We have board support packages (BSPs) and complete projects
available for various NEC Eval boards.
Different software packages are available for different
boards; the packages include some or all of the following components:
- embOS - real time OS / RTOS
- emWin - graphic software / GUI
- emFile - file system with support for NAND-, NOR- flashes, SD, CF
cards, IDE and more
- emUSB - USB device stack with support for bulk, MSD, CDC, HID and
more
Some packages are executable demos, which can not be modified; some packages are trial versions, which come with the software
in a library and the application in source code form, as well as a project
for the IDE that has been used. Trial versions can usually be recompiled
easily in less than a minute if the required compiler and IDE is installed.
The application program can be modified, allowing intensive tests of the
software. emWin trial versions usually also contain a simulation environment
which allows test and recompilation on a PC.
