That means that each pulse has to be translated to a 1 or 0, and then the corresponding bit
position in a variable has to be set or cleared.
The
making it possible to select individual bits in a given variable.
Let's say that you have a byte variable named
bit-6. Here's a way to do that with the help of the
The next example program demonstrates how to use the
bits in a byte variable with the help of the Debug Terminal's Transmit and Receive
Windowpanes. It uses three variables, a byte named
a bit named
command, you can pick any bit in the
zero with these commands:
.BIT
value.BIT5 = 0
value.BIT6 = 1
DEBUGIN DEC1 index
DEBUGIN BIN1 setClear
IF index = 0 THEN value.BIT0 = setClear
IF index = 1 THEN value.BIT1 = setClear
IF index = 2 THEN value.BIT2 = setClear
IF index = 3 THEN value.BIT3 = setClear
IF index = 4 THEN value.BIT4 = setClear
IF index = 5 THEN value.BIT5 = setClear
IF index = 6 THEN value.BIT6 = setClear
IF index = 7 THEN value.BIT7 = setClear

This technique cannot be used in the upcoming IR remote examples because it would
require more calibration with the IR remote pulse measurements. Even so, it's a worthwhile
exercise to replace the eight
