Reference SoftwareSerial Library 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). The native serial support happens via a piece of hardware (built into the chip) called a. 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. 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'). It is possible to have multiple software serial ports with speeds up to 115200 bps. A parameter enables inverted signaling for devices which require that protocol.
With a basic example I fail to see results in the serial. Arduino SoftwareSerial library basic example doesn. Your program is trying to setup software serial. AltSoftSerial emulates an additional serial port. (not used for uploading or the Arduino Serial Monitor). Arduino Mega. Yet another alternate software serial.
The version of SoftwareSerial included in 1.0 and later is based on the by Mikal Hart. Limitations The library has the following known limitations: • If using multiple software serial ports, only one can receive data at a time. Games Onet Portable Toilets. • Not all pins on the Mega and Mega 2560 support change interrupts, so only the following can be used for RX: 10, 11, 12, 13, 50, 51, 52, 53, 62, 63, 64, 65, 66, 67, 68, 69 Example.
