Hi all,

I am still working on the stepper tilt project,
I am looking to do the following:

1) recieve an ascii string (similar to nmea) on a port pin serially from
a signal conditioning board, the string loks loke this in hyperterminal:

$ 0.00,16112.95,21.96,N6374

2) I need to parse this string and keep only the 16112.95 value or whatever value it happens to be.

3) I need to take this value and compare it to a stored value and if it is less
it sends the appropriate count to a port pin as pulses to a stepper driver

4) I also need it to determine the sign of the number and output a high for + and a low for -.

Currently I am using a 16F627A, There are a few more things needed but this is the main parts.

Help!!!!
