WebI must admit I don't get a warning when compiling with the Arduino IDE, however there is certainly the potential for truncation. A test program written in C++ and compiled with the -Wconversion flag gives a suitable warning: warning: conversion to ‘uint8_t {aka unsigned char}’ from ‘int’ may alter its value [-Wconversion]

O.3 — Bit manipulation with bitwise operators and bit masks

WebProblem with uint8_t. uint8_t is a typedef for unsigned char in C++. Due to this, ostream class (used for cout) prints the character having ascii numeric value (in this case 4). Hence, it is not possible to print the numeric value of a uint8_t variable directly. There are work-arounds which we have presented in this article at OpenGenus. 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. 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.
