[hpsdr] Pennylane i2c address question

[wully]

Hi

After a lengthy pause, I try to use Magister again. The system consists 
of mercury, pennylane, excalibur and ozy.

When I try to write to i2c address to check the presence of the exciter 
with code:

nt i2c_address=0x1b; // penelope
unsigned char buf[3]={0x1e,0x00,0x00}; //    1E 00 - Reset chip (intern 
1111)
int errcode;
     errcode = Write_I2C(uhd,i2c_address , buf, 2);
     if (errcode<=0)
     {
         fprintf(stderr,"Penelope not present, no TLV-Init %i\n",errcode);
         return;
     }

I don't see pennylane, so I don't initialize TLV and so the microphone 
does not work.

Questions:
1) does pennylane have another i2c address?
2 which one?
3) Is the code not ok for pennylane?
