Hi! I'm currently programming PWM (pulse width modulation) on an ATMega 128 in a tinyOS-environment. Programming of PWM is ready, but now I wanted to remote control one Mote with the PWM by another, which is connected to a programming board.
So I used TOSBASE and SimpleCmd for basic and put my PWM code in the command-process of SimpleCmd. The TOSBase-Mote is then administrated by programming board using UART and it sends commands via RadioCRCPacket to SimpleCommand, which receives them by GenericComm. The remote control works fine, I checked by LEDs. To realize PWM, I used register DDRB of ATMega 128 to set output-Pins. But when any bit of this register is set to 1, no Radio-Packets will be received anymore. Code like outp(0x20, DDRB) (in tinyOS 1.1.0) and manually set bits by sbi() and cbi() (in tinyOS 1.1.11) results the same curious effect. How does GenericComm or RadioCRCPacket use DDRB-register and how can I use PWM-ports without getting every Radio-Connection crashed. Many thanks, BiBe _______________________________________________ Tinyos-help mailing list Tinyos-help@Millennium.Berkeley.EDU https://mail.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
