Detailed Description

console input / output.

Author(s):: Markus L. Noga <noga@inrialpes.fr>

Warning:: Display updates are realized exclusively by lcd_refresh()

Display positions: Digit display positions are denumerated from right to left, starting with 0 for the digit right to the running man. Digit 5 is only partially present on the RCXs display.

Native segment masks: In these bitmasks, bit 0 toggles the middle segment. Bit 1 toggles the top right segment, and the remaining segments are denumerated counterclockwise. The dot isn't encoded because it is desirable to seperate its positioning from the number display code.

Function Documentation

void delay (unsigned ms)

uncalibrated delay loop.

Parameters:: ms - approximate time in ms

void cputc_native (char mask, int pos)

display native mode segment mask.

Parameters:: mask - the segment mask.; pos - the desired display position.

this is a dispatcher for the fixed position routines.

void cputc_native_0 (char mask)

display native mode segment mask at display position 0.

Parameters:: mask - the mask to display

void cputc_native_1 (char mask)

display native mode segment mask at display position 1.

Parameters:: mask - the mask to display

void cputc_native_2 (char mask)

display native mode segment mask at display position 2.

Parameters:: mask - the mask to display

void cputc_native_3 (char mask)

display native mode segment mask at display position 3.

Parameters:: mask - the mask to display

void cputc_native_4 (char mask)

display native mode segment mask at display position 4.

Parameters:: mask - the mask to display

void cputc_native_5 (char mask)

display native mode segment mask at display position 5.

Parameters:: mask - the mask to display. only the middle segment is present on the display.

void cputw (unsigned word)

display a hexword in the four leftmost positions.

Parameters:: word - the hexword

position 0 is unaffected by this call.

void cputs (char * s)

display an ASCIIZ string.

Parameters:: s - the string

only the first 5 characters will be displayed.

Variable Documentation

const char ascii_display_codes[]

ASCII display codes.

This is a 7-bit ASCII table only.
