Hallo,
ich wollte den RFM12 (an MBED NXP1768) mit der Betty ansteuern,
aber irgendwie krieg ich keine Kommunikation hin.
http://www.mikrocontroller.net/topic/194471 hat mir nicht geholfen, das rfm12 scheint nix zu empfangen ,obwohl ich data whitening ausgeschaltet und den RFM12 auf 19200 Baud gestellt hab.
Kann jemand der die Verbindung geschafft hat da helfen?
RFM12 CONF:
writeCmd(0x0000); // intitial SPI transfer added to avoid power-up problem
writeCmd(RF_SLEEP_MODE); // DC (disable clk pin), enable lbd
// wait until RFM12B is out of power-up reset, this takes several *seconds*
writeCmd(RF_TXREG_WRITE); // in case we're still in OOK mode
while (NIRQ == 0) writeCmd(0x0000);
//my init
writeCmd(0x80D7); //EL,EF,433band,11.5pF
writeCmd(0x82D9); //!er,!ebb,ET,ES,EX,!eb,!ew,DC
writeCmd(0xA514); //433,25 MHz
writeCmd(0xC611); //19.200 baud
// writeCmd(0xC647); //4.8kbps
writeCmd(0xC48C); //VDI,FAST,200kHz Bandbreite, -6dB Verstärkung, DRSSI threshold: -79dBm
// writeCmd(0x94A0); //VDI,FAST,134kHz,0dBm,-103dBm
writeCmd(0xC2AC); //AL,!ml,DIG,DQD4
writeCmd(0xCA81); //FIFO8,SYNC,!ff,DR
writeCmd(0xC483); //@PWR,NO RSTRIC,!st,!fi,OE,EN
writeCmd(0x9870); //!mp,120kHz,MAX OUT
// writeCmd(0x9850); //!mp,9810=30kHz,MAX OUT
writeCmd(0xE000); //
writeCmd(0xC800); //

writeCmd(0xCA81); //FIFO initialisieren
writeCmd(0xCA83); //FIFO aktivieren

}
wäre echt um hilfe froh.
wenn ich den menu eintrag aufrufe, erscheint das sendesymbol im display nicht, heißt das , das auch gar nichts gesendet wurde?
Danke,
Thomas
