| Another serial question |

HI Guys I have a issue reading in more than two serial bytes.
| Code: | BOOLEAN waitForResponse( int32 timeout, byte buffer[], int8 bufferLength )
{
int8 byteCnt = 0;
int32 time = 0;
while(kbhit(CAMERA)&&(++time<timeout))
{
buffer[byteCnt] = fgetc(CAMERA);
if( byteCnt == bufferLength )
{
return (1);
}
byteCnt++;
}
return (0);
} |
I'm reading in a total of 6 bytes of which the first two are always correct but the last four are garbage.
Any suggestions ??
Thx

Hi,
Yes, two suggestions:
1. Add the ERRORS directive to your #Use RS232 statement
2. Read the forum everyday as this and other similar problems are covered repeatedly here....
