The uM-FPU V3 Integrated Development Environment (IDE) software provides an easy-to-use tool for developing applications using the uM-FPU floating point coprocessor. The IDE runs on Windows 98, NT, ME, 2000 and XP, and provides support for:
- Generating uM-FPU code for math expressions
- Debugging uM-FPU code
- Storing user-defined functions on the uM-FPU chip
Generating uM-FPU V3 Code
The code generator is a type of application builder, or wizard, that takes standard math expressions and generates the required uM-FPU V3 code for a selected target. A number of targets are supported, including: Basic Stamp®, Javelin Stamp™, SX/B Compiler, PICAXE and PICmicro® assembler. Additional targets will be added - check the Micromega website for up-to-date information. The generated code can be easily copy and pasted into the user's microcontroller program in the target development environment. The examples shown in this document use the BASIC Stamp with an SPI interface. If you are working with a different microcontroller or compiler, the procedures are the same, but the output code and target development environment will be different.
Debugging uM-FPU V3 Code
The IDE uses the built-in debugger on the uM-FPU V3 to provide the user with valuable debugging information such as uM-FPU instruction traces, and register values, and allows the user to set breakpoints and step through the execution of uM-FPU instructions.
Storing User-Defined Functions
The IDE supports storing user-defined functions and setting parameters on the uM-FPU V3 chip. This unique capability can reduce the memory usage on the microcontroller, simplify the interface, and increase the speed of operations.
