Command Summary 32

9 Definitions

ASCII: American standard code for information interchange used to give standardized numeric codes

to alphanumeric characters.

BPS: Bits per second, a measure of transmission speed.

FFSTN: Double film super-twisted nematic in reference to an LCD. The addition of two layers of film

between the STN display and polarizer improves contrast.

GPO: General purpose output, used to control peripheral devices from a display.

GUI: Graphical user interface.

Hexadecimal: A base 16 number system utilizing symbols 0 through F to represent the values 0-15.

C: Inter-integrated circuit protocol uses clock and data lines to communicate short distances at

slow speeds from a master to up to 128 addressable slave devices. A display is a slave device.

LSB: Least significant bit or byte in a transmission, the rightmost when read.

MSB: Most significant bit or byte in a transmission, the leftmost when read.

RS232: Recommended standard 232, a common serial protocol. A low level is -30V, a high is +30V.

SDA: Serial data line used to transfer data in I

C protocol. This open drain line should be pulled high

through a resistor. Nominal values are between 1K and 10K Ω.

SCL: Serial clock line used to designate data bits in I

C protocol. This open drain line should be pulled

high through a resistor. Nominal values are between 1K and 10K Ω.

STN: Super-twisted nematic in reference to an LCD. In a relaxed or nematic state, crystals orientate

themselves in the same direction and allow light to pass. In an excited state these crystals align to block

light. Super-twisted crystals move from 180 to 270 degrees providing greater contrast than TN models.

TTL: Transistor-transistor logic applied to serial protocol. Low level is 0V while high logic is 5V.
