ATNGW100 (cheap), and . AT91SAM9260-EK (expensive) Next step: . set up development platform . simple test with spi and shift registers Regards, /Karl ----------------------------------------------------------------------- Karl Hammar Aspö Data karl@xxxxxxxxxxx Lilla Aspö 148 Networks S-742 94 Östhammar +46 173 140 57 Computers Sweden +46 70 511 97 84 Consulting -----------------------------------------------------------------------
