6842	My original post seemed to be thrashed pretty badly, let me revise: [quote] but really its almost as simple as Open, Close, Send, Receive [/quote] Revised: ...	stunbmun stunbmun@...	Dec 1, 2008 8:12 pm
6843	Hi Team, I am using twisted pair wires as can bus. Up to baud rate of 125Kbps the transmission and reception are working smoothly. If I am going to higher rate...	Joy.George@...	Dec 2, 2008 4:42 am
6844	Hi Team, I am using TMS320F2812 DSP processor and To implement CAN communication between two processors (TMS320F2812) I am using PCA820C250 transceiver and...	Kasunaidu.Vechalapu@...	Dec 2, 2008 5:58 am
6845	Hi, Could you tell us the length of your bus? It must be Changing the sample point to greater than 83% is required to get 30m distance. John Dammeyer ...	John Dammeyer johnd@...	Dec 2, 2008 7:00 am
6846	Hi, We are in the initial state of implementing CAN protocol. Presently we are using 2 meters length of twisted pair CAN bus between two nodes. And we are...	Kasunaidu.Vechalapu@...	Dec 2, 2008 7:38 am
6847	Are you able to capture a scope photograph of a bus message? Set your software to send a single short 0 data length message with an 11 bit ID. Set your...	John Dammeyer johnd@...	Dec 2, 2008 7:51 am
6848	... Very often this is the only problem. But of course, with 1Mbit/s also a correct connection of the transceiver th the media is importand. We had cases were...	Heinz-Juergen Oertel oe@...	Dec 2, 2008 11:17 am
6849	Hi, we also use TMS30F2812 DSP, we are using with BR 500kbps, but we have also used successfully with 1 Mbps. IMO you may check some things may be the cause of...	Osmar Yang oy@...	Dec 2, 2008 11:19 am
6850	Hi, We have grounded the "slope control" pin (pin 8, Rs). As per the data sheet grounding of pin 8 gives "high speed mode". Thanks&Regards, V.Kasunaidu Emerson...	Kasunaidu.Vechalapu@...	Dec 2, 2008 11:22 am
6851	Hi Osmar, - Our terminating impedance is 124 Ohm (two 62 Ohm split resistors are used; 2.2nF capacitance is used between midpoint of split resistor...	Kasunaidu.Vechalapu@...	Dec 2, 2008 12:13 pm
6852	Hi, you�re right, the clock is 15 MHz (I was thinking about our other nodes using PIC, which use an external oscillator with 16 MHz). The only difference I...	Osmar Yang oy@...	Dec 2, 2008 5:48 pm
6853	Hi, We are using Optocoupler (6N135) between CAN transceiver and TMS320F2812 DSP processor. Same setup is used in both the nodes. We are able to transmit upto...	Kasunaidu.Vechalapu@...	Dec 3, 2008 12:23 pm
6854	Hi, Go to ti.com and order free samples of the ISO7221M. This will solve that problem. Steve ________________________________ From:...	Corrigan, Steve s-corrigan1@...	Dec 3, 2008 4:48 pm
6855	Hi, The 0.6uS delay is your clue. Let's walk through the theory assuming 0 propagation time through the wire but with 50nS through the CAN controller logic...	John Dammeyer johnd@...	Dec 3, 2008 7:32 pm
6856	Hi there - I want to run a single cable with as few conductors as possible that carries CAN and power that will be subjected to all sorts of tortures. It needs...	Michael J. Noone mnoone@...	Dec 4, 2008 11:42 pm
6857	I did a similar thing once with an RS485-based bus for the fire industry. The "single cable" part is the problem here, though. In the fire industry, the...	Geoff Field geoff_field2003@...	Dec 5, 2008 11:36 pm
6858	Perhaps you ought to look at FlexRay if your need is so critical. Some (many?) CAN controlers are not able to work under all fault conditions as described in...	Robert Boys RBoys@...	Dec 7, 2008 7:23 am
