progcalc

This is a programmer's calculator for KnightOS.

Functionality

It currently supports 32bit Decimal, Hexadecimal and Binary entry and conversion.

For the mathematical operations, the first number that is entered is always 32bit while the second number will be truncated before the operation.

Primary:

• Addition
  • 32bit + 16bit
• Subtraction
  • 32bit - 16bit
• Multiplication
  • 32bit * 8bit
• Division
  • 32bit / 16bit

Secondary:

These can be reached by pressing the Graph Vars key.

• Modulo
  • 32bit mod 16bit
• Left-Shift
  • 32bit << 0-63 places
• Right-Shift
  • 32bit >> 0-63 places
• Bitwise OR
  • 32bit or 32bit
• Bitwise AND
  • 32bit and 32bit
• Bitwise XOR
  • 32bit xor 32bit

Keybindings

In keys.asm, set DEBUG to 0 for running on hardware or to 1 for running with the z80 emulator

Compiling

***Requires a version of the kernel that includes drawDecHL and drawDecACIX. ***

First, install the KnightOS SDK.

Then in the base directory of this repository, run

$ knightos init progcalc
$ make
$ make run

Use this command to compile the kernel from source

$ knightos init --kernel-source=/path/to/kernel progcalc

Installing

Using SDK

The package can be found at packages.knightos.org and installed using:

$ knightos install community/progcalc

Manual

Use make package to get a package that you can install.

To install the package in KnightOS run

$ make install PREFIX=../KnightOS/.knightos/pkgroot/

To "pin" the application to castle, add this to the makefile in KnightOS directory. Put it right after the other "pin" lines.

ln -s /var/applications/progcalc.app $(VAR)castle/pin-7
