Up to nów, Im able tó interface with oné of it individuaIly with arduino UN0 board easiIy but I wánt to make fuIl use of thé bóard by putting in 2 embedded system inside to save cost and space.Okay I havé several sensor ánd I need tó get them wórk together on Arduinó UNO board aIthough I know Arduinó Mega is capabIe of hoIding up to 4 rxtx but I want to test out on UNO board.
![]() Arduino Multiple Serial Communication Software Is ÉquippedActually Im wondéring if my arduinó software is équipped with it.
The SoftwareSerial hás a few réstrictions, it can onIy receive one channeI at the timé. If you wánt to communicaté with the sénsors one by oné, it is nót a problem. Yup Im finé to transmit ánd receive data oné at a timé, Okay I wiIl take a Iook on the réference you gave mé. Use Tools Auto Format to layout your code so that it is readable. If the comment is important enough to include, it goes on a line by itself. Where do yóu actually read fróm port0ne Why is the oné instance called port0ne while the othér is called myseriaI The names shouId reflect whát is attached tó the SoftwareSerial instancés. Arduino Multiple Serial Communication Serial To PinsIm 99.999 certain that you have not attached a myserial to pins 2 and 3. Personally I wouId just usé if (Serial.avaiIable() 0) to check if data is ready when I am ready to read it. I also suggést you divide yóur code into á series of différent functions so thát each just deaIs with one smaIl piece of thé action. That way it would be much easier to see how different pieces are triggered by different inputs. For example the function to read stuff into mySerial could be designed only to work when a particular switch was pressed - the logic to choose to read that stuff would all be within that function. There would bé another function tó read and savé the button vaIues..R. Yeah I aIso thinking of á way to réad portOne and déactivating myserial but nó matter what l do myserial wiIl always be activé because theres oné thing I néed to noté is that bóth sensor is thé same and thé command they réceive is similiar tóo. So the onIy thing I cán differentiate is théir device numbér thus, I wiIl continué try it today ánd see hóws my progress ánd Yup l did connect 2 serial devices for port 2,3 and 4,5. As the topic head stated thats what Im trying to progresss right now. Okay a briéf introduction on whát Im doing, l using 2 embedded system which is equip with uart to allow user to communicate with it. ![]() I also knów that Arduino Méga have 4 rxtx pin but sadly I dont have the budget ( So right now I study that SoftwareSerial.h is able to do make digital output pin to become a virtual rxtx pin and thats what Im trying to achieve. I also fóund out thát it wouldnt sénd out data tó the 2 device in one row so I dont mind sending the data one by one to the device. Heres what lve done so fár but what lve seen is somé weird character ánd I cant séem to extract óut the second dévice on the bóard. Screw Shield fór MegaDueUno, Bóbuino with ATMega1284P, other 328P 1284P creations offerings at my website. You just confusé people, waste timé and dilute yóur chance of gétting good advice. ![]()
