I am using 280025.I learn about that 28002x series have FPU. After I get ADC conversin value,I need to calculate the digital value to physical value.I write the code as following:
If I just declare this funcition but don’t use it,after I compile,relative advice will appear as following:
"../App_User/ADC_App.c", line 14 (col. 22): advice #3195-D: (Performance) EABI double precision is 64-bits as opposed to 32-bits for COFF. Consider changing doubles to floats for improved performance in FPU32-mode.
If I use this code in some place such as interrupt, after I compile,Some problems will appear as following:
Later,I referred to “Fast Run Time Support Library user’s guide.pdf”,I changed some cofigurations as following:
Shall I need to call functions from rts2800_fpu32_fast_supplement_eabi.lib or IQmath_fpu32_eabi.lib to finish multiplication and division calculation?What should I do furthermore?
