Antichambre Posted February 3, 2018 Report Posted February 3, 2018 Hello Andy, What is the CS1 original purpose? Could be fine for CS development , no? Best Bruno Quote
latigid on Posted February 3, 2018 Author Report Posted February 3, 2018 Sure, it was designed as a MBCV v2 setup working with the ENC/PAD/SR boards (the DIN6DOUT4 can stack on the rear). Other priorities for the moment, so it's on hold. TK. has even developed a HWCFG for it; it's just been on the backburner for a while... Quote
Phatline Posted February 4, 2018 Report Posted February 4, 2018 the DIN6DOUT4 has pulldown/up resistors on board? Quote
latigid on Posted February 4, 2018 Author Report Posted February 4, 2018 1 hour ago, Phatline said: the DIN6DOUT4 has pulldown/up resistors on board? Yes! It's a SOIC 165 chip on one side and a MSOIC on the other, just like in the BLM16x16+X 1 Quote
Phatline Posted February 8, 2018 Report Posted February 8, 2018 ELO: please more information about the used 2812 LEDs, which color in your Setup... it looks like you used 2x Single Color LEDs? CD? Color? - thx. Quote
Hawkeye Posted February 8, 2018 Report Posted February 8, 2018 Here is a walkthrough on the ELO boards by Andy: https://www.youtube.com/watch?v=iKZ_7VVqbFo The LEDs are RGB with an integrated controller (WS2812), fully mixable by MBNG, you can achieve many different colors. Many greets, Peter Quote
Phatline Posted February 9, 2018 Report Posted February 9, 2018 he is talking about 5050 LEDs so these for example might fit: aliexpress.. Quote
Phatline Posted February 17, 2018 Report Posted February 17, 2018 got the pcps and parts a few days ago, thx man Quote
latigid on Posted February 17, 2018 Author Report Posted February 17, 2018 Cool cool, still have to catch up on the doku... I have at least the parts guide for the 'ELO board. Quote
ganchan Posted February 22, 2018 Report Posted February 22, 2018 If still available i am interested in one of each: pads, encs, cs1, din6dout4. Quote
latigid on Posted February 22, 2018 Author Report Posted February 22, 2018 All good! Sorry, been busy! Will answer PMs/orders as soon as I can. Quote
Phatline Posted March 15, 2018 Report Posted March 15, 2018 a question to the elo-boards: what is a: TS16 R-EU_TS 0204TS how does this touchsensor look? ( i am on ordering parts...) Quote
latigid on Posted March 15, 2018 Author Report Posted March 15, 2018 0204 is just the "wire link" resistor package. Notice one of the pads is connected to the encoder body, so bridging the TS parts as drawn as a "resistor missing a side" with wire will connect the metal surface to the DIN chain. Then something like a metal washer or custom CNC part can be connected to the encoder body using the thread/nut/washer. It was done like this so that the TS functions can be separate from the encoders if needed, and also that the metal surface can be "processed." Quote
Phatline Posted March 31, 2018 Report Posted March 31, 2018 quest on disp.driver.pcb: Software-Side: is there any speciality by using the driver instead of not useing a driver? (could i just run/adapt the MB-Programmer code for example... or is there more to do?) Quote
latigid on Posted March 31, 2018 Author Report Posted March 31, 2018 Just follow the normal LCD setup by defining the desired number of displays through the bootloader app. I think the first 8 are still selected by J15, but I'm sure you could configure 64 lines using the Disp Driver CS if wanted. It may be useful to power the driver at +5V if the OLEDs are locally regulated. 1 Quote

(may 3.3 5V problems accour? see my last sentence below) hmm what about J9 - for what is that? should that be a output or a input? i dont measure voltage there... do i have to connect to core? anwhere? do you have wired already displays with that pcb? , a photo additional to wiki - would be helpful: http://wiki.midibox.org/doku.php?id=display_driver what i see, i have to paralell wire 8 displays per 2x5 socket, and single wire the cs coming from the 2x5 socket, the ground i can take from the 2x5 socket, the +Potential (in your shematic its 5V) i dont found... maybe that J9? on the 2x5 i dont found that 5vdc+. .... by the way in this document: http://ucapps.de/mbhp/mbhp_lcd_ssd1306_single_mios32.pdf the display is connected via 3.3V, in your diagram it is on +5V Quote
latigid on Posted March 31, 2018 Author Report Posted March 31, 2018 Just now, Phatline said: hmm what about J9 - for what is that? should that be a output or a input? i dont measure voltage there... do i have to connect to core? anwhere? Sorry for missing this; J9 is the power supply if you would like to supply it through the J1-8 headers. It's separate from the 3v3 supply. Just now, Phatline said: do you have wired already displays with that pcb? , a photo additional to wiki - would be helpful: http://wiki.midibox.org/doku.php?id=display_driver Here is the correct wiring (a bit messy) Just now, Phatline said: what i see, i have to paralell wire 8 displays per 2x5 socket, and single wire the cs coming from the 2x5 socket, Yes. The SPI data/clock/#DC can be shared between a few OLEDs (e.g. ELO or SCS-OLED) with a separate CS to each display. Just now, Phatline said: the ground i can take from the 2x5 socket, the +Potential (in your shematic its 5V) i dont found... maybe that J9? on the 2x5 i dont found that 5vdc+. .... Or you can power the displays directly from your PSU. Depends on the current etc. Just now, Phatline said: by the way in this document: http://ucapps.de/mbhp/mbhp_lcd_ssd1306_single_mios32.pdf the display is connected via 3.3V, in your diagram it is on +5V I think I did it this way as Core J10B is wired to 3v3 (3v0 on a Disco board). Generally the logic levels shouldn't be mixed. It's just a matter of how the display expects its data. 1 Quote
FantomXR Posted March 31, 2018 Report Posted March 31, 2018 Just a quick note: The OLEDs I received are able to run at 5V instead of 3.3V. They are also brighter at 5V. So you might not need a 3.3V reg. If you use an external 5V power supply for your cores, you are able to power them directly through this. I'm pretty sure this is valid for other OLEDs too. I order mine at aliexpress for about $3 / pc. Quote
