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.
DOW:
Dallas One-Wire protocol, similar to I2C, provides reduced data rates at a greater distance. One
wire carries data, while two others supply power and ground. Matrix Orbital tests non-parasitic devices
only, those that do not draw power from the data line; however, some parasitic devices may work.
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.
I2C:
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.
RS422:
Recommended standard 422, a more
robust differential pair serial protocol.
SDA:
Serial data line used to transfer data in I2C
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 I2C
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 pass light. In an excited state these crystals align to block light.
Super-twisted crystals move from 180 to 270 degrees between to increase
contrast over
TN models.
TTL:
Transistor-transistor logic applied to serial protocol. Low level is
0V while high logic is 5V.
