Receives from software serial, sends to hardware serial.
It is possible to have multiple software serial ports with speeds up to 115200 bps. Receives from the hardware serial, sends to software serial. The SoftwareSerial library has been developed to allow serial communication on other digital pins of the Arduino, using software to replicate the functionality (hence the name 'SoftwareSerial '). I was able to make the library work using the little example from the library, but I started to have some weird characters in the screen at the moment of boot up.
Here will also use an example to demonstrate how to use Software Serial. When using an Arduino there are two common ways to use serial, one uses the actual serial port hardware and the other uses software to emulate serial hardware. The version of SoftwareSerial included in 1.0 and later is based on the NewSoftSerial library by Mikal Hart. The Arduino hardware has the built-in support for Serial communications on pins. A parameter enables inverted signaling for devices which require that protocol. The SoftwareSerial library has been developed to allow serial communication on other digital pins of the Arduino, using software to replicate the functionality (hence the name " SoftwareSerial").
Conclusions Although this is a basic test, it requires more complete tests regarding the configuration of more serial serial ports. This hardware allows the Atmega chip to receive serial communication even while working on other tasks, as long as there room in the 64 byte serial buffer. Test To verify the operation of the softwareserial library, I downloaded the library for esp and I have temporarily replaced the serial software version for arduino. The native serial support happens via a piece of hardware (built into the chip) called a UART. The Arduino hardware has built-in support for serial communication on pins 0 and 1 (which also goes to the computer via the USB connection). Most boards support more than one Serial interface in the Hardware (such as the Arduino Mega), and additionally you can also use the Software Serial Library.
