Bit Peek for Visual Studio Code

Bit Peek can display various forms (binary, hexadecimal, decimal, octal, ASCII) of numbers on a simple mouse cursor hover action, in a very easy to read format. Extension is available on the Marketplace and Open VSX Registry, compatible with Arduino IDE 2.x.

Features

Bit Peek could show bits in an unique "register friendly" mode: all the 0s will be displayed as ., so you can identify the 1s at a glance:

And it supports both LSB0 (Intel-style) and MSB0 (Motorola-style) bit numbering display:

Bit Peek will try to identify the base of numbers automatically. But if you are analyzing memory dumps, try Bit Peek: Toggle force HEX mode command to enforce parsing as hexadecimals:

For octal numbers, Bit Peek will interpret the bits as UNIX file permission when possible:

Supported Formats

Customizations

The hover content is highly configurable to suit your needs. You can customize what information is displayed in the hover tooltip by changing the following settings:

• bit-peek.showBin: Show binary value.

  • bit-peek.registerView: Show bits in a "register-friendly" mode.
  • bit-peek.msb0: Use MSB0 bit numbering (Motorola-style).

• bit-peek.showHex: Show hexadecimal value.

  • bit-peek.showWidth: Show data bit width.

• bit-peek.showStr: Show ASCII characters.

  • showAsciiCode: Show ASCII code.

• bit-peek.showDec: Show decimal value.

  • bit-peek.showSize: Show as capacity (T/G/M/K).

• bit-peek.forceHex: Enable "Force HEX" mode.

Limitations

• For the decimal numbers without base prefix and postfix, it must not begin with 0, or it will be recognized as octal (C/C++ rule).
• In some languages (C/C++/JavaScript...), the sign of decimal numbers cannot be fetched due to the limitation of Visual Studio Code, so it cannot recognize negative numbers in such case.
