Some of these reasons * are: * * - Portability: * The LUFA stack is designed to run (at some capacity) on the entire Atmel range of USB AVRs, regardless of the * exact USB controller revision used. If you decide to implement your own USB stack, you will either need to * code around the differences between each USB AVR controller's implementation between different chip models, or * require your code to run on only one specific USB AVR model series. * * - Speed of Development: * LUFA ships with a wide range of pre-made demos, bootloaders and projects for you to try, learn and extend. Each * of these demos are tested (where possible) across as many USB AVRs and Operating Systems as possible, to ensure * that they work under as many conditions as possible. In addition, there are inbuilt class drivers for several of * the USB classes which you can make use of in your projects with minimal effort. * * - Maintainability: * As LUFA takes care of much of the USB implementation, you can be left to focusing on your actual project's * functionality, rather than being held back developing and debugging the USB stack code. Since LUFA uses clear APIs * for USB development, your code will be more readable than if it had the low level USB stack code integrated into * it directly. Updating the LUFA library is a simple folder-replacement and gives new features and bug fixes in * seconds each time a new release is made. * * - Size: * Not just requiring less code to make complex USB devices, LUFA (under most cases with the correct compile options) * requires less FLASH space than Atmel's stack, meaning more space for the user application*. * * - Support: * Since many people are now using LUFA in their own projects, you can take advantage of other's knowledge when you run * into difficulties or need some advice. In addition, you can also email the library author to receive personalized * support when you need it (subject to author's schedule). * * * Atmel Stack Mouse Device Demo 4218 bytes, LUFA Mouse Low Level Device Demo 3526 bytes, under identical build * environments */
