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.
