I face the same problem while programming MSP430FE4272 MCU,I programmed successfully by the MSP-FET and ofcoarse by the Guang Programmer too if I set the VCC supply to " supplied by programmer" "whole range". But when I configure the device to be supplied from "External" it shows me an error 13 VCC is too low. I measured and found that the external VCC is 3.2 volt. Any solution please?
here is the snap shot of the error
Part Number:MSP-FET
Tool/software: Linux
My issue is related to This Post. It seems that newer MSP-fet devices do not work under Linux. We ordered a new MSP-fet device (Serial number begins with 17 and ends with W).
In Linux (Lubuntu 15.10), using MSP430-Flasher v1.3.8 we get the error "Could not set device VCC" (same symptom as described in the referenced post).
Updated MSP430-Flasher to v1.3.15 and ran the msp430uif_install.sh script from the Driver folder but still receive the same error (Could not set device VCC).
Note that the Old MSP-Fet still works in Linux with MSP430-Flasher v1.3.15.
Interestingly, I found the following under Windows
New MSP-Fet: Using MSP430-Flasher v1.3.8: receive "Could not set device VCC" error (as expected)
New MSP-Fet: Using MSP430-Flasher v1.3.15 works properly (as expected)
Old MSP-Fet: Using MSP430-Flasher v1.3.8 works properly (as expected)
Old MSP-Fet: using MSP430-Flasher v1.3.15 Prompts for firmware upgrade (did not do this in Linux). I said no for fear that doing so would prevent it from working under Linux, then received "Could not set device VCC" error.
I would like to be able to use either device under either OS, but at the very least, the new MSP-fet should work with the new MSP430-Flasher under Linux.
Thanks.

hello Sir,
please help me to slove the problem, i my pcb i am using msp430fr5729 controller in that i have used 8 mhz clock and for that i had made changes in CSCTL register as shown below, my problem is that in my some pcb my code get stuck in "do..while" loop which is given below but in some pcb it does not stuck there and was working fine. The ratio for working out of not working is 7/10 works and 3/10 fail. i just want to what is the problem?, the same code loaded in all 10 pcb out of which in 3 it was stuck in do while loop, does there will be problem in crystal or in controller, please help me to slove this.

Hello! I'm using the Fuel Tank MKII Battery BoosterPack Plug-In Module with a MSP-EXP432P401R Rev. 2.1 Launchpad and the example from MSP432 Simplelink SDK 1.40.1.00 (boostxl_batpakmkii_fuelgauge_MSP_EXP432P401R_nortos_ccs).
I've noticed that when first running the example it does not read the State of Charge and Remaining Capacity (it says 0% and 0 mAh). All other parameters are read fine. These are the steps to reproduce the issue:
1. Connect battery to plug-in module;
2. Connect the plug-in module to the Launchpad;
3. Disconnect 3V3 and 5V jumpers from the Launchpad;
4. Connect the USB cable to the Launchpad;
5. Switch the battery pack on.
6. Program and run the example.
When this happens, if I stop the program and restart, then it reads OK.
Can anybody reproduce the issue? Is there a problem with my hardware or is it a software-related problem?

I have a MSP432P401R LaunchPad (version 1) and download the SimpleLink™ MSP432P401R LaunchPad™ Development Kit. However, when I tried to run the example program adcsinglechannel_MSP_EXP432P401R_tirtos_ccs in CCS v7, it does not work. When I tried to debug it, I found that after run the "BIOS_start();" in the "main_tirtos.c", "adcsinglechannel.c" did not start and the program had no more response further. Could anyone tell me why and how to solve the problem? Thanks a lot!

I have a device that uses voltage output from a piezoelectric element to wake it up. In a prototype I built I amplified the signal using a OP-amp to generete the output needed to wake the device up. Is it possible to use the internal OPamp in this MCU for this purpose? That is, is the OP amp powered when the MSP430-device is asleep?

Hello,
I have some problems to configure the eUSCI with the correct settings and the right clock settings/deviders. First I think the hardware is okay. There are some bus participans wokring on Atmel processors and some bought ones. Between the RS485 IC and the MSP430 the scope shows me valid Data (analog scope, not data logger). For this reason I think I only fail with the right software settings. ;-)
I'm using IAR Embedded Workbench IDE 6.50.5.
I tried to remix some code examples: https://github.com/j-windsor/MSP430-DMX512/blob/master/main.c

}I am a little bit confused with all the settings of the eUSCI. On page 575 of the Family/Users Guide there are some correction/modulation patterns. I just thought I can set the Clock to 8MHz and devide it down to 250 kBaud. The datasheet makes differences on page 576, if you will need a devider of more or less than 16. The example in slac700 is only for 9600 Baud and need all the corrections, right?
I would be very pleased if anyone has additional information or hints for me! :) I hope I pasted all important information.

Part Number:MSP430G2855
Tool/software: Code Composer Studio
Hello,
I've bought a MSP430G2855 microcontroller and I will program it with the launch pad (MSP-EXP430G2) and Code Composer Studio (V 7.2.0). But when I compile and run the program, Code Composer shows the error message:
"Error connecting to the target: Could not find device (or device not supported)"
Under "project --> properties" the correct controller is selected. I have connected the pins DVCC, DVSS, AVCC, AVSS, TEST and RESET between the mc and the launch pad and the slot of the launch pad ist empty.
Is it even possible to program this microcontroller with the launch pad "MSP-EXP430G2"? On the ti-webseite of the microcontroller, this launch pad is listed under "tools & software", but in the manual of the launch pad the controller MSP430G2855 isn't listed under "supported devices". The othere comtrollers (for example "MSP430G2553") works fine with this configuration.
Where is my mistake?
Cheers
Marcel
Part Number:MSP430F5529
I would like two EXP430F5529LP launchpads to communicate with each other. I am trying to use the CDC (Virtual COM port) examples from the USB Developer's package. I have loaded the C0_Simple send in one Launch pad and C1_LEDOnOff example in the two launchpads. I tried Debugging the launchpad which contains C1_LEDONOff example. It seems like the data is not recieved. (I know as the program is not going into " if (bCDCDataReceived_event)" condition). I have connected P3.4 to P'3.3 and P3.3 to P'3.4 (Tx to Rx and Rx to Tx UART GPIOs).
My question is whether two MSP430 could communicate using CDC_APIs? If yes, what am I doing wrong? How is C1_LEDOnOff example recieving data? I see USBCDC_receiveDataInBuffer subroutine being used to recieve data but it is mentioned that the
/* This call only retrieves data that is already waiting in the USB buffer -- that is, data that has already been received by the MCU.
I dont see the function USBCDC_receiveData() being used.
Thank you in advance.

Part Number:MSP-EXP430FR5994
Tool/software:TI-RTOS
I have been using the simple TI-RTOS example project under Code Composer Studio version 7.2 to do some low-power mode testing. I disconnected the jumper for LED0 and setup the TI-RTOS configuration for dynamic idling and to idle in LPM3. EnergyTrace told me the board was drawing 174 uW of power in LPM3 (52.7 uA at 3.3V). I knew there was another demo that did not use TI-RTOS that had much lower power consumption in LPM3. I copied the clock settings from that demo, which is shown below:
PJSEL0 = BIT4 | BIT5; // For XT1
// Clock System Setup
CSCTL0_H = CSKEY_H; // Unlock CS registers
CSCTL1 = DCOFSEL_0; // Set DCO to 1MHz
CSCTL2 = SELA__LFXTCLK | SELS__DCOCLK | SELM__DCOCLK;
CSCTL3 = DIVA__1 | DIVS__1 | DIVM__1; // Set all dividers
CSCTL4 &= ~LFXTOFF;
// Configure LED pin for output
P1DIR |= BIT0;
// Disable the GPIO power-on default high-impedance mode to activate
// previously configured port settings. The oscillator should now start...
PM5CTL0 &= ~LOCKLPM5;
do {
CSCTL5 &= ~LFXTOFFG; // Clear XT1 fault flag
SFRIFG1 &= ~OFIFG;
} while (SFRIFG1 & OFIFG); // Test oscillator fault flag
After making this change, the power consumption dropped to 8.9 uW in LPM3 (2.7uA at 3.3V). I believe TA0 is running at a very high clock rate by default and is consuming a lot of power in the low power modes. Is there a TI-BIOS configuration option to slow down the TA0 clock? I tried setting Clock.tickPeriod to 100000 but that did not seem to have an effect on power consumption.

I am debugging my code, and need to what happens when my MPU resets after tripping the WDT. However, every time the WDT trips, the code enters the resetISR function, and hits an invisible breakpoint. How do I get my code to hit the resetISR and just reset without stopping?
