ESP8266 NONOS SDK SprintF stright from Flash

Well this weekend turned out wonderful. I manage to finish this little piece of and this solution saved me a HUGE mount of heap space. This function I wrote to cycle through flash memory and format SprintF on the fly from Flash memory instead of having to double buffer the formatted HTML page. In my case my HTML page is around 4-8k depending on what I am loading, thats over half the ESP’s heapspace just to send results to the client, YIKES! Now those day’s are over 🙂
