[SOLVED] error: large integer implicitly truncated to unsigned type

sajnanazeer · 08-18-2011, 06:22 AM

Hi,

My program is doing an i2c page read operation. The function declaration is:

Quote:

int PageRead( uint8_t address, uint8_t reg, uint8_t length, uint8_t* pBuffer );

I am calling this function from my main like this:

Quote:

uint8_t length = 10;
uint8_t buf[2][20];
uint8_t addr = 0x50;
uint8_t reg = 0x00;

ret = PageRead( addr, reg, length, buf[0]);

I am trying to compile my program and getting error from the line calling PageRead:

Quote:

error: large integer implicitly truncated to unsigned type

I am compiling with options -c -fPIC -g -O2 -m64 -Werror -Wcomments -Wreturn-type -Wsign-compare -Wall .

Can anyone help me to fix this?

Thanks in advance,
Sajna

Hi

What is the type of "ret"? If it's not int, that would explain it.

How about publishing full source code ?

Hi... Thanks for your response.

ret is an int variable. It is used for checking return status.

I did find my mistake.. One of my argument to the function was not uint8_t. It was a #define macro. That's why I am getting that error.

Thanks for all replies...
