Anyone have information on the Dingoo LCD and GPIO of the JZ4732?

By -

Over at the Spanish GP2x forums, booboo made this observation:

booboo booboo is offline

Definitively better to carry rockbox.
In the FTP of Ingenic there is port of uCOS-II for the JZ4740, so it would not have to be very complicated. Nevertheless, also there is port of linux, so it is, at least, EQUAL of complicated. Positions to invest effort, better to do it with linux, since there is much more developer and software that uCOS-II stops. Kernel of linux certainly occupies more ram than the one of uCOS-II, but with 32M total I do not believe that the difference is significant.
I already have datasheet of all the integrated of dingoo, with the exception of the energy management (conversion and load of battery). The unique thing that is needed is that, the information of the LCD and configuration GPIO of the CPU. This last one can be found out by means of reverse engineer, and the LCD controller I suspect that it is a ILI9325, than nothing by the name the file more (and text chains in the interior) that comes with the application from unbricking.

Doug made the same observation about the LCD screen in a comment on this post on March 23:

Hi, Gadgetmiser. Here is Doug again. Currently I am looking for more detailed information about Gemei X760+ LCD and Dingoo A320 LCD, like manufacturer, model, framerate, etc. If you, or any blog visitor can help me with this information, I am grateful.
PS. Your blog is great. You are making a excellent work. Congratulations... :)

Translation to a non-Tecchy like me: if information on the LCD controller and GPIO of the CPU can be found, we will be that much closer to Linux on the Dingoo. I reckon, at least as close as Carpathia was to Titanic!

Dingoo A380 Review

By -

The nice folk at isharegifts gracefully sent me a sample Dingoo A380 for review. Having declared my pecuniary interest, in truth though, after playing with this new Dingoo, bribery and graft is strictly unnecessary for its promotion.  IMHO, the product does stand on its own merits.  It remains a testament to the original A320, and its rabid, passionate community (hey, that’s us dudes) that even in 2011, some 3 years after the word “Dingoo” became somewhat a part of the English language,  that it still remains the best Dingoo-type device.  This is because it is still the best supported, thanks to Booboo’s original Dingux, and now OpenDingux.  Dingux means access to emulators and software other than those that came with the original A320’s native uCos firmware.  Dingux allows for ports of games like Doom and Duke Nukem.  Dingux is what turned the A320 from a glorified media player into the device we know and love. It’s still necessary to put Dingux onto a stock standard A320 thoug

With the release of FAT Dingux, it is now possible to install Dingux using only Windows!  As promised, here is The Complete Idiot’s Guide to Installing Dingux – Using Windoze Edition.  Grab the guide here in PDF , zipped here , or here for HTML . 18 October 2009 Update:   The above links will always contain the latest version of this guide . While the guide was written in July 2009, the technique shown in it remains the same as at the update date shown in green.  However, the guide refers to toddler’s or warped flash’s “local.zip” files, and contains links to these files, which are outdated. The links used to point to the A320 freeforums, until the dastardly Dan deleted them ! Grab the latest version of the critical local.zip file, referred to in the guide here: http://boards.dingoonity.org/index.php/topic,32.msg80.html#msg80

A somewhat new game for Dingux from ZX-81: Dingux-Mancala: A Mancala Game v1.1.0 for Dingoo/Dingux Hi All, Mancala is a board game familly, originated in East Africa. The word "Mancala" came from arabic word "naqalah" that means literaly "To move". Dingux-Mancala is the "Awari" variant, and even if the rule of this game is simple, the complexity can be compared to chess Game. The AI is based on the source code of H. Huseby & G.T. Lines, for their implementation of the classical Minimax algorithm. How to use it ? Everything is in the README.txt file. Sources are included, and this package is under the GNU public license, read COPYING.txt file for more information about it. How to play ?

The Dingoo-Scene JXD S7800B (Rockchip 3188 SoC) Android Gaming Console Review

By -

1. Introduction      Since the introduction of the somewhat venerable Yinlips YDPG18, Android handheld gaming devices have been released pretty much continuously, by any number of Chinese manufacturers.      They’re not released with retrogaming in mind however.  Dedicated Android handhelds with physical controls for the consumption of nostalgic childhood memories are simply not in great demand in China, and accordingly, these devices have never been well supported by their makers, as far as the multitude of little tweaks and twerks that the Western retrogamer demands in the quest for ultimate emulation fidelity are concerned.  The view of China based manufacturers seems to be that the physical controls are an adjunct to the primary function of the device – hey, it’s an Android tablet, what else do you want?  Foremost among such frustrations has been OASS: “ornamental analog stick syndrome”, which sadly afflicts many of the devices released to date. What use are any physical cont

Tauon PC-1 review

You should give this a chance. It deserves one. Welcome to the Tauon PC-1. A Tauon is an incredibly  geeky sciency thing , as it happens, and has nothing to do with the  Great Eastern Philosopher . You won't find it for sale anywhere other than on Tauon's website , and on ebay so far as I can see,  and then only if you're a regular visitor of the ebay "vintage computer hardware" category.  It won't even turn up on ebay if you search for the product name: "Tauon PC1"  - you'll just stumble upon it one day, when you're looking for a replacement floppy drive, or a C64.  So, what is it? It's a computer in a dinky little case! Hardware wise, it has: Allwinner H3 Quad Core SOC [1ghz to 1.2ghz/1gb RAM/8GB internal NAND storage] SD slot USB slot,  HDMI and composite out Ethernet Wifi UART (send/receive signals through terminal commands) I2C (drivers aren't ready yet, but promised).   Inside the case - y

How to show all your 17,083 c64 games from the c64 romset (archive.org) on the C64 Mini or C64 Maxi loader

Update 4 January 2020: ================================================================== New, much friendlier GUI version released - see this post: https://dingoo-scene.blogspot.com/2020/01/gui-version-of-gadgetmisers-c64-romset.html ================================================================== Hello, friends, it's been awhile.  A happy 2020 to you all. If Santa was kind this year, he may have brought you one of these:   If Santa did, you'll have worked out by now that 64 built-in games, classics though some of them are, is simply  not enough .   Your travels may have led you to this c64 romset:  https://archive.org/details/C64Romset , which contains 17,068 games. If you pop them on a USB stick and slip it into your c64 Maxi/Mini, only the first 256 games will appear.  This is because there is a limit of 256 items per folder that can be displayed on the c64 mini/maxi loader. So you need to split the games into individual folders, each containing n

An interview with the creator of the Tauon PC-1, Volodymyr Mishin

By -
I'll bet you don't roll out of bed and think about making your own PC before breakfast.  Even you do, I bet you haven't actually  shipped . Here's someone who has.   I reached out to the creator of the  Tauon PC-1 , Volodymyr Mishyn who kindly took more than a little time to answer some detailed questions about the PC-1, how it came to be, the challenges of a project like this, his future plans for Tauon OS and what is clearly a very personal labour of love.   Many thanks Volodymyr.   Your  news blog  suggests 30 days to prototype, and 6 months to ship! If that is right, it is very impressive, given the technical and logistical activities that had to occur.  Is there more to this story? I was looking for available options before I started the project. I got myself a couple PI (3B, Zero) OrangePi, C-SKY. And tried to build some kind of educational PC for my kid. Unfortunately, the performance was awful, using Linux was too complicated even for me (I h
