7223	Hi Allen Thanks for your reply but I am bit confused about formula. In the manual the formula mentioned; TSeg1 = (TSEG1 + 1)tq TSeg2 = (TSEG2 + 1)tq Where...	Manivannan manivannan.d@...	Jul 3, 2009 9:58 am

7225	Such a simple math error. Alan's formula is: Baudrate = fCAN / ((BRP + 1) * (1 + TSeg1 + TSeg2)) and clearly TSeg1 and TSeg2 are integers as is the number '1'...	John Dammeyer johnd@...	Jul 6, 2009 4:20 pm
7226	Good news from TI. They just released a 4K V isolated CAN transceiver. Both 8 pin and 16 pin packages are available. Price info is not published yet. The 8-pin...	Funny NYPD funnynypd@...	Jul 13, 2009 6:52 pm
7227	Hi Funny, Yes, this is a good product that I got into the works before I left TI. Good to hear that they finally got it out the door. Cheers, Steve C. From:...	Steve Corrigan steve.corrigan@...	Jul 13, 2009 8:08 pm

7230	Hi Funny, I looked at the first datasheet that I wrote for the ISO1050 and it was in November 2006. This should give you an idea of the multiple problems ...	Steve Corrigan steve.corrigan@...	Jul 14, 2009 5:07 am

7241	Igor, I've used both internal and external (SPI) CAN controllers; externally, you can't tell the difference. External controllers are intrinsically slower to...	Allen Pothoof apothoof@...	Aug 2, 2009 4:46 pm

7244	Hi Rick, Thank you for your answer. It makes sense...Maybe I have to think about changing to AT90CAN128 controller. Olimex has a good solution with this chip...	IGOR igorreal@...	Aug 2, 2009 10:27 pm
7245	Hi, I've had a bit of experience with trying to send messages quickly on the CAN bus. I would take a different approach from yours. First I'd determine what...	John Dammeyer johnd@...	Aug 3, 2009 3:06 am
7246	The MCU with CAN module is absolutely recommended. The standalone CAN module with SPI bus, the device itself is not an issue, the chanllenge is how you get...	Funny NYPD funnynypd@...	Aug 3, 2009 4:00 pm
7247	Rick, I agree with you, I prefer internal CAN controllers. It is typically a quicker set-up and has less overhead (sometimes much less, as you pointed out)....	Allen Pothoof apothoof@...	Aug 3, 2009 4:36 pm
