![]() The rest of the program is just declaring the 2 softwareSerial instances and running this function in the loop + a PID and other sensors, which have nothing to do with softSerial. Here is the function to read the Sonar which switches listen()ing. Note that I kept the same practice transmitter code and I'm supposed to receive 300 every 4 seconds I've tried to make the lapse during which I listen to the SONAR as short as possible, but still half the data I receive is "altered". We wanted to keep the hardware serial for debugging/comm with the computer, so I would need to switch between softwareserial ports to listen to the transmitter Arduino and to listen to the SONAR. However, there is a SONAR sensor in this project that requires serial comm. The objective is to always be listening to another Arduino via softwareSerial, because someone will be able to input data to the receiver through the transmitter Arduino. ![]() Ok now it might be more of a feasibility question, but I've brought this code we just corrected to a real project. Your codes are modified as per Post#1 and executed. Daa from port two:ĭata from port This is the setup of UNO+NANO using Soft UART PortsĢ. Simple ESP8266 <> Arduino Uno Software Serial Integration: Our goal was to create an ESP8266 AT command library (based on the ITEAD library), that would work well on software serial on most ESP8266 devices, provided they have firmware that responds to AT commands (which is usually the manufacturer default).Also, I wonder why they are printed as batches of 3 Data from port two: number, since from what I understand, I should be reading only 2 bytes every 4 seconds. Looks like something's really wrong, I even had a ''Daa'' spelled instead of ''Data'' on the serial monitor as you can see down here. I expected 300 to be printed (value of int info2 on the transmitting Arduino) but I receive a batch of huge numbers every 4 seconds (the low and high bytes of info2 are supposed to be sent only once every 4 seconds). Here is the output on the Serial monitor. * Data receiving on portOne masked until I figure out how to make portTwo work.īyte h = portTwo.read() //read those two bytes back to back! SoftwareSerial portTwo(5, 6) //FONCTIONNNE AVEC LES 2 TX À 9. ![]() put your setup code here, to run once: The Transmitter arduino will send data to both instancesĪnd it needs to listen() to each by turn. The embedded sensors typically communicate data to the controllers or computers. ![]() My transmitter code: /*Test 2 instances with Same TX on the receiver arduino. The software serial ports can communicate data at speeds as high as 115200 bps. I'm at the point where I'm trying to send an int from an Arduino to another as a low and high bytes, but it simply doesn't work They can be found in File → Examples → SoftwareSerial.Hi! I'm working on this code simply for learning how to use SoftwareSerial. You are encouraged to go through the examples that come in with the SoftwareSerial library. Serial.println("Hello World") has the equivalent mySerial.println("Hello World") and so on. Serial.begin(9600) translates to mySerial.begin(9600) The other functions are similar to Serial. SoftwareSerial mySerial(10, 11) // RX, TXĪs you can see, you need to create a SoftwareSerial object using two arguments − the RX pin and the TX pin. Defining the Software Serial is very straightforward. The SoftwareSerial library is included in Arduino IDE Versions 1.0 and above, and you don’t need to install it separately. Other limitations of this library, specific to some Arduino boards, can be found here. Speeds can be up to a maximum of 115200 bps If you are using multiple SoftwareSerial ports, only one can receive data at a time Thus, if you have any other peripheral that requires serial communication, in the absence of SoftwareSerial, you’d have to do away with USB Serial communication. Arduino Uno, for example, has only one HardwareSerial port (pins 0 and 1), which is connected to the USB via the USB to UART conversion chip. The SoftwareSerial library was developed to ensure that any pins of Arduino can exchange Serial data with other peripherals, like GNSS receivers, using software.
