For the programmable controller based on ESP8266, built-in web page Chinese programming, two digital inputs and two relay outputs, the codes are complete now start to the further optimization as well as reliability testing.
After running the application, the ESP8266 still has about 6K of RAM space left.
Flash space is used as follows:
512kByte is used to store web pages;
256kByte for storing Chinese programs written by users through web pages;
4kByte for storing user configuration data;
4kByte for backing up user configuration data;
4kByte for storing bootloader programs;
1MByte for storing application programs;
1MByte for firmware upgrade;
A total of 2.7MByte of space is required.
The Flash space size of ESP8266-07S is 4MByte, and there is still a lot of Flash space left;
