    MSP430FR2433 SleepSeconds 18ua

    Yes this is the conclusion I have come too. I believe Energia' implementation of the Watchdog here is what causes the higher usage. It is very impressive that it manages to get even close. I think it is abit misleading to call SleepSeconds() true LPM3 though. It would be great to see some other implementation though; as the MSP430 is capable of sub 1ua sleep. Perhaps I will experiment with a library in the future to make this possible. Thanks for your response.

    Energia and Wolverine - Tips

    Is this still the recommended way to use FRAM with Energia?

    Using FRAM above 0x00010000

    That LoRaWAN Gateway is awesome. Would love to see the source for all this.
  4. Hey Kreitzz, 

    I saw  you were using the sleep functions on the MSp430FR2433.

    Wondering what kind of power usage you have been experiencing? And if it is lower than 18ua; what have you done to get it lower? 


    Thanks :)

    MSP430FR2433 SleepSeconds 18ua

    I think messing with the power regulator is no good. My 'implementation' of it with Energia breaks SleepSeconds and the device restarts. Any assistance with getting current using SleepSeconds below 17ua would be greatly appreciated.

    MSP430FR2433 SleepSeconds 18ua

    Using Driverlib without energia I am able to get VERY low consumption (less than .5ua) Would love to know how this can be integrated with Energia SleepSeconds. Thanks. WDT_A_hold(WDT_A_BASE); P2SEL0 |= BIT0 + BIT1; // P2.0: XOUT; P2.1: XI1 //CSCTL4 = SELMS__DCOCLKDIV | SELA__XT1CLK; // MCLK=SMCLK=DCO; ACLK=XT1 // Port Configuration all un-used pins to output low P1OUT = 0x00; P2OUT = 0x00; P3OUT = 0x00; P1DIR = 0xff; P2DIR = 0xff; P3DIR = 0xff; PM5CTL0 &= ~LOCKLPM5; // Disable the GPIO power-on default high-impedance mode // to activate previously configured port settings PMM_turnOffRegulator(); __bis_SR_register(LPM3_bits + GIE); // Enter LPM3 __no_operation(); // For debug
  7. Hi, I'm working on a board with an FR2433, and also doing testing with the FR2433 Launchpad. I am trying to troubleshoot high current using SleepSeconds() With Suspend, I can get 1.5ua but sleep seconds is around 18ua, I believe it should be far lower based on the datasheet for LPM3. I am using a ucurrent gold so feel confident about the measurement. I set all my pins (1-22) to OUTPUT LOW and have also tried with INPUT_PULLDOWN Any assistance here would be greatly appreciated. Thankyou.
  8. . Hey Kreitzz, I would be interested to know if you have tried using sleepseconds with any different results. I am using the same board and am hoping to get low power sleep working as well.
