You need to write receiving and sending messages to the LIN bus on the STM32

It is necessary to constantly send a message to the LIN bus with ID B4, without bytes, also ID 78 with 8 bytes, all 0x00. If in ID B4 the second byte is 23, then you need to make 2 byte 0A in ID 78, if again 23 in ID B4, then 2 bytes 0B in ID 78, 0B, if again 23 in ID B4, then 2 bytes 09 in ID 78. Transiver TJA1020
