My USART problems..

[mackrackit]

I have never tried DEFINE_BAUD
maybe that was the problem.

Hmm, now I have problem with reading from the USART instead..

I searched the forum and found ALOT of threads, but none that really solved my prob..

I want to read a string of chars, like 16, BUT if a CR (13) occurs it should skip the rest.

I.e I want to be able to write strings UP to 16 chars in my terminal program, and get them as a string or array.

This seem to be a bit harder than I first thought ?

It was very easy to read single chars with HSERIN.. and I thiought it would be easy with something like

HSERIN [ str rxarr\16\13 ]

..But no ?

Does anyone have a bit of sample code that do this using HSERIN ?

[mackrackit]

Have you used SEROUT2/SERIN2 much? The hardware command use the same syntax.

Off the top I would try
$d
in place of
13

What exactly is or is not happening?

Well, I havent used SERIN, never really had use of the serial stuff before.

Now I have:

main:

HSERIN [ str rxarr\8\13 ]
LCDOUT $FE, 1, "Serial data is:"
LCDOUT $FE, $C0, rxarr
pause 500
goto main:


..This just print the first char I write.. I want rxarr to contain eight chars.

btw I found this on melabs website, which made me even more confused..

I think I see what you need. When you use the STR thing it is creating an array. Here is an example.

SERIN2 PORTB.5,24972,[WAIT("A"),STR NUMS\16]	'7, Even
X1 = (NUMS[1])
X2 = (NUMS[3])
X3 = (NUMS[5])
X4 = (NUMS[7])
X5 = (NUMS[9])
X6 = (NUMS[11])
X7 = (NUMS[13])
X8 = (NUMS[15])

the above is saving a 16 character array but I only want every other bit. Now I have eight variables X1 to X8. Do what ever you need with them.

Sorry for the poor example but it is what I have with me.
