Description
Measure the voltage of an analog input pin.
The Time Multiplexed Analog to Digital Converter (TMADC) block outputs the voltage as
a 12-bit value and the output port is an array N x 1
where
N is defined based on the number of channels selected.
Ports
Input
trigger — Port to trigger the conversion
scalar
Triggers the TMADC input pin for conversion via software trigger.
From trigger port when mode is set trigger only enables you to provide the sample time.
1—
TMADC start of conversion is triggered0—
TMADC start of conversion is not triggered
Dependencies
To view this port, set the Mode parameter to
Trigger only
.
Data Types: single

msg — SoC Blockset simulation message
scalar
This port receives SoC Blockset™ message from the interface blocks and the TMADC block converts this message and outputs it at the result port during simulation.
Dependencies
To view this input port, set the Mode to
Trigger and read
or Read
results only
and select the Enable
simulation port parameter and set the port type as
SoC Data (Message based).
sig — Simulink based simulation signal
scalar
| vector
The simulation-only Simulink® signal input port acts as a pass-through for the output of the TMADC block during simulation.
Dependencies
To view this port, set Mode to
Trigger and read
or Read
results only
and select the Enable
simulation port parameter and set the port type to
Signal.
Output
result — Voltage as 12-bit value
scalar
| vector
The block outputs the voltage as a 12-bit value and the output port is
an array N x 1
where N is
defined based on the number of channels selected.
Dependencies
To enable this port, set the Mode parameter
to Trigger and read
or Read
results only
.
Data Types: uint16
status — Status of read operation
scalar
The block outputs the status of read operation at this port as one of these values:
0—
No error in reading the result after successful trigger for the corresponding channel1—
Error in reading the result after successful trigger for the corresponding channel
Dependencies
To enable this port, set the Mode to
Read results only
and select the
Enable status port parameter.
Data Types: double
timestamp — Status of 16-bit counter value
scalar
| vector
The port outputs the status of the 16-bit counter value of timestamp counter.
Dependencies
To enable this port, select the Enable timestamp parameter.
Data Types: Boolean
event — Event message to start conversion
scalar
This port outputs an event message at each trigger to start the conversion during simulation.
Dependencies
To view this port, set the Mode to
Trigger only
and select the
Enable simulation port parameter, and set
the port type to SoC Data (Message
based).
triggersig — Simulink based trigger signal for simulation
scalar
| vector
This port outputs the data received at trigger input port as a signal during simulation.
Dependencies
To view this port, set the Mode to
Trigger only
and select the
Enable simulation port parameter, and set
the port type to Signal.
Parameters
Mode — Operation mode of the block
Trigger and read
(default) | Trigger only
| Read results only
Select one of these operation modes:
Trigger and read—
Select this option to trigger conversion at every sample time. The block waits until the conversion is complete and outputs the results. This option enables the output port result.Trigger only—
Select this option to trigger the selected channel via a software trigger. This option enables the input port trigger. As the block does not show the conversion results in this mode, you have to use another TMADC block with the Mode parameter set toRead results only
to display the conversion results.Read results only—
Select this option for the block to read the result at the selected channel. The block outputs0
at the status port if it is able to read the result and1
otherwise. This option enables the output port result.
Number of channels — Select required channels
1
(default) | 2
| 3
| ...
If you set the Mode to Trigger and
read
, then select the required number of channels ranging
between 1
through 16
. The number of
channels are limited to 1 if you set the Mode to
Trigger only
or Read results
only
.
Enable timestamp — Enable timestamp
off
(default) | on
Select to enable the timestamp.
When you select the Enable timestamp
parameter, the
block configures an additional output port, timestamp similar to result port
to read the timestamp.
Note
TMADC module has 16-bit timestamp counter which resets after every counter overflow.
Enable timestamp parameter is not available when mode is set to
Trigger only
.
Enable status port — Configure status port
off
(default) | on
When you select this parameter, the block configures the status output port. The status port outputs the status of the conversion result.
Dependencies
To enable this port, set the Mode parameter to
Read results only
.
Sample time — Frequency at which block reads input analog pin(s)
-1
(default) | scalar
| vector
Specify in seconds how often the block should read the analog pin(s).
When you specify this parameter as -1
, Simulink determines the best sample time for the block based on the
block context within the model.
Dependencies
To enable the Sample time parameter, set the
Mode parameter to either Trigger
and read
or Read results
only
.
Enable simulation port — Enable peripheral simulation ports in the block
off
(default) | on
Select this parameter to enable peripheral simulation capability.
Note
If you do not have a SoC Blockset license, the Enable simulation port parameter is visible but you cannot enable it.
Port Type — Specify the type of peripheral simulation port
SoC Data (Message based)
(default) | Signal
Select this parameter to configure either the SoC Blockset compatible or the Simulink signal based simulation ports to enable peripheral simulation capability.
Dependencies
To view this parameter, select the Enable simulation port parameter.
