Collecting Binary-Formatted HLL Data using BIN_HLL.BAS
The following program, BIN_HLL.BAS, in the EXAMPLES directory will set up the ChartScan to collect
High/Low/Last channel readings in a binary format rather than the default ASCII format. This is inherently
faster than ASCII format, but the data must be deciphered after it is collected to yield temperature values.
This program configures the channels, uploads HLL data in High speed binary mode, decodes this data and
displays it on the screen.
Although not necessary, it is good practice to reset the ChartScan at the beginning of your application by
sending it the “*R” command and then waiting a few seconds.
