error_code SMADCSetSignal(u_int8 PortNr, u_int8 channel, process_id procID, signal_code sigCode);

Description

This function defines the code of the signal that is sent by the HW task when the conversion of the channel is ready. The signal is sent to the process with the ID procID. If sigCode is set to 0, no signal will be sent (disable sending of signals).

Input

u_int8 PortNr

u_int8 channel process_id procID signal_code sigCode

Port number of SM-THERM to set the signal (from 0 to 10)
