NS73M fm radio trasmitter

[Boris]

Have somebody used this chip (from sparkfun.com)?
I'm trying to read the registers, but my firmware don't works.

Boris, Any luck on this? I will be moving into an NS73M from a BH1417.

The NS73M works without problem, but I could not read the registers. I can write them, so I can set the frequency and all parameter, but no read...

Not trying to cheat, but if you would not mind sending me a couple of lines of your sample code so I will have something to work with starting out I would appreciate it.

Reading the registers of the NS73M? I guess my first question is why? I am not sure what the advantage or use would be.

Cheers!

This is my code:

EEPROM 0,[3,232,0,0]    'FREQ.BYTE1 FREQ.BYTE0 PW SENS
READ 0,FREQ.BYTE1
READ 1,FREQ.BYTE0
READ 2,PW
READ 3,SENS

SETUP:

   REG=$0E:VAL=$05:GOSUB SCRIVI         ' Software reset
   REG=$01:VAL=$B4:GOSUB SCRIVI     ' Pilot on, forced subcarrier
   REG=$02:VAL=$07:GOSUB SCRIVI  ' 2 mW power, Unlock detect on  REG=$08:VAL=$1A:GOSUB SCRIVI     ' CEX = Band 2
   REG=$00:VAL=$A1:GOSUB SCRIVI     ' Pwr on, 200 mV audio for 100% modulation
  
   REG=$06:VAL=$1E:GOSUB SCRIVI' Set internal charge pumps
 




SCRIVI:
I2CWRITE DA,CK,%11001100,REG,[VAL]
RETURN

Boris,

Much Appreciated! Not sure if I can do anything about reading registers, I am just beginning. But I can get anything to work, I will post it here.

Cheers!
