Graphics.getPixel(xy) on ILI9341 Module for ILI9341 LCD

Hi, I wrote a little code to read a image in bmp format and show in a display with ili9341, the code works but take about 12 seconds to show a image in 320x240, when I saw the clk pin with an oscilloscope, I saw a huge delay between the data for each pixel, I think it is because spin run very slow so maybe I need to use C compiler....
Use the ili9341.color565 function to generate this color value from red, green, blue component values. In addition to pixel drawing there's a filled rectangle drawing command called fill_rectangle.

14/09/2015 · Currently I got a lot of fun with a ILI9341 based LCD module (240x320). From the documentation I've learned to set an address window to send pixel data to the display controller. how to play kerbal space program on xbox one The Facebook pixel allows you to monitor how people interact with your website after viewing your Facebook ad. You can even track customers across their devices so you know, for example, if people tend to see your ads on mobile but switch to a desktop before making a purchase—or maybe it’s the other way around..

Ili9341 How To Read Pixel Data

6/01/2012 · Re: How to read Pixel data from the MultiSampled framebuffer Using glReadPixels is always expensive, how expensive depends on the platform. But most platforms need to stall rendering and wait for rendering to finish, with a possible resolve to another buffer, then an un-cached buffer generally needs to be read then the format needs to be converted.

  • As there is just pixel data in this file the width and height of the image must be provided to the function. The library and sketch is targetted at AVR processors (UNO, Mega etc). I do not have a DUE, so do not plan at the moment to make it compatible with ARM processors.
  • I am trying to interface with an SPI ILI9341 screen using an STM32 microcontroller. I know there are a whole lot of things that can go wrong with these interfaces, and I've spent an awful lot of time searching and solving problems.
  • Before writing data to the display call ili9341_init() Pointer to the pixel buffer to read to : count: Number of pixels to read : References Assert, ILI9341_CMD_MEMORY_READ, ILI9341_COLOR, ili9341_deselect_chip(), ili9341_read_byte(), and ili9341_send_command(). void ili9341_copy_pixels_to_screen (const ili9341_color_t * pixels, uint32_t count ) Copy pixels from …
  • 30/12/2015 · The Adafruit library version that the vendor provided did not implement reading pixel data for the ILI9341, and existing optimized ILI9341 Arduino drivers were designed for fast writing, not fast reading-and-writing. To achieve performant flicker-free 3D rendering, it was necessary to overhaul the ILI9341 driver. The modified drivers and 3D rendering engine are now hosted online at Github. A
