[Solved] Print out the value uint8_t * 9to5Answer

WebSo, bit_value = ( (uint8_variable>>BIT_NEEDED)&1) So this would shift the bit you need in LSB position, and the & operator would mask the other bits. Example: uint8_variable = 0110 1010 BIT_NEEDED=3 0110 1010 >> 3 = 0000 1101 0000 1101 & 0000 0001 = 0000 0001. I think this should work properly. Remember to count bits from 0. Share. Cite. Follow. WebYou cannot directly compare an int8_t and an uint8_t. Arithmetic always has to be done on variables of identical type. And that type has to be integer sized or greater. The size is fixed first. int can represent the range of values that a and b can hold. So both a and b are promoted to int.
