Supported Protocols

PduApi is under development and more protocols are in preparation.

Overview of protocols

Protocol short name	Description
ISO_11898_RAW	Raw CAN
ISO_15765_3_on_ISO_15765_2	Uds on CAN
ISO_14229_3_on_ISO_15765_2	Uds on CAN
ISO_14229_5_on_ISO_13400_2	Uds on DoIP

Raw CAN

ISO_11898_RAW is the protocol name for CAN-BUS

The supported D-PDU API Shortnames for protocol ISO_11898_RAW can be realized with following hardware:

Protocol/Shortname	Description
ISO_11898_RAW	ISO RAW CAN running on CAN-Bus ( CAN, CANFD depending on your hardware and ComParam CP_CANFDTxMaxDataLength >= 8 )
ISO_11898_RAW	ISO RAW CAN running on CanEth

Uds on CAN

The supported D-PDU API Shortnames for protocol Uds on CAN can be realized with following hardware:

Protocol/Shortname	Description
ISO_15765_3_on_ISO_15765_2	ISO UDS on CAN
ISO_14229_3_on_ISO_15765_2	ISO UDS on CAN
ISO_15765_3_on_ISO_15765_2	ISO UDS on CanEth
ISO_14229_3_on_ISO_15765_2	ISO UDS on CanEth

Uds on DoIP

Protocol description for ISO_14229_5_on_ISO_13400_2 is 'ISO UDS on DoIP'.

Protocol/Shortname	Description
ISO_14229_5_on_ISO_13400_2	ISO UDS on DoIP
ISO_14229_5_on_ISO_13400_2	ISO UDS on DoIP (connected to pduapi_ota_switch )*

* PduApi has a Module which an connect the doip_ota_switch directly.
This implements an transparent OTA functionality without any adaptions.
It has the advantage that no UDP package could be lost during the initialisation phase.

CanEth

CanEth is a bustype which can be used in combination with CAN protocols. The hardware is a Can-Eth-Gateway. To use a CAN protocol within PduApi select the BusType IEEE_802_3_ID (Ethernet) from DoIP in PDUCreateComLogicalLink or PDUGetResourceIds.

On the market multiple Can-Ethernet Gateways exist. PduApi supports the following CAN-Ethernet Gateways protocols:

• CAN/Ethernet gateway by proconX. The protocol is made public in a wireshark dissector. It is an UDP protocol running on port 11898. The protocol is specified and documentation can be found at www.proconx.com->canframe.pdf
• Another option for a CAN-Ethernet gateway is a software implementation by PduApi running on Raspberry PI: can_eth_gw. PduApi uses the same protocol as CAN/Ethernet gateway by proconX because it is well designed and supported by a wireshark dissector.

Planed protocol support:
