I have a beginner's question about CAN and level shifting and hope this is the proper place.
Using TJA1049 I am trying to talk to a device with CAN bus.
In the attached image yellow and red are the outputs of TJA1049 CANL and CANH.
Split pin of the part is attached to ground using a...
Please consider CAN communication network in a heavy vehicle:
Steering Electronic Control Unit (ECU) has CAN 2.0B. It doesn't have J1939 stack.
All other ECUs in this network are implemented with J1939 stack.
Can CAN 2.0B coexist with J1939?
What code changes are needed in steering ECU and...
Consider an Electronic Control Unit (ECU) mounted in a vehicle. Let's say this ECU has Three CAN channels as follows:
Do these Three CAN channels have to be on different CAN networks? Another words, for example, CAN 1 and CAN 2 are never on the same CAN network?
I want to start a small project for the purpose of ensuring communication between an arduino card and the ECU of my car through the CAN bus.
- My care model is : RENAULT SYMBOL
- Micro-controller : ATMEGA328P-PU (ARDUINO UNO).
- MCP2515 Card...
My project diagram is similar to this idea,
Lets say input is 3p 380VAC, 60Hz, Main Transformer MTR runs at 20kHz, DC output should be 50-147 v, charging current 100A. Should have CC and CV mode of operation.
I need to implement FW with following facilities,
1. Shunt/ Temperature...
I don't know why but I'm having a tough time decoding CAN Bus data frames, even after looking at many sources showing bit field diagrams of how the data is supposed to be structured.
Background on project/goal
My main goal is to connect directly to an electronic turbo actuator...
