 +====== Acronyms ======
  
 +This is an overview of abbreviations and acronyms used frequently at [[http://​midibox.org | 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_module|AIN]] | Analog INput | Input of a Voltage Range (norm. 0 to 5 V) |
 +| [[aout_module|AOUT]] | Analog OUTput | Output of a Voltage Range (norm. 0 to 5 or 12 V) - also known as CV (Control Voltage) Outputs | 
 +| [[BCD]] | Binary Coded Decimal | The three chars '​1','​2','​7'​ represent the BCD of the integer 127 | 
 +| [[Bankstick|BS]] ​ | BankStick | Non-volatile memory module based on the 24LC256 / 24LC512 EEPROM |
 +| [[CAN Interface|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 |
 +| [[lcd#​character_lcds|CLCD]] | Character Liquid Crystal Display | Displays Characters (see also GLCD) |
 +| [[din_module|DIN]] | Digital INput | Binary state input (ON/OFF), normally used for buttons |
 +| [[dout_module|DOUT]] | Digital OUTput | Binary state output (ON/OFF), normally used for LEDs | 
 +| [[EEPROM]] | Electrically-Erasable Programmable Read-Only Memory ​ |  |
 +| [[Encoders|ENC]] | ENCoder | Similar in operation to a Pot (potentiometer),​ Relative Digital Pot, in-/​decrementing single steps |
 +|[[Gnd]]| GrouND | Negative Voltage eg: 0V Reference. See Vss|
 +| [[lcd#​graphical_lcds|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. |
