yes the ngc format is so much easier to go through than the old assembly!! but i got to grips with that in the end. I am trying to get to grips with everything then apply it in the thread in a more simplistic way for those coming in new and also it helps me visualise things better. I just got the fader working on the core once it was written it was simple # AIN hardware AIN enable_mask=10000000 ( I am assuming that the 8 digits refer to the 8 pins on J5a/b and for an active pin you put a 1 in place? # EVENTs EVENT_AIN id= 1 type=CC chn= 1 cc= 16 range= 0:127 It works but i get double figures in mios studio when i move the fader such as Chn# 1 CC# 16 = 22 Chn# 1 CC# 16 = 22 Chn# 1 CC# 16 = 23 Chn# 1 CC# 16 = 23 Is this a bit resolution that i need to add into the ngc code to prevent the doubling up on the fader movement into mios studio? Thanks I need some zzz now so will test the code tomorrow

Yes i understand the "bank" setup and hw id's, it was just finding an example of setting up the fader on j5a as the only other time i have used it is with an ainser64 and i dont need one of those right now. sat going through the ngc info again to see whats what, there is so much missing info wise that was never added along with the solution to having multiple ssd1306 but it still refers to j28 on the lpc pcb and nothing for the stfm pcbs. it would be good to get some of these updated as others have had to edit mios rather than configuring the ngc which is easier for users.

We need the site admins to check in with the hosts to see whats going on as the forum is having daily errors now. tonight along with the internal server error 500 that most get I am now getting the nginx error page and this is constantly every couple of mins.

Question: I want to test the bank code i have written, I am going to assign in to a fader connected to j5a on the stfm core. Would i use the EVENT_AIN function for this? I just want to connect a fader directly to j5a, so how would i implement this rather than using an ainser8 or ainser64? thanks

yes this is what is in the git hub, i am thinking of two buttons, -bank and +bank, i am still reading things and writing bits down to work on this week Thanks for the info Thomas @totoRaymond

I am looking at the banks and other functions today. I am sure I have seen this discussed somewhere ( having a forum search to find it) can you have multiple control parameters on a fader, potentiometer or encoder from a button press So if you want one fader to control ADSR features. on its 1st function its cc16 assigned to the amplitude press a button and then its second function is cc17 assigned to decay press again third function is cc18 assigned to sustain.. and so on Would this be a combination of mapping and radio buttons? I am playing around with the code today seeing if i can make a happy accident. I am currently reading the enc_banks on teh git hub https://github.com/midibox/mios32/blob/master/apps/controllers/midibox_ng_v1/cfg/tests/encbanks.ngc Tx

Question, i have 8 oleds hooked upto the st core, the first 7 work fine but the 8th keeps corrupting, it will not display the text correctly. the lcd number in the mios setting is for 8 only, i just erased the st board and re uploaded mios and the mb ng software, all is good but 8 is still garbled, i used other oleds i have here incase it was faulty, moved it around and i also got my two spare st boards and programmed them also. Still the same barled text on number 8 only, any ideas? The pcb is clean and soldered correctly no bridges or any issues. Update: Problem solved, needed more voltage so moved the j15_S from 3v3 to 5v

sorry it took so long to answer this for you. I am looking at the soldering on the rear and I can see that some of the pic socket pins are not soldered correctly to the pads and some not at all it seems. reflow the lot on the back, just place your soldering iron on the pad and push some solder in gently to flow better. Get some isopropyl alcohol from RS or Farnell etc to give the board a clean then.

@Phatline Thanks for the reply, thats a little beyond my scope messing with mios, I am good with the ng code structure. It is a shame that the MB_NG user manual section on hooking up the ssd displays was not updated in relation to the discovery boards. The reference of using J28 being the older lpc17 MB and not relating to the discovery pcbs most are now using. Perhaps it's something @TK. could give us some info about when he has time to do so, I understand he is in here very little these days but hopefully, this is one of the outstanding issues that can be resolved. Thanks again for your help both most appreciated

Thanks for the heads up @latigid on, hopefully @Phatlinecan give me some more info, I can add it to my thread along with some pics. I am just using the ssd1306 oleds. But at some point a controller with several clcd's will be on the cards

just saw this, I am working on a controller and would like to bump it upto 16 displays, when i go into bootlader and enter the number of displays as " set lcd_num_x 16 " does this mean that i can pick up the extra Cs lines from J10B without changing anything else and still use the standard control surface on J10A Just hook the displays up as i have on the first 8? each display having its own cs line. Thanks

As soon as I have some free time I will edit it and run it again.

The text is no good, it's plain lines and not a scan engrave text soi need to edit it. The lines are single lines and also not etch able these need editing also. The numbers are the same. Other than that it is OK. Just needs cleaning.

Hi Smithy Yes there is dual colour laser material, we use it. we dont use a real thick one, its about 1.5mm thick. The atacam removes the text or graphics from the top layer of black using a scan feature, then does all the cuts through. I am in the middle of hacking two old mackie control units, to make a custom controller. This is for doing a test fit for the boards. I am in next week so i will do a small section of the panel for you to see how it comes out.

I messed with kicad a long time ago, i got into eagle more and really got to grips with that, exporting the gerbers over into flatcam for milling pcbs on a small cnc machine. These days i use Altium everyday and also Solidworks pcb which has a cut down version of Altium in. Altium has the Solidworks Connector extension installed and i run a local SVn server that allows me to push the altium pcb through into solidworks directly, that way i can edit the enclosures around the pcb and push back and fore, If i move a part on the pcb in Solidworks and push back to Altium it shows me the change and allows me to re-edit the traces/Layers etc and then push back. I never upgraded my Eagle, i still have the old V7 cadsoft version, dont like the new version at all.

been busy working on various projects, finally got time to print the enclosure for one of them this weekend. Designed in solidworks and printed in Carbon/Nylon. I have 5 alps motorised faders to fit and a few buttons, leds and pots to go on a pcb i am milling next week. There are insert faceplates to do yet on the fader face and the upper face. All is looking good though so far and the cade is working as well, I am also making a small dout x2 pcb as well as i only need 9 leds, i am using a TSSOP16 74hc595 and a smt resistor network to reduce the size for the space i need in the enclosure. Using jlcpcb in china for a couple of different boards as they are far too expensive to be made in the uk.

Hey Smithy, i have an Atacam laser system in work i use, do you have this as a dxf file? i can do a panel test when i call in next week. I can do a cut on some 2, 3 or 4mm laser acrylic and see how it comes out. I can set the text to scan engrave and the rest to cut, probably take a couple of mins.

Is it possible to change the font size when using the ssd1306 oled's? Is this set in mios studio while the stf32m is in bootloader mode. when entering the , set lcd_type etc? UPDATE: I found the section i needed in the NG usermanual. GLCDs can output different fonts which are selected with the ampersant (&) character: &&: outputs the & character &<font>: selects a font for graphical LCDs: &n: selects the "normal" 6x8 font &i: selects the inverted 6x8 font &s: selects the "small" 4x8 font &t: selects the "tiny" 4x8 font &b: selects the "big" 24x16 font &k: selects "knob icons", a 24x32 font. Values can be output with %B &h: selects a meter with horizontal orientation, a 32x8 font. Values can be output with %B &v: selects a meter with vertical orientation, a 8x32 font. Values can be output with %B And finally it's also possible to change the output LCD and position within a label: @(<lcd>:<X>:<Y>): changes to the given lcd, X and Y position. Example: lcd_pos=1:1:1 label="Enc%3i&k@(1:1:2)%B&n@(1:18:1)%3d" No, this is not an encrypted message, because the processing rules are well documented! ;-) - it will output "ENC" + the ID number. Then it will select the "knob" icon, jump to position X=1 Y=2 and output the knob icon based on the EVENT value. Thereafter it will select the normal font, jump to position X=18 Y=1 and output the MIDI value in decimal format. all is good

For me here in the UK the pricing and MOQ meant that i had to get a lot of things either from ebay or ali express as the pricing in the UK was far too much. For example i wanted some 6mmx6mm square led tact switches, in the UK they were almost $5 each equivalent. I got them from Ali express for $10 for 20 of them. same with the mini 7 segments, encoders and components. In the UK its V.A.T on everything, then customs etc and forwaring postage costs with VAT added. I just got a quote in for one of my pcbs, its a 4 layer pcb 250mmx250mm it was £90 for the pcb and then a further £140 for the processing, jlcpcb in china quoted me under £100 for 5 of the pcbs with shipping etc. I rarely get anything from the UK side anymore.

perhaps you need to look at the blm then?

hmm.. i probably ask more questions that I already know the answer to.. it just takes me a little while to catch up with my brain. So i am looking at the question, so am i correct in you want to build a controller to control a drum machine plugin in logic? Please bear in mind I dont use logic i use presonus studio one, i havent turned my mac on in years and its an old G4 mirror door!! You could have a look through my thread in the MBNG section, it shows me learning the basics and progressing slowly, making mistakes and asking for help. I dont always understand it straight away but I get there eventually as it shows as I progress. If I can help I will, otherwise the other members will step in I am sure ;) @latigid on ;) One thing try using a good powered usb hub and plug your mbng into that, thats how i am running mine.
