Delta Pico Simulator

This is a desktop simulator for my Delta Pico graphing calculator.

This works by providing an implementation of ApplicationFramework (the Delta Pico firmware's HAL trait), which draws to a window backed by minifb and translates keystrokes into keypad buttons.

Button Mapping

Buttons are directly mapped to their keyboard equivalents where possible (e.g. digit buttons are mapped to the number keys). Other important keys are mapped as follows:

Physical button	Keyboard key
EXE	Enter
MENU	Escape
SHIFT	Tab
LIST	Space

See the BUTTON_MAPPING constant in the source for a full list.

Usage

1. Check out the main Delta Pico repository
2. Check out this repository
3. Adjust the delta-pico-rust crate path in Cargo.toml to match the location of the rust subfolder in your main Delta Pico checkout
4. cargo run in this repository

Functionality

Most features work fine, with these (known) exceptions:

• The simulator doesn't have a bootloader
• Colours don't show up exactly the same on the simulator - what looks grey on the real thing shows up as a dark green on the simulator

Also, minifb doesn't seem to like not being updated for long periods, on macOS at least. If you move the window between displays, you might end up with artifacts until the screen updates again.

Why isn't this in the main repo?

Unfortunately, rust-analyzer does not seem to like mixed std and no-std targets in the same workspace! Including this crate in the main repository makes rust-analyzer stop working almost completely, so I've kept it separate instead, and just open a second VS Code window for this crate.
