Buildroot and Qemu (1)

In this story, we will run a Linux distribution using QEMU(https://wiki.qemu.org) First we will need to obtain an iso image of the Linux distro that we will run in the virtual machine. In this example we will use Ubuntu 20.10 which you can find in this link(https://ubuntu.com/download/desktop) After completion of…

By using random inputs to solve problems, the Monte Carlo method has a wide variety of applications. The presented implementation is using the C programming language to approximate the value of π(pi). Imagine a square circumscribed about a circle, and by using a function that sends an input at a…

SPI stands for Serial Peripheral Interface and it is commonly used among micro-controllers and small peripheral devices(for example SD cards, sensors, or shift registers) to communicate with each other. Asynchronous serial ports( a common serial port with Tx and Rx lines) doesn’t offer any guarantee that both sides are running…

vatiCAN is an automotive protocol for secure message exchanges as described in the paper : http://www.automotive-security.net/vatican/ Intending to simulate the behavior of a secure message exchange in omnetpp(Omnet++) , first it would be appropriate to setup a bus environment, since vatiCAN protocol works in the CAN Bus. In the present…

The problem’s definition is that given the initial and final time, and also initial and final positions in an one DOF(degree of freedom) robot, one is asked to move it in a smooth way from initial to final position. Using a cubic polynomial will make it for describing the position…

‘An Arm programming example combined with C programming in an embedded device’ In this article , we are attempting to write and execute code for {Versatilepb/arm926ej-s } in a native Ubuntu OS system, by cross-compiling the code and emulating the execution using the QuickEmulator(QEMU) Code can be found in my Github Arm_Generic repository, here: https://github.com/NikosMouzakitis/Arm_generic/tree/master/10

The creation of Vesica Piscis, consists of having two points in the 2-dimentional space first, A and B. They both can make a full rotation each on another( i.e A as center and AB as diameter and vice-versa). In the following figure we inspect the created shape so far. We…

Creation of a simple kernel module; that will create a new device on the /proc file-system and just the basic operations of read/write are to be introduced. In the first place we will inspect the code for the kernel module that will be called mine.c

We will be simulating three nodes connected in series, where the rightmost node(sender) wants to transmit data across to the leftmost one(receiver). Messages will be crossing the middle node that will act as a bridge between the other two nodes and will route each message in the appropriate output interface…
