Hello FBern.2,

Your question doesn't seem very clear to me, but if you are asking about MCU/MPU Filters panel, it is possible to check more than four criteria.

I'm sorry....My mistake.

I am doing a project in STMCube. In this project I am using a CAN chip fo communication.

In the libraty to manage (HAL FDCAN) can communication I can't add more than two filters for received address

Hello FBern.2,

Sorry for the delay. The problem isn't reproduced on my side, it is possible to add more than two acceptance filters.

Please refer to https://www.st.com/resource/en/application_note/dm00625700-fdcan-peripheral-on-stm32-devices-stmicroelectronics.pdf , as well as https://www.st.com/resource/en/reference_manual/dm00314099-stm32h742-stm32h743-753-and-stm32h750-value-line-advanced-arm-based-32-bit-mcus-stmicroelectronics.pdf for further information about FDCAN peripheral.

You can find multiple FDCAN examples (using STM32CubeMx Example Selector window) that may help you.
