CC2530: Turn off or Force LPDS

Jack Loop

Part Number: CC2530
Other Parts Discussed in Thread: Z-STACK

Hi,

I wanted to know if it was possible to program the CC2530 to turn off or force it into deep sleep forever. This is my failsafe to ensure that the CC2530 doesn't do anything weird if the voltage is too low since I have forced to do nothing. How could I do this?

You can try to make CC2530 enter PM3 using the following code:

SLEEPCMD |= 0x03;
PCON = 0x01;

Thanks. Is it also possible to ignore interrupts?

0 YiKai Chen over 7 years ago in reply to Jack Loop

Guru 735685 points

Yes, you can disable all interrupt.

0 Jack Loop over 7 years ago in reply to YiKai Chen

Guru 17870 points

What's the code for that?

0 YiKai Chen over 7 years ago in reply to Jack Loop

Guru 735685 points

You can set PxIEN registers to disable all interrupts.

Guru 17870 points

Thanks. And is there an existing function that can already shut pretty much everything down (i.e. RX, TX, I/O, clocks, etc.)?

0 YiKai Chen over 7 years ago in reply to Jack Loop

Guru 735685 points

Entering PM3 would shut everything down.

Guru 17870 points

What's the code to exit out of PM3 and return to normal operation?

0 YiKai Chen over 7 years ago in reply to Jack Loop

Guru 735685 points

Use any pin as GPI interrupt to wake up CPU from PM3.

0 Jack Loop over 7 years ago in reply to YiKai Chen

Guru 17870 points

What is the code from the interrupt that brings the CC2530 back to normal operation?

0 YiKai Chen over 7 years ago in reply to Jack Loop

Guru 735685 points

It’s like register interrupt in hal_key.c

Jack,

Please refer to this E2E thread for an example of someone waking up the CC2530 from sleep using interrupts e2e.ti.com/.../62053

Is it possible to still blink an LED even though I put the CC2530 in PM3? Could I still use HalLedBlink?

0 YiKai Chen over 7 years ago in reply to Jack Loop

Guru 735685 points

No, you can’t.

0 Jack Loop over 7 years ago in reply to YiKai Chen

Guru 17870 points

Can I force the CC2530 to enter PM2 by doing the below, and be able to blink an LED?

SLEEPCMD |= 0x02;
PCON = 0x01;

0 YiKai Chen over 7 years ago in reply to Jack Loop

Guru 735685 points

If your device is in PM3, you still have to wake up it with GPI interrupt and then you can set it to PM2 to do led blinking.

0 Jack Loop over 7 years ago in reply to YiKai Chen

Guru 17870 points

I will force to PM2 instead of PM3. Does above code achieve PM2?

0 YiKai Chen over 7 years ago in reply to Jack Loop

Guru 735685 points

Original Z-Stack will enter PM2 automatically and you don’t have to do anything other than define POWER_SAVING.

....Going back to the PM3 code, I tried doing this:

  if ( !OSAL_NV_CHECK_BUS_VOLTAGE )
  {
    P1_4 = 0;
    P1_5 = 0;
    
    P1_2 = 0;
    P1_3 = 0;
    
    HAL_DISABLE_INTERRUPTS();
    
    SLEEPCMD |= 0x03;
    PCON = 0x01;
    
    return NV_OPER_FAILED;
  }

But I see a power consumption of 6mA. What might be causing this?

0 YiKai Chen over 7 years ago in reply to Jack Loop

Guru 735685 points

Have you been successfully made your CC2530 enter PM3 and see current consumption less than 1uA?

0 Jack Loop over 7 years ago in reply to YiKai Chen

Guru 17870 points

No. I said I see 6mA power consumption - only happens when CC2530 was in the middle of a task (e.g. on/off).

0 YiKai Chen over 7 years ago in reply to Jack Loop

Guru 735685 points

It is normal to see 6mA power consumption - only happens when CC2530 was in the middle of a task (e.g. on/off) since CC2530 is in active mode.

Guru 17870 points

I want to force to PM3 though. Wasn't the code posted earlier supposed to do that?

0 YiKai Chen over 7 years ago in reply to Jack Loop

Guru 735685 points

When will those codes be called?

0 Jack Loop over 7 years ago in reply to YiKai Chen

Guru 17870 points

Only for instances of "if ( !OSAL_NV_CHECK_BUS_VOLTAGE )" inside of OSAL_NV.c

0 YiKai Chen over 7 years ago in reply to Jack Loop

Guru 735685 points

If you set a breakpoint inside “if ( !OSAL_NV_CHECK_BUS_VOLTAGE )...”, does it hit?

0 Jack Loop over 7 years ago in reply to YiKai Chen

Guru 17870 points

Yes.

0 YiKai Chen over 7 years ago in reply to Jack Loop

Guru 735685 points

I means your CC2530 should enter PM3. When you test it, do you disconnect CC Debugger from your CC2530?

0 Jack Loop over 7 years ago in reply to YiKai Chen

Guru 17870 points

Yes.

0 YiKai Chen over 7 years ago in reply to Jack Loop

Guru 735685 points

To make sure it really enter PM3, can you call HalLEDBlink to make LED keep blink before you make device enter PM3 to do the test again. If the LED keeps blinking, it means device doesn’t enter PM3.
