Bit operation

[Sagisawa Yukichi]

Hello. I use nRF52 , PCA10040 , S132 , SDK 11 & Keil5.

I want nrf to do bit operation. The code about bit operation is following.

unsigned char tmp[2]; unsigned short us; tmp[0] = 0xf8; tmp[1] = 0x59; us = (tmp[0] << 8) | tmp[1]; printf("%d\r\n",us);

I thought the printf("%d\r\n",us); should output 63577, but it output another number. What is my code wrong?

Please help me.

Thanks,

BTW. I was referring to gcc a toolchain rather than the compiler (perhaps I should have made this explicit)

I don't have time to try all the different gcc libs, I suspect they all behave the same

But as a matter of interest, I compiled the code in Visual Studio, targeted for Win32 and it also works fine.

I don't have any other 32 bit compilers, but perhaps someone else has IAR and can confirm the behavior under that toolchain

Perhaps the OP can try the different libs in Keil
