From: travisutk Date: Sun, 19 Dec 2010 00:52:54 +0000 (+0000) Subject: Added 'goodfet.cc sniffdash7'. X-Git-Url: http://git.rot13.org/?p=goodfet;a=commitdiff_plain;h=1f2a8a4593c69edd03f774a2df080103814faeae Added 'goodfet.cc sniffdash7'. Utterly untested, as I haven't got Dash7 hardware. Register settings came from the unreleased OpenTag/CC430 port, might or might not be accurate. git-svn-id: https://svn.code.sf.net/p/goodfet/code/trunk@791 12e2690d-a6be-4b82-a7b7-67c4a43b65c8 --- diff --git a/client/GoodFETCC.py b/client/GoodFETCC.py index 9397201..3be0ca4 100644 --- a/client/GoodFETCC.py +++ b/client/GoodFETCC.py @@ -211,7 +211,76 @@ class GoodFETCC(GoodFET): RFST=0xDFE1 self.pokebyte(RFST,state); #Return to idle state. return; + def config_dash7(self,band="lf"): + #These settings came from the OpenTag project's GIT repo on 18 Dec, 2010. + #Waiting for official confirmation of the accuracy. + + self.pokebysym("FSCTRL1" , 0x08) # Frequency synthesizer control. + self.pokebysym("FSCTRL0" , 0x00) # Frequency synthesizer control. + + #Don't change these while the radio is active. + self.pokebysym("FSCAL3" , 0xEA) # Frequency synthesizer calibration. + self.pokebysym("FSCAL2" , 0x2A) # Frequency synthesizer calibration. + self.pokebysym("FSCAL1" , 0x00) # Frequency synthesizer calibration. + self.pokebysym("FSCAL0" , 0x1F) # Frequency synthesizer calibration. + + if band=="ismeu" or band=="eu": + print "There is no official eu band for dash7." + self.pokebysym("FREQ2" , 0x21) # Frequency control word, high byte. + self.pokebysym("FREQ1" , 0x71) # Frequency control word, middle byte. + self.pokebysym("FREQ0" , 0x7a) # Frequency control word, low byte. + elif band=="ismus" or band=="us": + print "There is no official us band for dash7." + self.pokebysym("FREQ2" , 0x22) # Frequency control word, high byte. + self.pokebysym("FREQ1" , 0xB1) # Frequency control word, middle byte. + self.pokebysym("FREQ0" , 0x3B) # Frequency control word, low byte. + elif band=="ismlf" or band=="lf": + # 433.9198 MHz, same as Simpliciti. + self.pokebysym("FREQ2" , 0x10) # Frequency control word, high byte. + self.pokebysym("FREQ1" , 0xB0) # Frequency control word, middle byte. + self.pokebysym("FREQ0" , 0x71) # Frequency control word, low byte. + elif band=="none": + pass; + else: + #Got a frequency, not a band. + self.RF_setfreq(eval(band)); + self.pokebysym("MDMCFG4" , 0x8B) # 62.5 kbps w/ 200 kHz filter + self.pokebysym("MDMCFG3" , 0x3B) + self.pokebysym("MDMCFG2" , 0x11) + self.pokebysym("MDMCFG1" , 0x02) + self.pokebysym("MDMCFG0" , 0x53) + self.pokebysym("CHANNR" , 0x00) # Channel zero. + self.pokebysym("DEVIATN" , 0x50) # 50 kHz deviation + self.pokebysym("FREND1" , 0xB6) # Front end RX configuration. + self.pokebysym("FREND0" , 0x10) # Front end RX configuration. + self.pokebysym("MCSM2" , 0x1E) + self.pokebysym("MCSM1" , 0x3F) + self.pokebysym("MCSM0" , 0x30) + self.pokebysym("FOCCFG" , 0x1D) # Frequency Offset Compensation Configuration. + self.pokebysym("BSCFG" , 0x1E) # 6.25% data error rate + + self.pokebysym("AGCCTRL2" , 0xC7) # AGC control. + self.pokebysym("AGCCTRL1" , 0x00) # AGC control. + self.pokebysym("AGCCTRL0" , 0xB2) # AGC control. + + self.pokebysym("TEST2" , 0x81) # Various test settings. + self.pokebysym("TEST1" , 0x35) # Various test settings. + self.pokebysym("TEST0" , 0x09) # Various test settings. + self.pokebysym("PA_TABLE0", 0xc0) # Max output power. + self.pokebysym("PKTCTRL1" , 0x04) # Packet automation control, w/ lqi + #self.pokebysym("PKTCTRL1" , 0x00) # Packet automation control. w/o lqi + self.pokebysym("PKTCTRL0" , 0x05) # Packet automation control, w/ checksum. + #self.pokebysym("PKTCTRL0" , 0x00) # Packet automation control, w/o checksum, fixed length + self.pokebysym("ADDR" , 0x01) # Device address. + self.pokebysym("PKTLEN" , 0xFF) # Packet length. + + + + + self.pokebysym("SYNC1",0xD3); + self.pokebysym("SYNC0",0x91); + return; def config_simpliciti(self,band="none"): self.pokebysym("FSCTRL1" , 0x0C) #08 # Frequency synthesizer control. self.pokebysym("FSCTRL0" , 0x00) # Frequency synthesizer control. diff --git a/client/goodfet.cc b/client/goodfet.cc index a7a0494..3b3ade4 100755 --- a/client/goodfet.cc +++ b/client/goodfet.cc @@ -128,6 +128,8 @@ if(len(sys.argv)==1): print "%s carrier [freq]\n\tHolds a carrier on [freq] Hz." % sys.argv[0]; print "%s reflex [freq]\n\tJams on [freq] Hz." % sys.argv[0]; print "%s sniffsimpliciti [us|eu|lf]\n\tSniffs SimpliciTI packets." % sys.argv[0]; + print "%s sniffdash7 [lf]\n\tSniffs Dash7.
