I'd visit my favorite vendor, DigiKey, Mouser, Newark, etc, and see what is available in demo kits with USB. All the manuals and software are online for download from Atmel. Study them, see what your vendor stocks, and make a selection. Each demo board has an assortment of demo projects which will come up running pretty quickly. HID on USB should have multiple options to chose from. For example I'm currently using an ATxmega256A3BU X-plain board with USB and LCD and I forget what else. It was about $50. But I'm not using USB or LCD, I wanted DMA and AES. When/if the time comes to make my own board I'll go back to the Atmel matrix and select a CPU which meets my needs. But then again if this one is $8 and another is $7.50 I'll probably not change. -- David Kelly N4HHE, [email protected] ============================================================ Whom computers would destroy, they must first drive mad. _______________________________________________ AVR-chat mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/avr-chat
