Programming microcontrollers *

This article will tell you how to launch analysis of an embedded project and how to work with the analyzer's report. The PVS-Studio analyzer supports a number of compilers for embedded systems. The current version allows checking projects built with one of the following compilers under Window, Linux, and macOS:

• IAR Embedded Workbench
• Keil Embedded Development Tools for Arm
• TI ARM Code Generation Tools
• GNU Embedded Toolchain

NodeMCU is an interactive firmware, which allows running Lua interpreter on the ESP8266 microcontroller (ESP32 support is in development). Alongside with all the regular hardware interfaces, it has WiFi module and SPIFFS file system.

This article describes the new module for the NodeMCU — sdm. SDM stands for simple driver model and it provides device-driver model abstraction for the system. In the first part of this article we will discuss the model itself and in the second part will be a showcase of dynamically created web user interface using sdm with some commentaries.

Let’s find out how to make a simple enough laser projector out of electronics you can find at home.

Introduction

As first-year students of Innopolis University, we had an opportunity to make our own project in computer architecture. University suggested us several projects and we have chosen to make a stack-based calculator with reverse polish notation. One of the requirements for the project is to use FPGA board provided by the university.



As our board, we have chosen Cyclon IV. Therefore, we had to write code on hardware description language. In the course we have studied Verilog, so we have chosen it. Also, the university has additional modules for FPGA, such as numpad, thus we decided to use it in our project.

In this article, we want to share our knowledge about FPGA and Verilog, also provide you with a tutorial to repeat our project.
