2020-12-06Rework hardware probing and RTL-SDR helper startupScott Murray1-0/+3
The lazy startup of the separate helper program for the RTL-SDR backend on playback start was incorrect with respect to the expected behavior the frequency setting verbs. This was not visible during usage by the radio application, but was triggering failures in several tests in the pyagl binding wrapper test suite. To facilitate starting the helper during backend initialization, the probing part of the backend "init" has been split into a separate "probe" function, and all backends have been updated to reflect this change. Logic has been added to enforce that "init" is only called after "probe" has succeeded for a backend, and a comment has been added to radio_impl.h to document this intended behavior.

2019-01-04Add audio role open/close supportScott Murray1-1/+3
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.

2018-07-17added api verb for RDS informationThierry Bultel1-0/+2
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>
2018-06-05Rework output to directly support 4Aflounder_5.99.1flounder/5.99.15.99.1Scott Murray1-1/+1
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.

2018-03-20Add Kingfisher Si4689 supportHarunobu Kurokawa1-16/+21
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.
