PEAK-System Forum

Dear Marvin,

following your suggestions I could again Programm my PEak router. I guess it was a combinbation of some old libs which compiled fine but did not load. No all is fine

You can close my issue now.
Thank you! - always nice to get efficient help from Peak in an easy way.

I want to program the router (I did this last year, now I have a new notebook)

Start PCAN-Flash
Connect
(find PCAN-USB pro)
select Channel 1

Thanks again for the clear answer.
The attached 1_routing.zip has again the too small queue sizes (8 and 16 messages for TX and RX_Queue). Since I am using now 64 for both I am closer to the 56/100 message size for the PPCAN standard and therefore it should not be too large.
Once I wanted to ...

Thanks for your answers.
I followed your advice and could create the needed sleep-function.

However, the need to wait was wrong - it is very probable a problem of buffer overrun which I wanted to fix.
Problem solved

Thanks for the help delivered so far. Good news:

Update on buffer tests
At first a slow increase with some improvements. Then I increased all buffers to 64
#define CAN1_TX_QUEUE_SIZE 64
#define CAN1_RX_QUEUE_SIZE 64

#define CAN2_TX_QUEUE_SIZE 64
#define CAN2_RX_QUEUE_SIZE 64

#define CAN3_TX ...

thanks! Always a pleasure to find something new from PEAK.

I have changed can_user.c and no result. And removed the filter code from main.f

// init hardware
HW_Init();
//Filter setup see can_user.c
// init CAN
CAN_UserInit();
// Set green LEDs for CAN1 to CAN4
HW_SetLED ( HW_LED_CAN1 ...

Thanks, again for the clarification.
I would like to test the filtering for getting a better performance.
The following compiles bit the code does not filter the CAN-Message ids.
What am I doing wrong?
Is there a special sequence of other commands needed to activate filtering?



int main ...

CAN-Flashing is working again - seems to be that init needs to be called after the filter
All three filter commands do not seem to work. Maybe my idea of filter is wrong?
Filter on: I guess it will not let commands thru in channel 2. I hope they would also not fill the buffer.
But somehow - no ...

Sorry, new questions:
I try to filter to avoid the overrun:
//Filter setup
u32_t IdStart, IdEnd;
CANStatus_t FilterStat;
FilterStat = CAN_InitFilters ();
IdStart = 0x400;
IdEnd = 0x43e;
FilterStat = CAN_FilterAddId ( CAN_BUS2, FILTER_11BIT_ID, IdStart,IdEnd);
FilterStat= CAN_SetFilterMode ...

English again:
Thanks for the clear message!
More questions:
the 56 and 100 message queue - is it per device or per CAN-channel?
Where do I find the h-File for the SpecialIn addresses of the internal variables?

In CAN.h I see a filter mechanism - would that help to reduce the load for the ...
