I was working on a code where I used PROGMEM storage. I can see there is a function called pgm_read_data to read data of a PROGMEM storage but since I want to store and manipulate data as well, I need to write on data too. I thought there might be a function such as pgm_write_data but apparently the PROGMEM data can only be readable!
so how you guys recommend me to store big data and manipulate them?
all answers are appreciated!
thanks guys for your help
