JonnyBoats 40 Posted March 21, 2014 Share Posted March 21, 2014 I just ordered a couple of these an am interested in using them with the EK-TM4C1294XL Connected LaunchPad. This combination seems ideal for a CAN bus to eithernet bridge. Do you have any thoughts on this or see any reason why this combination might have issues? Thanks.

bluehash 1,581 Posted March 21, 2014 Share Posted March 21, 2014 I'll let @@spirilis answer. It should be ok, as long as the ETH pins do not interfere with the CAN pins. Update us when you are done with the project. BTW, I shipped your order today. Thanks! Quote Link to post Share on other sites
spirilis 1,265 Posted March 21, 2014 Author Share Posted March 21, 2014 Yep keep in mind there will be some wire soldering required between the CAN_TX, CAN_RX pins and your choice of boosterpack pins which must correspond to CAN pins on your specific launchpad (and which boosterpack header you use, since the TM4C1294XL has 2 of them). Study the boosterpack pinout in detail. The MCP2515 IC and crystal will not be necessary so you can ignore those. Btw what will you be connecting to it?

FYI looks like only CAN0 is exposed to the boosterpack headers (CAN1 exists but not in the boosterpacks, however its pins are exposed in that long strip on the right side). JP4 & JP5 need to be oriented for CAN, and then the 2nd boosterpack header on the board has CAN0Rx (PA0) at boosterpack pin J1.5 and CAN0Tx (PA1) at boosterpack pin J1.6 Something like this: (well, I forgot to orient JP4/JP5 correctly in that picture, but you get the idea) Quote Link to post Share on other sites
dpharris 13 Posted April 30, 2014 Share Posted April 30, 2014 Just received one of the 'CAN Bus BoosterPack's -- will now have to apply it. Will keep you posted. Time to re-read this thread, in detail. David spirilis 1 Quote Link to post Share on other sites
KNG 0 Posted September 11, 2014 Share Posted September 11, 2014 Hi Spirilis Have you looked at the CAN example code by TI dk-tm4c123g Firmware package? What do you think of their code vs yours? http://processors.wiki.ti.com/index.php/CLP_CAN http://www.ti.com/tool/sw-dk-tm4c123g "the DK-TM4C123G software package contains CAN example programs that can be easily ported to all three LaunchPads that support CAN."

palacios1367 0 Posted March 25, 2015 Share Posted March 25, 2015 Will this booster back work with MSP430F5438 Series of uC's development boards, I am trying to implement CAN bus in my pcb but wanted to verify/test functionality and this seems like my best bet. Do you have any suggestions? Quote Link to post Share on other sites
yyrkoon 250 Posted August 27, 2015 Share Posted August 27, 2015 @@spirilis So, instead of hijacking the other recent thread I thought I'd better post here. Unless you tell me there is a better place to post. Not sure I need a boosterpack, but am interested in that Microchip CAN controller. I also have not read all these post here *yet* so . . . sorry if I mention something you've already posted about. Anyway, I did glance at your github, and yeah, definitely more complicated than socketCAN for sure. socketCAN you just treat the CAN controller, which you->( generic term ) did not write a driver for- As a Linux socket. Everything already nice and abstract. So my idea is to find a decent devboard, that does not cost a whole lot with ethernet on it. *Or* maybe use one of those AT command set wifi modules ( which I can not think of the chip name for - offhand), then some sort of uC for comms. I was thinking PIC, because I find many of Microchips uC's interesting, and have never worked with one yet. But it doesn't have to be a PIC. Anything with SPI and UART, that can keep up will probably work. So anyway, I might bug you in the future if thats alright In the meantime I will definitely examine your code in detail as time permits. Quote Link to post Share on other sites
dubnet 238 Posted August 27, 2015 Share Posted August 27, 2015 @@yyrkoon NXP has a couple of ARM M0 varients that implement CANOpen in firmware on the chip as well as the CAN transceiver on chip. I think part #'s are LPC11C22 and LPC11C24. Not sure if these would be helpful to you but figured I would toss them out there. yyrkoon 1 Quote Link to post Share on other sites
yyrkoon 250 Posted August 27, 2015 Share Posted August 27, 2015 @@dubnet Thanks, I did a quick search and found the expresso board for the LPC11C24. price isn't too bad @$18. I'm still up in the air what all I want on a board (SPI? UART? ethernet ? - I don't know yet ). Quote Link to post Share on other sites
