# In questo schema grafico e' inserita la partizione ota_1 che viene utilizzata come backup della

#
# La dimensione dello spazio e' la differenza degli offset di due partizioni adiacenti, ad esempio lo spazio di ota_0 e' la
# differenza tra gli offset di ota_1-ota

Per caricare una configurazione e' necessario salvarla in un file con estensione cvs e utilizzare la direttiva board_{build.partitions} del file di configurazione di platformio.ini, ad esempio se la configurazione e memorizzata nel file default_FS.csv un esempio di platformio.ini

; PlatformIO Project Configuration File
;
;   Build options: build flags, source filter
;   Upload options: custom upload port, speed and extra flags
;   Library options: dependencies, extra library storages
