CAN Extended Frame 29-Bit

[Lynda96]

Hi
I am working on CAN bus with NUCLEO BOARDH743ZI2 ,so I am coding with mbed studio 1.4.3 , I am just doing a loop test (send data from CAN1TD and receive it from CAN2RD with the same board ) this is the code that I have tested

it doesn't work with EXtended format ,it works only with Standard format
Can you please ,tell me where is the problem ?
Thank you

Hi
Maybe CAN expert community have some tips: @mynameismichael @pmancele @veppikeppi

I have never tried this direct wiring, only with transceivers to get CAN but in my code i also set
messageOut.type = CANData;

HI
Thank you for your answer .
Actualy , I modified a value on the library can_api.c

obj->CanHandle.Init.ExtFiltersNbr = 64; it was equal to 128 I changed it to 64 and it works

Hi @Lynda96

Thx

Hi @jeromecoutant
I don't understand what do you mean ?

[jeromecoutant]

obj->CanHandle.Init.ExtFiltersNbr was equal to 128 I changed it to 64 and it works

Do you think you can propose a clean patch that is working for every one ?

[Lynda96]

it works for me but i don't know if it's gonna work for you ,i change it cause on datasheet Can EXTENDED Filter is 64 elements ,so i think it's depends to the board you are working on .
I am working on NucleoBoard h743zi2

@Lynda96 did not fill all necessary information for full context, especially what MbedOS version was used.

This issue is know issue and it was already solved in MbedOS 6.14 #15000
This one can be closed. What do you think @0xc0170 @jeromecoutant ?
