Hi all,
I need to be able to control the speeds (exactly) of 3 motors running at 12400rpm or 207 rotations per second. For this, I'm hoping to work with encoders that have 256 counts per revolution. That is, each motor will output 53000 counts per second. That means the teensy will need to read at 53khz for all three motors. In addition to this, I'm hoping to get PID control of each individual motor for it's speed with feedback from the encoders and run the teensy as an SPI slave. Will this be feasable/will it work at a reasonable rate? Will 3 encoder interrupts clash with each other?
thanks,
Brian
