Does the CanController require the SPI Mikroe Can bus device?

Endpoint

Regarding the tutorial:
https://docs.ghielectronics.com/endpoint/tutorials/can.html

Does the Controller work with the MIKROE-986?

2

No, CAN on Endpoint is built-in and there is no option for SPI.

3

How does one connect CAN hardware to Endpoint Domino then? (to get the differential signaling stuff)

4

Sorry because was not clear about this, built-in mean software, not hardware.

On Domino there is no CAN hardware added, you may need this:

5

Which pins do those attach to?

6

Looking at other GHI SBCs I see that the CAN signals are attached to pins that can be configured as UARTs.

7

Is that true for the Fez Flea as well?

8

I am confused. Why Fez Flea here ? :))

Anyway, endpoint, on the back you will see CAN 2 on PB12, PB13.

9

So that’s what CRX and CTX are? Can RX and Can TX?

Yes, CRX is CANRX en CTX is CANTX.

You should connect CANRX from Domino to CANRX of a CAN transceiver, CANTX should be connected to CANTX as well. In CAN it’s not standard to connect TX to RX like with UART/Serial.

We favor isolated transceivers like ISO1050 or ISOW1044 because we operate in industrial environments with different power domains.

A more common transceiver that is not isolated is the SN65HVD230

When testing, don’t forget the impedance resistors :wink:

Yes, or you can use PD0 (RX), PD1 (TX) as CAN1, right after GND, 3.3V on X5 header.
