Re: Teensy Up/Down Torch Height Control
I've just forgotten the name of the library but there is some Arduino code that buffers data writes and achieves very fast speeds writing to disk from a memory buffer sa large as you can make. Also, you really should be using an interrupt service routine to poll the voltage. It seems that your frequency library uses one timer interrupt but I think there is another you could use. So let the ISR poll the voltage and the loop can do things at a more leisurely pace. Sorry but I've got too much linuxcnc code running through my head to go back to the arduino to help further.
