FNIRSI-1013D "100MHz" tablet oscilloscope

Hopefully the author of the application will forgive me and allow minor changes.

If someone wants to play, otherwise don't use it. Since the updater in the oscilloscope is functional, changing the oscilloscope software is quick.

I just discovered this firmware, looking at 136 pages of messages..

I have a plain stock 1013-D scope.
I would like to explore this new firmware, especially if I can get a true roll waveform, where the trace constantly fills in on the right and rolls off the left instead of the factory "roll" which starts at the left and restarts when it gets to the right.

But where do I start? 
The "latest firmware version" directory has two text files, seven and eight months old. I can't read them, I just get jibberish on the screen.

What is the process to migrate from the factory firmware?

[Atlan]

This mode is not supported. The files are in the link and there are videos on how to do it READ README). And I think the videos are 1 or 2 pages back.

[rozwell]

This mode is not supported.

Would be pretty amazing if it was 

[Atlan]

updater 0.02n added SPI flash presence check, and write verification.
It is not necessary to upload it.

updater v0.02r
DSO firmware v0.27u" // turn off picture delay on dev mode, improve find trigger on 50% level, have trigger-green, positionlimitHL change
The waveform should not jump from side to side. If the correct trigger is not found, the waveform will not be displayed.

updated.
ok so far.

I plan to end support for the original Fnirsi1013D firmware. It will no longer run on the oscilloscope. Are you still using it and why?

I do not, it's inferior and lacks too many features.
Moreover, if that means even more upgrades, I say go for it!
People who upgraded the firmware weren't happy with the original in the first place

[facekim]

I still use it; it's the only tool I have for diagnosing cars.
In any case, I'm always grateful.

You're still using original firmware?!

[Atlan]

The code for the FPGA is written, it works more or less the same as the original (I'm not sure if that's good).

Those who have FPGAs with the AL3a10 chip are better off than those with the EF2L45.

The AL3 has content for the FPGA in flash on the board, by desoldering the flash with the FNIRSI firmware, it is possible to program the flash for the fpga after soldering 4 wires. In addition, the AL3 allows a sample memory of more than 16000. (now 3000)

The EF2L45 has the program in its internal flash, so you need a programmer. moreover it is smaller so that the max memory for samples is about 12000.

What I have ready is AL3 with 16000 samples, possibility of setting the trigger from 0 to the end of the memory (practically only 3 in the offer: 25% 50% 75%), 1kHz output signal generator square (possibility of setting the output from 1Hz to 25Mhz - of course the higher the frequency the bigger the jump)

what I don't have ready but it is in the plan: Hold function in the trigger

By unsoldering the FLASH at the uP where the fnirsi firmware is located - it will no longer be possible to run it. Moreover, after changing the firmware in the FPGA, it will no longer work properly with the fnirsi firmware. But the advantage is that you will have the opportunity to change the firmware for the FPGA on the AL3 chip directly from the UPDATER interface of the oscilloscope.

Did you solder the RTC module onto the PCB?

[gadak222]

Yes modul installed into scope, firmware 0.25 work saving RTC. With firmware 0.27u not saving

[rozwell]

Looks like the end of version v0.x and a huge upgrade for those willing to do the mod.
Sounds awesome!

[Atlan]

Measure the battery on the RTC module, or replace it immediately.

Well, I only use the FNIRSI firmware when I need to check signals above 10 MHz or run an FFT.
Even though it isn’t very reliable in terms of accuracy, it’s still useful.

So, does that mean there will be a 4x to 5x increase in memory depth? That seems VERY significant.
Will it be compatible with both models? Are there only two variants?
My unit only has this number, and the ADCs have their markings scraped off.

Probably Al3, if you took a picture of the whole board....... on the left there should be 2 connectors, one for the FPGA flash 6pin and 4pin for the useless encryption circuit. Next to them is the FLASH memory.

As far as I know, the tablet version has 3 PCBs. 1x AL3, and 2 versions of EF2. That's why I'm surprised that they produce modified boards but not that they fix the software.

[rozwell]

Is the AL3 newer or older?
If I were to buy a new unit, which FPGA would it have?

[Atlan]

Nové majú EF2

So, how do I get my 1013D to connect to this?

4pin/6pin connector - detected
Looks like I got lucky? 

The software will never be updated, and the company’s support is terrible.
When I received my unit it wouldn’t even turn on, and they told me to fix it myself — unbelievably stupid.
You can be sure they follow this thread, and they absolutely hate it.

Great pics Tnx
But maybe 3-second black screen delay isn't needed if there's no scope.bmp file on the SD card?
