是的、我重新读取了 LINID。 我指向的 LIN 示例显示了如何写入 LINID 寄存器以及如何设置 RXIDMASK/TXIDMASK。
//
// LIN MASK Configuration 2
//
LinaRegs.LINMASK.bit.RXIDMASK = RXID_MASK; // 0xA
LinaRegs.LINMASK.bit.TXIDMASK = TXID_MASK; // 0xA
//
// Initialize the Slave LINIDNUM register
//
LinaRegs.LINID.bit.IDSLAVETASKBYTE = LINIDNUM_Slave; // 0x30
//
// Release SCI from software reset state - End of Config
//
LinaRegs.SCIGCR1.bit.SWnRST = 1;
//
// LIN Response Length
//
LinaRegs.SCIFORMAT.bit.LENGTH = RESP_LENGTH;
for(i=0;i<8;i++)
{
//
// Transmit Data - This populates the LIN transmit
// buffers - no data is actually sent yet.
//
LinaRegs.LINTD0.all = *Tx_DataPtr++;
LinaRegs.LINTD1.all = *Tx_DataPtr++;
//
// Send ID by writing to LINIDNUM register
// This causes the ID to be written to the bus. In turn,
// this causes both TX and RX ID matches in the slave task
// to occur - causing the data in the transmit buffers to
// be placed on the bus and also read into the receive buffers
//
LinaRegs.LINID.bit.IDBYTE = LIN_ID; // 0x3A
