Calculations in PCWHD PIC Compiler!

[engr.humair]

Dear:

I am newbie for CCS PCWHD PIC compiler.

Need to know about procedure to accept byte or float from RS232 & perform arithematic calculations on it?

Thanks in advance.

Go to Drivers Directory in “C:\Program Files\PICC\Drivers” (if use default) and take a look at the file “input.c”. In this driver, it contains a function “void get_string(char* s, unsigned int8 max)”. You can use this function to get the data from RS232. After you call the “get_string()”, the string need to convert to a number; INT or HEX or DEC or FLOAT depends on the data type.

You can use:
atoi()   to convert to int
atof()      to convert to float
strtof()   to convert to float

…
Other option also available, depend on your mileage.

I am NO expert on the CCS. You should read the example in the EXAMPLES directory to understand and get more information’s.

Regards,

Tom
