I must have the possibility of using serial communication both at the hardware level and via the software by reversing the protocol, which can be selected simply by software in the firmware. Now I need to flip the logic of serial communication (the whole protocol, not just the transmitted data) and I don't want to do it with external hardware (it would be simple), and only with this library can I do it. I can't change anything regarding connections. In short, I have a device I built based on the ATMEGA 1284P where I use UART Serial1 at the Hardware level. My software that leverages the current serialportĪ little long to explain. MySerial = getNextSoftwareSerial(currSerial) SoftwareSerial* getNextSoftwareSerial(int8_t currSerial) Sample code provided for your pleasure #include Am I not disposing of this object properly? Should I be switching my TX? I've even tried using many different RX pins in the list found here to no avail. Is there something I'm missing? I'm adhering to the RX pin restrictions. I destroy the software serial object once I am finished using it and create the new software serial object for the next IO I want to communicate with. My pins I am trying to use are working, working, non-working, non-working. I was trying to send data from the Arduino Mega board to the NodeMcu and found issues in the program. Im a newbie coder who trying some programming to improve my skills and do projects. I've confirmed that the device works when plugged into. Serial communication between Arduino Mega 2560 & NodeMCU. I currently have two ports working at their respective times, but when I try to use the third it does not work. the ports are not running at the same time, I am using one, destroying it then using the next. wait for serial port to connect.Have an Arduino mega 2560 and require the use of 4 software serial ports, I'm unable to use hardware serial without major refacoring of my hardware/software. Open serial communications and wait for port to open: SoftwareSerial mySerial ( 10, 11 ) // RX, TX This example code is in the public domain. Not all pins on the Leonardo support change interrupts,Ĩ, 9, 10, 11, 14 (MISO), 15 (SCK), 16 (MOSI). Not all pins on the Mega and Mega 2560 support change interrupts, * TX is digital pin 11 (connect to RX of other device) * RX is digital pin 10 (connect to TX of other device) Receives from software serial, sends to hardware serial. Receives from the hardware serial, sends to software serial.
