We have connected to existing network using ESP32, we have sent messages to a TCP server running on different machine in our network. Now it is time for

I recently bought  blue pill board (STM32F103C8T6) from ebay , this is a inexpensive STM32 board. We can actually use Arduino IDE to program these boards. In this

There is no fun in IoT without a network connection. Lets connect our ESP32 to a WiFi access point. In this post we will connect to given SSID

In the context of multi processing, task synchronization is very important concept. In this post we will see how to use event groups for task synchronization Task Synchronization

In the previous post we have seen how to create task , in this post we will see how to use queues to share data between two tasks.

In this blog we will see how to create a FreeRTOS task on ESP32 , we will also see how to load the code using just MINGW command

In this post we will see how to run a hello world program using ESP 32. ESP 32 is new chip from Espressif , the same company behind ESP8266. Espressif

I have written many blogs on NodeMCU , but SD card example was missing. in this blog we will see how to mount SD card in NodeMCU filesystem,

In the previous blog we have see how to setup arduino to work with esp32, that was fairly easy, in this blog we will see how to setup
