error_code SMADCGetPrecision(u_int8 PortNr, u_int8 channel, u_int16 *pBuffer);

Description

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.

Input

u_int8 PortNr

u_int8 channel u_int16*pBuffer

Output

error_code

Example

Port number from which to get data (from 0 to 10)

Number of specified channel (0 to 3) Pointer to a user defined buffer

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).
