Part Number: MSP430FR2355

Hello

I am working whit MSP430FR2355 Lunch pad and using Code Composer Studio 10.3.1.

I want to have DAC as input and then give output of DAC to ADC and to display output of ADC on LCD

Know I have some problem:

1- Do you have example code to have DAC input and ADC as output?

2- Is there any software or schematic environment that I can simulate and test my code to see result before using Micro?

3- Do you have something like project wizard to produce code according to schematics?

Best Regards

Hi Hadi,

I am sorry for don't understand your requirement.

You need generate a voltage via DAC? and capture this voltage via ADC?

There are some example code as your reference:

Thanks!

Best Regards

Hello,

Yes, Exactly, I would like to create a voltage with DAC and to capture this voltage with ADC.I would be so appreciate if you kindly can send me example code for this work as I couldn't find it in the link . Also If it is possible let me know if there is schematic software that I can test code before execute on MCU.

Hi Hadi,

We provide some examplde code in the pervious link:

https://dev.ti.com/tirex/explore/node?node=ANb170XIJpeepYK6GrY-ew__IOGqZri__LATEST

And for applicaiton code maybe need you to implement using those example.

And maybe this application note is useful for you:

Hi Johnson

Thanks for replay.

My problem in ADC and DAC was solved. Thanks a lot.

Know I have a ADC digit and I want to display on LCC (Sharp128),

My ADC output, is in

unsigned int ADC_Result;

I used this query for display on LCD, but I have some error.

GrStringDrawCentered(&g_sContext, " my ADC Value" <<ADC_Result , AUTO_STRING_LENGTH, 65, 20,TRANSPARENT_TEXT);

My error is: #31 expression must have integral type

Best Regards

Hadi

Are you using C or C++? It looks like the << does not have the C++ overload.

Hi
I am using C.

My problem was not solved. I want display (string + int) in this query.

unsigned int ADC_Result;

I used this query for display on LCD, but I have some error.

GrStringDrawCentered(&g_sContext, " my ADC Value" <<ADC_Result , AUTO_STRING_LENGTH, 65, 20,TRANSPARENT_TEXT);

I understand that, but << is a shift operator in C.

Try including stdio.h and use sprintf() with a separate buffer:

char buffer[32]

sprintf(buffer, "My ADC Value: %d", ADC_Result);

GRStringDrawCentered(&g_sContext, buffer....

I couldn't understand your answer. Can you explain it completely to me and to write complete code .Thanks alot

#include <stdio.h>

int main()
{
    char buff[32];

    uint16_t data;

    // Read ADC
    sprintf(buff. "ADC Value = %ud", data);
    GrStringDrawCentered(&g_sContext,buff, AUTO_STRING_LENGTH, 65, 20, TRANSPARENT_TEXT);
}

Not that hard, really. You used a C++ construct - the overloaded << operator - in what appears to be pure C code. You need to use C, which means using stdio.h and sprintf(). Any C resource should show you how this code works.
