Hello everyone.
I am trying to connect an MPG encoder, but it does not work, it does not always count to 0. I connect it to an Arduino Nano in pins 2 and 3 that are the pins with interruptions.
I have modified in the .ino file:
#define Quadencs 1;
Encoder Encoder0 (2,3); // a, b pin
const int quadencsig = {2,2};
const int quadencmp = {4.4};
hello
Thanks for your good work
I had a question
Why don't you use spi communication instead of using serial communication?
In my opinion, more reliable performance can be expected using spi connection
I guess SPI would tie you to an arm platform or trying to bit bang from the host PC.
SPI is not recommended for long distance runs (its only really meant to board comms), even 6 or so inches can be unreliable when approaching MHz speeds. Seen this when experimenting with a Mesa 7c81.
Serial can use differential signals if there is noise, SPI differential signals can play havoc with timing at speeds.
And in reality unless you have a real hardware serial port, the serial comms is USB (at the host PC), doesn't run in realtime......in fact there is no realtime serial driver for Linuxcnc.
