As of ProffiesOS 6.x, it's possible to show bullet counts on an OLED display. Here's what you would need:
This includes the display code, but doesn't activate it. May become the default in the future.
#define INCLUDE_SSD1306
Here's how we activate the display:
#ifdef CONFIG_BOTTOM
DisplayHelper<128, uint32_t,
BaseLayerOp<StandardDisplayController>,
ClearRectangleOp<10, 80, 8, 24>,
WriteBulletCountOp<10, 20, 5>
> display_controller;
SSD1306Template<128, uint32_t> display(&display_controller);
#endif
The DisplayHelper class takes a list of display operations, which works a lot like the Layers<> style. Currently, these operations are available:
Two different base layers:
BaseLayerOp<StandardDisplayController>ClearScreenOpThe first one makes it work like a standard display controller (shows, font.bmp, messages, etc., the second one just makes it black.
ClearRectangleOp<x1, x2, y1, y2> 🔗
This op clears a rectangle on the screen.
WriteBulletCountOp<x, y, digits> 🔗
Writes the current bullet count at the specified location.
IfImageOp<OP> 🔗
This executes OP if the base layer is showing an image, but not otherwise. The idea is that you could have a bullet count that draws over images, but not messages and battery monitors.
We will probably need more display OPs real soon for other purposes... In 7.x I plan to make it possible to specify a different display controller for each preset, essentially making it a "style" for the display.
