DP256: Problem with receiving - rithes ameen - May 7 7:03:00 2005
Hi there ,
I am having a problem regarding reception of the data .
Identifier used is 00 for the controller Mc9s12dp256
I have set my Acceptance register to
CAN0IAR[0-7]=00;
CAN0IMR[0-7]=0x0FF;
and CAN0IAC=0x20; // That is 16 bit wide register
The controller is getting Synchroised that is "synch" bit is one.
But the Problem is that it is Show error by Setting CSCIF bit and RSTATE=1 ,RSTATE0=0;
I am not getting the Receive interrupt neither the flag is been set
Please tell me what might be the problem is it that bus time is not matching or anything else. Another request is that what is the declarative format of Interrupt service routine, i have tried out two ways that is
void interrupt 37 funname()
{
}
and
interrupt 37 void funname()
{
}
Can anybody please help me

Re: DP256: Problem with receiving - dwarkanath avarur - May 9 11:02:00 2005
Hello
1. Are you getting Receive frame bit set in the
control register ?
2. Is transmission happening. If transmission happens
then all your baud rate setting are all fine. if not
check for the transceiver setting.
Which is your transceiver and what is your baud rate.
Let me know, i will probe further
Thanks

RE: DP256: Problem with receiving - venki - May 9 11:42:00 2005
Hi dwarak,
Iam able to transmit a Message with 100kbps.But iam finding that
CANSTATUS CHANGE bit is setting then it is
showing TXWARN error.what could be the REASON.From other working CAN node
iam not getting the ACK.
some times while transmitting,iam getting the RXWARN error why i dont
know,but iam not getting TXWARN error at that time.
For the both sides the BAUD rate is 100kbps only.
In loop back iam not getting the bytes whatever i transmitted, into the
Reception registers.
thanks a lot,
i strucked at this problem.Your help would be appreciated.

Re: DP256: Problem with receiving - rithes ameen - May 10 23:54:00 2005
hi dwarkanath,
I checked out in the LOOPBACK mode and it is Setting the RXF flag register. The buadrate i have set is 500kpbs the trancevier MC33388. The thing is that the transmitting waveform doesnot show switch of state between 0 and 5V it shows Charging of a capacitor waveform shape for 0 to high transition i am suspecting the other end which a ATMEL board Haveing the Transciever AT6660.
Any thanks for replying i possible tell me where i am going wrong

RE: DP256: Problem with receiving - venki - May 11 0:16:00 2005
Hi Rithesh,
The transceiver MC33388 supports only baud rate from 10kbps to 125
kbps.In transceiver WAKE pin should not be left open.
we shorted that pin to ground.Keep the baud rate same at both ends.when we
transmit the message from the other CAN node we are
getting the error frames only.
you see once transceiver MC33388 pdf document.
while transmitting from the DP256 CAN node we are getting the TX ERROR i.e
error passive state.
Have u observed it.
venki.

Re: DP256: Problem with receiving - prashanthu baragur - May 11 1:14:00 2005
Hi
The CAN transceiver MC33388 supports "Baud rate from 10 kBaud up to
125kBauds" only.
Hope this helps you.

[OT] 120VAC to 5V regulation. - John Dammeyer - May 14 23:56:00 2005
Hi guys,
A while ago I read about some new voltage regulator devices that could take the rectified/filtered AC line voltage input and provide
a low DC output using 100Khz or higher switching regulator technology. Essentially a buck regulator with either a simple inductor
or a transformer. Isolation is not a big issue here although always nice.
I've tried googling on various subject lines but can't find any. I believe that technology is now being used in many of the wall
wart supplies. Suggestions?
Thanks

Re: [OT] 120VAC to 5V regulation. - joncas04 - May 15 8:59:00 2005
Hello John
the Fairchild "green" SMPS ICs work very well, for example:
http://www.fairchildsemi.com/pf/FS/FSDM0565RB.html
The datasheet has complete schematics and very little external
circuitry is required.
(makes a great power supply for HCS12 circuits, too, so it's not
totally OT!) --- In 68HC12@68HC..., John Dammeyer <johnd@a...> wrote:
