OpenWRT + Python + LCD + Image Processing

• domotico [TS] on 08 Feb 15 @ 08:51 AM #

  Hello, this is a good topic kase minsan nagbrowse ako sa jobstreet may mga nangangailangan ng ganitong skills mostly mga device developments so its a good topic for question and answer portion and the best forum to show your projects or rigs for everyone to feast on
  
  para maging productive tayo, we need to know how we can comminicate with openwrt
  
  these are first things na dapat natin malaman: interfacing the device to computer via com port, usb at kung kailangan natin mag interface ng another device sa gpio ng openwrt device, we need to know how to interface with it using i2c, spi at can, aside from this we must have experience in linux and kernel development

  I am currently reading article \"How to use I²C over USB\" <click here for link>
  
  Kailangan ko kase makonnect ordinary lcd sa openwrt devices
  
  heto rin very informative documentation of i2c <click here for link>

  Openwrt Still has no support for SPI pero may gumagawa ng kernel para sa SPI communication, SPI is very important kase yung mga lcd karaniwan ginagamit ang spi at mga memory cards
  
  here is 1 nice example <click here for link>

  this is such a nice project <click here for link>

  ayos yan thanks for sharing these links and your strategy on how to start with OpenWrt

• jjtieng on 10 Feb 15 @ 12:56 PM #

  for those interested in hardware hacking want to play with openwrt, you may checktp-link mr3220

• scandinavian_armor on 10 Feb 15 @ 01:41 PM #

  ^actually halos lahat ata ng tplink mrXXXX supported na ng openwrt.
  
  btw, good initiative...

• jjtieng on 10 Feb 15 @ 02:19 PM #

  yung tp link tl702n hindi pa kase 2mb ram lang sya. the complete list can be found at openwrt wiki page

• jjtieng on 10 Feb 15 @ 02:20 PM #

  tl-mr3020 uses the same chip used by arduino yun, tlthough arduino yun uses the chip as for wifi or router purposes here, we intend to use the chip as the microcontroller na rin but since it uses Linux, arduino ide can run on this os and eventually can be used to program arduino compatible chips

  maganda ito kase di na masyado kailang magprogram, it seems may usb driver para sa webcam, monitor, mouse, 3g/4g modem, external hd drive, dvdwr, memory card, at kung anu-ano pa its a full featured computer, I wond kung pwede pagkabit-kabitin several of these for bitcoin mining?
  tp-3020 yata di pwede maginstal ng python kase maliit lang memory nya

  pwede naman basta ilagay yung installation sa memory card

• jjtieng on 15 Feb 15 @ 06:13 AM #

  this seems to be a good candidate for hardware hacking WR-NET-018-CC CD-R King Router, similar sya sa features ng tl-mr-3020 pero di ko pa nakita loob nya pero when I tried to search in alibaba, ang dami nyang kahawig na openwrt routers

  hello, nakita ko post nyo,interestd ako dito, bookmarked

• domotico [TS] on 18 Feb 15 @ 06:13 PM #

  welcome to the thread wendel, share ka naman ng ideas mo, busy ako,
  may idea pala ako, yung ram at rom ng tl-mr3020 ay pwedeng ma-upgrade from the current ram-32mb to 64 mb, at yung 4mb rom din pwede gawing 16mb, this is more than enough for ip cam or security cam application,
  
  yung 64mb ram pwede kunin yung isang ic desktop pc ddr2 ram, plano ko ipahinang sa mga cellphone tech kase subrang galing nila sa ganun, yung sa rom naman, di ko pa mahanap yung pwedeng ipang upgrade, pero iniisip ko baka pwede gamitin yung 4 na ic\'s sa ddr2 ram memory module

  di ba may 128mb na ic sa mga ddr ram? pwede kaya gamitin yun?

• domotico [TS] on 17 Mar 15 @ 12:31 PM #

  ang nakikita ko lang na mga openwrt devices hanggang 16mb ang rom at 64mb yung ram. it is not meant for heavy processing. talagang para lang sa mga embedded systems lang

• domotico [TS] on 18 Apr 15 @ 06:20 PM #

  di ba may 128mb na ic sa mga ddr ram? pwede kaya gamitin yun?

  
  
  mukhang magandang magexperiment sa ganyan, baka supported pa ng cpu, multeplexing yata tawag dun

• jcmpix on 19 Apr 15 @ 01:13 AM #

  yung sa rom naman, di ko pa mahanap yung pwedeng ipang upgrade, pero iniisip ko baka pwede gamitin yung 4 na ic\'s sa ddr2 ram memory module

  
  How do you plan on making this work? Will the router be powered constantly? Any trip and you lose your program. Baka okay lang yun, inconvenient lang na i-reload but not for applications that need high uptime and quick recovery..

  the device is just like raspberry pi, pero di sya ganun kapowerful, pero mas powerful sya kesa sa arduino, so suitable sya sa mga devices that does not require huge processsing, nasa gitna lang sya, ang suitable devices ay yung mga simple video/image capturing walang face detection di nya kaya sigurado, maganda rin sya sa robotics

  mukhang interesting ito ha, how big is it? can it be embeded to small projects that require low power, most of my projects kase kailangan tatagal batteries, looking also at energy harvesters

• jjtieng on 11 Jul 15 @ 07:02 PM #

  maganda yan sa smartwatch project, yung ang balang kong gawin

• wendellp090 on 12 Jul 15 @ 09:49 AM #

  nakita ko lang sa net pwede sya sa smartwatch ha:
