LCDbar_INC.bas is an Include file that makes it easy to create BARgraphs on your LCD display.
Features:
- Can be placed anywhere on the screen.
- Can be any width (whole characters)
- Can be scaled anywhere between 0 and 32768.
- Three styles to choose from.* {lines, boxed, blocks}
- Just 1 Command does it all. (Well, sort of)
If using a 4x20 display, you can use this define to let the program know the addressing is different. * Thanks, CocaColaKid!
DEFINE LCD4X20 1
Here's an example of a BARgraph that follows an A/D input.
; Initialize your hardware and LCD first.
DEFINE ADC_BITS 8 ' Number of bits in ADCIN result
ADCON1.7 = 1 ' Right Justify AD result
INCLUDE "LCDbar_INC.bas" ' Include the BARgraph routines
Value VAR WORD ' Must be a WORD even though AD is 8bit
LCDOUT $FE, 1 ' Clear Screen
Loop1:
ADCIN 0, Value
LCDOUT $FE,2,"Value=",DEC Value," "
; syntax- BARgraph Value, Row, Col, Width, Range, Style
@ BARgraph _Value, 2, 0, 16, 255, lines
GOTO Loop1
This is just like the previous example except that it places both the Value and the BAR on the same line.
; Initialize your hardware and LCD first.
DEFINE ADC_BITS 8 ' Number of bits in ADCIN result
ADCON1.7 = 1 ' Right Justify AD result
INCLUDE "LCDbar_INC.bas" ' Include the BARgraph routines
Value VAR WORD ' Must be a WORD even though AD is 8bit
LCDOUT $FE, 1 ' Clear Screen
Loop1:
ADCIN 0, Value
LCDOUT $FE,2,DEC Value," "
; syntax- BARgraph Value, Row, Col, Width, Range, Style
@ BARgraph _Value, 1, 4, 12, 255, lines
GOTO Loop1
