Hi,
I'm new to Arduino and I'm learning how it works, especially the Arduino + ESP8266 version 13 shield I bought as part of a robot car kit from Osooyo.
I have a very basic question;-
How do the 2 microcontrollers (Arduino + ESP2866 version 13) get programmed together via 1 USB connection to the Arduino IDE ?. Each has flash memory, what decides which memory the USB data goes into ?
I'm trying to understand the basic method;-
Do the 2 devices read the same sequence of USB data ?
or
Does all the USB data go to the Arduino , and that microcontroller later program the ESP8266 ?
I'm trying to understand the basic method. I guess my question applies to any Arduino+intelligent shield.
Many Thanks
