Hi~

I'm using S32G274A.

I know that LLCE CAN RX FIFO has HW Filter value

and it can be set by these configuration below.

How can I set filter value using Filter code and filter mask?

Could you give me more details about 'filter value calculation'?

Refer to Sections 4.123. through 4.125 of S32G CAN_LLCE Driver User Manual
for the description of these objects. The actual values depend on the message
types you application needs to receive and the way it wants to handle them.
There are no applicable calculation formulas. Study the description of Rx filter
and related calls in Sections 1.3.2.4 and 3.1.2.10 of LLCE Firmware User Guide
to understand the meaning of these fields.

The documents mentioned above can be found:

S32G CAN_LLCE Driver User Manual - under plugins\eclipse\plugins\Can_43_LLCE_TS_T40D11M10I2R0\doc\

LLCE Firmware User Guide - under firmware\llce_interface\doc\

all paths are from S32G LLCE Gateway installation directory.

Best Regards,
Platon
