2019-01-04Add audio role open/close supportScott Murray1-41/+6
Rework things so that the 4A audio role is only opened while playing, and closed when stopped. Further work will need to be done to handle the possibility of the output device changing on subsequent opens, both the RTL SDR and Kingfisher case have complications around doing so: - The RTL SDR helper application needs to be enhanced to add an output setting command. Killing it and starting it again would also work, but likely will add noticeable UI latency. - On the Kingfisher, the binding currently has no control over the output used for the loopback, as it is being set up down in the soft-mixer based on HAL values.

2018-07-17fixed the support for 4a frameworkThierry Bultel1-43/+91
Changed the api call for getting an audio role. Mapped the stop/start operations to mute/unmute actions on role verb. No longer uses a gstreamer pipeline for the sound output, since it is 4a-softmixer that performs the read/write loop instead.

2018-07-17added api verb for RDS informationThierry Bultel1-1/+39
Added a verb to retrieve the RDS information. Notice that it is only supported on the kingfisher implementation. Change-Id: I0e2a830ff77154eb8cbb780bb599fb49f71a5b1c Signed-off-by: Thierry Bultel <thierry.bultel@iot.bzh>
2018-07-17Set the binding version in cmake instead of sourceThierry Bultel1-1/+0
Setting AFB_BINDING_VERSION is cmake makes merges easier between branches, since it is always defined once at a single place instead that in each file that need it. Also removed the "INSTALL" section with LIBRARY_DESTINATION since it is now treated in app-templates.

2018-07-17Fixed compilation warningsThierry Bultel1-2/+0
Fixed all the compilation warning that appeared with the latest version of gcc. There are still warnings in the gstreamer headers, that would likely be fixed by a gstreamer bump. Change-Id: I3ae7698dbff47303be366d9755a643a013bb4e51 Signed-off-by: Thierry Bultel <thierry.bultel@iot.bzh>
2018-06-05Rework output to directly support 4Aflounder_5.99.1flounder/5.99.15.99.1Scott Murray1-46/+69
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.

2018-06-05Always enable Kingfisher supportScott Murray1-4/+9
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 Kurokawa1-0/+396
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.
