New Features in Release 2.0 Beta

User-defined code generation
Target description files can now be defined to customize the IDE code generation by defining the code generation parameters. Target description files are text files, and can be modified with any text editor. Target description files that are stored in the ~Application Data\Micromega\Targets folder, will be read automatically each time the IDE is started. The Tools/Add Target File... and Tools/Add Target Folder... commands can be used to copy target files to the Targets folder. See documentation and sample files below. To use this feature with the new IDE, do the following:
  • Download a target description file or create a new one.
  • Use the Tools/Add Target File... or Tools/Add Target Folder... command to copy target files to the Targets folder.
  • The new targets will appear in the Target pop-up menu in the Input window
String display window
The debug window now displays the contents of the uM-FPU string buffer. It updates at the same time as the debug register display. The current status byte is also displayed.

32-bit Converter Tool
A 32-bit numeric conversion tool has been added to the Tools menu. It converts between, floating point, decimal, and hexadeciaml values. The hex values can be 8-bit, 16-bit, or 32-bit values.

Auto Step and Conditional Breakpoints (beta 6)
The Auto Step feature provides a means to automatically single step through FPU instructions. This feature, in conjunction with Auto Step Conditions, can be used to implement conditional breakpoints.

Find and Replace (beta 6)
Find and Replace capabilities have been added to the source window.

EEPROM Memory Map (beta 6)
The EEPROM Memory Map dialog displays the contents of EEPROM.
