Is there any way by which i can store uint32 array in spiffs and then read it back into a array?

- Wed Sep 12, 2018 3:03 am #78188 Yup offcourse i know how to write to spiffs. But what is the correct procedure? Write numbers to file line by line

Or

First add the array to json and then save to json to file. And array size can be near to 500 which is a little concerning with ArduinoJSON.
