Jun 12, 2024 · I found this thread while searching for answers to my very similar problem. I had an UNO R4 Wifi using a total of 3 serial ports: Serial for programming and debugging, Serial1 to talk to a UART water flow sensor at 2400 8E1 (settings hard coded in the sensor- ScioSense UFM-01) and a software serial port going to an RS-232 converter for communicating with upstream data gathering equipment.
Apr 8, 2024 · I have been using an Arduino MEGA to communicate with an inverter using the hardware Serial with no problem. I'm trying the same code on an UNO R4, however, I can't use the hardware Serial as I need to read the Serial output , so I'm trying Software serial. However, I get a NAKKS response from the inverter so I wondered if there is a difference between what the Software Serial and Hardware Serial would output? Here is the Arduino UNO code: #include <SoftwareSerial.h> SoftwareSerial mySerial(1...

Sep 24, 2021 · The reason why the SAMD21 boards don't have Software Serial support, is because it's possible to configure the microcontroller's unused and spare SERCOM (Serial Communication) modules, to be either an additional hardware: Serial, SPI or I2C ports.
Aug 3, 2015 · Does software serial really work reliably at 115200 baud? I need to have 2 serial devices attached at 115200 and cannot get software serial to work reliably. I wrote a sketch to simply echo what was received and at 115200 I get ~0.2% of characters being echoed incorrectly. It works fine with 0% errors at 57600, but I really need 115200. I jumped inside the software serial library and found this, amongst the code // When the start bit occurs, there are 3 or 4 cycles before the // inter...
Apr 12, 2013 · I'm happy to announce ArduinoDroid - Arduino IDE for Android. Features: open/edit arduino sketches; example sketches and libraries included; code syntax highlighting; compile sketches (no root required) upload sketches (FTDI-based board and Arduino Uno are supported at this time only, android devices with USB-host support required)
Jan 13, 2021 · Hi, I am having trouble adding 2-3 software serial ports to my Arduino Uno software. Searching this site but also googling globally, i found not consistent info like: "SoftwareSerial can have multiple instances, on any 2 pins" vs "rx pin can be only 2 or 3 because these are the only interrupt capable pins". I gave up searching and did some experimenting instead, with the following results: -regardless of what the documentation says, only 1 instance of SoftwareSerial works (but there is an exa...
May 13, 2014 · Yes you can use software serial on a Uno. As far as I know, any digital pin can be used, but I would not use pins 0 or 1 as they are the hardware serial pins. UKHeliBob May 13, 2014, 3:21pm
