Arduino Software Update Introduces Command-Line Tool, Serial Data Plotter

Yesterday’s update to the Arduino IDE software offers Arduino fans a new tool to play with. Version 1.6.6 of the software can be downloaded for free (though donations are encouraged) directly from Arduino.cc. Though, with hourly builds underway, you may want to wait a day or so for any kinks to be ironed out.

What is the difference between i386, i486, i586, i686, i786

Ever wondered what are those words i386/i486/i586/i686/i786 that comes after the name of RPM / DEB packages?

When it comes to understanding the compatibility of a package between different architectures, knowing these terms become important. The above coined terms are Processor architectures. Let’s have a look below…

i386     –     Intel i386/80386   (in 1985)          or          AMD386 / AM386 (in 1991)

i486     –     Intel i486/80486   (in 1989)          or          AMD486 / AM486 (in 1993)

i586     –     Intel Pentium         (in 1993)          or          AMD-K5 (in 1996)

i686     –     Intel Pentium Pro (in 1995)          or          AMD-K6 (in 1997)

i786     –     Intel Pentium 4      (in 2000)          or          AMD-K7 (in 1999)

Linux Kernel 4.3 Stable Released With Improvements, Install/upgrade in Ubuntu/Linux Mint Or Other Derivatives

Picture

Linus Torvalds announced the stable release of Linux Kernel 4.3, the kernel includes some unique things including 20.6 million lines of code. It’s amazing development. The million lines of code was contributed by several companies including, Red Hat and Intel. Linux Kernel 4.3 has some impressive changes and improvements and to be seen in coming distros releases.

The million of lines of code mostly provide the Linux kernel 4.3 more driver support and support for Intel’s latest 6th Generation Skylake processors. Look at the entire

But one thing that all of us are waiting is the Linux Kernel 4.4, recently announced that Linux kernel 4.4 would be an LTS (Long Term Support) release. The first time any kernel has been announced LTS before its release and also there will be more changes and improvements in the Linux Kernel 4.4 LTS.

Move 4 Stepper Motors Synchronously

.

Part of the machine inside FreeCAD

This is the algorithm that plans the trajectory and syncs the movements of the stepper motors, in the new CNC machine that I’m designing (and building!)

The input is an int array { MA, MB, MC, MD } where each int means the number of steps (positive or negative).

The stepper movement logic is stored into a boolean[8] array { SA, DA, SB, DB…. } where SA means step for motor A and DA is the direction bit of the motor A (for a 2 wire stepper driver, like the a4988). This array is erased and re-computed every loop cycle with the next movement, so real motor stepping has to take place inside this loop.

The image below (created with FreeCAD) shows a representation of the algorithm output for a requested movement of ( 5, 15, 25, 40 ) steps. Continue reading Move 4 Stepper Motors Synchronously
