ESP32 COOKBOOK: ESP8266, Arduino Coding, Example Code, IoT Project, Sensors, Esp32 Startup

So we talk about ESB 32 and ESB a 2 6 6. These are system on chips Associates provided by the fabulous semiconductor expressive from China. They are so low cost to use they consist of the Wi-Fi and the dual-mode Bluetooth classic and Beasley and allows us to build Internet of Things applications. I wrote the applications in a very cheap manner. These are both out of less than 10 dollars in cost so they're very cheap and they're very easy to bring up and write applications on. So again as I mentioned designed by the Chinese fabulous semiconductor company called expressive fabulous means that they just create the chip design and other companies take these chip designs on paper and manufacture the silicon right. So what is great about this is that it's very cheap. It has a very simple cedar link to control the MCU and passes 80 commands to control the MCU to sort of start and stop communications to connect to Wi-Fi and so on. So it's very easy to use and very cheap for us to build out the applications. So talking about the ESB 8 2 6 6 hardware it's built with the one CPO which is the 32-bit risk microprocessor L1 0 6. It has 32 kilobytes of instruction ram it has some user data RAM as I mentioned here 80 kilobytes. It has an SBA-based flash you can go up to 16 15 megabytes bunch of GPI opens allows us to connect LCD and other sensors to it and other things on this list in terms of RAM it has 160 kilobytes of the ram of it. We have 64 kilobytes of instruction RAM and 96 kilobytes of data Ram. You can be going to store in the data the item of 64 kilobytes for the partition into two blocks of 32 kilobytes. One is for the ram that the program uses another is the cache which is the cache from the flash memory so when you write a sketch and as the code executes and finds out that that piece of code is in the flash it sort of catches that piece of code from the flash into this piece of RAM and executes from the RAM.
