I want to interface an external ADC (ADS1231 24-bit) with MSP430F6736 to read analog data and display it on a screen (monitor).
I have a MSP-FET (Flash Emulation Tool) and a MSP-TS430PZ100B 100 pin target board.
I want to read analog data (voltage) and display it on the screen.
What steps do I need to follow?

Thank you.

 

Just a thought, but there are parts out there, UPs, that have hi res onchip
A/D (20 bit) + Reference + ARM core + lots of other stuff like LCD interface -




Note A/D has differential input to handle bridge sensors.

What is the screen ? PC or LCD ?

In general your processor has to implement the two wire interface to A/D,
and then if PC is display device some code, like Python, to display the
data. If specifc LCD incorporate a library in code base to handle it.

Hey Dana,
The screen is a PC.
Will I be able to generate a text file or an excel file to record the data using C?

 

The MSP430F6736 already has an 8-channel 10-bit 200ksps ADC and a 24-bit sigma-delta ADC.
Why do you need an external ADC?

this is an experiment and I want to try interfacing an external ADC.

 

You can use this software by communicating data to it to do basic graphing
and logging -

Look at all vendors very carefully at end to end signal path errors,
not all A/Ds and G elements are equal in their inaccuracy specs.

PSRR, T, Power, Noise, non linearity.......

Attached a basic ap note on error sources, Analog Devices has many
other sources of discussion on this topic.

Thanks Dana.
I'll look into the material and get back to you if I've any further doubts.

Thanks again.

 

Hi Dana,

I have moved on from interfacing external ADCs to using the internal ADCs for conversion process.
I have finished the coding for it but I am stuck on storing/exporting the data to an excel sheet.

Could you help me out with a way to export the data into an excel sheet?

Thanks,
Keval​

 

Here is a way of getting data out over standard links -
