A constant named
that can be used for storing data logged during a round. In this example,
$150. The
Memory Map uses hexadecimal values. This makes it convenient to view the Memory
Map and decide how much memory you have available for datalogging. $10 (decimal-
16) is subtracted from
storing records will begin at EEPROM address $10.
#IF DATALOG_MODE > 0 #THEN
#ENDIF
Recall from Chapter 2, Activity #1 that converting from hexadecimal to decimal involves
multiplying the rightmost digit by 16
16
the decimal equivalent. For example, the decimal equivalent of $150, is: (1 × 256) + (5 ×
16) + (0 × 1) = decimal 336.
It's more convenient to declare
the way the EEPROM map displays all its addresses. Figure 5-4 shows the EEPROM
map for the next example program compiled with
EEPROM value not occupied by PBASIC program tokens is $257. Since records will be
stored as word values, each record will take up 2 bytes, and
Therefore,
