Ok, it’s now 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> ClearScreenOp The 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.
