BenF 3.x FW on new LCD driver devices [flick. screen solved]

by palindrom » Tue Oct 08, 2013 5:27 am

[EDIT 2]
rimidalv007 patched BenF 3.64 APP + 3.53 LIB and it can now operate on ILI9341-equipped devices.

[EDIT]
Thanks to the work of rimidalv007, we now can use BenF 3.11 firmware on ILI9341-equipped devices!

[/EDIT]



It seems that many users, like myself, are stuck with official firmware due to LCD driver mismatch (9341 vs 7781).
As far as I know, BenF isn't interested in solving that issue and there's no source code of his work available.
I won't risk buying another device just to find out that I got unlucky again, it's pointless.

I'd love to know is there really any reason for me to stick with device that will be impossible to upgrade. Right now, the measurement menu of 4.22 official firmware shows trash in most of cases. Especially frequency measurement fails badly. It would be nice to know if I should go hunting on eBay for working option if I can't get DSO running a bit more reliably. It is the case if BenF abandoned his project and don't want to give away his solutions for free, which would be perfectly understandable. I don't know that, I couldn't get in touch with him.

So I'm asking you all if you have any info on BenF plans and/or other working firmware options.

If anyone have source code of BenF 3.64 APP and 3.53 LIB please contact me urgently.
I have a source code for 4.22 original firmware which handles ILI 9341 display so it should be possible to run BenF 3.64 on new devices.

Is this something you can share? Is it available or published somewhere, or did you get it under some kind of NDA?

I didn't get any notice about terms of use. I asked for firmware and got it.

Thanks for posting that firmware source drop. That's cool they let you have it. It should very much be possible to update the BenF firmware to support these newer devices if we had his source. I can't believe he won't make it available. I'd be willing to put time into such a project.

We have the sources for BenF's firmware, just not the latest version. He has previously stated that he does not see any reason to open-source his software if nobody makes something out of it.

This is a good opportunity to make use of the available source code. It should not be too difficult to paste the 9341 display routines into the old firmware code. The work can easily be forward-ported if we ever get hold of newer firmware sources in the future, or be picked up by BenF if he is interested.

I'll try to help out with code questions if someone gives this a stab. I have even bought a 9341 LCD module in the hope of testing out firmware code on a STM32 development board, but unfortunately the module has only SPI and not parallel interface so I can only verify higher level display code but not the exact driving code. Getting something on the DSO screen in the first place, by developing "in the dark", is the greatest challenge.

I'm just a lurker (and not a programmer) chiming in to applaud you for your efforts to get the BenF firmware to work with the newest DSO201's LCD. I have one of these but it's useless to me until I can run BenF on it. Please keep us updated on your progress!

I'm another disappointed newbie who stumbled across the lcd driver incompatibility with my recently purchased v1. Can someone point out to me where this issue originally surfaced? And my best wishes to anyone who can modify BenF to make it useable!

Maybe the task of adding the new LCD support to the open-source BenF version is something that can be crowdfunded? I think I should be able to do this but I would need a unit with the new LCD to work on. I don't even need to keep it, but I wouldn't like to just borrow someone's precious unit since my testing could possibly damage it. If enough of you pitch in for a Christmas gift, I could find some time in my Christmas vacation if not before :)

You can count me in for a bounty on new LCD driver compatible firmware!

I've been looking at the 4.22 firmware source and the available open benf firmware, but I'm lost. I'm in the novice stages of Arduino development, and just started playing around with programming AVR's with USBasp and the Arduino IDE... I recognized just enough code in the benf source to get a very rough idea at what was going on in some of the files, but when I looked at the Chinese 4.22 firmware I got lost, there's quite a bit of foreign characters in there...

It'd be great to get someone that knows the ins and outs of this hardware and software to make a 3rd party firmware work, and possibly breathe some new life into the development in general.

I upgraded BenF LIB3.01 APP 3.11 for new LCD. If someone provide me newest BenF source I will do same on it.

Enjoy my friends!
