I compiled the Si4703_Radio_Test example, to get first steps with my new breakout.
But I cannot get it working. Seeking up and down the frequency stays always 875 (87.5 MHz).
I dived a little bit deeper and found that the seek function returns get_channel().
get_channel itself performs readRegisters() and returns (si4703_registers[READCHAN] & 0x03FF)+875, which explains the value.
I wrote a little debug helper, that showed me, that the 16 registervalues are always:
0x1242, 0x1200, 0x4401, 0x0, 0x3800, 0x10, 0x0, 0x8100, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x0
The only change in this values I see, when changing the volume, in this case si4703_registers[SYSCONFIG2] changes its value.
