x10 Probe

[QuentinC]

Hi,

First, thanks a lot for your work, it's great and very usefull, I'm gonna use it everytime ! But something else I've seen: setting the probe to x10 dont change anything on the screen display, shouldn't it show somethine 10 times higher than in x1 ?

Thanks !

Quentin

I know about this issue, I was too lazy to implement all these functions :) I will fix it later

Hi Gabonator,

I notice there have been a few updates since I last installed the software. Has the X10 issue been resolved yet please

Thanks

I am sorry, but this issue hasn't been resolved yet. I will close this issue when it will be fixed.

Hello everyone

As a new owner of the DSO203, I installed this firmware and I also noticed the bug. Since it is not fixed yet, I tried to fix fixed it. With my changes, the displayed resolution is automatically adapted depending on the probe scale factor.

I post the modifications here so that everyone can do them and I hope that they will be added to the current firmware

Is it in the new code yet please?

[QuentinC]

Not yet, I've made a pull request from my fork: https://github.com/QuentinC/DS203 You can clone mine to have the probe (working well), but it isn't in the main repository yet !

[FR4NK5T3R]

Hi QuentinC I would really like to get X10 working on my DS203. Can you tell me how please

[QuentinC]

The updated binaries are in my rpo: https://github.com/QuentinC/DS203 ! I've sent a pull request !
