Hello guys, i'm working with the input capture to measure frequency from 2 Hz to thousand Hz.
I was using dsPIC33, 80Mz, 40 MIPS, with 16bit timer 2.
If prescaler = 64 theoretically I can measu ... |

In an application this small and fast I wouldn't bother with CRCs or checksums. Just refresh the motor control commands every 10ms or 25ms and if one occasionally gets corrupted the trajectory will n ... |

I can see both sides here, one PIC versus 5 PICs, having done both methods.
Using only one PIC you save on the R&D time to cut code to send/rcv data to the other 4 PICs which should(_must_) hav ... |

why so many pics?
cant you do all in one?
For ease of development and flexibility the One_PIC_for_each_major_function method is good. You write one set of code for the motor controller and put ... |

Thank you all!
The first pic has a very robust control that has high processing costs, I tried using just two dsPIC, one to control the robot and another to control the motors.
But my dspic33fj128 ... |

I'm trying to do a speed meter, using three Hall-effect sensors 60 degrees out phase.
To do this just need to know the time between two edges of ascent or descent of the sensors.

Not sure if this will help, but this is the code I use to change spi settings between calls to my flash and my gyro. This is all on a PIC24FJ256GA110, but it should be similar to yours:
