After working a lot with 8-bit microcontrollers and learning all the protocols and functions they offer, now I thought to switch to 32-bit microcontrollers. I decided to go with arm 32-bit processors, because of their popularity in the market. I choose the arm cortex-m3 processor series for my new hobby/learning projects. The reason behind choosing…
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…
Overview Texas Instruments produces the well-liked TMS320F28069 microcontroller, which is renowned for its adaptability and capabilities in a wide range of applications, including motor control and power electronics. The Enhanced Pulse Width Modulation (ePWM) module, which provides fine control over PWM signals, is one of its primary characteristics. In this article, we will examine the…
In this tutorial, I want to show you how to flash the code using a mobile phone application. Nearly every embedded system needs the ability to have its firmware updated in the field to add new features or fix bugs. However, firmware field updates can be challenging as a developer must either program their bootloader…
Overview In this post, we will learn how to make a Call & SMS using GSM Module & Arduino. This is a Simple Homemade Phone using GSM Module and Arduino. This simple phone is capable of calling another number as well as receiving an incoming call. Similarly, it can also be used to send an…
Hi guys this article is to discuss the Lora module interfacing with the STM32F blue pill board. The driver is implemented to transmit and receive the data between two devices in Keil IDE using the HAL driver. This library mostly focuses on the Lora mode and uses SPI communication. In Lora mode, we can access…
