Analog voltage comparator not working on i.MXRT1062

I am trying to compare voltages using comparator 1 and 2 for the power inputs GPIO_AD_B1_02 (usb) & GPIO_AD_B1_03 (board) on my i.MXRT1062 hardware. It is not working. I am using continuous mode. I'm powering the device from both the power inputs. When I remove one of the power inputs, I'm expecting the interrupt to be hit, but it is not hitting.

 

CMP1

#define DEMO_CMP_BASE CMP1

#define DEMO_CMP_USER_CHANNEL 3U

#define DEMO_CMP_DAC_CHANNEL 7U

#define DEMO_CMP_IRQ_ID ACMP1_IRQn

#define DEMO_CMP_IRQ_HANDLER_FUNC ACMP1_IRQHandler

 

mCmpDacConfigStruct.referenceVoltageSource = kCMP_VrefSourceVin2; /* VCC. */

mCmpDacConfigStruct.DACValue = 32U;                                /* Half voltage of logic high level. */

 

CMP2

#define DEMO_CMP_BASE CMP2

#define DEMO_CMP_USER_CHANNEL 3U

#define DEMO_CMP_DAC_CHANNEL 7U

#define DEMO_CMP_IRQ_ID ACMP2_IRQn

#define DEMO_CMP_IRQ_HANDLER_FUNC ACMP2_IRQHandler

 

mCmpDacConfigStruct.referenceVoltageSource = kCMP_VrefSourceVin1; /* VCC. */

mCmpDacConfigStruct.DACValue = 32U;                                /* Half voltage of logic high level. */

Hi robit ballurgi,

   Today, I test the GPIO_AD_B1_02 on my side, it works OK, I use the SDK code, the board is the RT1060-EVKB.

The SDK code project folder is:

SDK_2.5.0_EVK-MIMXRT1060\boards\evkmimxrt1060\driver_examples\cmp\interrupt\iar

Now, just take GPIO_AD_B1_02, CMP1, channel 3 as an example, the modify point:

1. pin_mux.c, add these code:

  IOMUXC_SetPinMux(
      IOMUXC_GPIO_AD_B1_02_GPIO1_IO18,        /* GPIO_AD_B1_01 is configured as GPIO1_IO17 */
      0U);                                    /* Software Input On Field: Input Path is determined by functionality */
    
  IOMUXC_SetPinConfig(
      IOMUXC_GPIO_AD_B1_02_GPIO1_IO18,        /* GPIO_AD_B1_01 PAD functional properties : */
      0x10B0u);                               /* Slew Rate Field: Slow Slew Rate
                                                 Drive Strength Field: R0/6
                                                 Speed Field: medium(100MHz)
                                                 Open Drain Enable Field: Open Drain Disabled
                                                 Pull / Keep Enable Field: Pull/Keeper Enabled
                                                 Pull / Keep Select Field: Keeper
                                                 Pull Up / Down Config. Field: 100K Ohm Pull Down
                                                 Hyst. Enable Field: Hysteresis Disabled */

2. cmp_interrupt.c

#define DEMO_CMP_USER_CHANNEL 3U
//#define DEMO_CMP_USER_CHANNEL 0U

Then, test:

    - CMP1_IN3 (J22-7) connected to VCC =3.3V (J24-8): USER LED on
    - CMP1_IN3 (J22-7) connected to GND (J24-7): USER LED off

The function works OK.

I find you didn't add this code:

  IOMUXC_SetPinConfig(
      IOMUXC_GPIO_AD_B1_02_GPIO1_IO18,        /* GPIO_AD_B1_01 PAD functional properties : */
      0x10B0u);                               /* Slew Rate Field: Slow Slew Rate
                                                 Drive Strength Field: R0/6
                                                 Speed Field: medium(100MHz)
                                                 Open Drain Enable Field: Open Drain Disabled
                                                 Pull / Keep Enable Field: Pull/Keeper Enabled
                                                 Pull / Keep Select Field: Keeper
                                                 Pull Up / Down Config. Field: 100K Ohm Pull Down
                                                 Hyst. Enable Field: Hysteresis Disabled */

So, please try it again.

GPIO_AD_B1_03 is the same, you can try it.

If you still have question about it, please kindly let me know.

 

Wish it helps you!

If you still have question about it, please kindly let me know.

Have a great day,
Kerry

Hi Kerry,

It is working now. A resistor connecting the voltage sense to the controller was missing. I appreciate your support. Thank you.

Hi robit ballurgi,

    Do you test it with the SDK code?

    Do you configure the pin in the pin_mux.c for your GPIO_AD_B1_02  and GPIO_AD_B1_03?

Have a great day,
Kerry

Hi Kerry,

Yes. I'm using SDK example code. And I have configured these pins.

Hi Robit,

   Please also share your pin mux code, I need to check it.

   You also can upload your problem project, then I will help you to test it on my side.


Have a great day,
