CC2530串口打印的问题

看一下你uartConfig.tx.maxBufSize設置多大

能发送部分，说明接线没问题，后面没有了，说明发送缓存超额了。修改一下。改成512试试看。

那个缓存大小，默认是128的，我记得是这样，好久没用过这个了，可以修改成256,512,1024试试看。

uint16 HalUARTWriteISR(uint8 *buf, uint16 len)
{
uint16 cnt;

// Enforce all or none.
if (HalUARTTxAvailISR() < len)
{
return 0;
}

for (cnt = 0; cnt < len; cnt++)
{
isrCfg.txBuf[isrCfg.txTail] = *buf++;
isrCfg.txMT = 0;

if (isrCfg.txTail >= HAL_UART_ISR_TX_MAX-1)
{
isrCfg.txTail = 0;
}
else
{
isrCfg.txTail++;
}

// Keep re-enabling ISR as it might be keeping up with this loop due to other ints.
IEN2 |= UTXxIE;
}

return cnt;
}
感觉跟HAL_UART_ISR_TX_MAX有关，我将HAL_UART_ISR_RX_MAX 设置为384仍没有改善
#if !defined HAL_UART_ISR_RX_MAX
#define HAL_UART_ISR_RX_MAX 384
#endif
#if !defined HAL_UART_ISR_TX_MAX
#define HAL_UART_ISR_TX_MAX HAL_UART_ISR_RX_MAX
#endif

设置是uartConfig.tx.maxBufSize=512

對，還是不行。
我每次串口发送字节数小于30字节，只是连续调用了很多次HalUARTWrite。是不是应该中间有个延迟？
或者应该在某处，用一段代码把寄存器复位一下？

把你的工程打包发出来，看看TI员工有没有这个板子，帮你测试一下。

太大了，无法发送。

我記得好像不能连续调用HalUARTWrite，建議你把要輸出的信息合成一條一次只调用一個HalUARTWrite

有没有其他办法可以解决？

没有

我将其放在一个数组中，
uint8 HMI_RuWang_Word[]={ 0x70,0x61,0x67,0x65,0x31,0x2E,0x74,0x31,0x2E,0x74,0x78,0x74,0x3D,0x22,0xD2,0xD1,0xC8,0xEB,0xCD,0xF8,0x22,0xff,0xff,0xff, 0x70,0x61,0x67,0x65,0x31,0x2E,0x74,0x32,0x2E,0x74,0x78,0x74,0x3D,0x22,0xD2,0xD1,0xC8,0xEB,0xCD,0xF8,0x22,0xff,0xff,0xff, 0x70,0x61,0x67,0x65,0x31,0x2E,0x74,0x33,0x2E,0x74,0x78,0x74,0x3D,0x22,0xD2,0xD1,0xC8,0xEB,0xCD,0xF8,0x22,0xff,0xff,0xff, 0x70,0x61,0x67,0x65,0x31,0x2E,0x74,0x34,0x2E,0x74,0x78,0x74,0x3D,0x22,0xD2,0xD1,0xC8,0xEB,0xCD,0xF8,0x22,0xff,0xff,0xff, 0x70,0x61,0x67,0x65,0x31,0x2E,0x74,0x35,0x2E,0x74,0x78,0x74,0x3D,0x22,0xD2,0xD1,0xC8,0xEB,0xCD,0xF8,0x22,0xff,0xff,0xff, 0x70,0x61,0x67,0x65,0x31,0x2E,0x74,0x36,0x2E,0x74,0x78,0x74,0x3D,0x22,0xD2,0xD1,0xC8,0xEB,0xCD,0xF8,0x22,0xff,0xff,0xff
};
总共24*6=144个字节
然后用HalUARTWrite(0,HMI_RuWang_Word,sizeof(HMI_RuWang_Word));输出，串口没有显示。
经调试
HalUARTWrite(0,HMI_RuWang_Word,127);可以显示
HalUARTWrite(0,HMI_RuWang_Word,128);不显示任何数据

我的初始化函数如下：
#if !defined( MY_APP_RX_SZ )
#define MY_APP_RX_SZ 512 //串口接收最大容量
#endif
#if !defined( MY_APP_TX_SZ )
#define MY_APP_TX_SZ 512 //串口发送最大容量
#endif
void MyApp_UartInit(void)
{
halUARTCfg_t uartConfig;
uartConfig.configured = TRUE; // 2x30 don't care - see uart driver.
uartConfig.baudRate = MY_APP_BAUD;
uartConfig.flowControl = FALSE;
uartConfig.flowControlThreshold = MY_APP_THRESH; // 2x30 don't care - see uart driver.
uartConfig.rx.maxBufSize = MY_APP_RX_SZ; // 2x30 don't care - see uart driver.
uartConfig.tx.maxBufSize = MY_APP_TX_SZ; // 2x30 don't care - see uart driver.
uartConfig.idleTimeout = MY_APP_IDLE; // 2x30 don't care - see uart driver.
uartConfig.intEnable = TRUE; // 2x30 don't care - see uart driver.
uartConfig.callBackFunc = rxCB; //串口接收到数据时的处理
HalUARTOpen (HAL_UART_PORT_0, &uartConfig);
}

函数HalUARTWrite如下：
#if !defined HAL_UART_ISR_TX_MAX
#define HAL_UART_ISR_TX_MAX 512
#endif
uint16 HalUARTWriteISR(uint8 *buf, uint16 len)
{
uint16 cnt;

// Enforce all or none.
if (HalUARTTxAvailISR() < len)
{
return 0;
}

for (cnt = 0; cnt < len; cnt++)
{
isrCfg.txBuf[isrCfg.txTail] = *buf++;
isrCfg.txMT = 0;

if (isrCfg.txTail >= HAL_UART_ISR_TX_MAX-1)
{
isrCfg.txTail = 0;
}
else
{
isrCfg.txTail++;
}

// Keep re-enabling ISR as it might be keeping up with this loop due to other ints.
IEN2 |= UTXxIE;
}

return cnt;
}

请问该怎么办？很着急，是CC2530每次只能输出127个字节么？无法做任何更改？能不能给个建议

我剛剛試著作如下的修改，就可以輸出230bytes
#define MT_UART_TX_BUFF_MAX 256
#define MT_UART_RX_BUFF_MAX 256

可以了。谢谢。
但是还有一个疑问：
CC2530最多可以输出230个字节。如要要更多的话，就要人为分包发送了是么？
如果是的话，分包发送的思想是什么？能不能举个例子或者提供一个相关的链接？

127，说明问题不严重，是你没改对地方，要该跟这个函数有关的那个配置值才行。

看你现在改对了就搞定了，当初你可以跟踪那个函数的，看看那个函数原型调用了哪个宏控制了缓存大小。

我的MT_UART_TX_BUFF_MAX 只有開到256，如果開更大，要輸出多一點應該不是問題

可以考虑用指针分段传送超长的字符串。

这个没弄过，请问有没有相关的讲解或例程？

就開個週期事件，每次串口打印一小段然後更新指针，分段完成串口打印
