Syntax

error_code SMADCGetSensorType(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 code of the sensor type of the specified

channel and stores it in a user defined buffer. The user has to take care that

there is enough place to store the data. A list of PEP supported sensor types

can be found in the file linear.h.

Input

u_int8 PortNr

Port number from which to fetch sensor type

(from 0 to 10)

u_int8 channel

Number of specified channel (0 to 3)

u_int16*pBuffer

Pointer to a user defined buffer

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

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

Technical Manual Error Codes Section).
