5.3.8.15 SMADCEnableConversion
Syntax
error_code SMADCEnableConversion(u_int8 PortNr, u_int8
channel, BOOLEAN enable);
Description
This function checks if an SM-THERM board is fitted on the specified port
and if the channel is valid and forces the HW task to convert the raw values.
If the flag enable is TRUE (<>0), then conversion of raw values to degrees
Celsius is executed, else if (enable=FALSE) no conversion takes place. The
function invalidates converted data, if enable is set to FALSE.
Input
u_int8 PortNr
Port number to enable data conversion
(from 0 to 10)
u_int8 channel
Number of specified channel (0 to 3)
BOOLEAN enable
Flag for enabling or disabling conversion of
raw values
Output
error_code SUCCESS
E_MNF
If wrong type of module or no module
is fitted on the selected port
E_PARAM
If wrong channel number is specified
E_BMODE
If conversion can’t be enabled because
a bad or no sensor type is specified
or standard OS-9 error code (refer to the OS-9
Technical Manual Error Codes Section).
Example
RetVal = SMADCEnableConversion(0, 1, FALSE);
