Okay,
So, I have spent a bunch of time trying to understand how I can implement the code that you showed me when I realized the issue it was probably going to create.
When the data is coming in, it comes in with these types of formats based on pressure units at a rate of 3 times per second.
Its always 21 characters.
" 9.08, PSI"
" 0.1, inH2O"
" 0.01, inHg"
" 10.5, kpa"
" 0.000, Bar"
" 1., mBar"
So basically as it sits (and if you'll take a peak at the code), It reads each byte (as long as there are more than 20 bytes available in the buffer, assigns it to a variable, and then prints only the ones that I want so that it fits nicely on the 16x2 SerLCD I am using.
Right now, it works perfectly without any flaw.
The code could be so simplified I'm sure, however it made it easy to picture what was going to happen for the output.
The reason I am asking about the converting bytes to a string value is because I want to be able to compare the numerical value of the pressure, say 10.00 psi to a stored number of say 8. This way I can have it print something else out like "high pressure alarm" or whatever.
Forgive me needing my hand held through this, I am trying, but some of the syntax isn't exactly clicking with me. Check out my code, I
m sure it's very easy to implement.
Thanks again folks.
