Simple and easy? Start in assembly. Want a taste of it? 6 lines of code and you have 8 leds blinking as a binary counter. Just connect the 8 leds to all port B pins via 330-500 ohms resistors. out ddrb,255 ; set portb output a1: out portb,r16 ; move R16 to PortB inc r16 ; increme

Hi all, So much to do, so little time. Here is my latest project : It is an interface and temp monitor system come home automation. It will have 3 RS 232 ports, 1 for programming my PABX, 1 to log PABX calls and the last to interface to the FreeBSD server. It will also have about

I'm developing an interface between the E128 & Nordic's nice 2.4GHz chips. Nordic doesn't have a discussion group, suggesting I start one - so I have. If you are looking to use this chip, you might like to join to give it a kick along. There is a version that has an 8051 on-board
