thank you Gerald, i think i'll wait until the card reader is here. I'm away the next few days so it's worth waiting. i dort see any button presses with the default NG configuration. but i can send messages from MIOS to DOUT. i will recheck the DIO boards again, but im shure they are ok, because all 3 of them do the same error... cheers

sorry man, thank you million for your help but you are going into the wrong direction. lets forget the rgb button! i managed to get the leds work, i'm aware about the common anode... lets keep it simple. if I'm doing a short between Vs and D0-D7 of J3 on the DIN then i should get a message in the MIOS right? it's not happening...

the switch pins are connected as you wrote: C1=0V NO1 to DIN the scematic above is indeed an other button, a single color. i test the button behaviour with this one for the moment. The other RGB LED/switch looks like this this: But anyway it's not working either with the RGB button switch... i think the problem has to be somewhere else...

is there a way to test the Inputs without a DIN attached? on the J8/9 Connector, or even at the STM32f4?

tried with 3 different DIN - all the same. i connected the DIN without a ribbon cable. after connecting (with single wires) RC2, SC and SI on J9 of the core to the same pins on DIN, and by pullig SI in and out i get random messages in MIOS: [19138.934] MBNG_DIN_NotifyToggle(102, 0) [19138.934] No event assigned to BUTTON hw_id=102 [19138.943] MBNG_DIN_NotifyToggle(102, 1) [19138.943] No event assigned to BUTTON hw_id=102 [19141.001] MBNG_DIN_NotifyToggle(143, 1) [19141.001] No event assigned to BUTTON hw_id=143 [19141.001] MBNG_DIN_NotifyToggle(157, 1) [19141.001] No event assigned to BUTTON hw_id=157 [19141.548] MBNG_DIN_NotifyToggle(177, 1) [19141.548] No event assigned to BUTTON hw_id=177 [19142.082] MBNG_DIN_NotifyToggle(6, 0) [19142.082] [EVENT] id=BUTTON:6 hw_id=BUTTON:6 bank=0 fwd_id=LED:6 type=NoteOn value=0 label=^std_btn [19142.082] MBNG_DOUT_NotifyReceivedValue(6, 127) [19142.082] MBNG_DIN_NotifyToggle(31, 1) [19142.082] [EVENT] id=BUTTON:31 hw_id=BUTTON:31 bank=0 fwd_id=LED:31 type=NoteOn value=0 label=^std_btn [19142.082] MBNG_DOUT_NotifyReceivedValue(31, 0) [19142.091] MBNG_DIN_NotifyToggle(6, 1) [19142.091] [EVENT] id=BUTTON:6 hw_id=BUTTON:6 bank=0 fwd_id=LED:6 type=NoteOn value=127 label=^std_btn [19142.092] MBNG_DOUT_NotifyReceivedValue(6, 0) switch should be standard, swapping the pins didn't help...

Ok, MBNG loaded, set debug on is showing values when i send midi to the DOUT [5328.903] set debug on [5328.905] Debug mode turned on [5333.689] MBNG_DIN_NotifyReceivedValue(1, 107) [5333.689] MBNG_DOUT_NotifyReceivedValue(1, 107) [5333.921] MBNG_DIN_NotifyReceivedValue(1, 0) [5333.921] MBNG_DOUT_NotifyReceivedValue(1, 0) still no luck on getting values when a button is pressed at DIN...

hey, thank for your quick answer. i get (running on MIDIO128) : [32819.690] set debug on [32819.692] Unknown set parameter: 'debug'! ?

Christmas time is time to get some serious projects started! Hi, my name is Roberto this is one of my bigger DiY project and my first post here. first of all, this is a very cool platform, well documented and really expandable. what i was looking for! I bought a MBHP CORE STM32F4 and some modules like DIO, DOUT, AINSER64, MIDI IO and AOUT_NG. My goal is to build a midi controller to interact with an attached computer and software via usb midi. later i want to extend it to work with midi and control voltage outputs for synths/modular application. I have basic knowledge in electronics, decent soldering and some beginner programming skills. so more or less I’m a NOOB. I soldered all the boards except MIDI IO and AOUT_NG and made some tests and detected that i have PROBLEMS WITH THE INPUTS. Although i am able to send midi notes to the DOUT and light LED’s, I’m not able to get any inputs from the DIN (with buttons) nor AINSER64 (with faders). So, i’m stuck here right now and have some questions about it: The SD-Card Holder (and the SD Card) is missing on the MBHP Core, because i still wait for it to be delivered. Is it crucial to have it soldered? And, i didn’t planed to attach a LCD. Is it needed to make the whole thing work? here is what i did until now: checked for shorts checket IC, caps and cable polarity installed bootloader and firmware: https://www.dropbox.com/s/mg1oudmpp6ekajq/bootloader_firmware.png?dl=0 installed MIOS : https://www.dropbox.com/s/fo84lnr3t7h8610/mios.png?dl=0 installed MIDIO 128 V3 : https://www.dropbox.com/s/yhp1phjezwotdgx/midiio128.png?dl=0 checked DOUT with a RGB LED: https://www.dropbox.com/s/5txs634ny5yjple/RGBLED.mov?dl=0 checked DIN : https://www.dropbox.com/s/3p5clopkz8eivwl/DIN.jpg?dl=0 The button is attached to J3 (VS - D0) of a DIN module. I can’t see any incoming messages in MIOS Studio… Can i measure the functionality with a multimeter? All i see is a drop from 4.8v to 0v at pin 11 of IC1. But i guess it’s not possible to use a multimeter to measure the serial output… The same with AINSER64, Pot attached to VS - VD on the sides and A0 on the middle, no messages on the MIOS Studio terminal… The green LINK LED stays lit on the AINSER64, so i guess some communication is missed somewhere. I searched for solutions all over the site and i didn’t find any satisfying answer. did i miss something? all the best and cherry friskmas roberto
