MSP430G2553: heart beat counter and msp430g2553

Part Number: MSP430G2553

Hi all

I want to make a project with msp430g2553 and heart beat counter(https://www.robotistan.com/pulse-nabiz-olcer) In this project, I need to see the data coming from the sensor on my computer screen.How ı start?


  • Hi Azime,

    I would start with the MSP430G2553 LaunchPad. You can use the +3 or +5v on the LaunchPad to power the sensor and use the MSP430G2553's ADC to measure the sensor's output signal.  There are several G2553 ADC code examples in the TI Resource Explorer.

    To send data to your PC, the LaunchPad has a "back-channel" UART as part of the programming features.  The G2553's UART is already connected to the programer's back-channel UART through some jumpers on the board so all you need to do is configure the UART and GPIO pins.  Refer to the TI Resource Explorer examples on how to use the UART.  The LaunchPad also comes with several example projects and I believe several use the back-channel communications interface as part of the demo.  You can re-use those examples to get started quicker.

    Good luck - this sounds like a cool project :)

  • Hi Dennis

    I will examine the examples you said. Thanks for the information and luck wish:)
