MSP430FR2311: Printing Pin Value to Console/Screen

D_J

Part Number: MSP430FR2311
Other Parts Discussed in Thread: MSP-EXP430FR2311, ENERGIA

Hi,

I've very new to embedded systems and especially the MSP430 (I'm a coop student and have only worked with arduino before). I was hoping someone can help me print the value of the A5 (P1.5) pin to console. I am trying to set up the TIA and would like to see if I am getting the results I expected.

What I thought to do was set the pin to a variable and then print the variable using printf(). Is this a good way to approach? Also, how do I declare the pin (P1.5)? I've tried looking online but haven't found anything concrete.

Any help is much appreciated!

Hi Diana,

If you are familiar with arduino then I suggest you look into the Energia IDE, support for the MSP-EXP430FR2311 is coming soon.

Meanwhile you can set up a backchannel UART communication peripheral to output analog values to a terminal. Getting started ADC10 & UART code examples are provided by TI on the product's tools & software page: www.ti.com/.../slac708

If you want to see the actual decimal value on your terminal then the most difficult part will be converting the integer value into separate characters so that each numeric representation can be sent by the UART buffer individually (one byte at a time).

You could also just view the analog conversion results inside of your debugger or use the printf function from the CCS compiler:

Thanks Ryan! Yes, I've been waiting for Energia... Hopefully soon! I've taken the UART approach as you suggested. Thank you.
