| - VOID
|
Return |
VisiReadByteFromMessage
|
|
VisiReadByteFromMessage |
| Reads a byte from a succesful VisiReceive macro. Index: 0=Command, 1=ObjectID, 2=ObjectIndex, 3=ValueMSB, 4=ValueLSB | |

Properties |
|
Comms Settings |
|
Channel |
| UART Channel selector Software channels are bit banged using generic I/O pins but are not as reliable as hardware channels. Hardware channels use the selected peripheral on-board the target microcontroller. | |
|
|
Baud Options |
| Baud rate option selector | |
|
Baud Rate |
|
|
Connections |
|
TX |
| Pin to be used for Transmit data | |
|
|
RX |
| Pin to be used for Receive data | |
|
|
Simulation |
|
Label |
| Label shown on the communications flasher component | |
|
Scope Traces |
| Selects if the scope traces are automatically added to the data recorder window or not. Simulation - draws an approximation of the UART data onto the scope trace. ICT - sets up the scope trace for incoming data and adds UART packet decoding at the correct BAUD. | |
|
|
Console Data |
| Selects if the console data is automatically generated or not | |
|
Console Columns |
| Number of characters that can be displayed on a single line of the console. | |
|
|
Data Source |
| Simulation data source used to allow the component to connect to various remote devices Nothing - Simulation data is ignored COM port - Routes the communication data to and from a physical or virtual COM port Injector - Routes the communication data via a data injector component on the Panel. | |
