Hantek2000 bugs and wishes (2c42,2d42,2c72,2d72)

Fixed firmware avaliable:

My Hantek2c42 often doesn't pass the calibration. It freezes on it! I wait for more then 5 min, nothing changed. Fixed!
A problem also with DMM. In "DC mA" is not zero even when i cross the probes. It always show 0.02-0.05 mA, without probes also. Fixed! (the flux between +battery (J1) and shunt resistor 1 Ohm wasn't washed)

Please make some changes in the new firmware:
0. Add some functionality to export saved oscillograms to PC.
1. Add Menu hide (toggle) on second pressing "Menu", "Trig", "Channel", "Time". (MyFix)(HantekHTXAxGxP0001)
2. In Channel mode change LEFT<->RIGHT buttons, in Time menu UP<->DOWN! (MyFix)(HantekHTXAxGxP0001)
3. Add horizontal scale settings during operation. At least option to see all the signal on the screen but not a part of it! (somesing like 1:1 or 1:10 in analog scopes)
4. Make working icon about channel coupling AC,DC, Gnd. (~,–,x). Fixed! (2019022001)
5. When menu is hidden. Make changing of arrow buttons usage: "F1" - CH1 changing, "F2" - CH2 changing, "F3" - trigger changing, "F4" - time changing. Without showing this menu! Only arrow buttons function changing! (MyFix)(HantekHTXAxGxP0001)
6. Change word "Double" to "Both" in triger edge selection.
7. DMM Buzzer mode. Bug with sound, after shorting it say "Pi-pause-piii" but not single "Piii". Very slow measurement near 8-10 sec before value is stopped. It better to mesure voltage, not resistance.
8. In "Trigger" mode change buttons "<-" and "->" form changing trigger level to changing trigger position, like it does in "Time" menu.

What about adding some new not documented features, for example X-Y mode etc. Can it be possible? Fixed! (X-Y pressent in2019030201)

Done. Verification OK.
Seems the calibration freezing been fixed, thank you.

But something wrong, firmware version didn't changed. Is it OK?

"Menu">"Sys Info"
SOFT : 2018120601
PCB: 0000000001
FPGA: V02

Can you tell me something about my wishes, will you change it, how fast?
I need more information to make nice video overview about it (in russian).

May be you need some help with programming?
Contact me freely by email.

New bug found!

Cant measure more then 399V DC or AC in DMM mode.
Drop voltage in diode mode maximum 0.999 V.

Fill it be fixed? And when? What about other my questions?

399V problem is solved. Resistance measurement was with error.
There was burned resistor R15 (1k).
It was a little brownish, and was changed to new one.

Ok, I have given feedback our engineer. Will be modified in the next firmware.

Amy, please give feedback to the engineer:
Some way to hide (toggle) menu on the screen. For example by pressing menu button second time.

Please swap buttons left and right in channel menu mode. LEFT button must increase volt/div. RIGHT button must decrease volt/div.

Please swap buttons up and down in time menu mode. UP button must decrease time/div. DOWN button must increase time/div.

Sorry, we do not plan to add.

Please answer, will you modify what I asked?
Menu hide on second press.
Exchange up-down in time-base setting.
Exchange left-right in voltage-base setting.

Do you perform some work about this device, or it is a final releace?

I also would like to add a vote to weight in favor of some improvements to this device, specially:

...

You didn't understand me about Up-Down keys.
I am speaking not about changing UpDown to LeftRight.
I am about exchanging Left and Right in voltage mode.
Also exchanging Up and Down in time mode.

In all normal oscilloscopes V/div and T/div are inverted for more intuitive using, but in this in not!

Я полностью согласен, это увиличет и скорость работы ...

Я не думаю, что это станет возможным, особенно не в ближайшей перспективе. Судя по глюкам и ошибкам в прошивках за последние пол года, им уже катастрофически не хватает оперативы, динамические массивы налазят друг на друга... Тут нужно сначала оптимизировать и исправить то, что уже есть... Но похоже им впадло этим заниматься. Может причина в том, что они хотели запихнуть туда всего и побольше, а в итоге ничего толком не работает... Вот нафиг там этот глюкавый мультиметр нужен? А с компом соединение для чего, если даже нет возможности передать сохраненную осциллограмму? Гальванической развязки с USB то нет! А вообще, с таким подходом надо было ставить не STM32F103, а STM32407, тогда может уже можно было релиз рабочий выпустить. Повышенная производительность и увеличение памяти в некоторой степени компенсирует рукожопость программистов.

what about make menu hide on pressing "Enter" or "Menu" second time?
Change button Left<->Right in Channel Mode (voltage/division)?
Change button Up<->Down in Time Mode (seconds/division)?

Is it so hard to make this changes?
Please! Do it!

I'm sorry, but the engineer hasn't arranged the time to modify it yet.

I modified it already by my self...
Its a pity that thous engineer work in Hantek.
