CCS: CCS ISSUE

Jinwook Jeong1
Prodigy 110 points

Other Parts Discussed in Thread: MSP-EXP430G2ET, RF430FRL152H

Tool/software: Code Composer Studio

JD Crutchfield told me that he recommend to implement the software from http://www.ti.com/tool/DLP-7970ABP 

So I found that file from the web site, and implemented the file on CCS

I want to check ADC value from RF430-TMPSNS-EVM. I connected with TRF-7970ABP with MSP-EXP430G2ET and RF430-TMPSNS-EVM.

But I coudn't check ADC value. How can I check the ADC value from RF430-TMPSNS-EVM?

Thank you in advance

    Hello Jinwook,

    That is not the right software. See Section 1.3 of the FAQ guide which walks you through everything you need software wise and provides links to other collateral: http://www.ti.com/lit/pdf/sloa247

    I use pH sensor with RF430-TMPSNS-EVM  and  TRF-7970ABP with MSP-EXP430G2ET.

    We already checked ADC 0 value thorugh GUI.

    We want to ADC0 value(pH value) thorugh CCS.

    I checked the FAQ 1.3.

    Which one do I have to check? sloc346?

    I tell you for the hundredth time that, I need a CCS code.

    Through the code, I want to check ADC value (not using GUI).

    Thank you in advance.

    Hello Jinwook,

    We do not have an example code that is designed to display the ADC values in CCS but you can use breakpoints and check the register value if that is what you want.

    If you don't want to use our provided GUI then you need to implement your desired functionality on your end, our example is specifically setup to highlight all device functionality through the GUI as a singular platform to allow the best evaluation of the device.

    I use pH sensor with RF430-TMPSNS-EVM  and  TRF-7970ABP with MSP-EXP430G2ET.

    In GUI, Data value shows hexadecimal digit form.

    I want to change this value to decimal.

    I want to change the decimal value to pH value through some specific equation.

    If that, how can I change the hexadecimal value to decimal and specific pH value? 

    Thank you in advance

    Hello Jinwook,

    Depending on the complexity of the calculation, you could do it within the MCU and then just output the value via UART.

    Presuming you would need floating point calculations, you can reference this TI reference code on how to use the IQ Math library to do calculations from ADC values coming from the RF430FRL152H: http://www.ti.com/lit/pdf/sloa233

    The other alternative is sending the data over UART to the PC and making your own GUI to do the calculation and display of the value, which would save on MCU space.

    I want to use the second method you recommend.

    I wonder how to calculate some equations within MCU.

    Do it need code?

    I know that MSP-EXP430G2ET. is one of MCU.

    How can I do calculation through MCU?

    Please let me know the method concretely.

    Thank you in advance

    Hello Jinwook,

    The basic methodology is laid out in the app note. You will need to make a custom calculation for your sensor though. As far as the NFC part goes, I have provided all I can on that front.

    If you have further MSP430 specific questions, then please make a post to the MSP430 forums on the topic about how to use the device to do calculations. I am not an expert to support the MSP430 MCU so the information in the app note is the most I can offer on that front.

    Hello, Jacobi.

    Thank you for your hard work from now.

    You said that the basic methodology is laid out in the app note.

    Where can I find the app note?

    How can I approach the app note?

    Sorry for bothering you.

    Thank you in advance

    Hello Jinwook,

    I linked it in my prior post, it is http://www.ti.com/lit/pdf/sloa233

    Section 6 outlines what needs to be considered for such calculations.
