From 1f2b1dedccdf21b629c45ece80b4ca32f6653296 Mon Sep 17 00:00:00 2001 From: Nick Brassel Date: Wed, 13 Apr 2022 18:00:18 +1000 Subject: Quantum Painter (#10174) * Install dependencies before executing unit tests. * Split out UTF-8 decoder. * Fixup python formatting rules. * Add documentation for QGF/QFF and the RLE format used. * Add CLI commands for converting images and fonts. * Add stub rules.mk for QP. * Add stream type. * Add base driver and comms interfaces. * Add support for SPI, SPI+D/C comms drivers. * Include when enabled. * Add base support for SPI+D/C+RST panels, as well as concrete implementation of ST7789. * Add support for GC9A01. * Add support for ILI9341. * Add support for ILI9163. * Add support for SSD1351. * Implement qp_setpixel, including pixdata buffer management. * Implement qp_line. * Implement qp_rect. * Implement qp_circle. * Implement qp_ellipse. * Implement palette interpolation. * Allow for streams to work with either flash or RAM. * Image loading. * Font loading. * QGF palette loading. * Progressive decoder of pixel data supporting Raw+RLE, 1-,2-,4-,8-bpp monochrome and palette-based images. * Image drawing. * Animations. * Font rendering. * Check against 256 colours, dump out the loaded palette if debugging enabled. * Fix build. * AVR is not the intended audience. * `qmk format-c` * Generation fix. * First batch of docs. * More docs and examples. * Review comments. * Public API documentation. --- drivers/painter/tft_panel/qp_tft_panel.h | 67 ++++++++++++++++++++++++++++++++ 1 file changed, 67 insertions(+) create mode 100644 drivers/painter/tft_panel/qp_tft_panel.h (limited to 'drivers/painter/tft_panel/qp_tft_panel.h') diff --git a/drivers/painter/tft_panel/qp_tft_panel.h b/drivers/painter/tft_panel/qp_tft_panel.h new file mode 100644 index 0000000000..6eddfc503d --- /dev/null +++ b/drivers/painter/tft_panel/qp_tft_panel.h @@ -0,0 +1,67 @@ +// Copyright 2021 Nick Brassel (@tzarc) +// SPDX-License-Identifier: GPL-2.0-or-later + +#include "color.h" +#include "qp_internal.h" + +#ifdef QUANTUM_PAINTER_SPI_ENABLE +# include "qp_comms_spi.h" +#endif // QUANTUM_PAINTER_SPI_ENABLE + +//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// +// Common TFT panel implementation using D/C, and RST pins. + +typedef uint16_t (*rgb888_to_native_uint16_t)(uint8_t r, uint8_t g, uint8_t b); + +// Driver vtable with extras +struct tft_panel_dc_reset_painter_driver_vtable_t { + struct painter_driver_vtable_t base; // must be first, so it can be cast to/from the painter_driver_vtable_t* type + + // Conversion function for palette entries + rgb888_to_native_uint16_t rgb888_to_native16bit; + + // Number of bytes for transmitting x/y coordinates + uint8_t num_window_bytes; + + // Whether or not the x/y coords should be swapped on 90/270 rotation + bool swap_window_coords; + + // Opcodes for normal display operation + struct { + uint8_t display_on; + uint8_t display_off; + uint8_t set_column_address; + uint8_t set_row_address; + uint8_t enable_writes; + } opcodes; +}; + +// Device definition +typedef struct tft_panel_dc_reset_painter_device_t { + struct painter_driver_t base; // must be first, so it can be cast to/from the painter_device_t* type + + union { +#ifdef QUANTUM_PAINTER_SPI_ENABLE + // SPI-based configurables + struct qp_comms_spi_dc_reset_config_t spi_dc_reset_config; +#endif // QUANTUM_PAINTER_SPI_ENABLE + + // TODO: I2C/parallel etc. + }; +} tft_panel_dc_reset_painter_device_t; + +//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// +// Forward declarations for injecting into concrete driver vtables + +bool qp_tft_panel_power(painter_device_t device, bool power_on); +bool qp_tft_panel_clear(painter_device_t device); +bool qp_tft_panel_flush(painter_device_t device); +bool qp_tft_panel_viewport(painter_device_t device, uint16_t left, uint16_t top, uint16_t right, uint16_t bottom); +bool qp_tft_panel_pixdata(painter_device_t device, const void *pixel_data, uint32_t native_pixel_count); +bool qp_tft_panel_palette_convert(painter_device_t device, int16_t palette_size, qp_pixel_t *palette); +bool qp_tft_panel_append_pixels(painter_device_t device, uint8_t *target_buffer, qp_pixel_t *palette, uint32_t pixel_offset, uint32_t pixel_count, uint8_t *palette_indices); + +uint16_t qp_rgb888_to_rgb565(uint8_t r, uint8_t g, uint8_t b); +uint16_t qp_rgb888_to_rgb565_swapped(uint8_t r, uint8_t g, uint8_t b); +uint16_t qp_rgb888_to_bgr565(uint8_t r, uint8_t g, uint8_t b); +uint16_t qp_rgb888_to_bgr565_swapped(uint8_t r, uint8_t g, uint8_t b); -- cgit v1.2.3
