[hpsdr] I2C codes

[Phil Harman]

Hi Alberto,

There are some explanations in initozy11.bat  i.e. 

rem        1E 00 - Reset chip
rem        12 01 - set digital interface active
rem        08 15 - D/A on, mic input, mic 20dB boost
rem        08 14 - ditto but no mic boost
rem        0C 00 - All chip power on
rem        0E 02 - Slave, 16 bit, I2S
rem        10 00 - 48k, Normal mode
rem        0A 00 - turn D/A mute off

rem the following are for Janus 
writeI2C 0xfffe 0x7 0x1a  0x2  0x1e 0x00
writeI2C 0xfffe 0x7 0x1a  0x2  0x12 0x01
writeI2C 0xfffe 0x7 0x1a  0x2  0x08 0x15
writeI2C 0xfffe 0x7 0x1a  0x2  0x0c 0x00
writeI2C 0xfffe 0x7 0x1a  0x2  0x0e 0x02
writeI2C 0xfffe 0x7 0x1a  0x2  0x10 0x00
writeI2C 0xfffe 0x7 0x1a  0x2  0x0a 0x00
rem

rem the following are for penny
writeI2C 0xfffe 0x7 0x1b  0x2  0x1e 0x00
writeI2C 0xfffe 0x7 0x1b  0x2  0x12 0x01
writeI2C 0xfffe 0x7 0x1b  0x2  0x08 0x15
writeI2C 0xfffe 0x7 0x1b  0x2  0x0c 0x00
writeI2C 0xfffe 0x7 0x1b  0x2  0x0e 0x02
writeI2C 0xfffe 0x7 0x1b  0x2  0x10 0x00
writeI2C 0xfffe 0x7 0x1b  0x2  0x0a 0x00
rem pause

Then please see the TLV320AIC23B datasheet.

  Where can I find a detailed explanation of the various codes that are sent to the Mercury/Janus/Penelope cards
  with the writeI2C utility, as used in the initozy.bat ?

  Like, e.g.   (I suppose 0x1a is Mercury ? Or is it Janus ?)

  writeI2C 0xfffe 0x7 0x1a  0x2  0x1e 0x00
  writeI2C 0xfffe 0x7 0x1a  0x2  0x12 0x01
  writeI2C 0xfffe 0x7 0x1a  0x2  0x08 0x15
  writeI2C 0xfffe 0x7 0x1a  0x2  0x0c 0x00
  writeI2C 0xfffe 0x7 0x1a  0x2  0x0e 0x02
  writeI2C 0xfffe 0x7 0x1a  0x2  0x10 0x00
  writeI2C 0xfffe 0x7 0x1a  0x2  0x0a 0x00

  Thanks
