.chn_inverted = 1; AOUT_ConfigSet(config); AOUT_IF_Init(0); The LED is lighting up, and i followed the connection from the chip 541 till the DAC >>> from the beginning i have done right; to be sure for that, i copyed all info i found about that weired connection: and i think there is something wrong with the documentation, the photo of the ng shows i (i think) a different pinning) also in every shematic or tutorial or wiki you get other names for that pins - its very confusing - can anybody check my multicolor painted connections in graphic above - thanx for that i removed the Discovery board and "biept out" all connections, i finally replaced the 541 on the core.... R33 is also stuffed, and it is a 1K network - all right -but solved nothing. i also tryed a second core, that i have (i have a pair of them), i also measured carefully direct on the DAC GND and +5V all are there. I measured DAC-A output aka "pin 0" and i have 0V to Digital Ground > so nothing. I connected +-12V from a doepfer PSU2 - right from the beginning on... and as far as i can say i have not heated the DAC to much while soldering, i made it quick and clean with a Weller Station where i can change the temperature... i stuck a bit... maybe there is something wrong with the inital code (posted above) thx for any tip

since i make midibox right now.... i have started a wiki, about the configuration (CV-Type Unipolar, Bipolar Power Supply) + Jumper Setting in combination with AOUT_NG ssm2164_getting_started

thx man... great help

hei. sure i can tell, i have made a picture: i have this LFO screen 4times, and i have also 4 screens for Envelope too (=8x scope displays - that are showing 4x8=32ENV/LFOs - i have 4 Channelstrips - this CV-Application will drive Distortion, ACs Filters...) The same is for Envelope, except that when a Note-sustains - it will hold Position and it is not growing, until note is released... its pretty much the same., the LCD-Clear is triggered with a incoming note-on i have in booth cases the knowledge about -how long is the duty cycle, so i dont need to shift or sync display to left or right, the lines is growing and thats it. but also look @ the video i already posted - in the video it does what it should too (ok there are bugs, and the V-Axis has to scaled from 0-63 to 63-0, and the clear-screen is a problem...) the video:

ja i of course a deep look in programmer and loopa and others --- but dont find it soo easy, i am still new to this task, and to crystalize the information in a environment like a programmer - had not worked, it worked not out most of the time in my life... i need the root, but the root itself -for me- is sooo boring that i cant learn it... i am a bit in reverse engenieering... i know what have to done to get what i want, but the syntax is my problem..... i already have the problems with the "many cleared" pixel per frame.... i have to clear every lfo,cycle or env.trigger 1to8 displays, and pixelwise - it is not working -of course i saw already the lcd-clear mios_lcd_clear(), but that clears all displays - also the 8 that need no update the whole runtime (UI-describtion) the is just confusing, and for me not working, it always sayst that it is a function, and for that, the parameters are not right, and it have to initalize, and its not a struct and this and that... is there no "blank" command, that let do this work the ssd1306 by itself?

ok i got rid of the 32pixel offset, by removing that cmd(0x5c) //////// show WAVE-FORM - S C O P E //////// MUTEX_LCD_TAKE; MIOS32_LCD_DeviceSet(14); APP_LCD_GCursorSet(H,V); // (h, v) set insert Position for Bitmap APP_LCD_Data(1 << ( V % 8 )); MUTEX_LCD_GIVE; now i have to find out a smart way to clear a display

what i noticed MUTEX_LCD_TAKE; //////// CLEAR S C O P E //////// MIOS32_LCD_DeviceSet(14); MIOS32_LCD_Clear(); MUTEX_LCD_GIVE;} will clear all connected displays! not only the selected device, thats bad, because 8 displays are showing static values (describtion of UI) a Horiz Vertic - Position will make it not better: MUTEX_LCD_TAKE; //////// CLEAR S C O P E //////// MIOS32_LCD_DeviceSet(14); APP_LCD_GCursorSet(H,V); // (h, v) set insert Position for Bitmap MIOS32_LCD_Clear(); MUTEX_LCD_GIVE;} and this is the worst (not usable slow), but @ least it dont kill the other displays: MUTEX_LCD_TAKE; //////// CLEAR S C O P E //////// MIOS32_LCD_DeviceSet(14); int ho; int ve; for(ho=0; ho<128; ho++) { for (ve=0; ve<64; ve++) { APP_LCD_GCursorSet(ho,ve); // (h, v) set insert Position for pixel APP_LCD_Cmd(0x5c); // send command "Write RAM" to GLCD APP_LCD_Data(0); }} MUTEX_LCD_GIVE; this code for printing out Pixel is working, but it will shift all other and itself vertically about 32pixel! - what i dont understand: //////// show WAVE-FORM - S C O P E //////// MUTEX_LCD_TAKE; MIOS32_LCD_DeviceSet(14); APP_LCD_GCursorSet(H,V); // (h, v) set insert Position for Bitmap APP_LCD_Cmd(0x5c); // send command "Write RAM" to GLCD APP_LCD_Data(1 << ( V % 8 )); MUTEX_LCD_GIVE;

thx for the testpin hint ... lcds still not working ... cant test them, have to made new cable, but dont have any connectors anymore... this will have to wait.... but got 16xOLEDs working on the stm32f4 (also with the knowledge with the testpin)

my tryings with Bitmap, also are not working well this code: Filterbox-V1.zip // calculate H V Positions V = v * aout[x].lfo[y]; if(V <= 0) { V=0;} if(V >= 63) { V=63;} H = h / time * counter[x][y]; if(H <= 0) { H=0;} if(H >= 127) { H=127;} MUTEX_LCD_TAKE; //////// show WAVE-FORM - S C O P E //////// MIOS32_LCD_DeviceSet(14); // clear screen if ( sync_waiting == 1 ) { int h; int v; for (h=0; h<128; h++) { for (v=0; v<64; v++) { APP_LCD_BitmapPixelSet(bitmap, h, v, 0); }}} APP_LCD_BitmapPixelSet(bitmap, H, V, 1); MIOS32_LCD_DeviceSet(14); MIOS32_LCD_CursorSet(0, 0); MIOS32_LCD_BitmapPrint(bitmap); MUTEX_LCD_GIVE; gave me 8 lines on the display and i did not know why! --- really no clue (had the same result yesterday...) un words of the night: STRUCTS and TYPES.... may it be easy when you are the architect of it, but for me it is horror! damm i hate that structs... where are the simple arrays, code, bam ready, next task...... after 6 ours of trying to come to an end with that structs - i make a end and go to bed ... i hate structs! and som other highlights: specially i wanted to get the bitmap thing to run, these documentation, did not help, and got no results after 6 ours: also the structs are other written... for me logical is for example: typedef struct storage { u8 SWING_16th; u8 SWING_32th; u8 SWING_Switch; } store_t; store_t beat; store_t beat_cpy; here i know what is going on... when using them i just write beat.swing_16th... o r copy them with memcpy by typing beat or beat_cpy and so on.... maybe its easyier to just understand following code (i tryed by my own, but it seems that it cant work with arrays...), to make things more directly - in sense of outputing matrices without converting them (my matrice data is most of the time x-y-z generated), maybe anyone can explain this part more exactly ( special that pointer and bitshifts things, and how to more simplyfy the code, for simple arrays as input - and not some crypted file "con"structs) & alternativly how to adapt it for realtime operation (output Pixel @ position [x][y]) i can break it down to: int line; for(line=0; line<8; ++line) { // count from 0-7 & do 8x following code: APP_LCD_GCursorSet(0,0); // set insert Position for Bitmap APP_LCD_Cmd(0x5c); // send command "Write RAM" to GLCD // calculate pointer to bitmap line u8 *memory_ptr = bitmap.memory + line * bitmap.line_offset; // transfer bitmap int x; for(x=0; x<128; ++x) APP_LCD_Data(*memory_ptr++); }

hei i tryed this code MUTEX_LCD_TAKE; MIOS32_LCD_DeviceSet(14); APP_LCD_Cmd(0x75); // Row APP_LCD_Data(V); APP_LCD_Cmd(0x15); // Column APP_LCD_Data(H); static int abyte = 0; abyte = 1 << ( V % 8 ); APP_LCD_Cmd(0x5C); // Write Pixel APP_LCD_Data(abyte); //MIOS32_LCD_CursorSet(0, 0); //MIOS32_LCD_BitmapPrint(bitmap); MUTEX_LCD_GIVE; but its not workin... got this:

now trying to make it with bitmaps... but that is not easyer, not working.... also the "APP_LCD_Clear();" isnt working. when looking @ http://svnmios.midibox.org/filedetails.php?repname=svn.mios32&path=%2Ftrunk%2Fmodules%2Fapp_lcd%2Fssd1322%2Fapp_lcd.c then i ask myself for what there is a "for loop" with "i" when no is used anywhere?

like this: but in Pixel-Resolution

using the ssd1306 i am learning at the moment the handle of graphical displays... specially the waveform display now i stuckking, i already have X-Y coordinates, and a timline... in theory it is working, it works with Characters... but i need pixels i stuck by writing a single pixel to the display, i want to write a pixel every millisecond, and after the time of the loop (loop point 0) it should clear the display... (APP_LCD_Clear();)) is there a way to directly draw a single pixel, without the must of " changing a bitmap, and print the whole bitmap again..." i can set the courser with: APP_LCD_Clear(); APP_LCD_Cmd(0x75); // Row APP_LCD_Data(V); APP_LCD_Cmd(0x15); // Column APP_LCD_Data(H); but then i have no command to activate a pixel, has it something to do with the write ram >>> APP_LCD_Cmd(0x5C);

aout ng: lre8x2 diverse modules

i have made a stop motion video, about the soldering the pcb... i have cut it to 6 minutes, so not all stuffed parts are shown, but most of part-groups the music is drumside made with the BLM: haveing more stop motion videos about lre2x8, core, din, mf-ng, and others... coming in future online (when having time to cut and deciding which music track under it...) (made with a lumix g85)

like it want 2

595 om j10b?

a nother one:

for me it doesnt work out with j10b direct connection to displays http://www.ucapps.de/mbhp/mbhp_lcd_nx2x20_mios32.pdf the documentation uses doutx4 shiftregister at j28 which doesnt exist on core32f4... docu also not saying where to handle pinning software side.

Hi is there a change to get a generic usb-keyboard (abcdefghijklomopqrst...) working in usb-host-mode? i want to display the songtext on the 2x40LCDs, because i cant remember Texts... the most easyiest way would to input the text via Keyboard on the machine, and save it in arrays the other way would be that i have to somehow write it on personal computer, convert it into a readable file and interprete it on mios.... its like karaoke, but sequencer driven... any idea?

some pictures.... and costs if "at it is" costs.ods

i dont have a clue of the sequencer seqV4 features and menue and so on, i used only the hardware for my own program... so i cant say that the seqV4l will do that, you may search for yourself or ask in the forum HERE costs.ods i addet the costs, the parts costs are very exact the price i payed for it. the time is expectet, i dont remember exactly what i need, or can know what i really need exactly. the costs are without keyboard and case material costs (but with exceptet time need and keyboard electronic) also without trackposition display - you have not answered that you need or not... the package to zypern is also expacted for the LCDs there are options... i calculated for standart Backlight LCDs ---green for seq, blue for SID.... for OLED black background ones, it will be far more expensive. some parts i have to source, the seq-v4 panel for example, i dont have this, i must order this from julianf from uk... also the price is on the lower end - i for me take more euro per our in reality - because - my time is more worth then any money ;) of world... i have a plan, and i want to change things in my environment - its horrible here in austria (planes that makeing dust doing changing climate here, toxic substances in water, dessert like fields of wasted earth, EU-orders, stupid people, meat-eaters, nonsense roman empire rules...)

@ sequencer: i also have a seqv4 wilba cs here, without case i dont use anymore (i prototype much, housing in my case make no sense- i prefer woodplates and naket pcb), also i have much other modules here, to complete any whises (except vca vcf they i need on my own...) @moog case, could fit, but dont know the dimensions on this device, dont think that a wilba seqv4 cs have enough place with the wilba SID cs in row... maybe you take a look @ @ my wilba sid is up and running, but not ready built in the case @ the wilba aluinimium frontpanel + paytec case, i could try sale, in some future maybe one need them, the ui-pcb + lcd would be bit harder... but ok i could live with that @ keyboard sold as parts - ok, we talk when your reserche is done - till then, mike.
