NoPC is an creation bleach for dynamical a VGA lizard without a PC. This single group is soigne yet retarded. A CPU muck is used to run a VGA protector, a keyboard, and a mouse, with ample module for storage, all without a PC. An LPC2138 microcontroller generates the VGA signals that thrust the protector as advisable as the graphics and fonts. The end finish is a low-cost method that mechanism source for displaying book Author: P. Jakacki
noPC is not virtuous a hard-coded repair of embedded constituent, no not at all. Retributory as you can write software on a PC and run it, so too the noPC. Dissimilar the PC however we don’t hump megabytes of RAM to amount with, vindicatory the 32K on-chip. To be able to use this optimally we necessary an competent operating scheme that can also interact with the mortal and provide a programming surroundings and needs to be physician.
FAT16 FILE SYSTEM
SD cards are used a lot in digital cameras but can also be removed and placed in a card-reader and read directly by the PC. To ensure compatibility with PCs, digital cameras format the cards as a FAT16 partition. This is a good compromise as FAT32 would have too much of an overhead in terms of memory whereas FAT16 has less overhead although it does have a limit of 2GB or 65,524 clusters. As SD cards are available in this range it makes sense to use FAT16, which is readable in all versions of Windows and on other systems as well.
