Hi,everyone.
I was using the twrk60n512 borad.I use the serial to receive data,I found it can only receive a maximum of 8 characters a time,it would drop the the characters after the eighth character.I tested the serial in IO_SERIAL_NON_BLOCKING mode and IO_SERIAL_BLOCKING mode,it was the same.
The following was my code:
unsigned int iTimeoutCount=0;
unsigned int iRLengh=0;
unsigned char szRbuf[200];
serial_fd = _io_fopen("ttya:",(pointer)IO_SERIAL_NON_BLOCKING );
while(TRUE)
{
if (fstatus( serial_fd )) {
fread(szRbuf+iRLengh,1,1,serial_fd);
iRLengh++;
iTimeoutCount=0;
}
else
{
_time_delay(10);
iTimeoutCount++;
if(iTimeoutCount>10)
break;
}
}
I sent 10 characters to the serial from pc,I found it can only receive 8 characters,I don't konw whether there was something wrong.
