void loop () Code language: Arduino ( arduino ) The first argument here is the variable that we want to be sent. Using the radio.write() function we will send that message to the receiver. In the loop section, at the transmitter, we create an array of characters to which we assign the message “Hello World”. Radio.startListening() Code language: Arduino ( arduino ) Radio.stopListening() Code language: Arduino ( arduino ) // at the Receiver Next we have the radio.stopListening() function which sets module as transmitter, and on the other side, we have the radio.startListening() function which sets the module as receiver. Note that if using a higher level it is recommended to use a bypass capacitors across GND and 3.3V of the modules so that they have more stable voltage while operating. tPALevel(RF24_PA_MIN) Code language: Arduino ( arduino ) Then using the tPALevel() function we set the Power Amplifier level, in our case I will set it to minimum as my modules are very close to each other. radio.openReadingPipe( 0, address) Code language: Arduino ( arduino ) On the other side, at the receiver, using the tReadingPipe() function we set the same address and in that way we enable the communication between the two modules. radio.openWritingPipe(address) Code language: Arduino ( arduino ) In the setup section we need to initialize the radio object and using the radio.openWritingPipe() function we set the address of the receiver to which we will send data, the 5 letter string we previously set. We can change the value of this address to any 5 letter string and this enables to choose to which receiver we will talk, so in our case we will have the same address at both the receiver and the transmitter. const byte address = "00001" Code language: Arduino ( arduino ) Next we need to create a byte array which will represent the address, or the so called pipe through which the two modules will communicate. RF24 radio ( 7, 8) // CE, CSN Code language: Arduino ( arduino ) The two arguments here are the CSN and CE pins. So we need to include the basic SPI and the newly installed RF24 libraries and create an RF24 object. } Code language: Arduino ( arduino ) Code Description */ # include # include # include RF24 radio ( 7, 8) // CE, CSN const byte address = "00001" } Code language: Arduino ( arduino ) Receiver Code /* */ # include # include # include RF24 radio ( 7, 8) // CE, CSN const byte address = "00001" * Arduino Wireless Communication Tutorial Here are the two codes for the wireless communication and below is the description of them.

Just search for “rf24” and find and install the one by “TMRh20, Avamander”. We can also install this library directly from the Arduino IDE Library Manager.

Once we connect the NRF24L01 modules to the Arduino boards we are ready to make the codes for both the transmitter and the receiver.įirst we need to download and install the RF24 library which makes the programming less difficult.

While assembly instructions have a 1:1 relationship with machine code instructions, there's still some compilation in the translation process since symbols and data blocks need to have addresses assigned before the CPU can access them - also assembly uses ASCII while machine code is an array of pseudo-arbitrary bytes.Īlso, 'byte code' refers to something vaguely resembling machine code that's used only by interpreters rather than any physical CPU, eg Java or LLVM's intermediary representation.Ĭompilation goes like this: C++ (multiple files) → assembly (with unresolved symbols) → object files (machine code with unresolved symbols) → linking (cross-referencing all the symbols between multiple object files) → flash to target chip (with avrdude or esptool or whatever) Neither actually, OP's code was compiled to machine code. Your code was compiled to byte code (assembly language)
