Hello everybody, These are some design Questions! I was wondering about assembling some midibox modules to achieve a little graphical ocilloscope to watch my audio/CV like in this vid : https://www.youtube.com/watch?v=utr23hp2nRM (like on the 4 OLED screens) - I think a great part the work is already accomplished if TK already realized that. Am I Wrong? - What is the exact voltage range of the Core32 DACs ?. Edit : From The Ucapps Page STM32F4 Core module : 0-3.3V for native ADC From AINSER Module Page : 0-5V - Audio Inputs Should be ok for Core32 DACs/AINSER? What about bipolar voltage?And if i have "high" voltages like for example +15/-15v , is an OpAmp setup with dividing gain of 3 ok to reduce voltage range to -5v/+5V? - What is the biggest resolution and screen size that MIOS32 already supports? (i was expecting a 5cmx5cm wide 256px*256px monochrome display or something like that) - Is the combination of Core32+AINSER8 is modules enough to support 8 analog inputs (audio/CV)? I also thought Few DIN/DOUT Serial Registers may allow to have a little Control Surface to switch between inputs and make few changes about display calibration. Please correct me if i am going in a dead end way =) Thanks in advance for your advices! Greets, Jerome

Hi, im trying to use 2 KS0108-Displays on my LPC17-Core-Board. With the Bootloader i can setup lcd_width @255 maximum, which results in one unused column at the right side of the 2nd display. has anyone experienced similar problems and what is the workaround to get all the 256 lcd-columns working properly ?? regards, mOnO

Anyone tried retro-fitting a 20x2 character OLED to the SammichSID? I recently (after Many years) rediscovered my SammichSID. It still sounds great, but sadly the original LCD has faded almost to invisibility, so I wondered if a more modern OLED would work. I've heard OLEDs can cause HF noise issues, so I'm especially interested to find out if this would be the case with a drop-in replacement of the original LCD.

The thing stopping me from making a MIDIbox Logic Control has always been the lack of suitable commercially available displays. Has anybody ever considered trying the MacBook Pro touch bar? It's a 2170x60 colour graphical OLED, and it can be bought for around 30 dollars. Maybe it would be perfect for a scribble strip for 8 faders. I have no idea if data is available for this though.... https://www.aliexpress.com/item/Original-NEW-A1706-Touch-Bar-for-Macbook-PRO-Retina-13-Inch-A1706-2016-Touchbar-Replacement/32821436004.html

Hi, I have a core built and attached displays (raystar oleds) and found them not working. On testing pin 1&2 I see I'm getting 4.2v instead of the expected 5v. Changing the J15 jumper to 3.3v only drops the voltage to 4.1V. Setting it back to 5v gives me 4.2. (this is with displays disconnected). Can anyone suggest where to go from here?

Hi Guys I have one "semi kit" for sale for the Track Position display. Ponoko Laser Cut Front and Rear Panel in Transparent Acrylic PCB 2 x LED Matrix displays 7 x Kingbright 7 seg displays (I am fairly certain they are green) 1 x knob 1 x encoder 1 x 74HCT165 Buttons, switches, BiLEDS, 74HCT595, IDC header and SMD passives are missing - I simply never got round to building it up. PM me if interested. Please make an offer on PM (ideally I am looking for £30 GBP, buyer pays Postage/Paypal fees. kguy<dot>wilkinson<at>gmail<dot>com Please dont reply with offer on this page. Cheers Guy

Looking for 2 pcs of Futaba M402SD10FJ vfd displays. Have tried Mercateo but no success.
