打開同星的TSMaster，推薦用32版本的，比64更穩定。同星的TSMaster的C小程序支持用戶嵌入代碼來控制CAN報文的收發邏輯。便于開發。

點擊設計里面的C小程序。

比如我現在想用小程序來實現繼電器0先開后關開1s關1s，然后繼電器1開1s關1s…如此往復到繼電器39
定義全局變量

if(flag)
{flag = 0;CAN_Data[0] = relay_ch;CAN_Data[1] = 0x0;       {// [1] CAN 0x240D BOB_BOX_SET_ONE_RELAY_STATE_REQ 控制單個繼電器TCAN f0 = {0,0x5,2,0,0x240D,0,{0}};memcpy(f0.FData, CAN_Data, 8);com.transmit_can_async(&f0);app.wait(0, "");}relay_ch++;if(relay_ch == 40)relay_ch = 0;}
else
{flag = 1;CAN_Data[0] = relay_ch;CAN_Data[1] = 0x1; {// [1] CAN 0x240D BOB_BOX_SET_ONE_RELAY_STATE_REQ 控制單個繼電器TCAN f0 = {0,0x5,2,0,0x240D,0,{0}};memcpy(f0.FData, CAN_Data, 8);com.transmit_can_async(&f0);app.wait(0, "");}
}

可以直接報文轉化為C腳本

也可以根據幫助手冊手寫。
TCAN類型是什么？可以在TSMaster.h里面看到。
