warning: left shift count >= width of type [-Wshift-count-overflow]

Question

i got this problem? warning: left shift count >= width of type [-Wshift-count-overflow] *sensor_time = (uint32_t)((msb << 16) | (xlsb << 8) | lsb);

Answer 1

long may be a 32-bit or 64-bit type depending on your system, 1 is still an int. You need to make 1 a long int using the L suffix as shown below:

try code below

unsigned long x = 1UL << 32;

or

unsigned long long x = 1ULL << 32
