Have you run into situation under the MPLAB IDE where you are trying to output variables, but even though you have the format correct, a float variable outputs with a .0 value?
(from somewhere else in code)
float adjustedtemp= 0.0;
adjustedtemp= (AIRTEMP + 5)/10;
printf("Air Temp: %5.2f \r\n", adjustedtemp);
the result looks like this
Air Temp: 75.00
when it SHOULD look like this
Air Temp: 75.60
this is due to a bug in the way MPLAB handles floats.
Two easy ways to fix it:
adjustedtemp= (AIRTEMP + 5.0)/10.0;
adjustedtemp= ((float)AIRTEMP + 5)/10;
Either of these methods will result in the correct value being displayed during your sprintf() or printf() command.
If you are having a problem with the MICROCHIP XC8 installer hanging on installation under Windows 10 — (see screenshot below):
Very easy solution…
Change your screen resolution to 1080p, and TURN OFF all “screen scaling/screen zooming” settings
Reboot your computer (trust me, just do this step)
The installer should work fine now.
when done, change your screen back to whatever settings you previously had it at…
let me know if this works for you. I spent 2 hours trying to figure this one out.
If you receive the following error during an XC8 project build, here is how to fix it
warning: (1472) –CODEOFFSET option ignored: duplicate or conflicting option
under project properties, XC8 Linker, make sure there is either
a) no value (blank) in the CODEOFFSET field
b) some legitimate value in CODEOFFSET that works with your bootloader
a ZERO — 0 — as pictured will cause this error during build.
if you receive the following error during BUILD in XC8, here is the quick fix:
warning: (1459) peripheral library support is missing for the 18F6722
the fix is simple:
make sure this checkbox is UNCHECKED under the project properties, XC8 linker.
