From: ayer1 Date: Tue, 16 Mar 2010 15:17:19 +0000 (+0000) Subject: all new code largely related to supporting the fatfs addition and a X-Git-Url: https://oss.titaniummirror.com/gitweb/?p=tinyos-2.x.git;a=commitdiff_plain;h=8f4a44d868701f70463103fabc14fe78c452057f all new code largely related to supporting the fatfs addition and a contrib app, justfatlogging. localtime64 is to keep localtime from wrapping timestamps every 31 hours. shimmeranalogsetup is a wrapper for old tos-1.x dma/adc stuff to enable quick app setup and conversion. powersupply monitor is an old attempt to make use of msp430 utility. --- diff --git a/tos/platforms/shimmer/.platform b/tos/platforms/shimmer/.platform index 1a3a7e8d..59f3fe6d 100644 --- a/tos/platforms/shimmer/.platform +++ b/tos/platforms/shimmer/.platform @@ -13,8 +13,10 @@ push( @includes, qw( %T/platforms/shimmer/chips/cc2420 %T/platforms/shimmer/chips/mma7260 %T/platforms/shimmer/chips/sd + %T/platforms/shimmer/chips/sd/fatfs %T/platforms/shimmer/chips/bluetooth %T/platforms/shimmer/chips/msp430 + %T/platforms/shimmer/chips/ds2411 %T/chips/cc2420 %T/chips/cc2420/alarm %T/chips/cc2420/control diff --git a/tos/platforms/shimmer/Counter32khz64C.nc b/tos/platforms/shimmer/Counter32khz64C.nc new file mode 100644 index 00000000..e66c8f6f --- /dev/null +++ b/tos/platforms/shimmer/Counter32khz64C.nc @@ -0,0 +1,52 @@ + +/* "Copyright (c) 2000-2003 The Regents of the University of California. + * All rights reserved. + * + * Permission to use, copy, modify, and distribute this software and its + * documentation for any purpose, without fee, and without written agreement + * is hereby granted, provided that the above copyright notice, the following + * two paragraphs and the author appear in all copies of this software. + * + * IN NO EVENT SHALL THE UNIVERSITY OF CALIFORNIA BE LIABLE TO ANY PARTY FOR + * DIRECT, INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES ARISING OUT + * OF THE USE OF THIS SOFTWARE AND ITS DOCUMENTATION, EVEN IF THE UNIVERSITY + * OF CALIFORNIA HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGE. + * + * THE UNIVERSITY OF CALIFORNIA SPECIFICALLY DISCLAIMS ANY WARRANTIES, + * INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY + * AND FITNESS FOR A PARTICULAR PURPOSE.

These are +incorporated here. + +First note: Your app must call mount before proceeding with any other file +operations. Boot.booted is a good place to do this. + +Application developers should note that FatFs development used the IP +stack and NTP updates in order to provide accurate timestamps. +tinyos-1.x/contrib/handhelds/swtest/TestFATLogging shows how to do this. + +Without these mechanisms, an application will need another method to +seed the app's time value with something realistic (not +1/1/1980-relative) at compile time, or devise a way to provide a +runtime update from a host. + +One way: +------- +copy the simple python script timeSec.py in tinyos-2.x-contrib/shimmer/apps/JustFATLogging to your +app directory. + +add these lines to your app's Makefile, which will provide a hook for +the the compile time variable CURRENT_TIME. TimeP uses this to set the +runtime g_current_time that sets the baseline for reporting localtime +on the device: + +ifdef CURRENT_TIME +PFLAGS += -DCURRENT_TIME=$(CURRENT_TIME) +endif + +then, at compile-time, add CURRENT_TIME=`python ./timeSec.py` to the +build line. + +unfortunately, this seed will be restored if you reset the board. + +Another way: +----------- +add a mechanism to provide the current time from a host machine via +serial line. one example of how to do this is in +tinyos-1.x/contrib/handhelds/apps/ThreeAxisRecorder. + +Yet Another way: +--------------- +use the bluetooth radio to do similar (don't know why this would be +easier than using the built-in access point-ip stack +infrastructure...). + + + + + + diff --git a/tos/platforms/shimmer/chips/sd/fatfs/ccsbcs.c b/tos/platforms/shimmer/chips/sd/fatfs/ccsbcs.c new file mode 100644 index 00000000..57439b2e --- /dev/null +++ b/tos/platforms/shimmer/chips/sd/fatfs/ccsbcs.c @@ -0,0 +1,540 @@ +/*------------------------------------------------------------------------*/ +/* Unicode - Local code bidirectional converter (C)ChaN, 2009 */ +/* (SBCS code pages) */ +/*------------------------------------------------------------------------*/ +/* 437 U.S. (OEM) +/ 720 Arabic (OEM) +/ 1256 Arabic (Windows) +/ 737 Greek (OEM) +/ 1253 Greek (Windows) +/ 1250 Central Europe (Windows) +/ 775 Baltic (OEM) +/ 1257 Baltic (Windows) +/ 850 Multilingual Latin 1 (OEM) +/ 852 Latin 2 (OEM) +/ 1252 Latin 1 (Windows) +/ 855 Cyrillic (OEM) +/ 1251 Cyrillic (Windows) +/ 866 Russian (OEM) +/ 857 Turkish (OEM) +/ 1254 Turkish (Windows) +/ 858 Multilingual Latin 1 + Euro (OEM) +/ 862 Hebrew (OEM) +/ 1255 Hebrew (Windows) +/ 874 Thai (OEM, Windows) +/ 1258 Vietnam (OEM, Windows) +*/ + +//#include "../ff.h" + + +#if _CODE_PAGE == 437 +#define _TBLDEF 1 +static +const WCHAR Tbl[] = { /* CP437(0x80-0xFF) to Unicode conversion table */ + 0x00C7, 0x00FC, 0x00E9, 0x00E2, 0x00E4, 0x00E0, 0x00E5, 0x00E7, + 0x00EA, 0x00EB, 0x00E8, 0x00EF, 0x00EE, 0x00EC, 0x00C4, 0x00C5, + 0x00C9, 0x00E6, 0x00C6, 0x00F4, 0x00F6, 0x00F2, 0x00FB, 0x00F9, + 0x00FF, 0x00D6, 0x00DC, 0x00A2, 0x00A3, 0x00A5, 0x20A7, 0x0192, + 0x00E1, 0x00ED, 0x00F3, 0x00FA, 0x00F1, 0x00D1, 0x00AA, 0x00BA, + 0x00BF, 0x2310, 0x00AC, 0x00BD, 0x00BC, 0x00A1, 0x00AB, 0x00BB, + 0x2591, 0x2592, 0x2593, 0x2502, 0x2524, 0x2561, 0x2562, 0x2556, + 0x2555, 0x2563, 0x2551, 0x2557, 0x255D, 0x255C, 0x255B, 0x2510, + 0x2514, 0x2534, 0x252C, 0x251C, 0x2500, 0x253C, 0x255E, 0x255F, + 0x255A, 0x2554, 0x2569, 0x2566, 0x2560, 0x2550, 0x256C, 0x2567, + 0x2568, 0x2564, 0x2565, 0x2559, 0x2558, 0x2552, 0x2553, 0x256B, + 0x256A, 0x2518, 0x250C, 0x2588, 0x2584, 0x258C, 0x2590, 0x2580, + 0x03B1, 0x00DF, 0x0393, 0x03C0, 0x03A3, 0x03C3, 0x00B5, 0x03C4, + 0x03A6, 0x0398, 0x03A9, 0x03B4, 0x221E, 0x03C6, 0x03B5, 0x2229, + 0x2261, 0x00B1, 0x2265, 0x2264, 0x2320, 0x2321, 0x00F7, 0x2248, + 0x00B0, 0x2219, 0x00B7, 0x221A, 0x207F, 0x00B2, 0x25A0, 0x00A0 +};
