TI 工程師您好 詢問z-stack 使用RS-485 問題

Other Parts Discussed in Thread: Z-STACK, CC2530

您好

   z-stack 預設使用DMA 方式，baudRate 2400~115200

  但我周邊裝置是

  baudRate =   1200 

    EVEN

    8 bit

   stop bit   =  1

  我修改_hal_uart_dma.c

  增加了

 case HAL_UART_BR_1200:
      UxGCR = 5;
      dmaCfg.txTick = 274;
      UxUCR = UCR_STOP | UCR_PARITY | UCR_D9 | UCR_BIT9;
      break;

UART 結構參數

   halUARTCfg_t uartConfig;
       uartConfig.configured           = TRUE;              // 2x30 don't care - see uart driver.
       uartConfig.baudRate             = SERIAL_APP_BAUD;
       uartConfig.flowControl          = FALSE;
       uartConfig.flowControlThreshold = 64; // 2x30 don't care - see uart driver.
       uartConfig.rx.maxBufSize        = 128;  // 2x30 don't care - see uart driver.
       uartConfig.tx.maxBufSize        = 128;  // 2x30 don't care - see uart driver.
       uartConfig.idleTimeout          = 6;   // 2x30 don't care - see uart driver.
       uartConfig.intEnable            = TRUE;              // 2x30 don't care - see uart driver.
       uartConfig.callBackFunc         =  BZ530_SerialApp_CallBack;

   都只能收 到前面 幾個字元  

   請問是否哪邊我沒注意到呢?

   謝謝~~
