ADC-JN5169

1,503 Views

Hello Community,

I am trying to program the JN5169 Microcontroller so that i can read at first a potentiometer

through one of the 6 ADC channels.

How do i go about writing a simple code for this?

Regards

Matt

Hi Matthew,

Please look at the LcdDriver.c file that you could find in the SDK.

C:\NXP\bstudio_nxp\sdk\JN-SW-4170\Platform\DK4\Source

    vAHI_ApConfigure(E_AHI_AP_REGULATOR_ENABLE,
                 E_AHI_AP_INT_DISABLE,
                 E_AHI_AP_SAMPLE_8,
                 E_AHI_AP_CLOCKDIV_500KHZ,
                 E_AHI_AP_INTREF);

    while (!bAHI_APRegulatorEnabled());   /* spin on reg not enabled */

    vAHI_AdcEnable(E_AHI_ADC_SINGLE_SHOT, E_AHI_AP_INPUT_RANGE_2, E_AHI_ADC_SRC_VOLT);  //enable adc

    vAHI_AdcStartSample();      // start sampling adc

    while(bAHI_AdcPoll());      // keep polling until we get a value

    u16BattVoltage = 0;‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Hope it helps.

Hi Mario,

Thank you for the info.

I have created a *.c file & *.h file based on what i need from the example code you told me to look at. There were a few errors that it brought up but ironed out most of them. There is an error that i seem to not be able to sort out.

Error code: -

symbol(s) not found for architecture x86_64

What does this mean?

Any help much appreciated

Regards

Hi Matthew,

Did you add your c file in the makefile?

For example

###############################################################################
# Application Source files
# Note: Path to source file is found using vpath below, so only .c filename is required

APPSRC = app_main.c‍‍‍‍‍

What is the error that the console log is showing?

Hello Mario,

Thank you for the reply

The error that comes up is in the Problem Tab and it says:-

symbol(s) not found for architecture x86_64.

in the console log tab:-

It doesnt even make a Makefile.

I think i must be doing something wrong or missing something?

Hi Matthew,

Did you include the #include "AppHardwareApi.h" in your c file?

Hi Mario,

Yes i included "AppHardwareAPI.h" in my c file i also incuded:-

#include <jendefs.h>

#include "ADC2.h"

I included the below just to make sure it covered anything that i needed.

#include "AppHardwareApi_JN516x.h"

#include "AppHardwareApi_JN5169.h"

#include "PeripheralRegs.h"

#include "PeripheralRegs_JN516x.h"

#include "PeripheralRegs_JN5169.h"

Could it be down to that i dont have any symbols in the Properties of the project.

I am doing this on a Mac and using Eclipse. i have also done this on a Windows machine using Beyond Studio and that still doesnt put anything in the Symbols tab in properties.

This is the rest of my code: -

Hi Matthew,

The h file should be in your application source folder.

The make file should have defined the c file.

For Example, the ADC2.c file

#include <jendefs.h>
#include "AppHardwareApi.h"
#include "ZTimer.h"
#include "app_main.h"
#include "ADC2.h"‍‍‍‍‍

Makefile

APPSRC = ADC2.c‍

Please let me know your findings.

Mario

HI Mario,

I have my *.h file in the source folder. in my makfile i have defined my *.c file.

I have managed to overcome the error that i was getting. i beleive it was down to the toolchain i was using.

On another note how would i go about coding to print the ADC value out into terminal on Beyond Studio once i have it enabled and also started to ADC sampling?

Want to see the values change from the potentiometer when i alter it left or right.

Regards

Matthew

Hi Matthew,

You could use the DBG Printf function, the first parameter should be TRUE.

    u16ALSResult = u16TSL2550_ReadResult();
    DBG_vPrintf(TRACE_LIGHT_TEMP_OCC_SENSOR,"\nResult = %d",u16ALSResult);‍‍

Hope it helps.

Mario

Hi Mario,

Thank you for the reply. Managed to get the value to print out to terminal.

Thank you for all the help.

May call upon yourself again.
