I am transfering a part of code from one MCU vendor (Atmel xmega32E5) to Freescale/NXP MC9S08PA8 MCU ,
and when I use the log function from math.h (i hope like other IDEs does) the MCU "hits" endless restarts.
If i comment this line, MCU does its supposed job without any issue and i can see an ADC result on debugger crystal clear.
unsigned int temp;
System_Init(); //Initialise system hardware/software modules
temp=ADC_Get_Sample(CH11); //Read current channel ADC value (54us@8MHz)
ftemp=log(((10240000/temp) - 10000)); //Endless restart occurs - CRITICAL point
1) How /When do i update/include the "math.h" or similar (?) library header ?
2) Does this IDE support floats and doubles for "small ones" like the PA16 MCU?
(I have chosen at the beggining bareboard project with IIEE 64bit float support)
