@greg7282 Жыл бұрын
From Datasheet: The USB and CAN share a dedicated 512-byte SRAM memory for data transmission and reception, and so they cannot be used concurrently (the shared SRAM is accessed through CAN and USB exclusively). The USB and CAN can be used in the same application but not at the same time.
@andrewpelletier1199 Жыл бұрын
My understanding is that a complete Canbus interface requires a CAN(micro) controller and a TRANSCEIVER. Your reference stm32-x has only the controller. You still need the TRANSCEIVER which gives you the actual CAN bus electrical signals that match an actual CAN bus in the car which you connect to. 😊 So the advantage of a module like the 2515 is is has BOTH CAN controller and the transceiver together in one unit which gives you the advantage of wiring with any dev board which does NOT have a controller

Hi! Great Video as always. Just wondering, could it work on a VW Polo 9n? (pre-restyling) The fact is, apparently it does not have CAN bus out of the OBD2 port, but instead it relies on a CAN Gateway (?) correct me if I'm wrong, but it should have CAN bus implemented inside, but just not available directly to the OBD2 port. In that case, could it be possible to tap into the CAN bus line from the CAN Gateway? thanks a lot.
@radekoplustil675025 күн бұрын
By looking at the schematics the pre-FL 9N Polo doesn't have a CAN gateway as it is integrated into the onboard supply control unit (BCM - body control module / BSG - bordnetzsteuergerät). It's a black box with many connectors located under dash on the left side. CAN-BUS from OBD port is connected to two pins on the BCM. Then there are two more pairs of CAN-BUS lines - 500kbps drivetrain CAN and 100kbps convenience CAN. Drivetrain CAN is on pins 3 and 5 of 16-pin black connector and convenience CAN is on pins 9 and 12 of 18-pin black connector.

So you used a different transceiver chip? And how did you set standby mode on the mcp2515; using a gpio on the arduino?
@atc14413 жыл бұрын
Via spi, and the mcp2515 has a gpio controlable via spi as well
@1malditoPerro3 жыл бұрын
@@atc1441 so in standby mode the 2515 only listens, transmitter function is turned off thus the power saving feature. Now my question is, if the transceiver is also asleep due to the the rxbuffer pin set high, how would the vehicle can bus on it's own wake up the 2515 if it needs to do so via the transceiver? I'm stumped 😕

Hallo, wie geht's dir? Ich habe einen Polo 9N (aus Brasilien), fast der gleiche wie deiner, aber er hat das Display auf dem Panel. Ich würde gerne wissen, ob es eine Möglichkeit gibt, es mit meinem Android-Multimedia zu verbinden, da das alte Radio RD keine CAN + UND CAN-Anschlüsse hatte. Es verfügt über RCH-, CTRL-, LCH-, +8-, SWC-, CLK-, DATA- und ENA-Anschlüsse

Hi Aaron, this is a great video. I found it very interesting and thought of listening my Suzuki car . So far I am able to recognise some IDs connecting to obd2. I am able to send the can message to car but with a limited effect. I can send turn indicator messages and it only flashs turn indicator on dashboard but not the actual indicator. Same with the headlight message it glow the dashboard but headlight is not turned on. Can you please guide me.
@atc14414 жыл бұрын
Hi. On every car it is different and in cars are multible busses so its possible that either the headlight controll is on another bus or it is not possible to switch the light with that command and you only see the dashboard status messages. My suggestion would be to try it on other busses, but all on your own risk :)
@navdeepsidhu71784 жыл бұрын
Hi, Thanks for your prompt response. I assume that IDs are correct as with ignition off there are very few IDs active. And headlight, turn indicators and emergency flasher are respoing the same way. One more thing i ran OBD PIDs connecting can bus h and L and got the correct readings (rpm, temp etc). K- Line also present at pin 7 of OBD2. As suggested wher can I find other can bus? It is also worth mentioning that steering wheel controls and infotainment system is not on can bus. Thanks

One bus should be the Motor bus. There you have more controll over the car

Hi, I really like what you have done here. I am trying to use the software CanHacker you have mentioned but I cannot get any data to appear on it. I can initialize a connection successfully. By using some of the example libraries for the MCP2515 I can get can bus data to appear in a serial monitor but it is very hard to analyse this due to the speed at which the data appears on screen, hence trying to setup the CanHacker software you are using. My setup is the same as yours, I am using an Arduino nano and the same MCP2515 board. I am wondering if i have the can adapter code configured incorrectly. Very much enjoying your videos if you have any suggestions I would appreciate it very much! Shane.
