Strato Pi CAN setup
Jumpers
- For the CAN bus, we use the built in 120Ω terminal resistor, activated by bridging jumper JP3.
- For the RS-485, we use the built in bias network of resistors, activated by bridging jumpers JP1, JP2 and JP4. TODO, check this
Watchdog
The watchdog of the Strato Pi has to be configured for our use. First the firmware has to be updated to 3.5. Then we can connect to the serial interface.
| USBUART | Stratopi | Corresponding pin on RPI |
|---|---|---|
| GND | 6 | GND |
| 5V | 2 | 5V |
| RX | 35 | GPIO19 |
| TX | 33 | GPIO13 |
Where counting begins with the pin closest to the screw terminals as 1
