Syntax

error_code SMADCGetGain(u_int8 PortNr, u_int8 channel, u_int8 *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 gain amplifier setting of the ADC and stores the value in a user defined buffer where the user has to take care that the buffer is large enough to store the data.

Input

u_int8 PortNr

u_int8 channel u_int8 *pBuffer

Output

error_code

Example

Port number to fetch the gain setting (from 0 to 10)

Number of specified channel (0 to 3) Pointer to an 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).
