ESP32-UART-programming

In this post, we will see how the ESP32 UART peripheral can be programmed UART stands for Universal Asynchronous Receiver Transmitter ESP32 has 3 UART controllers These controllers are connected to the GPIO matrix allowing you to assign the UART peripherals to any of the GPIO Communication speed is up to 5 Mbps All the 3 UART interfaces can be...

ESP-32 Boot-up Sequence

When We start to learn a microcontroller or SoC, we want to write a lot of code quickly and make use of all the available features/peripherals. But I think acquiring proper knowledge of the boot sequence of an MCU is also very important. I have seen embedded products getting stuck/hung in boot mode. Most of the time the reasons are developers not spending...

Native ESP32 Toolchain Setup

In this post we will set up the Native Compiler and toolchains in our Linux Host machine to program theESP32-DevKitC V4board . After the Setup, we will run 2 example codes We will use the ESP-IDF which stands for Espressif IOT Development Framework. The SDK is built upon freeRTOS. It provides ESP mcu Specific standard APIs so that you can easily...

ESP32-Hardware-Introduction

ESP32 is an amazing chip. in this blog post, I have tried to summarize some important hardware facts that we should keep in mind while designing an embedded product around it. For example, tips to reuse the strapping pins after boot. Hope it helps! 😀Board info The board that I am using is called the ESP32-DevKitC V4 board ESP32-DevkitC v4 board ESP32-WROOM-32...
