Okay thank you guys for information.

We will use option #1, any PIC to send data to PC as in control. Heavy work will be done in PC that will register all data and compare persons.

Probably I should read about bmp file to understand details actually me and my friends working together and I am gonna say him about dspic to search suitable device.Thank you again friends.

Hey Jay, of course I know shifting. I asked actually why this shifting used, actually it was probably about sinusoidal wave. >>10 is val/1024. I didn't realised it and I didn't use like that ...

Hi guys, I am trying to understand how to use sinusoidal control. I have codes someone did it. But I couldn't understand somewhere maybe someone have this experience, maybe can understand the basic po ...

Hi guys, I am going to use fingerprint sensor and the values that I have got are about 34000 and datasheet tell me:

ImageBuffer serves for image storage and the image format is 256*288 pixels.
Whe ...

Actually I can't set it any new rpm that is lower than previous rpm. Just I can set it for higher rpm. Why it behaves like that ?

y[n] = y[n-1] + A0 * x[n] + A1 * x[n-1] + A2 * x[n-2] * x[n]*e[n]

x[n]*e[n] comes back calc using z transform. x[n] equals current limited value for pid. I couldn't write for a while sorry for that ...

rpm = bldcObj->func.Get_RPM(bldcObj);
//rpm = kalman1Dobj->func.Calculate(kalman1Dobj,rpm);
err = setRpm - rpm;

saturation=err;

if(err>3000) satur ...

Hi guys
Codes below control the motor speed with PID but I have a problem. If I change the speed like rpm=1000 and then rpm= 100. PID calculation produce very big negative value and this is why I c ...

Okay it is not about resolution. If I put there delay_ms(3) there is no problem. I have to handle it, but do you have a nice solution ? Of course I can apply.

Now it works yes It moves ccw for trying but new problem is after a while when motor moving it is getting slow and stop for a moment and again moving. I am thinking about resolution. This is the algor ...

Probably I couldn't tell its right because language. I mean I couldn't move the motor for next commutation. Of course I can read motor position. But if I need to find motor position for commutation in ...

Hi Ttelmah, I didn't understand what you mean exactly. Encoder give uint16 0-1023. I converted these value using asin(sin(enc_val*(360/1024))) to get result in -90 and 90 in this case I can take the ...

Hi guys,

I would like to sense commutation sequence using encoder (1024 resolution) for bldc motor and if current state - previous state >= a then motor can move for other sequence but if enco ...
