display-text
amperka/segm8/display-text
A text string to display. The string should consist of next characters: "0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "A", "b", "C", "d", "E", "F", "G", "H", "I", "J", "L", "O", "P", "q", "r", "S", "t", "U", "Y", space, dot , "-" , "[", "]", quote, double quote, underscore, degree. Instead of unsupported characters, the overline is displayed. The dot "." character does not occupy the entire segM8 module.

DEV@/segm8-device
The SegM8 device.
TEXTstring
Text to be displayed on the daisy-chain of indicator modules.
POSnumber
In a daisy chain, the ordinal SegM8 module number from which the text display begins. The module numbering in a daisy chain starts from 0, from left module to right.
Wnumber
The width of the displayed text in segM8 modules.
UPDpulse
Triggers a new display of the text.
DONEpulse
Pulses when the display of the text is done.
