A/O WITH AUTO-INCREMENTING
The following BASIC program:
SETS THE BOARD TO THE AUTO-INCREMENT MODE. STARTING WITH CHANNEL 0
AND ENDING WITH CHANNEL g. IT THEN PERFORMS CONTINUOUS CONVERSIONS.
PRINTING 10 VALUES IN EACH ROW SO CHANNEL 0 IS IN THE FIRST COLUMN.
CHANNEL I IN THE SECOND. ETC.
The switches on the daughter board are set to the last channel to be
converted in the increment sequence. In this case a 9 (00001001).
lines 20 and 30 set the channel select address on the board to 255,
which is necessary since in the auto-incrementing mode this address
is automatically incremented before each conversion, making the first
channel converted channel O. The start conversion in line 30 ;s
needed since the specified channel number is not acutal'y loaded into
this register until a conversion is performed. line 40 sets the register
which holds the starting channel in the auto increment sequence to 0;
therefore, after converting channel 9. the next channel converted will
be O.
