uart in Z Stack GenericApp

You can check how UART is initializes and used in MT_UART.c .

HI YiKai Chen,

                         These files are also defined in hal_uart_isr.c so at which file I write the configuration code for UART in Z Stack.

You can copy the code in MT_UartInit to your own zclXXX_init.c, and make your own UART callback function like MT_UartProcessZAppData.

Hi YKC,

              I tried the all UART module and debug the code, the debugger goes into HalUARTWriteISR function.

but I doesn't print the data into hyper terminal.

My Code:

In GenericApp.c

halUARTCfg_t uartConfig;
/* Initialize APP ID */
  //App_TaskID = 0;
  /* UART Configuration */
 unsigned char str[]="Hello everybody";

 uartConfig.configured = TRUE; // 2x30 don't care - see uart driver.
 uartConfig.baudRate = HAL_UART_BR_115200;
 uartConfig.flowControl = TRUE;
 uartConfig.flowControlThreshold = 48; // 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 = NULL;
 HalUARTOpen (HAL_UART_PORT_0, &uartConfig);
 HalUARTWrite(HAL_UART_PORT_0, str, 15);

and control goes into HalUARTWriteISR  function in _hal_uart_isr.c.

My Q:

1.I can't get the data into Hyper Terminal so what are the thinks I need to do?

Check your HW to make sure TX/RX pins are correct.

Hi YKC,

              I am using UART0 so as u said I am using P0.2-RX and P0.3-TX in my board and I am using baudrate in hyper terminal what I used in my program HAL_UART_BR_115200.

1.Can u give any idea where I did the mistake ?

2.What are the details need my from side?

Do you enable flow control on your hyper terminal? You code looks without problem. If it is possible, I would suggest you using scope to check if there is any signal on your TX when you use uart write.

Hi YiKai Chen,

                          I am using check with scope but I can't get any data in my scope.

Give any suggestion where I did the mistake?
