Binary / Bitwise Calculator

Purpose

Use this tool to inspect a value's bit pattern, convert it between decimal, hex, binary, and octal, and separately run bitwise operations on two operands before writing firmware or register logic.

Main steps

1. 1Choose the bit width (8, 16, or 32-bit). It applies to both the value converter and the calculator below, including two's complement for negative decimal input.
2. 2In the value converter, pick the base of the value you already have and type it in to see all four formats and the bit grid. Click a bit to flip it, or hover to see its position.
3. 3Copy any of the four formats, or generate a C #define and typed variable for that value right there.
4. 4In the Calculator section, enter Operand A and Operand B directly (both decimal), or click "Use current value" to copy the value converter's value into Operand A.
5. 5Pick an operation. AND, OR, and XOR use Operand B as a value; shift and rotate use it as the shift amount. NOT only uses Operand A. Copy the result once it looks right.
