Date: Sun, 13 May 2007 16:30:58 -0800 Some progress has been achieved. I can now barely make out a faint channel when I set the gain for line1 in to max. Tuning to a station in OF will stay tuned if you turn the player on to rockbox right away. I have tried adjusting every single volume related register, but was not able to make it louder. The LCD screen creates a heavy buzz when it is on, but when it turns off there is no problem (the gain is the issue here). I have uploaded some test code here: http://www.iwdstudio.com/rockbox/rock.zip Obviously not up to coding standards and such, but it will give people an idea how to read/write from the tuner. I can verify that all the read register function are correct. However, write may not (but I can't verify it). The datasheet for the tuner: http://www.rockbox.org/twiki/pub/Main/DataSheets/AN2400S04.pdf Is quite ambiguous in some sections, and sometimes contradicts the register sheet: http://www.semiconductor-sanyo.com/ds_e/ENA0070.pdf If you read the tuning part, you will see why there is a bunch of pseudocode in the file above, as I could not understand parts of it. That's what I have so far. Ivan Received on 2007-05-14 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
