Hello,
i have some problem about double!
Through terminal there is some query, that i should give some number.
for example how much delay in per hour.
if i give through terminal a number 1.1 h then it printed about -1173000!
It shall print only 1.1.
And i think, maybe there is some problem about makefile from FreeRTOS.
( because it doesn’t compiler through FreeRTOS to STM32F407 Processor! )
And I believe something throug this line shall be solved!
– CPU = -mcpu=cortex-m4 -mthumb -mfloat-abi=softfp -mfpu=fpv4-sp-d16
Please I need help, thanks
here is the fully Code of Makefile:
Optimization level, can be [0, 1, 2, 3, s].
0 = turn off optimization. s = optimize for size.
OPT = 0

Warning: this will be removed by make clean!
