Which library should I ise for 32-bit support in CW 10.6 for the MC9S08SH32 MCU ? Standard "ansis.lib" doesn't seem to work.

Hi Carol,

all  default CW for HCs08 libraries use 16bit int for integer type. long type is 32bit.

if you use floating support, we have two options when creating a new project:

user can modify type size in compiler settings:

can this help you?

Have a great day,

Hello Jennie,

I think I have resolved my issue. An additional typecast was needed before the “Temp_Code” variable which needs to be referenced as ((signed long) Temp_Code) in all calculations.

Thanks,

Carol

Hello Jennie,

I’m fine with int and long definitions in your mail. However I cannot make the following to work.

int Temp_Code;

signed long temperature;

temperature = (signed long )(Temp_Code*17572);

Expression “Temp_Code*17572” evaluates correctly in debugger but when I write the result in 32-bit variable “temperature”, I lose the upper 16 bits which remain 0. My guess was that maybe I need to use a different library to handle this.

How can I make this calculation work ?

Thanks,

Carol

hi,

I just tested your code from my side , seems it works normal. see attached video and demo code.

Have a great day,
Jennie Zhang
