Re: OpenXsensor Configurator
Yeah, sorry. It was definitely too late for me..
As I stressed on my post above, I am not criticizing, far from it, I'm just trying to help
Thank you for this configurator. It will make our lives a little easier..

I've a pretty clear idea of what I think is good for the first release, then, we could make further changes based on user experience.
Re: OpenXsensor Configurator
Hi,
Second beta !
Now, you have to use the write button
The aim (if you accept the mission), is to check if the configurator can spot every possible mistake we could do in the settings. As you probably guessed, all the tests code is activated by the famous write button so...
I've also replaced all the text field entries by number boxes (clic and drag horizontally), because the library I use for the GUI doesn't handle them very well
Good luck

Re: OpenXsensor Configurator
Hi João,
Yes, temperature is disabled because I was using a MCP9700A sensor with a special compensation error calculation, and mstrens found it too restrictive and preferred that it be done with a volt(x) measurement and some offset settings.
It's, indeed, possible, but I couldn't do that, as I don't have a thermometer to calibrate the sensor. So I kept it in the configurator and I'll use it with a special OXS version...

Re: OpenXsensor Configurator
Ok, First impression, still didn't flash the arduino, I'm only playing with it at the moment
It took me a while to find out how to change the divider ratio for the voltages.. But i found out that I must hover the mouse over the numbers and turn the wheel.. On the offset though, it takes a few spins to change the number by one
Also, could the configurator calculate the maximum voltage allowed for that divider? You can calculate it based on the reference voltage and divider ratio, correct? Then you could display it under the offset. I think that would help people not to use the wrong divider by mistake and destroy the arduino because they applied a too high voltage due to a wrong divider.
That is what I found for now..
Great job. Thanks
João
EDIT: What value should I insert for a 4:1 divider? 4.00??

Re: OpenXsensor Configurator
Splendid work,
according to the dividers: what about reading the 2 resistor values instead of their ratio?
@João: If you hover over the number, try to press left button and move mouse to left or right.

Yes, the divider factor is what you put under the line with 1 aboveWhat value should I insert for a 4:1 divider? 4.00??
To be more accurate, you should measure your resistors with a good multimeter and put the right value in the divider factor field, that's why I've set them up to 2 decimals.
It was a possibility, but I wanted a simple, compact interface and if you're using more than 2 resistors ?KAL wrote:according to the dividers: what about reading the 2 resistor values instead of their ratio?
I will work on wiki documentation to explain how to use and set up OXS with OXS Configurator.
Thanks for your feedback guys !

Re: OpenXsensor Configurator
Ah yes, that works with the m0use.. thanks..
With the resistors is also an excellent idea.. we would just have to measure the resistors with a multimeter and insert the exact values.. That would be accurate as most multimeters have an error of aproximately 1%.
I remember that the oXs calculated the divider that way in the beginning, and I did like it.. no offset needed even if it was there. and the voltage was accurate.
with the present calculation, when the voltage should be 0 it displays 0.1 at times. Don't know why.. But it is accurate when reading higher voltages.. Still prefer the old way as I said above, so if you could do it that way, it would be greatly appreciated
João
EDIT: Davx, what do you mean with more than 2 resistors.. even if you insert a third resistor in series with the arduino pin, only the 2 main resistors count for the calculation.. Also if you make a series with 2 or more resistors, you can measure the value of the series with the multimeter and insert it in the configurator.. That would be easier and user friendly for the people because they didn't even have to calculate a divider as it would be done in the program by using the resistor values.. The people would just have to insert the correct resistor values. easy peasy Many people, like me, can't calculate So I'm a good example

Re: OpenXsensor Configurator
Hi.
Klaus (aka KAL) pointed me to your OSX Configurator.
Good idea to have a linux version! Have several (stupid) questions about some functions, I have seen.
But first of all, tried to put a link on my linux desktop. Funny, could not link the executable directly, but had to create a bash file in my home folder, which then could be linked to an icon on the desktop.
Now it looks good!! Nice icon!!
About those (stupid) questions. Have to sleep over it first, might solve some

It's a good idea but there is more to consider, the resistors values have a meaning, we just can't put any resistors with just a right divider. As I am not an electronics engineer, I've to find again a good post somewhere which was explaining how to choose the resistors value.jhsa wrote: With the resistors is also an excellent idea.. we would just have to measure the resistors with a multimeter and insert the exact values..

Re: OpenXsensor Configurator
To get a good analog to digital reading the resistance of the voltage being measured must be less than 10K.
If using a voltage divider, then this means the PARALLEL combination of the resistors in the divider must be less than 10K. I know that sounds odd since the resistors are in series as a divider but that is how it works.

Added a bash script inside the OXS_Configurator_v1.0_linux folder with those two lines

Re: OpenXsensor Configurator
Of course people can be suggested a value for the resistors but that's not the only point to consider in my opinion. In any case people will have to measure the exact value of the resistor to achieve the right value for the resistor. Some people might not have that value of resistor and have an aproximate one. Like for example 1.2K instead of 1.5K. That won't give an exact dvider for example. I know we can go to online voltage divider calculators and see the ratio, but some people might not be able to. An the formula is still a formula. I think that by inserting the values of the resistors, the result would be more accurate, and and if it can be implemented, why not? After all that is the reason why you wrote this configurator, right? To make it easier to the people by avoiding all the calculations we had to do before.
I did find the way Rainer did it before more accurate than the way it is done now. And easier.

Re: OpenXsensor Configurator
That is used for example when you do two flights or more with just one lipo and you have a current sensor on board that reads the used capacity. The amount of charge you have taken from the battery on one flight will be stored in the oXs eeprom. So when you fly the second time, it starts from that value and not from zero. This is normally used with a push button connected to the arduino so you can reset the value to zero when you put a new battery in the model..

This feature needs some thinking to make it right, and I want to write some docs, and my time is limited, and...no, nothing more
Code: Select all
#define RESISTOR_ANALOG_TO_GND 4700 // 4.7kOhm resistor
#define RESISTOR_ANALOG_TO_BATTERY 15000 // 15kOhm resistor
Code: Select all
#define RESISTOR_ANALOG_TO_GND 4732 // 4.7kOhm resistor
#define RESISTOR_ANALOG_TO_BATTERY 14970 // 15kOhm resistor
So what I have been talking about is something like this:
Voltage Number - (All the Cell 1, cell 2, cell3, etc..
Pin Number - A0, A1, A2, etc, as you have now..
R1 (to Batt) - 15100 (Ohms)
R2 (to GND) - 4760 (Ohms)
Offset (mV) - Same as currently
Range (Or max Voltage allowed) - 20.86V This would be calculated based on the resistors used and the arduino reference voltage. In this case 5V.
So basically the code could make all the calculations based on the reference voltage and the resistor values. Much easier to understand for the normal mortal people that doesn't understand anything about mathematics
That is how it worked before. Sorry if I'm not very good explaining stuff. It is as bad as my math, believe me

Re: OpenXsensor Configurator
Question/suggestion to current parameters:
The output offset for bidirectional current sensors has to be set at about half of Vcc.
Can/should this be managed by the configurator or is it sufficient to mention that in the future documentation?
What also puzzles me a bit is the offset in mV for a current measurement...

Re: OpenXsensor Configurator
when you calibrate a sensor, you have to look in the datasheet. And as the sensors send out a voltage that is proportional to the current, the datasheet says that for zero amperes, the sensor outputs (x)mV. That is why the offset is calibrated in mV
