selber programmiert und getestet. ansonsten datenblatt lesen, lesen und
lesen. die haben da schon etwas eigenartige logik...
benutzte sdo und nicht nirq als statusabfrage. brauchst nur 4 leitungen
zum kommunizieren.
---grundeinstellungen(transmit/receive)---------------------------------
---------------------------------------
---3.Frequency Setting
aed8 f=ed8h, fo=10*C1(C2+ed8h/4000)=439,5MHz, C1=1, C2=43, Band
433Mhz(b in 1.Configuration Setting Command )
---4.Data Rate Command
c623 cs=0, r=22h, BR=10000/29/(r+1)/(1+cs*7)=9,6kbit
---5.Receiver Control Command
90c0 i=6h, Receiver baseband bandwidth (BW)=67kHz
g=0, LNA gain select=0dB
r=0, RSSI detector threshold=-103
---8.Synchron Pattern Command
ced4 b=d4, The Byte0 of the synchron pattern, kann zum adressieren
benutzt werden
---11.TX Configuration Control Command
9820 mp=0, m=2, fdev=(m+1)*15kHz=45kHz
p=0, Relative Output Power=0dB
---transmit-------------------------------------------------------------
-----------
8098 1. Configuration Setting
el=1 TX register is enabled
b=1 433MHz Band
x=8 Crystal Load Capacitance=12,5pF
8239 2. Power Management
et=1, Switches on the PLL, the power amplifier, and starts the
transmission (If TX register is enabled)
es=1, Turns on the synthesizer
ex=1, Turns on the crystal oscillator
dc=1, Disables the clock output (pin 8)
b82d Synchron Pattern byte 1
b8d4 Synchron Pattern byte 0

8219 2. Power Management
et=0, TX abschalten
es=1, Turns on the synthesizer
ex=1, Turns on the crystal oscillator
dc=1, Disables the clock output (pin 8)
8018 1. Configuration Setting
el=0, TX register is disabled(wenn wieder auf 1 dann wird fifo mit
aaaaH(preamble) gefüllt)
b=1, 433MHz Band
x=8, Crystal Load Capacitance=12,5pF
---receive--------------------------------------------------------------
----------
8058 1.Configuration Setting
ef=1, enables the FIFO mode
b=1, 433MHz Band
x=8, Crystal Load Capacitance=12,5pF
82d9 2.Power Management
er=1 Enables the whole receiver chain
ebb=1 The receiver baseband circuit can be separately switched on
es=1 Turns on the synthesizer
ex=1 Turns on the crystal oscillator
dc=1 Disables the clock output (pin 8)
---bemerkung ca80, ca82 ff=0 dann ff=1, restart the synchron pattern
recognition
ca80 7.FIFO and Reset Mode Command
f=8, FIFO IT level=8bit
sp=0, length of the synchron pattern=2
al=0, FIFO fill start condition=Synchron pattern
ff=0, The FIFO fill stop
ca82 7.FIFO and Reset Mode Command
f=8, FIFO IT level=8bit
sp=0, length of the synchron pattern=2
al=0, FIFO fill start condition=Synchron pattern
ff=1, FIFO fill will be enabled after synchron pattern reception
