"Try to run the PID controller at 100Hz and see what happens. If you notice a better performance then you have to increase the frequency sensor read and see why is unstable, some how. How unstable is? some Hertzs?

hi guys- just a quick question. i want in my program to run 2 separate loops -a control loop - running at 120Hz with a runtime of ~6ms,and a communications loop - running at 25Hz with a runtime of…Continue

Edi Gotlieb replied to Edi Gotlieb's discussion help please with some software design."the sensors(orientation) are read in the control loop itself (thats part of the problem) and that loop runs at aprox. ~160Hz - but the frequency is unstable."
Juan Gomez replied to Edi Gotlieb's discussion help please with some software design."Edi,
how fast you get the orientation of the quadrotor? If you are planning to run your control loop at 100Hz "for example" you must have new data of the orientation before calling your control loop. (The code needs new…"
Edi Gotlieb replied to Edi Gotlieb's discussion help please with some software design."thanks for the reply,
I dont quite understand what you mean by implementing FSM. do you mean that i should use this method only when reading my sensors via I2c? what will this give me? save time?
Or do you mean to implement this method for the main…"
Juan Gomez replied to Edi Gotlieb's discussion help please with some software design."Hi Edi,You should use Finite State Machines. This kind of structure, will let you handle task, like some kind of "non-blocking Task". State Machines are well situated to be implemented on I2C protocols, "without…"
Edi Gotlieb replied to Edi Gotlieb's discussion help please with some software design."because then i wont know how things work...i figured i need to do it once myself and then if i want then build on arducopter"

"Why do you invent the wheel by your own .... again?
Why not use the working Arducopter setup and improve that?"
Edi Gotlieb replied to Edi Gotlieb's discussion help please with some software design."anyone care to share there opinion?"

hi guys- just a quick question. i want in my program to run 2 separate loops -a control loop - running at 120Hz with a runtime of ~6ms,and a communications loop - running at 25Hz with a runtime of ~3ms. to do this i set up 2 timers (using the Atmega2560) to run at these speeds...now here comes the tricky part- i cant run the loops inside the ISR since the arduino framework doesntallow nested interrupts which is required to read the digital sensors and receive incoming serial data and PPM…See More
