I want to create a LIN bus gateway module to receive and transmit some data But I have a problem when Sending the data from stm32f103c8t6 mcu to MCP2004E transceiver with Built in USART ,I was transmit the header just 3 byte (0x00,0x55,0x47) The data that I was transmit were 0 and FF (The data were read by Arduino that connect with LIN transceiver and voltage out from transceiver around 12V using oscilloscope to detected)
