CANBus Duo
  • 0
  • Hello everyone, I'm interested in making a CANBus Duo without a blutooth chip. I am good with a soldering iron but my embedded hardware and software knowledge is lacking. Is anyone else more knowledge interested in this also and able to modify the original CANBus triple hardware schematics and software to accomplish it? Also it would be great if a shield for the Arduino mini Leonardo could be developed.

    Edit:

    Hmm might be able to rig something using the above shield.

  • Hi, I'm really interested in that simplified (and much cheaper) thing. I'm also have some skills in electronics, but no expirience with Arduino and same controllers. Would be great if you share your progress!

  • So far I have order the following modules and are waiting for them to arrive <a href="http://www.aliexpress.com/item/For-Arduino-MCP2515-CAN-Bus-Module-TJA1050-Receiver-SPI-Module/32385765132.html?spm=2114.01020208.3.56.kqdTr3&ws_ab_test=searchweb201556_4_71_72_73_74_75,searchweb0_0,searchweb201560_9">MCP2515 CAN Bus Module</a> <a href="http://www.aliexpress.com/item/Leonardo-R3-Pro-Micro-ATmega32U4-Board-For-Arduino-Compatible-IDE-free-USB-cable/1893754883.html">Leonardo R3 Pro Micro ATmega32U4 Board</a>. I have little experience with Arduino as well, although it is great more people are showing intrest in a cheaper simplified board.

  • well, I've ordered this stuff, too) Is there any significant differences between Mini (from your 1st post) & Pro Leonardo (you've ordered) boards?

  • 0
  • Both use the ATmega32U4 so they should be similar.

  • received mentioned hw (two arduinos & two can modules) - all is working perfectly! As for now - made them talk to each other. Going to connect two can modules to one Pro Micro. Am I need a eeprom chip in the future?) Maybe to program it without reflashing the Arduino.. (as in original Triple schematic)

  • I just received my hardware today aswell, I won't have time to play with it until exams are over. Mastereworm have you gotten everything to work using the schematic above? Can you post pictures of your setup? I too was also wondering about the eeprom as some revisions of the Can Bus have it and some don't.

    Cool!!

    Are you using the CBT firmware?

    When I start getting the smaller runs I'll be able to offer the hardware without BT for less. I'm also working on a Two CAN Bus device with wifi that will be significantly less expensive, and even faster as well!

  • Hi Derek, I'm very interested in a less expensive, faster CBD with wifi! I'm interested in programming some specific applications that can reach a broader audience than the car hacking community.

  • Just wondering if anyone has made progress on this? Ideally I need a dual canbus device with digital and analog inputs at car voltage levels
