From 0ce2950d811b8dc11e46602e7490d795d8ddfb5d Mon Sep 17 00:00:00 2001 From: Dean Camera Date: Mon, 8 Nov 2010 03:41:48 +0000 Subject: Added board hardware driver support for the Adafruit U4 breakout board. Fixed calculation of timer register reload values derived from F_CPU; must subtract one from the division result for the compare value to be correct. Change AVRISP-MKII rescue clock speed to 4MHz to ensure that a 125KHz ISP speed works regardless of the target's fuses (i.e. DIV8 set). --- LUFA/Common/BoardTypes.h | 3 + LUFA/Drivers/Board/ADAFRUITU4/LEDs.h | 129 +++++++++++++++++++++++++++++++++++ LUFA/Drivers/Board/LEDs.h | 2 + LUFA/ManPages/ChangeLog.txt | 1 + 4 files changed, 135 insertions(+) create mode 100644 LUFA/Drivers/Board/ADAFRUITU4/LEDs.h (limited to 'LUFA') diff --git a/LUFA/Common/BoardTypes.h b/LUFA/Common/BoardTypes.h index 602f46207..b5061dc09 100644 --- a/LUFA/Common/BoardTypes.h +++ b/LUFA/Common/BoardTypes.h @@ -131,6 +131,9 @@ /** Selects the Minimus specific board drivers, including the Button and LEDs drivers. */ #define BOARD_MINIMUS 22 + /** Selects the Adafruit U4 specific board drivers, including the Button and LEDs drivers. */ + #define BOARD_ADAFRUITU4 23 + #if !defined(__DOXYGEN__) #define BOARD_ BOARD_NONE diff --git a/LUFA/Drivers/Board/ADAFRUITU4/LEDs.h b/LUFA/Drivers/Board/ADAFRUITU4/LEDs.h new file mode 100644 index 000000000..39b625695 --- /dev/null +++ b/LUFA/Drivers/Board/ADAFRUITU4/LEDs.h @@ -0,0 +1,129 @@ +/* + LUFA Library + Copyright (C) Dean Camera, 2010. + + dean [at] fourwalledcubicle [dot] com + www.lufa-lib.org +*/ + +/* + Copyright 2010 Dean Camera (dean [at] fourwalledcubicle [dot] com) + + Permission to use, copy, modify, distribute, and sell this + software and its documentation for any purpose is hereby granted + without fee, provided that the above copyright notice appear in + all copies and that both that the copyright notice and this + permission notice and warranty disclaimer appear in supporting + documentation, and that the name of the author not be used in + advertising or publicity pertaining to distribution of the + software without specific, written prior permission. + + The author disclaim all warranties with regard to this + software, including all implied warranties of merchantability + and fitness.
