Syntax
error_code SMADCGetPrecision(u_int8 PortNr, u_int8
channel, u_int16 *pBuffer);
Description
This function checks if an SM-THERM board is fitted on the specified port
and if the channel is valid. It gets the precision/filter setting of the AD
Converter and stores the value in a user defined buffer. The user has to take
care that there is enough space to store the data.
Input
u_int8 PortNr
Port number from which to get data
(from 0 to 10)
u_int8 channel
Number of specified channel (0 to 3)
u_int16*pBuffer
Pointer to a user defined buffer

error_code SUCCESS
E_MNF
If wrong type of module or no module
is fitted on the selected port
E_PARAM

or standard OS-9 error code (refer to the OS-9
Technical Manual Error Codes Section).
