Filter in CAN

[mculover]

Hi Giovanni,

For filter message in CAN Driver, Chibi RTOS provide structure CANFilter to do that.

I know that cf_register1 and cf_register2 for CAN_FxR1 and CAN_FxR2 in each Filter Bank.

What are meaning of cf_register1 and cf_register2 in each mode ?.
How to use cf_register1 and cf_register2 in Identifier List Mode and Mask Mode ?.

Thanks for advance.

HI Mculover,

I am afraid that there is no way around studying the STM32 Reference Manual, the matter is a bit complicated. The driver provides no mechanism to easily configure the filters, the initialization is performed at register level.

One of the next developments will be a visual configuration tool for the HAL but until then you have to configure them manually.
