<p>Created page with &quot;= Roadmap = This list describes the things that would be needed to create a platform on which an alternative firmware implementation could be provided, roughly in the right order. * Creating an inventory of the components on the Barracuda board and their functions, and gathering technical information about these componentes where available. * Find out what the testpads on the Barracuda PCB do - Identifying <a href="/index.php?title=JTAG&amp;action=edit&amp;redlink=1" class="new" title="JTAG (page does not exist)">JTAG</a> and <a href="/index.php?title=UART&amp;action=edit&amp;redlink=1" class="new" title="UART (page does not exist)">UART</a> would be really helpful here. * Get a [...&quot;</p> <p><b>New page</b></p><div>= Roadmap =<br /> <br /> This list describes the things that would be needed to create a platform on which an alternative firmware implementation could be provided, roughly in the right order.<br /> <br /> * Creating an inventory of the components on the Barracuda board and their functions, and gathering technical information about these componentes where available.<br /> <br /> * Find out what the testpads on the Barracuda PCB do - Identifying [[JTAG]] and [[UART]] would be really helpful here.<br /> <br /> * Get a [[linux]] (console) shell to work on the current firmware to be able to get info about how the official software connects to the hardware. Memory maps, device drivers, etc<br /> <br /> * Figure out which pieces are missing to drive the hardware - Does Reciva provide drivers to all hardware ? Is a bootloader provided ?<br /> <br /> * Try to put as much pieces of the provided GPL code together to get a basic OS up and running. Find out how much Reciva added or modified of the original software packages.<br /> <br /> * Get all the hardware components working: [[GPIO]], [[LCD display]], [[LEDs]], [[Keys]], [[Mute]], [[Watchdog]], [[usb]], [[network]], [[audio]]<br /> <br /> = Architecture =<br /> <br /> A first rough graph of the software architecture.<br /> <br /> [[Image:Sharpfin.svg]]<br /> <br /> <br /> == libreciva ==<br /> <br /> [[Libreciva]] is a C library handling the communication with the reciva device drivers for LCD, keys, LEDs, mute, etc. the library provides sufficient abstraction to enable the development to be undertaken on other platforms.<br /> <br /> * [[LCD display]]<br /> * [[Keys]]<br /> * [[Watchdog]]<br /> * [[Mute]]<br /> * [[Log]]<br /> <br /> Note that the audio already uses the standard OSS, so additional driver interfaces are not required.<br /> <br /> [[Image:Sharpfin-screen.jpg|View of the Sharpfin Project LCD Screen]]<br /> <br /> == Testing ==<br /> <br /> * A small test utility is available for testing the libreciva functionality while developing<br /> <br /> == Sharpfin control app ==<br /> <br /> The sharpfin control application handles :<br /> <br /> * User interface: The userinterface consists of a menu structure for configuring the radio. The menu is controlled using keys and LCD using libreciva<br /> <br /> * Configuration database: The reciva control app manages a central configuration database with a friendly API to store and retrieve configuration data. Actual storage can be plain text files or any other format.<br /> <br /> * Network configuration: The control app is responsible for configuring the wireless network using wpa_supplicant, dhcpclient, ifconfig, etc<br /> <br /> == Sharpfin audio app ==<br /> <br /> The sharpfin audio application handles the playing of audio. It is implemented as a daemon process which takes commands from the control app. The audio application handles:<br /> <br /> * Retrieving audio from disk or network (libcurl?)<br /> <br /> * Decoding audio using various libraries (libmad, libogg, etc)<br /> <br /> * Resampling the audio to the fixed samplerate used by /dev/dsp<br /> <br /> * Sending audio to /dev/dsp<br /> <br /> == Webserver ==<br /> <br /> The HTTP server can be used to control and configure the radio using a web browser.</div>
