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/st77xx/qp_st7789.h | 44 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 44 insertions(+) create mode 100644 drivers/painter/st77xx/qp_st7789.h (limited to 'drivers/painter/st77xx/qp_st7789.h') diff --git a/drivers/painter/st77xx/qp_st7789.h b/drivers/painter/st77xx/qp_st7789.h new file mode 100644 index 0000000000..ec61f5d70b --- /dev/null +++ b/drivers/painter/st77xx/qp_st7789.h @@ -0,0 +1,44 @@ +// Copyright 2021 Paul Cotter (@gr1mr3aver) +// Copyright 2021 Nick Brassel (@tzarc) +// SPDX-License-Identifier: GPL-2.0-or-later + +#pragma once + +#include "gpio.h" +#include "qp_internal.h" + +//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// +// Quantum Painter ST7789 configurables (add to your keyboard's config.h) + +#ifndef ST7789_NUM_DEVICES +/** + * @def This controls the maximum number of ST7789 devices that Quantum Painter can communicate with at any one time. + * Increasing this number allows for multiple displays to be used. + */ +# define ST7789_NUM_DEVICES 1 +#endif + +// Additional configuration options to be copied to your keyboard's config.h (don't change here): + +// If you know exactly which offsets should be used on your panel with respect to selected rotation, then this config +// option allows you to save some flash space -- you'll need to invoke qp_set_viewport_offsets() instead from your keyboard. +// #define ST7789_NO_AUTOMATIC_VIEWPORT_OFFSETS + +//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// +// Quantum Painter ST7789 device factories + +#ifdef QUANTUM_PAINTER_ST7789_SPI_ENABLE +/** + * Factory method for an ST7789 SPI LCD device. + * + * @param panel_width[in] the width of the display panel + * @param panel_height[in] the height of the display panel + * @param chip_select_pin[in] the GPIO pin used for SPI chip select + * @param dc_pin[in] the GPIO pin used for D/C control + * @param reset_pin[in] the GPIO pin used for RST + * @param spi_divisor[in] the SPI divisor to use when communicating with the display + * @param spi_mode[in] the SPI mode to use when communicating with the display + * @return the device handle used with all drawing routines in Quantum Painter + */ +painter_device_t qp_st7789_make_spi_device(uint16_t panel_width, uint16_t panel_height, pin_t chip_select_pin, pin_t dc_pin, pin_t reset_pin, uint16_t spi_divisor, int spi_mode); +#endif // QUANTUM_PAINTER_ST7789_SPI_ENABLE -- cgit v1.2.3
