    I have firmware for an ESP32 device written for PlatformIO (basically arduino), but it has become very long and messy. I need help removing any redundant functions that are not being used, and creating a library with all the remaining functions. This will alllow the file to be less cluttered as it will call its functions from the library file. The ESP32 firmware controls a device with an ADXL accelerometer, an optional GPS unit, ethernet or wifi connectivity, LEDs and a buzzer. After starting up its peripheral devices it checks if ethernet is connected, if not it uses Wifi with Smartconfig protocol, then connects to AWS. This is done using AWS certificates stored in the SPIFFS memory. Once connected to AWS it collects the ADXL FIFO buffer of accelerations every second and sends them t...

Il software dovrà prevedere la lettura di card rfid e inviare i dati della card ad un server. I dati sono riferiti ad articoli da ordinare semplicemente avvicinando la card, ogni card corrisponde ad un articolo. Il software dovrà inoltre dare la possibilità di inserire la quantità ordinata dopo la lettura della card e vari messaggi di conferma o errore. Dal lato server i dati dovranno essere ordinati per cliente, articolo, quantità (dati presenti in ogni card) Lo spunto lo prendiamo da questo progetto pubblicato :
