Improve radio RDS driver and framework

2017-02-12T03:19:32+00:00

* Remove unused bits like the radio event and simplify basic
radio interface. It can be more self-contained with rds.h only
required by radio and tuner code.

* Add post-processing to text a-la Silicon Labs AN243. The chip's
error correction can only do so much; additional checks are highly
recommended. Simply testing for two identical messages in a row
is extremely effective and I've never seen corrupted text since
doing that, even with mediocre reception.

Groups segments must arrive in order, not randomly; logic change
only accepts them in order, starting at 0.

Time readout was made a bit better but really we'd need to use
verbose mode and ensure that no errors were seen during receiving
of time and more checks would be need to have a stable PI. The
text is the important bit anyway.

* Time out of stale text.

* Text is no longer updated until a complete group has been
received, as is specified in the standard. Perhaps go back to
scrolling text lines in the radio screen?

* Add proper character conversion to UTF-8. Only the default G0
table for the moment. The other two could be added in.

* Add variants "RDS_CFG_PROCESS" and "RDS_CFG_PUSH" to allow
the option for processed RDS data to be pushed to the driver and
still do proper post-processing (only text conversion for now for
the latter).

action.c must desist in calling set_cpu_frequency from a tick

2017-01-21T17:03:23+00:00

The function is neither reentrant nor ISR callable. Instead of
using a ticked-based timeout, have the button driver provide the
unboost after a delay when waiting for a button.

HAVE_GUI_BOOST gets immediate boost after dequeuing any message,
otherwise the queue has to have at least three messages waiting
for it to trigger a boost-- essentially the behavior that existed
but now combined in one place.

Reenable database ramcache and playlist dircache

2017-01-17T20:27:47+00:00

Playlist dircache references should be back in working order.

Reenabling dircache references in the database ramcache is not
yet done as it requires quite a bit of rework. Otherwise, the
database in RAM is functional again.

Some buffer compatibility changes have been made for database
commit because the dircache buffer can no longer be stolen, only
freed by an API call.

Introduce new USB driver for Synopsys DesignWare USB OTG core.

2016-08-02T02:57:49+00:00

Based on g#844 and g#949, it is intended as a replacement for the
current s3c6400x USB driver.

The DesignWare USB OTG core is integrated into many SoC's, however
HW core version and capabilities (mainly DMA mode, Tx FIFO mode,
FIFO size and number of available IN/OUT endpoins) may differ:

CPU       targets        HW ver  DMA  NPTX FIFO  FIFO sz  #IN/OUT
--------  -------------  ------  ---  ---------  -------  -------
as3525v2  sansaclipplus  2.60a   Yes  Dedicated  0x535    4/4
          sansaclipv2
          sansaclipzip
          sansafuzev2
s5l8701   ipodnano2g     2.20a   Yes  Shared     0x500    4/5
s5l8702   ipod6g         2.60a   Yes  Dedicated  0x820    7/7
          ipodnano3g
s5l8720   ipodnano4g     ?       ?    ?          ?        ?

Functionality supported by this driver:
- Device mode, compatible with USB 1.1/2.0 hosts.
- Shared FIFO (USB_DW_SHARED_FIFO) or dedicated FIFOs.
- No DMA (USB_DW_ARCH_SLAVE) or internal DMA mode.
- Concurrent transfers: control, bulk (usb_storage, usb_serial) and
  interrupt (usb_hid).

Actually this driver is not used by any CPU, it will be enabled for
each individual CPU/target in next patches.

Replace SAMSUNG_YH920_PAD with YH92X

2016-01-25T08:23:09+00:00

seems more logical to me, and is more consistent, since
"SAMSUNG_YH92X_PAD" is already used in the tex files.

Get rid of USE_ROCKBOX_USB

2015-01-08T15:07:12+00:00

Except for unfinished or experimental ports, it isthe case that
USE_ROCKBOX_USB and HAVE_USBSTACK are both defined or both undefined.
Furthermore, it is a leftover of some early developments on the USB stack and
doesn't make sense anymore.

Introducing Targets iBasso DX50 & iBasso DX90

2014-09-18T16:19:01+00:00

The port to for this two targets has been entirely developped by Ilia Sergachev (alias Il or xzcc). His source
can be found at https://bitbucket.org/isergachev/rockbox . The few necesary modifications for the DX90 port
was done by headwhacker form head-fi.org. Unfortunately i could not try out the final state of the DX90 port.
The port is hosted on android (without java) as standalone app. The official Firmware is required to run this port.
Ilia did modify the source files for the "android" target in the rockbox source to make the DX port work. The work I did
was to separate the code for DX50 (&DX90) from the android target.
On this Target Ilia used source from tinyalsa from AOSP. I did not touch that part of the code because I do not understand it.
What else I changed from Ilias sources besides the separation from the target "android":
* removed a dirty hack to keep backlight off
* changed value battery meter to voltage battery meter
* made all plugins compile (named target as "standalone") and added keymaps
* i added the graphics for the manual but did not do anything else for the manual yet
* minor optimizations

known bugs:
* timers are slowed donw when playback is active (tinyalsa related?)
* some minor bugs

Things to do:
* The main prolem will be how to install the app correctly. A guy called DOC2008 added a CWM (by androtab.info) to the
official firmware and Ilia made a CWM installation script and a dualboot selector (rbutils/ibassoboot, build with
ndk-build). We will have to find a way to install rockbox in a proper way without breaking any copyrights.
Maybe ADB is an option but it is not enable with OF by default. Patching the OF is probably the way to go.
* All the wiki and manual

to build:
needed: android ndk installed, android sdk installed with additional build-tools 19.1.0 installed

./tools/configure
select iBasso DX50 or iBasso DX90
make -j apk

the content of rockbox.zip/.rockbox needs to be copied to /system/rockbox/app_rockbox/rockbox/ (rockbox app not needed)
the content of libs/armeabi to /system/rockbox/lib/ (rockbox app needed)

The boot selector is needed as /system/bin/MangoPlayer and the iBasso app as /system/bin/MangoPlayer_original. There
is also the "vold" file. The one from OF does not work with DX50 rockbox (DX90 works!?), the one from Ilia is necessary.

Until we have found a proper way to install it, it can only be installed following the instructions of Ilia on his
bitbucket page, using the CWM-OF and his installation script package.

Remove I/O priority. It is harmful when used with the new file code.

2014-08-30T18:01:21+00:00

HAVE_IO_PRIORITY was defined for native targets with dircache.

It is already effectively disabled for the most part since dircache no
longer lowers its thread's I/O priority. It existed primarily for the
aforementioned configuration.
