UARTs interface[edit | edit source]
Description[edit | edit source]
The UARTs interfaces available on the RIALTO SBC are mapped to the following connectors:
- J66 is a Phoenix 282837-3 3x50.8mm connector. On this connector are mapped these instances: UART3 or CAN.
- J67 is a Phoenix 282837-3 3x50.8mm connector. On this connector are mapped these instances: UART3 or UART8.
Signals[edit | edit source]
The following tables describe the interfaces signals:
J66[edit | edit source]
| Pin# | Pin name | Pin function | Pin Notes |
|---|---|---|---|
| 1 | EXT1_P1 | RS232_RX or CAN_P | optional RS232 or CAN port |
| 2 | EXT1_P2 | RS232_TX or CAN_M | optional RS232 or CAN port |
| 3 | EXT1_GND | GND | connected to DGND directly or to PCN GND ring via RC filter |
J67[edit | edit source]
| Pin# | Pin name | Pin function | Pin Notes |
|---|---|---|---|
| 1 | EXT2_P1 | RS232_RX or RS485_A | optional RS232 or RS485 port |
| 2 | EXT2_P2 | RS232_TX or RS485_B | optional RS232 or RS485 port |
| 3 | EXT2_GND | GND | connected to DGND directly or to PCN GND ring via RC filter |
Device mapping[edit | edit source]
RS232 is UART3 and it is mapped to /dev/ttymxc2 device in Linux
RS485 is UART8 and it is mapped to /dev/ttymxc7 device in Linux
CAN is FLEXCAN1 and it is mapped to can0 device in Linux
Device usage[edit | edit source]
The RS232, RS485 and CAN use the standard protocols.
