这是我改成软件触发了，在IOC中断里触发，可以实现传输一个字符。
我改成IOC触发就不行了。会丢失几个数。间隔的丢。。。好奇怪啊。
谁能搞定这个功放发个帖分享一下。

void LED(void)
{
LED_Toggle();
DMA1_TransferStart();

// If using interrupts in PIC18 High/Low Priority Mode you need to enable the Global High and Low Interrupts
// If using interrupts in PIC Mid-Range Compatibility Mode you need to enable the Global Interrupts
// Use the following macros to:

INTERRUPT_GlobalInterruptEnable();
// Disable the Global Interrupts

SW_SetInterruptHandler(LED);
printf("Hello \n");
for(uint8_t i=0;i<10;i++)
{
srcVarName1[i]='1'+i;

{
putch(srcVarName1[i]);
}
putch('\n');
while(1)
