  1. 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 :)

  2. Hello! I am currently moving a project from MSP430G2553 MCU to newer MSPFR2433. I have MSP-EXP430FR2433 board and Energia-1.6.10E18 IDE Software. From the beginning I saw very strange thing - big difference in DELAY and SLEEP intervals, but only on MSP-EXP430FR2433 board. For example, even simplest elementary code for BLINK run on MSP-EXP430FR2433: #define LED RED_LED void setup() { pinMode(LED, OUTPUT); } void loop() { digitalWrite(LED, HIGH); // turn the LED on (HIGH is the voltage level) sleep(4000); // wait for 4 seconds digitalWrite(LED, LOW); // turn the LED off by making the voltage LOW delay(1000); // wait for a second } On this board interval for ON (sleep command) visually is almost equal to OFF (delay command) interval (!). So SLEEP command is running about 4 times faster, than DELAY. While same code on MSP-EXP430G2 with MSP430G2553 and MSP-EXP430FR5969 boards is working fine. What is the reason ? It looks, like Energia library for MSP430FR2433 has some issues...Is it possible to fix it ? I understand, that MSP430G2xxx and MSP430FR2xxx have differences, but some basic functions should be running the same...isn't it ?
  3. Hi, members! My name is Vladimir, I am from Chisinau city, Moldova, Republic of (a little country in eastern Europe). I am using MSP430 MCU's many years, but now working on a new project, that requires more detailed information about these MCU's. Looking forward for a nice communication here !
