Changes for GEMstudio version 1.3.0.0

New Features:    

• Low Power SDRAM modes added
• Low Power Sleep modes added
• Amulet:Calendar object and Real Time Timer added

Bug Fixes:

• Fixed bug regarding invisible imageBar widgets with a non-zero value for min. When sent the reappear() method it would cause problems.
• InternalRAM RPC messages sent using the CRC protocol were missing the CRC at the end of the message.
• Watchdog would reset if uploading a large image primitive
• Multiple hrefs with InternalRAM variables now work as expected. InternalRAM variables can be modified in a previous function call and you can now use that InternalRAM variable in a later function call. (i.e. Amulet:InternalRAM.byte(0).add(2).Amulet:InternalRAM.string(InternalRAM.byte(0)).setValue('fixed') will now use the correct value for InternalRAM.byte(0) as the argument in the second function. In previous GEMstudio versions it was required to split up the multiple functions into separate META tags, which added to the code space used and made it harder to follow.
• If only one image on a page was cached, it didn't really get cached in version 1.2.1.
• Amulet:math.randomByte.maskedValue(x), Amulet:math.randomFilteredByte.value(), and Amulet:math.randomFilteredByte.maskedValue(x) all correctly supported.
• The OS fonts took up twice as much serial data flash space as they were supposed to.
• GEMstudio layout now correctly shows a line feed when \n entered in the label of a button. It looked correctly in the GEMplayer or in the actual module, but the WYSIWYG showed the literal \n.
• Fixed bug in List Box Widget regarding a forceUpdate() being called on a list box and the new list choice was higher up the list than the current selection. The list did not scroll itself up to show the new list choice.
• Fixed bug in List Box Widget regarding attempting to read the current value of a list box that did not have any choice selected. GEMplayer would crash and the actual module would have indeterminate effects.
• Fixed bug when attempting to disappear an already disappeared object that had just moved. When the second disappear was called, the background where the object was prior to the move would then show up in the rectangular region where the object had been moved to.
• fromInitHref(x), where x is the precision, is now supported by Function and Custom Buttons within GEMstudio.
• Fixed bug when a multi href object and a sequenced href object were on the same page and with the same signature. If one was separated by commas and the other by semi-colons, but the functions were the same, only the first object would be created, but erroneously used in both cases.
• GEMplayer's 10ms timer is much more accurate.
• Fixed bug in static text layout. Formatting would only be correct when first entered. Upon reloading a saved .gemp file, all static text formatting would be lost.
• When entering color names as an argument, it was required to use single quotes. Now single or double quotes can be used.
• If Slider Widget's optional orientation attribute is set such that the the handle travels along the shorter axis, the GEMstudio WYSIWYG layout pane will now draw the slider correctly.

Enhancements:

• Visual objects in GEMstudio layout mode can be resized while keeping the same aspect ratio by holding the shift key down while dragging one of the four corners of the object.
• Added BMP, TIFF and PICT image support within GEMstudio.
• Hardware related attributes (i.e. flash size, SDRAM size, etc...) are now stored in Board Profiles which are separate from LCD Profiles.
• Auto-complete added to the Page Function editor.
• Find and replace added to the Page Function editor.
• Keyword highlighting added to the Href and Page Function editors.
• C-style comments supported in both the Href and Page Function editors.
• Page Functions editor remembers the cursor position and folded lines between sessions.
• Macro and InitInternalRAM now supported within the GEMstudio GUI.
• Slider and List Box widgets now can use the argument "intrinsicValue" to specify the argument to use is the current intrinsic value of the widget. In earlier versions the argument was left blank to specify to use the intrinsic value.
• SDRAM starts out in "low power" mode, saving approximately 15mA. SDRAM can be set back to high performance mode through Amulet:lowPower.sdram(HIGH_PERFORMANCE).
• Greatly improved dual frame buffer performance. Most noticable when dealing with Custom Slider widgets that have a handle image with transparency.
• All view widgets can now send their current values out via Inter Widget Communication if requested.
• ImageSequence Widgets can now use cached images.
• ImageSequence image chooser allows user to add multiple images at one time instead of only a single image at a time.
• Background images now have the noSDRAM attribute set to TRUE by default if the image is full screen.
• hrefOnHitOnly added to both the Custom Slider and List Widgets.

Changes for GEMstudio version 1.2.1.0

New Features:    

• Added Run button from GEMcompiler, allowing for direct access to the GEMplayer for any HTML based project. Only valid on 30-day trials and full versions of the GEMstudio. After the 30-day trial has expired, the GEMcompiler will still work, but the access to the GEMplayer is disabled.

Bug Fixes:    

• Fixed bug in UART programming. Watchdog timer was erroneously resetting the processor five seconds into programming the flash.
• Fixed bug in "get byte array" and "get word array" in ASCII communications protocol. After adding the CRC protocol, these two opcodes were erroneously removed from the ASCII protocol.
• Fixed hole in 8-bit color depth and .gifs with a transparent color. If the .gif palette and the Amulet were not exactly the same, there was a chance the transparent color would not be interpreted correctly.
• Fixed bug in button label wrapping within GEMstudio WYSIWYG edit mode.
• Newly created projects now appear in the list of last opened files.
• Added a negative number sanity check to keep slider handles from "teleporting" from the minimum location to the maximum location if the touchpanel is touched in the far left section on a horizontal slider or touched in the farthest bottom section on a vertical slider.

Enhancements:  

• GEMstudio can now handle multiple plots and graphs.
• Added a new OS page that says "Loading..." upon powering up, during the stage where the OS and any cached images are loaded in the SDRAM.
• Custom Button images can now be cached.
• Added the ability to disable the watchdog timer. The attribute is tpWatchdogEnable in the touch panel .ini file found in the Global/Configuration/TouchPanel folder.

Changes for GEMstudio version 1.2.0.0

New Features:    

• Added new CRC Communication Protocol, which is now the default Amulet serial protocol.
• Added ability to save and open Amulet Production files (.pdb and .gem). When saving to Amulet Production files, the current OS is always stored with the project automatically, thus preventing any issues of a project being loaded into a module with an incompatible OS.
• The GEMcompiler can now be launched right from the main GEMstudio page. Even after the 30-day trial has expired, the launching of the GEMcompiler is still available.

Bug Fixes:    

• Fixed bug in "set word array" in communications protocol. Was only setting the LSB prior to this release.
• While in GEMstudio, Project > Set To Home Page is now grayed out while current home page is highlighted. Used to cause an exception and closed the program if selected while on current home page.
• List widget Options strings can now have spaces in them.
• List widget initHref parameter now works correctly.
• GEMstudio now throws an error if an imageSequence widget contains no images.
• Slider widgets can now use a hex number for the initialCondition.
• When trying to program a project while Amulet module is in Program Mode, GEMstudio will give the correct error message telling the user to program the project while in Run Mode. Only Amulet OS files are allowed to be programmed while in Program Mode.
• Fixed bug in Image Bar widget when the min attribute was a non-zero value. Caused GEMplayer to crash and the Amulet OS to display garbage.
• HTML escapes (i.e.  ) are now supported in stringField widget's printf attribute.
• The InternalRAM String method appendChar('y') now supports all characters, including UTF-8 multi-byte characters.
• Fixed bug in imageSequence if the image changes while imageSequence was currently invisible and then set to reappear(). Garbage would be displayed instead of the correct image.
• Added ability to change the Java Max Heap Size. On certain machines, the default size of 512MB would cause GEMstudio to crash immediately upon booting.

Enhancements:  

• Added the InternalRAM String methods: appendString("y"), appendToRamString(x), appendViaByteVarPtr(x).
• Can now Run or Program a page that does not have any objects on the canvas.
• Hex numbers that are entered into GEMstudio stay hex numbers rather than automagically being converted to decimal.
• 30-day trial version can now program up to 5 GEMstudio pages, instead of only 1.
• This change log can now be accessed from within GEMstudio using Help > View Change Log.

Changes for GEMstudio version 1.0.3.1

Bug Fixes:    

• Fixed bug in slave communications if display uses SPI for initialization. Resulted in no response from the Amulet.
• Custom arrow images for the List widget can now be used.
• GEMplayer now handles initialized InternalRAM variables correctly.

Enhancements:   

• GEMstudio projects can now be edited while help windows are open. (Help windows launched from the href editor or page functions window are still modal, meaning they must be closed before editing within GEMstudio.)
• Background images that have no transparency default to having cachedImage set to True.

Changes for GEMstudio version 1.0.3.0

Bug Fixes:    

• Fixed bug in the communications protocol when two masters sent a command at the same time. Error was with the way the Amulet handled the incoming master message. It responded fine, but it erroneously would resend its own master message again immediately rather than waiting for the timeout period.
• Fixed bug in dual master protocol when the Amulet received a page change command via serial protocol and while on the new page the Amulet received an unsolicited response to a master message (prior to sending any master messages out), the Amulet would either send out erroneous data or potentially even lock up as far as the serial communication is concerned.
• Fixed bug with Radio Buttons and Check Boxes if they are located on a page such that they are the 256th object or greater on the page.
• Amulet now responds to external master messages on the same communication port as the incoming master message. Prior to this release, the Amulet always responded on the Communication UART regardless of which port it received the master message.
• GEMstudio now gives a proper error message if attempting to reprogram an OS file if the serial data flash on the module is different than the size specified in the LCD Configuration menu.
• Custom Button widgets now default to a clear border instead of a black one.
• Function Button widgets now handle initHref correctly.
• Function Button now handles horizontal and vertical label alignment.
• Fixed SDRAM allocation issue with numericField widgets. Could have resulted in corrupted images in the next widget located in SDRAM as well as visual anomalies in the numericField.
• Fixed potential problem with multiple THEN statements within an IF..THEN..ELSE meta tag. Indeterminate behavior could be exhibited depending upon how many THEN statements and how often the page is compiled.
• Fixed bug in the SDRAM configuration dialog box. The changes entered did not always get saved correctly.

Enhancements:   

• The file formerly known as the .map file is now referred to as the .inc file. The new and improved .map file contains all the memory usage (both SDRAM and Serial Data Flash) for each object and each page of the project. Both the .map and .inc files are now located in the Map subfolder of the root project folder.
• Added the ability to change the touch priority when dealing with layered objects. By default, as far as touch priority goes, the objects that are on a visually higher layer have priority over objects on a visually lower layer. Meaning if you touch an area that has two touchable objects, the object that is visually lower actually takes control of the touch. If it is desired to use the opposite touch priority, use the "From Bottom To Top" selection in the Touch Priority option found in either the Page or Project Options menu.
• AlphaColor can be used on Function and Custom Buttons as a visual notification of being pressed. Choices for OnButtonPress are now: Alpha and Depress.
• 32-bit or 8-bit color depth can be specified within the LCD Configuration dialog box. By default, GEMstudio will use the AmuletDefault.pal Web-Safe palette if 8-bit color depth is chosen.
• PWM widget now has a new initialState option. Along with On and Off, No Change has been added, so a PWM widget can be added to a page without affecting a currently running PWM widget.
• Image Sequence Widget can now handle more than 256 images. Prior to this release the Image Sequence was limited to 256 images.
• Radio Buttons and Check Boxes can now use cached images to help speed up page transitions.
• noSDRAM parameter added to Check Box, Custom Button, Function Button and Radio Button. Allows ability to save SDRAM and potentially speed up page transitions, although each widget loses certain abilities if SDRAM is not used. The default state is to use SDRAM on all widgets.
• In many objects that contained images with transparency, it was required for the user to specify that the image had transparency. GEMstudio now internally sets the transparency flag if the image in question has any transparency properties without any action required by the developer.
• SDRAM and Serial Data Flash Size now specified in the LCD Configuration.
