Properties |
|
Connections |
|
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. | |
|
TX |
| Pin to be used for Transmit data | |
|
|
RX |
| Pin to be used for Receive data | |
|
|
Use Flow Control |
| Flow Control (Handshake) enable or disable. On: Two I/O pins are used to control the flow of data in and out of the device. Off: Flow control is disabled. | |
|
|
Baud Options |
| Baud rate option selector | |
|
