ok solved it with:
// BPM u16 value= BPM*10; buf[7] = value % 10; value = value / 10; buf[0] = value % 10; value = value / 10; buf[1] = value % 10; value = value / 10; buf[2] = value % 10; -
Hi,
i am currently finishing the TPD-Displays PCBs, and i write a Test App/or my first skeleton-UI to use it.
Its all clear so far, i can print single digits, i know the pattern, the pinout.....
i want to print for example:
float BPM = 128.5; // for Example for Digit 1 2 8 5 --- As BPM Display
but i stuck by Divididing the BPM Value into single Integers, by searching in internet i found:
int i = BPM*10; // Elemenate FLOAT Digit! static char buf[4]; sprintf(buf, "%05.2f", i); // split it into CHARsbut that dont work at all... (print "0" on the first digits, the others are OFF)
i later print the "buf[x]" value to my Digit --- that works fine, when initalize "TPD_SEG" by hand with iniatl values, but not when filled with above code!
// Transcode To Shiftregister-Friendly Array static u8 x=0; for (x=0; x<4; x++) { // 7 Segment PINOUT // [6] // [1] [5] // [0] // [2] [4] // [3] [7] // switch (buf[x]) { case 0: TPD_SEG[x][0] = 0; TPD_SEG[x][1] = 1; TPD_SEG[x][2] = 1; TPD_SEG[x][3] = 1; TPD_SEG[x][4] = 1; TPD_SEG[x][5] = 1; TPD_SEG[x][6] = 1; TPD_SEG[x][7] = 0; break; case 1: TPD_SEG[x][0] = 0; TPD_SEG[x][1] = 0; TPD_SEG[x][2] = 0; TPD_SEG[x][3] = 0; TPD_SEG[x][4] = 1; TPD_SEG[x][5] = 1; TPD_SEG[x][6] = 0; TPD_SEG[x][7] = 0; break; case 2: TPD_SEG[x][0] = 1; TPD_SEG[x][1] = 0; TPD_SEG[x][2] = 1; TPD_SEG[x][3] = 1; TPD_SEG[x][4] = 0; TPD_SEG[x][5] = 1; TPD_SEG[x][6] = 1; TPD_SEG[x][7] = 0; break; case 3: TPD_SEG[x][0] = 1; TPD_SEG[x][1] = 0; TPD_SEG[x][2] = 0; TPD_SEG[x][3] = 1; TPD_SEG[x][4] = 1; TPD_SEG[x][5] = 1; TPD_SEG[x][6] = 1; TPD_SEG[x][7] = 0; break; case 4: TPD_SEG[x][0] = 0; TPD_SEG[x][1] = 1; TPD_SEG[x][2] = 0; TPD_SEG[x][3] = 0; TPD_SEG[x][4] = 1; TPD_SEG[x][5] = 1; TPD_SEG[x][6] = 0; TPD_SEG[x][7] = 0; break; case 5: TPD_SEG[x][0] = 1; TPD_SEG[x][1] = 1; TPD_SEG[x][2] = 0; TPD_SEG[x][3] = 1; TPD_SEG[x][4] = 1; TPD_SEG[x][5] = 0; TPD_SEG[x][6] = 1; TPD_SEG[x][7] = 0; break; case 6: TPD_SEG[x][0] = 1; TPD_SEG[x][1] = 1; TPD_SEG[x][2] = 1; TPD_SEG[x][3] = 1; TPD_SEG[x][4] = 1; TPD_SEG[x][5] = 0; TPD_SEG[x][6] = 1; TPD_SEG[x][7] = 0; break; case 7: TPD_SEG[x][0] = 0; TPD_SEG[x][1] = 0; TPD_SEG[x][2] = 0; TPD_SEG[x][3] = 0; TPD_SEG[x][4] = 1; TPD_SEG[x][5] = 1; TPD_SEG[x][6] = 1; TPD_SEG[x][7] = 0; break; case 8: TPD_SEG[x][0] = 1; TPD_SEG[x][1] = 1; TPD_SEG[x][2] = 1; TPD_SEG[x][3] = 1; TPD_SEG[x][4] = 1; TPD_SEG[x][5] = 1; TPD_SEG[x][6] = 1; TPD_SEG[x][7] = 0; break; case 9: TPD_SEG[x][0] = 1; TPD_SEG[x][1] = 1; TPD_SEG[x][2] = 0; TPD_SEG[x][3] = 1; TPD_SEG[x][4] = 1; TPD_SEG[x][5] = 1; TPD_SEG[x][6] = 1; TPD_SEG[x][7] = 0; break; } } -

I have 3 TIA Cartridge PCBs, pay me the postage (AUSTRIA) - and i give it away for free:
for info see here: http://wiki.midibox.org/doku.php?id=midibox_tia#the_midibox_tia_cartridge_version
What not includet is: the 24LC512 aka "Bankstick", the 7805 aka "Voltage Regulator", the TIA aka "Soundchip", the 6N138 aka "Optocoppler".
the 24LC512 to solder is not for Beginners!
the Microcontroller is Preprogrammed with MIOS.

Thanks phatline.
here is the Link: https://github.com/midibox/mios32/tree/master/apps/sequencers/MB909hope that Works

Hi.
Has anyone a working mb909 firmware (the one from jef) for the lpc17 Core. I found the directory on Github but i am Not able to compile. ( If its compilable anyway!).
There must be a hex file on someone’s harddrive out there.
thanks Chris’ssend me the source-files (or give me a link), and i compile it... (but dont ask me about the firmware, didnot used it, nor i was involved in it...)

Question:
at the end, what is the performance of this RGB-Ledrings - in sence of RAM, CPU, and so on...
I imagine a simple midi-controller app, will do fine, BUT:
i am asking, since most my applications are on the limits on the Microcontroller (mostly ram, sometimes CPU, > sequencers, synths), is this done by CCRAM now, is it the same perfomance like using H595 Registers and some single Color LEDs, some kind of background task? or is this heavy load, and i should forget the last 3 Pages i read...? If i have already a APP that uses 90% or more RAM (for example) will force that to NOT boot anymore? (i have read the last 3 pages)
thx for sharing your experiance

Except that I pretty sure you can remove some of the schmitt inverter buffers, you can do this. ;)
If the target MIDI devices have different MIDI channels they will receive separated Voices messages.
If the target MIDI devices are some midibox cores then just change their ID, as they can receive different SYSEX too.Ah... i thought they have to be inverted back, thinking of the signal is 180° "inverted" and has to be "inverted again"...
(yes Midibox cores...) Good to know that the ID will manage the Sysex "Channel"!

i need to handle up to 16 (MIOS32) Devices, The OUT >>> Thrubox is the simple thing (i think), is that Shematic correct? (ignore the boxes on the rightside, these are Shroudet Pinheaders to cable my devices with Ribboncables...since that is cheaper then the DIN-Thing)
I know there will be a M16-Module, but i think for my task it is a bit overkill (maybe on price...)
but what is when i have 16 MIDI-IN to handle, merge isnt possible or?, or is it possible to adress 16 MidiinPorts on a STM32F4?
else it will be M16 in the end....
background: I need to copy/route Patches (arreys of Data) from one Device to the other. (a recordet Envelope, Size off [4][4096]), dont really know at the moment how to achive that (Sysex?)
there is one Remote Device, and 16 Slaves.... - so the data should be sent from one Slave to the Remote Device, and from the Remote Device there it will be sent to one of the other Slaves.... (they share the same PSU)
...CV1...

i renamed the title...treat thread
thanks!
English: mounting-block/cube , cube standoff
German: Gewindeblock or Montageblock or better Leiterplatten-Montageblock (because Montageblock is used for Water-Installation-"Montageblocks" too)
buerklin (29,75 € incl VAT, excl Shipping)
ettinger (52,44 € incl VAT, excl Shipping)
a bit strange that Reichelt/Mouser doesnt have it, they all have such Nylon Variants: https://www.reichelt.com/de/en/mounting-block-m3-16-mm-natural-rnd-610-00209-p254065.html?r=1
-
Does someone know what name this M3 standoff has? It is used for example to mount PCBs to a Frontpanel!
Name in German/English, and maybe where to get them.
thx!

@Phatline close the VBAT jumper, on the bottom side if you use the pin 32 as 3v3 output.
Yes need it for a MCP6002 Rail.... is the jumper on the BOTTOM of the Dipcore?

i made PCB for Pick and Place Service... and updatet the Wiki: (now waiting for the boards to come)

ok then i take J16 RC2 (PA4) and J16 RC1 (PC4)
which are used for SD-Card - which i dont need here. so i gues MIOS32_DONT_USE_SDCARD ?
@ Type DEF - is this done like on J10 for example:
MIOS32_BOARD_J10_PinInit(0, MIOS32_BOARD_PIN_MODE_OUTPUT_PP);
MIOS32_BOARD_J10_PinSet (0, 1);
for me Clear how to make it with J5 and J10
>>>
MIOS32_BOARD_J16_PinInit(0, MIOS32_BOARD_PIN_MODE_OUTPUT_PP); ???
thx

i made a nother design with your Dipcore as brain (clock2audio2clock)
I need one more LED in this shematic:
every pin which is no connected (yellow cross) - i dont need - so these are possible for LED.
any possible? thx 4 help - mike

currently working on a eurorack version - with DIPCORE as a brain... will be modular in a midibox of way ;)
plan is to use for every filter, or amp or efx or mixer.... to use one off this "motherboards", to do basic stuff like "lfo, env1 env2, motionsequencer, cv mixing" - and then for every filter or whatever to make a decided "beside panel" ( cv-matrix, or simple encoders with displays to show and save the values --- memory modular...)
-
as far i understand you take CORE32 connect that 16x16 FPGA Thingi - and you have very fast 16x16 Midi I/Os with large FIFO-Buffers - that are accessable from MIOS32-Code - your APP could be a router or a sequencer that dumps out AAALOOOT of notes - or whatever you make out off the MIOS32 (C). but maybe @Antichambre want to enlighten you ;)
-
may look @ http://wiki.midibox.org/doku.php?id=m16
will come in future, not released yet - ask antichembre - for infos

ok here is the kicad library for the V2C
(as 3D Modell i took a IC-Socket + a Dip40 IC on it...)

ich hab noch 2 stück ssm2044 filterchips, hier würd die Platine gerne nehmen.
ja eine lade mit der Aufschrift "Platinen wartend" "Platinen Teil fehlt" hab ich auch... und da liegen auch noch Platinen von 2008 drinnen... dieses Jahr hab ich aber viel aufgeholt.
-
if i want to use the onboard USB not to be onboard? In sense of routing to a Connector on frontpanel... in order to load new code into it.... i mean the one for flashing new Mios Applications...
is this possible, which are pins to go? (a few of them are host-mode i guess)

yes, i tried several times to understand the seqv4_ in the end i did not understand, and endet by diy from ground. my c- vocabular is based on "need to know" to get it fixed, and while duing stuff it grows.
