- Tue Apr 14, 2015 5:56 pm #14527 Thanks for that. I had to use
extern "C" {
#include "user_interface.h"
uint16 readvdd33(void);
}
Otherwise I got a compiler error.
I want to read vdd33 into a variable

Code: Select allvdd33 = readvdd33

But what do I declare vdd33 as? If I use uint16 I get this error :-

Code: Select all error: invalid conversion from 'uint16 (*)() {aka short unsigned int (*)()}' to 'uint16 {aka short unsigned int}' [-fpermissive]

Thanks

- Wed Apr 15, 2015 3:29 am #14555 You need brackets e.g.

vdd33 = readvdd33();

If I put

Code: Select allint vdd33;

I get

Code: Select allerror: invalid conversion from 'uint16 (*)() {aka short unsigned int (*)()}' to 'int' [-fpermissive]
