How about configure bits?

Thanks!
It helps!

This variant sends only one message

Code: Select all

36,010 6C1      8 01 01 00 03 00 00 00 00 ASCII:

And it always compile hex with mistake in configuration chip. It sets bits 5 and 7 in address 30000 as 1. But they can't be set as 1.

I'm confused.
How does it work?

I have solved the problem.
18f25K80.h doesn't have these bits in cancon register unlike 18f2580.h
So I can write cancon = 0x20
or add to 18f25k80 bits intto cancon_ro7

Barmaley_GMN

I've rebuilt scheme with 15f25K80 and will check

I need help!

I have to change macro CheckTX1 to

Code: Select all

FCR_RETVAL = FC_CAN_SPI_CAN_Status_2(160);
switch (FCL_BUFFER)
{
   case 0: FCR_RETVAL = FCR_RETVAL;
  }

?

Barmaley_GMN

How can I check if TXB0CTRL.TXREQ MCP2551 is 0?

Barmaley_GMN

It seems like external channel doesn't set TX_Data and just sends buffer. When I connect both CAN channel I see that 43,562 001 8 01 01 02 03 04 05 06 07 ASCII: 43,563 001 8 01 01 01 03 04 05 06 07 ASCII: 43,564 001 8 02 01 02 03 04 05 06 07 ASCII: 43,566 001 8 01 01 01 03 04 05 06 07 ASCII: 43,567 ...

Of course! It connected to CAN-hacker. Listing without delay and checks.

I have the same problem. This code sends message with the same data 6c1 8 9C 00 00 00 00 00 00 6c1 8 9C 00 00 00 00 00 00 6c1 8 9C 00 00 00 00 00 00 6c1 8 9C 00 00 00 00 00 00 (zero byte can change after restart ) It seems Lo doesn't change. But if I insert delay for 5 ms it works fine. But delay is...

Barmaley_GMN

The problem seems to be solved. I have achieved my main goal. It sends all the frames without external delays with check from your macro. And the program does it with the same timings. It's a little bit strange, but internal CAN (I suppose) has a check from box but external CAN. And THANK YOU VERY M...

Barmaley_GMN

As I see I can't use ext.CAN and SPI together or I have to run init. for every component before every operation? p.s. If I use SPI (FCD_06c41_SPI_Master1__SendChar(129);) I see almost 2 times more frames (546 from 3000). Now I have checked some variants (spi, can2,can1) All of them have the same tim...

Hi!
Sure!

THE FC5 works the same.9 loses from 10.
Can I check if the frame is sent and wait for it?

Barmaley_GMN

There was my mistake about strange sending singular frames from CAN1. I didn't use additional pause for relay (it disconnects CAN1 and CAN2). And time to disconnect was enough for 1 frame.
Sorry.
But losses exists as described.

Barmaley_GMN

I removed the old CAN.fcpx and placed your to component directory.
Make new hex and... don't see any positive changes:
It steel sends 1 jf 10 frames and 1 from unused component (CAN1)

And one more strange moment: If I use 3buffers at the same time variant I see singular sending on internal CAN1 channel with data from the flowchat for CAN2. And if there is variant for 3 buffers (with my C) I see singular sending on internal CAN1 channel with data from his buffer TX2 But there is n...

Barmaley_GMN

If I add send for 3 buffers;

Code: Select all

#define FCV_0e702_can2__CAN_RTS_TXB3 (135)

after CAN2 init
and

Code: Select all

FC_CAN_SPI_CAN_Command_2(FCV_0e702_can2__CAN_RTS_TXB3);

instead of CAN2 sendBuffer macro
I see

If I disable macro SetTxData I see

Next with one TX buffer (1-1-1) Ext_Can2(1-1-1).jpg Next one like previous but added faster SPI (x4) Ext_Can2(1-1-1)+faster_SPIx4.jpg If I add 2us delays after every CAN macros - it doesn't matter the result on the screen is the same. I made some tests for every variant I have seen different periods...
