NVS Partition Editor UI for ESP-IDF

Our VS Code Extension comes with UI to creates a binary file based on key-value pairs provided in a CSV file. The resulting binary file is compatible with NVS architecture defined in ESP_IDF Non Volatile Storage. The expected CSV format is:

key,type,encoding,value     <-- column header (must be the first line)
namespace_name,namespace,,  <-- First entry must be of type "namespace"
key1,data,u8,1
key2,file,string,/path/to/file

This is based on ESP-IDF NVS Partition Generator Utility. Make sure idf.espIdfPath configuration setting is defined for this to work properly.

Prerequisites

  • ESP-IDF >=v4.x
  • IDF VSCode extension version >=0.6.0

Steps

  • Press F1 -> Type ESP-IDF: Open NVS Partition Editor (to create a new file) or right click an existing CSV file.
  • If creating a new file, choose the name of the file. It will be created in the current editor directory.
  • Make desire changes to CSV data.
  • Save the CSV data (First time will create the csv file).
  • Generate the partition binary (Choose encrypt to encrypt the binary and disable the generate key option to use your own key if desired).
