Harvesting serial data and displaying to an LCD module.

Hi everyone! First of all, please tell me if I'm on wrong thread since I don't know where to ask. Thanks in advance.

I would like to ask guidance and help on a project. I wanted to harvest data from digital blood pressure and display on the seriaan LCD using arduino, then prints the results on a paper using thermal printer.

My problem is, I don't know where to start the program in getting the value from the blood pressure monitor. I have already determine the Clock and data pin of the device.

Hi,

Would it be possible to provide the model number of the monitor device or what kind of interface is uses ?

Regarding the LCD display portion, have you got your code figured out ? Are you able to display information on your LCD ?

Also, would it be possible to provide the Arduino board or Atmega device you are using ?

As it currently stands, not much information has been provided.... :slightly_frowning_face:

One of the examples in Serial Input Basics (probably the second one) may do much of what you need.

It will be easy to adapt it to take data from SoftwareSerial or a different hardware serial port.

What Arduino board are you using ?

...R

I apologize for the lack of informations.

I’m using gizduino ATMega328 (quite similar with arduino uno)

This is the project’s flow:

Blood pressure monitor (after measuring, the values from its display will be read by the board) >> board (get the data (serial data) and apply conversion to display the same values to the software’s serial monitor >> LCD (display the values same on the blood pressure device and serial monitor) >> print (I am using thermal printer)

Here’s the blood pressure monitor I’m using:

Here’s the LCD display of the device, all segments are high:

Yes, I have created my code. And no issue. Also with the printing code. :slight_smile:

I will spend time reading for this thread. Thanks.
