Test version for Particle mesh devices

README.md

@@ -1,62 +1,27 @@
-### Warning: This beta version is now out of date. Use standard version of SdFat.
+### Warning: This beta is for testing with Particle IoT mesh devices.
 
-Teensy 3.5/3.6 SDIO support has been added.  Try the TeensySdioDemo example.
-Many other example will work with Teensy SDIO if you use the SdFatSdio classes
-and call begin with no parameters.
+This version of SdFat has been modified to use standard POSIX/Linux 
+definitions of open flags from fcntl.h.
 
-```
- SdFatSdio sd;
- 
- ....
- 
-  if (!sd.begin()) {
-    // Handle failure.
-  }
- 
-```
-
-Recent versions of the Arduino IDE have bugs that may cause SdFat-beta to crash.
-
-https://forum.arduino.cc/index.php?topic=419264.0
-
-SdFat-beta was tested using Arduino AVR boards 1.6.11. 
-If you are using IDE 1.6.11 you must also install AVR boards 1.6.11, not
-1.6.12 or 1.6.13.
-
-If you are using Arduino IDE 1.6.11, do Tools > Board > Boards Manager > Arduino AVR Boards > 1.6.11 > Install > Close.
-
-Key changes:
+Open flags are include access modes, O_RDONLY, O_RDWR, O_WRONLY, and modifiers
+O_APPEND, O_CREAT, O_EXCL, O_SYNC, O_TRUNC.
 
-The SPI divisor has been replaced by SPISettings.
+Rename this folder SdFat and place it in the standard place for libraries.
 
-There are two new classes, SdFatEX and SdFatSoftSpiEX.
+I tested with a particle CLI project with a SdFat in a lib
 
-Please read changes.txt and the html documentation for more information.
-
-Please report problems as issues.
-
-The Arduino SdFat library provides read/write access to FAT16/FAT32
-file systems on SD/SDHC flash cards.
-
-SdFat requires Arduino 1.6x or greater.
-
-To use SdFat, unzip the download file and place the SdFat folder
-into the libraries sub-folder in your main sketch folder.
-
-For more information see the Manual installation section of this guide:
+```
+ \Users\bill\Documents\Particle\projects\SdFatMod>ls *
+README.md  argon_firmware_1545324931631.bin  project.properties
 
-http://arduino.cc/en/Guide/Libraries 
+lib:
+SdFat
 
-A number of configuration options can be set by editing SdFatConfig.h
-define macros.  See the html documentation for details
+src:
+SdFatMod.ino
+```
 
-Read changes.txt if you have used previous releases of this library.
+The mods required changing the type for open flags from uint8_t to int so
+bugs are likely if any uint8_t local variables were missed.
 
-Please read the html documentation for this library.  Start with
-html/index.html and read the Main Page.  Next go to the Classes tab and
-read the documentation for the classes SdFat, SdFatEX, SdBaseFile,
-SdFile, File, StdioStream, ifstream, ofstream, and others.
- 
-Please continue by reading the html documentation.
