SPLogger: Setting up what to monitor

The top pane of the SPLogger display is where you select which RAM locations you wish to monitor, and what format you want them logged in.

The pane contains a separate selector button for each RAM location. To set up a RAM location for monitoring you select it, then on the left you chose how you want it logged. The choices are:

Decimal. The data from this location will be recorded as a 3 digit decimal number in the range "000" to "255". We include leading zeros to make the output a bit easier to read.

Hexadecimal. The data from this location will be recorded as a 2 digit hexadecimal number in the range "00" to "FF". We include leading zeros to make the output a bit easier to read. Note that logging in hex format may be of limited use for use in a spreadsheet.

Bin. The data from this location will be recorded as 8 binary numbers "0" or "1". That means it will occupy 8 columns in a spreadsheet. The first column will be bit 7, the last column will be bit 0.

FP. The location is combined with the next three and interpreted as a floating point number. Note that you cannot also log the other bytes on their own. Floating point only works for addresses <124.

None. Turns off logging of the selected byte.

Trigger byte. One byte can be selected as the trigger byte. That means data will be logged only when that byte changes in the SPLat board. You would use that feature in conjunction with a SPLat program that changes the trigger bytes when it wants data to be logged. The alternative is to let SPLogger log data at regular, timed intervals, which is set up from the Control Pane.
