下面給大家介紹一下，如果用上位機（表端Host MCU）或者PC機來配置PLC表端模塊，進行注冊連接的過程。

當大家把Prime固件程序燒寫到F28069，并上電后，從UARTA和UARTB同時都會收到下面的命令，此命令為：Read Blob request：96 00 04 00 01 00 04 00

1）當不希望此命令重復(fù)出現(xiàn)時，需要發(fā)送如下命令：

96 c0 08 00 01 00 04 00 00 00 00 00

此時會收到另外一條CRC32命令：96 00 04 00 00 00 04 00

2）再次發(fā)送如下命令：

96 c0 08 00 00 00 04 00 00 00 00 00

此時，Read Blob request 將不再發(fā)送。

接著大家可以通過Get System Info來獲取當前燒寫固件的一些信息， 具體解釋如下：

DSP?? : Load System Config Reply 0C 00 06 00 94 E5 00 00 00 00 ·???????? Status: 00 00 (success) ?

當Load System Config配置完成后，需要通過Soft Reset命令來保存設(shè)置。

Soft Reset HOST? : Soft Reset Request 05 80 06 00 B9 2D 00 00 00 00 ·???????? Reset type: 00 00 ? DSP?? : Soft Reset Reply 05 00 06 00 E3 16 00 00 00 00 ·???????? Status: 00 00 (success) 當然，在Soft Reset之后，用戶可以通過Get System Info語句來查看設(shè)置是否成功。 接下來就是設(shè)置接收和發(fā)送的一些參數(shù)，例如發(fā)送功率，調(diào)制模式，是否加上FEC和ROBO模式等等，當然本身固件上是有默認設(shè)置的，因此下面這兩條命令，在沒有必要的情況下，可以不做設(shè)置。 Set Info (PHY TX parameter) ?

接下來，也是最重要的一句語句就是進行注冊，連接用的Attach語句。DSP在接到這句串口命令時，首先要進行Register的過程，然后進行Connection的過程，因此需要一定的等待時間才能收到Attach Confirm的回復(fù)。具體過程請參考下一節(jié)的Sniffer軟件的使用說明。

Attach Request HOST? : Attach Request 10 80 0C 00 90 65 CB 80 06 00 00 00 00 00 00 00 ·???????? Device ID Length: 06 00 ( 6 bytes) ·???????? Device ID: 00 00 00 00 00 00 ? Attach Confirm DSP ? : Attach Confirm 10 00 12 00 B6 7E 00 00 00 00 06 00 00 00 00 00 00 00 84 00 00 00?? ·???????? Status: 00 00 ·???????? Length:06 00 (6 bytes) ·???????? Device ID ( 6 bytes) 00 00 00 00 00 00 ·???????? Source Address: 84 00 ·???????? Base Address: 00 00 ? ?

當注冊和連接成功以后，就可以進行數(shù)據(jù)傳輸了。數(shù)據(jù)的傳輸一定是由DC端發(fā)起的。

數(shù)據(jù)傳輸所需要的語句為Data Transfer, 當Host 收到由DC來的命令時，回復(fù)如下：

00 80 10 00 ED F4 00 00 01 00 00 00 00 00 00 00 00 00 01 02

所發(fā)送給DC端PLC模塊的數(shù)據(jù)位01 02

以上是對需要配置的串口命令的整理和所見，如果大家希望查看關(guān)于具體串口命令的具體解釋，請參考附件中的文檔—TI_plcSUITE_host_msg.pdf
