| - | ====== ENCs module ====== | + | ====== SCS OLED module ====== |
| - | Encoders illuminated with WS2812 LEDs | + | Combination of 0.96" SSD1306 OLEDs and switches for an [[http://www.ucapps.de/midibox_ng_manual_scs.html|SCS]] |
| ===== Schematic ===== | ===== Schematic ===== | ||
| - | Power input is +5V via a 3-pin 100mil connector (or Molex) and a Schottky diode. The value of electrolytic capacitor C1 is not critical. | + | Refer to the SCS schematic or below for J1/button and encoder pinning and the Core module (J15) for J5/OLEDs. |
| - | The pLED chain enters via J2:pin 6 and resistor R1. The resistor should be replaced with a wire link for each additional module (i.e. only the first in the chain gets a resistor, the remainder stuffed with wire links). The serial chain then follows a snake pattern to J3, where additional pLED modules may be connected. The LED ID matches the capacitor name. The RC (R2, C18) end termination shouldn't be necessary, but can be trialled should problems with signal reflection arise. | ||
| - | Encoders are arranged in columns with outputs on J4--7. The top encoder (EN1/5/9/13 uses pins 10/9, the second (EN2/6/10/14) 8/7 etc. Note that the direction of these encoders is opposite to that of ALPS STEC-12. This needs to be accounted for in an MB_NG config file. | + | ---- |

| ===== Versions ===== | ===== Versions ===== | ||
| - | v1.0: errata: J4--7 have no connection to ground. J1-3 do carry ground, so it isn't a problem if the DIN modules share the same power rail. | + | v1.0: first release |
| ===== Assembly ===== | ===== Assembly ===== | ||
| - | FIXME | + | |
| - | LEDs | + | Decide on the configuration to be used. Any combination of switches, encoders or OLEDs is possible if they fit. |
| + | |||
| + | Only one encoder is wired to the J1 header. If you want to use the EN2 position, wire the legs to the empty EN1 solder points. | ||
| + | |||
| + | R9 and C29 form the power-on reset for OLEDs. R7 should not be installed. R3/C25/R4/C26 form a termination shunt for OLED data lines. They shouldn't be required. | ||
| + | |||
| + | The switches accommodate either DT6 or 6mm switches (obviously only one type!). For DT6 switches, ensure the flat side is aligned with the PCB silkscreen. | ||
| + | |||
| + | J2 can supply power if needed. | ||
| + | |||
| ==== Interconnections ==== | ==== Interconnections ==== | ||
| - | FIXME | ||
| - | * J2 normally connects to Core J4B (I2C) | ||
| - | * J3 carries the WS2812B chain for additional modules | ||
| - | * J4 connects to a DIN header | ||
| - | * J5 connects to a DOUT header | ||
| + | {{::scsoled:j1.png?nolink&200|}} | ||
| + | |||
| + | J1 is the SCS header, connecting to J10A | ||
| + | |||
| + | J2 can provide power as indicated; it is also connected on J5. | ||
| + | |||
