esp32 and esp8266: FAT filesystem on external SPI flash memory
In this article, we are going to integrate into our ESP32 or esp8266 an external flash memory in addition to the internal one.

In this article, we are going to explore the power modes of BON055 and focus on accelerometer features and management.
Whoever has started to peek into the wonderful world of small electronics will undoubtedly have read about Raspberry Pi or Arduino boards. This is where I personally started to ask myself, what is the right board for which project?
In this article, we are going to explore all features of BON055 and how to configure It.
This is the second article on bno055. If you need basic management, you can refer to the previous article “BNO055 accelerometer, gyroscope, magnetometer, and orientation software”, but if you need advanced management (and more complex) with interrupt, you must read this article also.
We are going to discover BNO055, a triaxial accelerometer, a triaxial gyroscope, and a triaxial geomagnetic sensor with a 32-bit cortex M0+ microcontroller in a single package.
In this first chapter, we start a basic usage.
The sensor GY-273 QMC5883L clone HMC5883L magnetometer for Arduino, esp8266, and esp32 is cheap and reasonably precise but needs some check for the clone version.
The ADXL345 is a small, thin, ultralow power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16 g. This device works with i2c and SPI protocol and Is suitable with Arduino, esp8266, stm32, and esp32.
I must fill a tank 1.5 km away, so I create a 2-part controller.
A server with a relay to manage the pump and a client solar/battery-powered to check the tank’s status and notify to the server.
Now we put all the Client components in the relative Case.
