Hello,I have the esp8266 Nodemcu v3.
I want to save some integer variable in a JSON file and load them on the setup.
I download the json library, there is an exemple with an SD card, but I don't know how convert it to save and load data.
For exemple if I have :
int variable1 = analogRead(A0);
int variable2 = analogRead(A1);
int variable3 = analogRead(A2);
int variable4 = analogRead(A3);
I want save them in a JSON file on the SPIFFS and load them in the setup().
Who Can Help, tell me what code I need to change, add to do that ?
