lin software on STM32F103 - Detecting stop bit errors

fehrlest · ‎2019-06-04

I develop an own LIN slave node software stack for the STM32F103RB. This stack has to pass all tests from the LIN Conformance Test (according to ISO 17987-6). This test is a customer requirement.

Actually the software and/or the hardware could not detect error in the stop bits. (See test case PT-CT 38).

Is there a solution to detect a stop bit error during receiving or transmitting a data byte?

I could not find such a flag in the reference manual (RM0008).

Is there an undocumented feature to solve this problem?

Hello @fehrlest ,

Please note that STM32 devices are general purpose MCUs not dedicated for automotive usage.
