From 87c0f1748868e5728d842d75490a707c8b6863ac Mon Sep 17 00:00:00 2001 From: PLSCO Date: Wed, 2 Mar 2016 14:52:59 -0800 Subject: [PATCH] Added SPI transactions support for ILI9341 Current version of the library malfunctions when another device (besides the LCD) shares the SPI bus. Implementing the modern SPI transactions method seems to have resolved it. --- Pixels.cpp | 4017 +++++++++++++++++++++++----------------------- Pixels.h | 1883 +++++++++++----------- Pixels_ILI9341.h | 522 +++--- Pixels_SPIhw.h | 853 ++++++---- 4 files changed, 3797 insertions(+), 3478 deletions(-) mode change 100644 => 100755 Pixels_ILI9341.h mode change 100644 => 100755 Pixels_SPIhw.h diff --git a/Pixels.cpp b/Pixels.cpp index a36f299..cb9803c 100755 --- a/Pixels.cpp +++ b/Pixels.cpp @@ -1,2005 +1,2012 @@ -/* - * Pixels.
