Hello

I am a beginer in zigbee network.

I want use uart in generic_app in z-stack 3.0. I config uart in function zclGenericApp_Init :

halUARTCfg_t uartConfig;
uartConfig.configured = TRUE;
uartConfig.baudRate = HAL_UART_BR_115200;
uartConfig.flowControl = TRUE;
uartConfig.flowControlThreshold = 48;
uartConfig.rx.maxBufSize = 128;
uartConfig.tx.maxBufSize = 128;
uartConfig.idleTimeout = 6;
uartConfig.intEnable = TRUE;
uartConfig.callBackFunc = NULL;
HalUARTOpen (HAL_UART_PORT_0, &uartConfig)

after I put

uint8* mes= " UART0 Message ";

if ( keys & HAL_KEY_SW_1 )
{

HalUARTWrite (HAL_UART_PORT_0,mes,sizeof(mes));
}

zclGenericApp_HandleKeys function.

in IAR preprocessor , i define

HAL_UART=TRUE
ISR_KEYINTERRUPT
HAL_UART_DMA=1

But when i press key 1, no message trans over uart port.

Can you tell me where is problem ?

Thanks

Try to set a breakpoint on "HalUARTWrite (HAL_UART_PORT_0,mes,sizeof(mes));" and see if it hits when you press key 1.

No. it not hits. It stopped in HalDmaInit() function

0 YiKai Chen over 7 years ago in reply to quang nguyen76

Guru 735685 points

If it doesn't hit, I think you don't make your key 1 work properly. You should fix it first.

0 quang nguyen76 over 7 years ago in reply to YiKai Chen

Expert 1370 points

yes. i found it. it is HAL_KEY_SW_6.
Thanks you

Guru 735685 points

Does it work now?

0 quang nguyen76 over 7 years ago in reply to YiKai Chen

Expert 1370 points

Sorry. I will not work. but when i put a set led command in zclGenericApp_HandleKeys function, it work well.
So i think error from to uart config or define preprocess. But i not found it .

What is the return value of HalUARTWrite when you call HalUARTWrite ?

0 quang nguyen76 over 7 years ago in reply to YiKai Chen

Expert 1370 points

Sorry for my delay.

It return 0 for HalUartWrite function.

What the problem ?

0 YiKai Chen over 7 years ago in reply to quang nguyen76

Guru 735685 points

Try to replace “sizeof(mes)” with 8 to see if it works.

Please check the HAL Driver API and the following E2E threads:

when i set a breakpoint in line :

HalUARTOpen(HAL_UART_PORT_0,&uartConfig);

It give me an error

Mon Apr 02, 2018 17:21:51: Failed to set breakpoint: Driver error.

What is problem ?

0 YiKai Chen over 7 years ago in reply to quang nguyen76

Guru 735685 points

Do you try to replace “sizeof(mes)” with 8 to see if it works?

0 quang nguyen76 over 7 years ago in reply to quang nguyen76

and HalUARTWrite () return value 2, U0DBUF is ' \0' when i debug.

0 YiKai Chen over 7 years ago

Guru 735685 points

If you use “HalUARTWrite (HAL_UART_PORT_0,”Hello world”, 10);” instead of “HalUARTWrite (HAL_UART_PORT_0,mes,sizeof(mes));”, can you see “Hello World “ output on UART?

0 quang nguyen76 over 7 years ago in reply to YiKai Chen

Expert 1370 points

no. I replace it but i don't see any thing

0 YiKai Chen over 7 years ago in reply to quang nguyen76

What is the return value of HalUARTWrite now?

0 quang nguyen76 over 7 years ago in reply to YiKai Chen

Expert 1370 points

now it return 10

Can you use scope to check if there’s signal on UART TX pin?

0 quang nguyen76 over 7 years ago in reply to YiKai Chen

Expert 1370 points

Sorry. I don't have scope now

0 YiKai Chen over 7 years ago in reply to quang nguyen76

Guru 735685 points

It seems your UART works fine. I suggest you to find a scope to check TX signal first.

Thanks you for support.

Are you using the CC2530EM or your own customer board? The CC2530EM uses P0.2 for RX and P0.3 for TX, you should check your hal_uart files to make sure you are doing the same. The ZNP projects will also help provide UART communication examples.

In my board, P02 for RX and P03 for TX.
In _hal_uart_dma.c I see
HalUARTInitDMA(void)
{...
#if (HAL_UART_DMA == 1)
PERCFG &= ~HAL_UART_PERCFG_BIT; // Set UART0 I/O to Alt. 1 location on P0.
#else
PERCFG |= HAL_UART_PERCFG_BIT; // Set UART1 I/O to Alt. 2 location on P1.
#endif
PxSEL |= HAL_UART_Px_RX_TX; // Enable Tx and Rx on P1.
.....
}
Why Enable Tx and Rx on P1 ?

Guru 735685 points

There’s no specific reason for this. You can change it according to your application.

When I config HalUARTOpen (HAL_UART_PORT_0, &uartConfig), how i identify it is uart0 or uart1 work.

When i try working with HAL_UART_PORT_1 with define ZTOOL_P2, data transmit over P1.6 and P1.7. But when i change it to HAL_UART_PORT_0 and try change data pin, it will not work.

0 YiKai Chen over 7 years ago in reply to quang nguyen76

Guru 735685 points

If you want to use HAL_UART_PORT_0, you should use ZTOOL_P1.

0 quang nguyen76 over 7 years ago in reply to YiKai Chen

Expert 1370 points

yes. But in port 0, P0.2 and P0.3 for UART0 ; P0.4 and P0.5 for UART1. How i identify it ?

0 YiKai Chen over 7 years ago in reply to quang nguyen76

Guru 735685 points

If you intend to change between UART alt.1 and alt.2, you can manipulate PERCFG which you can refer to CC2530 user guide at www.ti.com/.../swru191f.pdf

0 quang nguyen76 over 7 years ago in reply to YiKai Chen

Expert 1370 points

yes. I understand it.
Thanks you
