Parsing Strings...

[mackrackit]

From the manual:

STR followed by a byte array variable, count and optional ending
character will receive a string of characters. The string length is
determined by the count or when the optional character is
encountered in the input.

[STR smallp\10\,]
See if that will get the first part correctly.

Does the data comming in have a qualifying character before the data you want? If so then the first example I gave will work. If it does not have a qualifying character then leave that part out.

I appreciate your help! Very confused

hserIN 65535, oops, [STR smallp\10\","]

The first time thru I get the correct first part of the string. the device was sent 777,53 and smallp received 777.

The second time and every time thereafter the data is skewed. For example if the next packet that comes in is 766,59 smallp receives a 53766. The 53 from the last packet sent....

It would seem to be a lot easier to capture the whole sequence, then later scan the array for any commas and deal with it that way, especially since when you are using SERIN you have very little processing time available between characters.

[TerdRatchett]

I think that's a great suggestion and I agree. I have been unable to successfully parse it after the fact.

[TerdRatchett]

and to make matters worse I am unable to consistantly and correctly receive serial packets.

[TerdRatchett]

Well, I got the serial function working reliably by doing this:

hserIN 65535, oops, [STR smallp\12\10]

rather than this:

hserIN 65535, oops, [STR smallp\12\13]

aparently the linefeed was the last command sent, so by terminating with a carraige return, the linefeed that followed was polluting the serial stream for the next packet

[TerdRatchett]

So now that I'm just looking at a parsing issue I've changed the serial in code to:

hserIN 65535, oops, [STR smallp\5, WAIT(","), STR largep\5\10]

It doesn't work as expected. When receiving 1480,95...

STR smallp\5 actually captures 5 characters including the comma even though it's the "wait for" character. I can't make smallp\4 because sometimes the data received will be 5 characters. It could also be 3 or 2 or 1 characters.
