Hi Temtronic,

sorry about that, the solution was indeed as sugested by Jeremia and Jerson.
I thought that was fairly obvious.

copying the string to and from the Struct was not being done proper ...

I would like to take a moment to thank you both for the help!
I have clean, fast data, switching processors now thanks to your help.

THANK YOUUUUU!!!!!!!

side note: Jerson i see you are from bombay!
I used to spend all my summers(3 Months) there for 5 years! Ive been to every province in India.
learned to jugle in [spam]. mastered Table Tennis in bo ...

Thank you Jeremia and Jerson!
I will be trying this ASAP!

In the code provided im casting an int32 as a float.
I have tried straight float to float, with similar results.
I tried manually writing values and still fails.

its a regular PIC float, which i display as %3.2f as usual.
simply doing

Float#1 = Float#2;

Im not using any IEEE formats or anything, just straight CCS floats.

Hi Guys, ive been fighting with this for a few days now. It feels like looking at Schrödinger's cat.

PREMISE:
Im building an application/board where i have 2 PICs - one handles the machine itself ...

Ive added a conditional to the Error calculation.
Basically if im with 0 to 2 counts away from the setpoint just make error =0.
Good enough = 0 error jajajaj

So basically starting from 0 if i set ...

i was calling my compute function within the TMR2 ISR which was executing at 8.2ms more or less.

othertimes in dispair i would call Compute_PID() from within the main loop and nothing else... and t ...

That makes sense... i may be atributing super powers to PID.
However i see in youtube plenty people reaching precision with similar hardware.

How can i test this?
Should i set this to accept valu ...

PWM has to run from fosc/4... so im at the lowest feasable PWM freq. Which impacts my execution time clock so, slower loop times too.

I know its possible to go lower with other osc configurations b ...

Ive played for hours with the P/D gains... keeping Integral at 0.
Ajusting loop times too...when semi acceptable peformance is achieved i add some integral... more.hours... no improvement.

Is my m ...

higher/better power supply did not bring any changes... it settles a bit faster, and the motor gets a bit warm when oscilating.

im having the same behaviour, just faster jejejeje...

Im gonna run this again with a 24V psu:
