SPIFFS mod resize for ESP8266.
In the project "Arduino core for ESP8266 WiFi chip" used to manage and program the boards with the ESP8266 chip from the Arduino IDE, by replacing the files of this repository will add more options for flash memory partitioning.
The idea arose from the need to adapt the flash memory of my modules to the needs of the projects.
The project with which that need was born was McLighting that allows controlling an RGB LED strip WS2812B which gave storage problems in the compilation in a module ESP8266 ESP-01. The Sketch was too large for the reserved space of the default memory by the plate library (512KB - 64KB (SPIFFS) = 448KB Total for Sketch). An arrangement could be to dispense with some program feature but limited its functionality.
So I came up with the modification of the file system to be smaller (32KB) and thus have 480KB for Sketch. After a couple of days with the hexadecimal calculator I managed to work and compile and upload the sketch without problems.
Now the problem would come in that only have 32KB of memory for data as a Web page. But in my case more than enough.
- Clone the repository on your Desktop.
- Access the following directory on your PC. In Windows:
"C:\Users\USERNAME\AppData\Local\Arduino15\packages". - Copy
".\Esp8266\*.*"And replace. - Start in IDE Arduino and you can already select from the menu
"Tools"the 'Size of the Flash` you need.
