Same-Origin policy is used by web browsers to prevent scripts to be able to access remote content if the remote address has not the same origin of the script. This prevents malicious scripts from performing requests to other websites to obtain sensitive data.
The origin of two addresses is considered the same if both URLs have the same protocol, hostname and port.
We may use QML to build hybrid applications, since it's much more easier than C++. So we should know how they communicate with each other.
I2C is a communication protocol that can make two or more Arduino boards talk to each other. The protocol uses two pins - SDA (data line) and SCL (clock line). Those pins are different from one Arduino board type to another, so check the board specification. The I2C protocol set one Arduino board as the master, and all the others as a slave. Each slave has a different address that the programmer set hard-coded. Remark: Make sure all boards connected to the same VCC source
The intent of this topic to demonstrate some basic MIDI programs that show how to operate with the protocol and progressively add useful features that more complex applications require.
This topic is about serial communication using the Universal Asynchronous Receiver/Transmitter (UART) peripheral of the STM32 microcontrollers.
