This is an overview of abbreviations and acronyms used frequently at midibox.org. Many of these are also useful if you want to program in C or work with the function overview listings of MIOS:
| Acronym | Meaning | Description |
|---|---|---|
| AIN | Analog INput | A module which accepts input of a Voltage Range (normally 0 to +5 V) |
| AOUT | Analog OUTput | A module which outputs a Voltage Range (norm. 0 to 5 or 12 V) - also known as CV (Control Voltage) Outputs |
| ASM | ASseMbly Language | |
| BCD | Binary Coded Decimal | The three chars '1','2','7' represent the BCD of the integer 127 |
| BS | BankStick | Non-volatile memory module based on the 24LC256 / 24LC512 EEPROM |
| CAN | Controller Area Network | Interface used to control up to 3 additional synths from the same frontpanel of MBSID V2. See http://www.ucapps.de/midibox_network.html |
| CLCD | Character Liquid Crystal Display | Displays Characters (see also GLCD) |
| DIN | Digital INput | Binary state input (ON/OFF), normally used for buttons |
| DOUT | Digital OUTput | Binary state output (ON/OFF), normally used for LEDs |
| EEPROM | Electrically-Erasable Programmable Read-Only Memory | |
| ENC | ENCoder | Similar in operation to a Pot (potentiometer), sometimes called a “relative” or “digital” pot, in-/decrementing single steps |
| Gnd | GrouND | Common wiring point, typically a 0V Reference. See Vss |
| GLCD | Graphical Liquid Crystal Display | Pixel based Display (see also CLCD) |
| HLP | HeLP / Higher Layer Protocol | |
| IIC/I2C | Inter-IC | Language Protocol often used for inter-microcontroller-communication |
| LCD | Liquid Crystal Display | |
| MBHP | MIDIBox Hardware Platform | If the MIDIbox was a PC, this would be the motherboard |
| MIOS | MIDIBox Operating System | If the MIDIbox was a PC, this would be windows |
| MF | Motor Fader | |
| MPROC | MIDI PROCessing Routine | |
| PWM | Pulse Width Modulation | 1) A function provided by the MIDIbox SID to produce fat pulse sounds — or — 2) Allows to control a voltage level by pulsing a binary digital signal (ON/OFF) through a low-pass filter (e.g. a resistor/capacitor pair — or a motor fader) |
| SR | Shift Register | |
| SRIO | Shift Register Input/Output | MIOS scans the DIN and DOUT Shift Registers in parallel, this combination is mostly abbreviated to SRIO |
| Vdd/Vcc | Voltage Drain/Collector | Positive Voltage eg: +5V regulated supply. Voltage measured relative to Vss. Regulation is typically done on the Core board. Name refers to 'draining' or 'collecting' electrons (negatively charged) from the circuit. |
| Vss/Vee | Voltage Source/Emitter | Negative Voltage eg: 0V Reference. Also called “Ground”, “Gnd”, “Shield”, and less often, “Earth” or “Chassis”. Usually in an audio application, the 0V line is connected to the chassis. This 0V line is particularly susceptible to noise, so care should be taken with wiring this line. Name refers to the 'source' 'emitting' electrons (negatively charged) into the circuit. |
