int anaSaveCalib(int boardtype);
The calibration constants may also be saved in the flash memory on the Smart Star CPU Card. Doing so
will speed up D/A conversions since a memory access from flash memory will be faster than from
EEPROM. Use anaSaveCalib to save the current set of calibration constants for the analog input or
output channels in the Smart Star flash memory. The calibration constants stored in flash memory can
then be accessed at any time with the anaLoadCalib function.
Calibration constants should first be established using anaOutCalib or obtained via anaOutEERd .
PARAMETER
boardtype is the type of board, which is 0 for the D/A Converter Card, 1 for the A/D Converter Card.
RETURN VALUE
0 if successful.
–1—attempt to write non-flash area, nothing written.
–2— rootSrc not in root.
–3—timeout while writing flash memory.
–4—attempt to write to ID block sector(s).

int anaLoadCalib(int boardtype);
Reads a complete set of calibration constants for the analog output channels from the Smart Star flash
memory on the CPU Card. These should have been loaded to the flash memory with the anaSaveCa-
lib function.
PARAMETER
boardtype is the type of board, which is 0 for the D/A Converter Card, 1 for the A/D Converter Card.
RETURN VALUE
0 if successful.
–1—attempt to read from non-flash area.
–2—destination not all in root.
