error_code SMADCGetPrecision(u_int8 PortNr, u_int8

channel, u_int16 *pBuffer);

This function checks if an SM-PT100 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.

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

If wrong channel number is specified

or standard OS-9 error code (refer to the OS-9

Technical Manual Error Codes Section).

RetVal = SMADCGetPrecision(0, 1, &Buffer);
