Actually I tried working on the altsoftserial library and was successfully able to compile the code but now I wish to connect a 4D systems uLCD 43PT for display which work on 9600 baud rate . Also when I try compiling the code using the display libraries the display the output is shown as in picture attached.
also when the plot starts on the display the sensor starts to give absurd values in serial monitor can you please let me know the reason for it
I still don't see the need for a software emulation. Do you want to add two displays? If it's just one display, just re-use the hardware serial interface.
You might have to tell us what kind of absurd values you get. Post the values you get and post the code you used for that. Eliminate everything that's not needed.
I need the software serial as I have one sensor working at 115200 baud rate and one LCD working at 9600 baud rate
Which sensor is accessed at 115200 baud? The only sensor you mentioned already is accessed by I2C and not a UART style serial interface.
Yes,I agree The mentioned sensor uses I2C communication. But I wanted know,hope you don't mind sharing,if what difference the does it makes on communication with arduino.
Please post the code that produces correct values and also the code that produces the above values. Please use code tags, that's the </> button in the editor.
