Hi everyone, this blog is to send a data to ThingSpeak server using the STM32 microcontroller. What are AT commands? AT commands are commands which are used to control the modems where AT stands for Attention. These commands were derived from Hayes commands which were used by the Hayes smart modems. Every wireless, as well as the…
Introduction to MATLAB MATLAB is basically a high level language which has many specialized toolboxes for making things easier for us What are we interested in? Matlab is too broad for our purposes in this course. The features we are going to require is Matlab Screen
Overview This chapter describes the features and operation of the serial communication interface (SCI) module. SCI is a two−wire asynchronous serial port, commonly known as a UART. The SCI modules support digital communications between the CPU and other asynchronous peripherals that use the standard non-return to zero (NRZ) format. The SCI receiver and transmitter each…
Overview We will learn everything we need to know about using an Arduino to operate stepper motors in this lesson. We’ll go over how to use an M415B and a TMC2208 stepper driver to control a NEMA17 stepper motor. Numerous devices like 3D printers, CNC machines, robots, automation machines, and others that require position control use…
Overview communication between the MCU controller and external peripherals or another controller. Typical applications include external I/O or peripheral expansion with devices such as shift registers, display controllers, and analog-to-digital converters (ADCs). Communication between multiple devices is supported in SPI master or slave mode. The port supports 16-level receive and transmits FIFOs to reduce CPU…
Overview Inventor of the MIT APP Arduino Bluetooth application. I have used Bluetooth mobile phone applications to monitor and control various types of sensors and electrical loads. I developed all my previous apps in Android Studio. A few months ago I uploaded articles on how to develop a custom Android app to control electrical loads…
Overview In today’s lesson, we will learn how to connect the keyboard to the Arduino. In embedded devices, one of the essential parts is the keyboard, which is used to interact with embedded devices, the keyboard is an input device used to give commands to other devices, from the calculator to the computer; keyboard input,…
Program STM32F4 with UART STM32F3 devices have a great feature. They can be programmed with the only USB to UART converter. Each device has a bootloader inside, which supports UART programming. This is not a very great method for Discovery boards, because they have a better and faster solution onboard, ST-link. But if you are…
Overview Today people drive very fast. Accidents happen so often that we lost our precious life by making small Driving errors (school area, hill area, roads). Therefore, to avoid this type of accident and alert drivers and control the speed of their cars in these types of places, the Highway Administration has made posters. But…
Over view This project describes connecting a Slamtech RPLIDAR A1 directly to an Arduino using its in-built serial port. So no need to use the supplied USB interface. DESCRIPTION RPLiDAR A1M8 360 Degree Laser Range Finder – 6m (Radius Range) is a low-cost 360-degree 2D laser scanner (LIDAR) solution developed by SLAMTEC. The system can perform a 360-degree scan within…
