fd. Object

This is the flash disk (fd) object; it allows you to use your device's flash memory for data storage. There are two methods of working with the flash memory:

Both methods can be used concurrently and complement each other whenever necessary.

Here is what the fd. object has to offer in terms of file-based access:

A warning note icon.On the advice of one of our customers, we would like to remind you that, like all other flash memory devices on the market, the flash ICs used in Tibbo devices allow for a limited number of write cycles. As the Wikipedia article on flash memory explains, modern flash ICs still suffer from comparatively low write endurance. In Tibbo devices, this endurance is around 100,000 write cycles per sector.

When you are using the flash memory for file storage, the fd. object employs sector wear leveling to maximize the life of the flash IC (but the life still remains limited). If your application employs direct sector access, then it is your job to plan the application around the life limitations of the flash memory. For data that changes often, consider using the EEPROM accessible through the stor. object. EEPROMs have much better endurance.
