WebThe provided address information consisted of CAN ID 0x6000001 and 0xC28001 which both boil down to 11 bit CAN IDs 0x001 in sending and receiving. Sanitize the SFF/EFF CAN ID values before performing the address checks. WebThe CAN controller’s interface consists of 4 signal lines known as TX, RX, BUS-OFF, and CLKOUT. These four signal lines can be routed through the GPIO Matrix to GPIOs. Signal lines of the CAN controller ¶.

Then let's say you want to remove some filters from this config + add new filters to it, then create a new rfilter_2 with that config, and do step 2: setsockopt (s, SOL_CAN_RAW, CAN_RAW ... WebID bits 28 - 21 (SFF: 10 - 3) ... This filter works as follows: A received CAN ID is AND'ed bitwise with can_mask and then compared to can_id. This also includes the CAN_EFF_FLAG and CAN_RTR_FLAG of CAN_xxx_FLAG. If this comparison is true, the message will be received by the socket.
