5.3.8.11 SMADCSetSignal
Syntax
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
Port number of SM-THERM to set the signal
(from 0 to 10)
u_int8 channel
Number of specified channel (0 to 3)
process_id procID
ID of the process to send the signal to
signal_code sigCode
Signal code to be sent
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
E_SIGNAL
Illegal signal code used (it must be
⊕ 0x100)
or standard OS-9 error code (refer to the OS-9
Technical Manual Error Codes Section).
Example
RetVal = SMADCSetSignal(0, 1, 0, 0x100);
