2018-06-05Rework output to directly support 4Aflounder_5.99.1flounder/5.99.15.99.1Scott Murray9-57/+382
When building for 4A, switch to new gstreamer-based ALSA output for the RTL-SDR backend, and the Kingfisher backend now uses a gstreamer pipeline for its loopback to either an ALSA or Pulse sink depending on 4A or not. Using gstreamer instead of direct ALSA output has the benefit of transparently handling resampling to the M3ULCB hardware's required 48 KHz sample rate for the RTL-SDR backend.

2018-06-05Split rtlsdr code into standalone helperScott Murray6-60/+487
To avoid the GPL licensed code in rtl_fm.c making all of the binding GPL, rework things to wrap it with a simple standalone helper executable that is driven via stdin/stdout. While this could potentially be done by running the original unmodified rtl_fm utility itself, it would be impossible to implement scanning with that approach without some compromising of playback latency and quality. The current helper implementation is simple enough that replacing it with an alternate one should be relatively straightforward if that is desired.

2018-06-05Always enable Kingfisher supportScott Murray3-12/+10
Make Kingfisher support unconditional to move all platform detection to run-time. This fixes the issue of violating the application build workflow with the SDK. Additionally, the Kingfisher detection has been improved with an added check for the Si4689 device-tree node to differentiate from a regular M3ULCB, and the Kingfisher output has been fixed for recent BSP changes.

2018-03-20binding: update kingfisher i2c bus numberHarunobu Kurokawa1-4/+4
The Si4689 radio chip I2C bus number has shifted from i2c-11 to i2c-12. This updates I2C bus number in SI scripts accordingly. Signed-off-by: Harunobu Kurokawa <harunobu.kurokawa.dn@renesas.com>
2018-03-20Add Kingfisher Si4689 supportHarunobu Kurokawa8-62/+632
Add conditionally compilable support for the Si4689 radio on the M3ULCB Kingfisher infotainment board. The codebase has been refactored to allow multiple radio implementations, and when Kingfisher support is enabled, the binding will first look for a USB RTL-SDR adapter, then fallback to the Kingfisher Si4689 if one is not found. This allows easily switching to a RTL-SDR adapter if this initial Kingfisher support encounters issues. The back end implementation relies on a patched version of the "si_ctl" utility from Cogent Embedded's Kingfisher BSP changes. The modifications to it add FM band plan selection and scanning threshold tweaking for poor radio environments. Audio output is achieved by looping the radio's PulseAudio source to the appropriate sink depending on 4A or non-4A operation. For 4A compatibility, the PulseAudio source is created if it does not exist, which currently is the case due to PulseAudio's udev module being disabled when 4A is enabled. Additionally, the FM band plan for Japan has been corrected to go to 95 MHz, and a README.md file has been added documenting the optional configuration that can be done via /etc/xdg/AGL.conf for band plan selection and scanning sensitivity.

2017-10-11Switch to AFB_SESSION_NONE for verbsScott Murray1-12/+12
Recent testing found that the verbs no longer work now with the AFB_SESSION_CHECK flag set on them and the binding split out to be standalone from the app. Since the radio does not really need the concept of a session, switch to AFB_SESSION_NONE to get things working, rather than add the extra infrastructure to enable session support.

2017-05-23Rework to add and use a binding for radio controlScott Murray12-0/+2949
A radio binding has been added in the new binding directory, and the application has been reworked to use it. The binding uses a modified version of the rtl_fm code used in the qtmultimedia radio plugin that was previously used, and some new code has been added to output to PulseAudio using the asynchronous API to ensure compatibility with stream corking. The rtl_fm code has been enhanced to add seeking support, and the application has been tweaked to use it.
