I was hoping to find on-line manuals that I could print and read on the john. So far no luck. But what I really need is how to declare variables in C.
For example, I have a sample code that has the statement:
unsigned char
and
unsigned long
What do these mean and do they limit the declaration to integers. What do i declare if I want a floating point?
Also, someone told me I cant do floating point with a Keil Compiler because of licensing issues (I got my copy from Silicon Labs and have just registered it). I will eventually need to do trig functions. What do i have to get (buy) to complete my project?
I think that's the key issue - especially with the 8051.
Because there is a 'C' compiler, newcomers don't even realise that certain features of "normal" 'C' are really not good for an 8051.
Floating point is one of the commonest, and it is generally the case that people have not even considered that there might be any issues - let alone evaluated those issues and come to the conclusion that floating point (or whatever) is "good enough" even so.
