CC2530 UART1 problem

Other Parts Discussed in Thread: CC2530, Z-STACK

Hi All. We use P1_6 as TX and P1_7 as RX in cc2530 custom board. I tried to debug UART funciton in the board. So I wrote such program to test it. I'm using cc2530F256 chip and my IAR version is 9.20.2. After I run the program, I got nothing in the TX pin. I don't know why.

#include "ioCC2530.h"
#include <string.h>

#define uchar unsigned char
#define uint unsigned int

#define led1 P0_0

void delayms(uint ms);
void ledInit();
void uartInit();
void uartSend(char *Data, int len);

uchar RXTXflag = 1;
char temp;
uchar datanumber = 0;
char Rxdata[12] = { '0','1','2','3','4','5','6','7','8','9' };

If you would use Z-Stack in the end, I would suggest you to use APIs in hal_uart.c and HAL_UART_PORT1.

0 frank li99 over 9 years ago in reply to YiKai Chen

Intellectual 640 points

Ok, I will try the z-stack with APIs. Should I add HAL_UART_PORT1 in the Option->C/C++ Complier->Preprocessor->Defined symbols?

0 YiKai Chen over 9 years ago in reply to frank li99

Guru 735685 points

I mean when you use API HalUARTOpen and HalUARTWrite, you use HAL_UART_PORT_1 as first parameter. For example,

unsigned char str[]="Hello everybody";
halUARTCfg_t uartConfig;
uartConfig.configured = TRUE;
uartConfig.baudRate = HAL_UART_BR_115200;
uartConfig.flowControl = HAL_UART_FLOW_OFF;
uartConfig.flowControlThreshold = 4;
uartConfig.rx.maxBufSize = 128;
uartConfig.tx.maxBufSize = 128;
uartConfig.idleTimeout = 6;
uartConfig.intEnable = FALSE;
uartConfig.callBackFunc = NULL;
HalUARTOpen(HAL_UART_PORT_1,&uartConfig);
HalUARTWrite(HAL_UART_PORT_1, str, 15);

How could I set the pin I use? I'm using P1_6 and P1_7, I don't find how to define the pin I use. I only found
/* Ports */
#define HAL_UART_PORT_0 0x00
#define HAL_UART_PORT_1 0x01
#define HAL_UART_PORT_MAX 0x02
in the file hal_uart.h.

0 YiKai Chen over 9 years ago in reply to frank li99

Guru 735685 points

When you call HalUARTOpen with HAL_UART_PORT_1, it would setup P1.6 and P1.7 for you.

I tried to use HAL_UART_PORT_1 in my GenericApp_Init(byte task_id) and unsigned char str[]="Hello everybody";
GenericApp_TaskID = task_id;
GenericApp_TransID = 0;
GenericApp_NwkState = DEV_INIT;
halUARTCfg_t uartConfig;

GenericApp_DstAddr.addrMode = (afAddrMode_t)AddrNotPresent;
GenericApp_DstAddr.endPoint = 0;
GenericApp_DstAddr.addr.shortAddr = 0;

GenericApp_epDesc.endPoint = GENERICAPP_ENDPOINT;
GenericApp_epDesc.task_id = &GenericApp_TaskID;
GenericApp_epDesc.simpleDesc = (SimpleDescriptionFormat_t *)&GenericApp_SimpleDesc;
GenericApp_epDesc.latencyReq = noLatencyReqs;
afRegister(&GenericApp_epDesc);

GenericApp_Group.ID = 0x0001;
GenericApp_Group.name[0] = 6;
osal_memcpy(&(GenericApp_Group.name[1]),"Group1",6);

uartConfig.configured = TRUE;
uartConfig.baudRate = HAL_UART_BR_115200;
uartConfig.flowControl = HAL_UART_FLOW_OFF;
uartConfig.flowControlThreshold = 4;
uartConfig.rx.maxBufSize = 128;
uartConfig.tx.maxBufSize = 128;
uartConfig.idleTimeout = 6;
uartConfig.intEnable = FALSE;
//uartConfig.callBackFunc = rxCB;
uartConfig.callBackFunc = NULL;
HalUARTOpen(HAL_UART_PORT_1,&uartConfig);
HalUARTWrite(HAL_UART_PORT_1,str,16);
HalUARTWrite(HAL_UART_PORT_1,str,16);
HalUARTWrite(HAL_UART_PORT_1,str,16);

But when I run the program , I found that str was not output . All I got in the terminal is "H▒IEEE: 00124B00019C2EF5▒▒A▒▒▒H▒ZigBee Coord Network ID: 86FB". All these stuffs comes from the funciton void nwk_Status( uint16 statusCode, uint16 statusValue ). And I still found if I did not enter ZTOOL_P1 in the Preprocessor of Option, nothing output in the terminal. That's why?

Try to disable ZTOOL_P1 and MT_TASK in Defined symbols.

0 frank li99 over 9 years ago in reply to YiKai Chen

I disabled ZTOOL_P1 and MT_TASK in Defined symbols.But I got such link error:
Error[e104]: Failed to fit all segments into specified ranges. Problem discovered in segment XDATA_N. Unable to place 2 block(s) (0xc02 byte(s) total) in 0xa89 byte(s) of memory. The problem
occurred while processing the segment placement command "-P(XDATA)XDATA_N=_XDATA_START-_XDATA_END", where at the moment of placement the available memory ranges were
"XDATA:1477-1eff"

I don't think this is caused by removing those two Defined symbols. I remove it from my GenericApp example and don't see the same problem. I think you might use a large array to cause this issue.

0 frank li99 over 9 years ago in reply to YiKai Chen

Intellectual 640 points

You are right. I changed the options--General options--Stack/Heap--XDATA value, and the link error was gone. Thank you.
But I still not get the output in terminal. BTW, now I'm using smartRF05EB to debug the program. Now there are nothing in the terminal.

0 YiKai Chen over 9 years ago in reply to frank li99

Guru 735685 points

You have to define ZTOOL_P2 in Defined symbols.

0 frank li99 over 9 years ago in reply to YiKai Chen

Intellectual 640 points

Would you please to tell me the value in option->Stack/Heap. Such as Stack sizes and Heap sizes. I always get warning when I debug the program and use "Break" in Debug menu, which said "The stack point for stack'XdataStack'(currently XData:0x0000) is outside the stack range(Xdata:0x0001 to XData:0x300).

Thank you. Now I debug the program in smartRF05EB board. I make sure that I run the HalUARTWrite(HAL_UART_PORT1,uartbuf,16)function, but still nothing in the terminal. Now I use USB2RS232 line to connect the RS232 interface in smartRF05EB board . Here is my defined symbols:

xZTOOL_P1
xMT_TASK
ZTOOL_P2
MT_SYS_FUNC
MT_ZDO_FUNC
LCD_SUPPORTED=DEBUG
HAL_LCD=FALSE
HAL_UART=TRUE
HAL_DMA=TRUE

0 YiKai Chen over 9 years ago in reply to frank li99

Guru 735685 points

Try to remove the following defines.

HAL_LCD=FALSE
HAL_UART=TRUE
HAL_DMA=TRUE

0 frank li99 over 9 years ago in reply to YiKai Chen

Intellectual 640 points

After I tried, I found only when the Defined symbols: MT_TASK, ZTOOL_P1, and HalUARTOpen(HAL_UART_PORT_0,&uartConfig);
HalUARTWrite(HAL_UART_PORT_0,uartbuf,16); that I could get the serial output in the termainal.
If I disable the ZTOOL_P1, only start ZTOOL_P2, and HalUARTOpen(HAL_UART_PORT_1,&uartConfig);
HalUARTWrite(HAL_UART_PORT_1,uartbuf,16); I still could not get the output.

Can you show me how you connect P1.6 to your USB-to-Serial converter?

0 frank li99 over 9 years ago in reply to YiKai Chen

Intellectual 640 points

You are right. I implemented the UART1 output in my own board by using p1.6 and P1.7. I still have another question. "▒▒Hello everybody▒A▒" is what I got in the serail port. "Hellow everybody" is what I use HalUARTWrite to output. But other string I don't know where comes from.

0 YiKai Chen over 9 years ago in reply to frank li99

Guru 735685 points

I had tested the same HalUARTWrite with GenericApp and don't see garbage characters except "Hello everybody". Where do you put HalUARTWrite in your code?

Try to put "HalUARTWrite(HAL_UART_PORT_1,uartbuf,16);" to your GenericApp_HandleKeys and press any button to make it do UART write. See if you still see garbage characters.

In our customer board, there is no key and LCD. So I just could test it in status change function.

0 YiKai Chen over 9 years ago in reply to frank li99

Guru 735685 points

Try to make a high/low change on P0.1 of your custom board which can issue a key event.

0 frank li99 over 9 years ago in reply to YiKai Chen

Intellectual 640 points

I tried the status change. But at the beginning there was still the strange characters. I asked the hardware engineer, he told me that maybe the ground line of serial not good.

If you still see this problem, I would suspect there is HW connection problem there.
