BHT-BASIC represents the bit order by the exponent of each binary digit in the byte. For
example, bit 0 means LSB; bit 7 means MSB.
*2
The reading confirmation LED is controllable only when the bar code device file is closed.
If the file is opened, the
OUT statement will be ignored.
If you have set the confirmation LED to OFF in the
OPEN "BAR:" statement, a user pro-
gram can control the reading confirmation LED although the bar code device file is opened.
*3
Lower three bits (bit 2 to bit 0) in this byte control the contrast level of the LCD in 000 to 111
in binary notation or in 0 to 7 in decimal notation. 0 means the lowest contrast; 7 means the
highest.
OUT 3,7 ’Contrast is highest
OUT 3,&h07 ’Contrast is highest
*4
The sleep timer feature automatically interrupts program execution if no event takes place
within the specified length of time preset by bit 7 to 0. Shown below are examples of
OUT
statements. Setting 0 to this byte disables the sleep timer feature. (Refer to Chapter 10.)
OUT 6,30 ’3 seconds
OUT 6,0 ’No sleep operation
