I am working on coming up to speed on the HI TEC C compiler so let me see what you have. I went with the basic because the tool was already here. I don't really have any loyalty to it.

With respect to the value range of the A2D , it will be fine for what I am doing. Right now I go from...
I ran the first code in my spreadsheet and it works well. However I do not understand the pic well enough to actually translate this into actual pic basic. I am sorry, I am learning just really slow!
y = 0.0304x2 - 0.0994x + 166.22 From the excel work I have done,
X = KNOTS
Y = BINARY VALUE from about 145 to 960
The binary value is the result from the 10 bit conversion. The knots are values that I have pre calculated from the Motorola data sheet (MPX5010 Differential transducer)and some...
I am working with the results of the A to D and I need to convert the voltage value to airspeed. I have the equations but most require floating point or some form of exponential math. I don't think the pic can do that. So my next option is to merely do a look up based on whatever value I read...
I am coming from the 68hc world into the pic world. One of my old tricks was to use a delay loop to operate a pin to drive an RC servo. Worked pretty good. I tried the same trick on the PIC877a and it is completely unstable. The wave form jitters and varies in duration. Power supply is a bench...
