Issue with word Data Type When Porting Arduino Library to STM32

Hi @Middleware & OS I am porting some Arduino library code to STM32 and encountering issues with the

word

word

data type. The compiler gives me the error: "expected expression before 'word'". Here is the code:

uint8_t au8Buffer[MAX_BUFFER];
uint16_t *au16regs;
....
if(i % 2)
{
    au16regs[i / 2] = word(au8Buffer[i + u8byte], lowByte(au16regs[i / 2]));
}

uint8_t au8Buffer[MAX_BUFFER];
uint16_t *au16regs;
....
if(i % 2)
{
    au16regs[i / 2] = word(au8Buffer[i + u8byte], lowByte(au16regs[i / 2]));
}

The Arduino compiler does not produce an error for this code. Do you have any suggestions?

I tried replacing

word

word

with

unsigned short

unsigned short

uint16_t

uint16_t

, but the error persists.

Solution

@Sterling The issue arises because

word

word

is a specific data type and function in the Arduino environment, which may not be directly available or compatible with STM32 libraries.
