I generated 4 PWM (two pairs of complementary with deadtime) simultaneously in MSP430G2553 using interrupt as we have only two timers in this part.
The PWM is flickering when the duty is varied according to the value through ADC. Please help me to resolve the issue.

Part Number:MSP430G2553
Hi All,
I have some code which has high sleep current during LPM4. I have made a branch that ripped everything out except a) setting all pin assignments, b) setting some clock, ADC, UART settings, c) going to LPM4 sleep So basically, system turns on, does some housekeeping and goes to sleep.
The high sleep current in LPM4 -may- be hardware-related but I need to ensure that the software is bulletproof before suggesting that.
Here is a code snippet. All the pin assignments (P1DIR, P1REN,P1OUT, etc.) are set to an output high or low, no resistor enable. All the port select settings (PSEL, P2SEL, P3SEL, etc.) are set to 0, so the port are all general purpose I/O.
///////////////////////////////////// code snippet ////////////////////////////////////
DCOCTL = 0; // Select lowest DCOx and MODx settings
BCSCTL1 = CALBC1_1MHZ; // Set DCO
DCOCTL = CALDCO_1MHZ;
// disable UART
UCA0CTL1 |= UCSWRST; // **DEACTIVATE USCI state machine**
IE2 = 0; // disable all USCI_A0 interrupts
// disable ADC conversion
ADC10CTL0 &= ~ADC10IE;
ADC10CTL0 &= ~ADC10ON;
ADC10CTL0 &= ~REFON;
ADC10CTL0 &= ~ADC10SHT_2;
ADC10CTL0 &= ~SREF_1;
// stop watchdog timer
WDTCTL = WDTPW + WDTHOLD; // Stop WDT - also resets clock to SMCLK
__bis_SR_register(LPM4_bits); // Enter LPM4 - NO global interrupts enabled
///////////////////////////////////// end of code snippet ////////////////////////////////////
Is there anything wrong with doing the above? Anything else I should do before going to LPM4?
My understanding is that LPM4 basically disables everything - clocks, etc. so really those settings shouldn't matter. Does anyone have any code references for entering LPM4?
Thank you!

Hello everyone,
I am currently using an MSP430FR2355 and am trying to take in an ECG signal using ADC Channel 1. The minimum voltage of the signal is roughly 200mV and the maximum voltage is 2.4V. I would like to take the adc values in continuously off this channel so that I can output them to an OLED display. However, when I run the code provided below, every value in the array is equal to 1. I am sure I am doing something wrong, however I am unable to figure it out. Any help would be greatly appreciated. Thanks in advance!

Hi,
When I was trying the hibernation mode suddenly I am not bale to program the board after doing certain IO changes.
Its giving me error of
Error connecting to the target:
(Error -2062 @ 0x0)
Unable to halt device. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK).
(Emulation package 8.0.903.2)
So could some one please help me out to bring it back ..
Thank you!!

Hi,
I have implemented analog to digital voltage conversion using the internal reference voltage of msp430f2003 AD16.However, when I use the external reference voltage, it cannot be used.
Internal reference software configuration: SD16CTL = SD16REFON+SD16SSEL_1;
External reference software configuration: SD16CTL = SD16SSEL_1;
Internal reference hardware: the VREF is grounded by a 104 capacitor.
External reference hardware: VREF with 3.0V LDO (LP2985IM5X) divided by two 100K resistors.
Can you help me identify the problem.
Thanks
best Regard.

Part Number:MSP-CAPT-FR2633
MSP Captivate Devices used for testing:
1) Captivate Programmer Rev C
2) Captivate FR2633 Rev C
3) Captivate BSWP Rev B
4) Micro usb cable arrived in Box.
System Environment:
1) Operating System: Ubuntu 16.04 LTS (64 bit, x86_64)
2) Design Center: 1.80.00.30-linux-x64
3) CCS: CCS9.0.00018_linux-64
4) JDK: 1.8.0_201
Did CCS & Design Center setup as normal user.
Installed Drivers as Root User.
Added below line to hid.rules : /etc/udev/rules.d/ti_hid.rules : ATTRS{idVendor}==”2047”, MODE=”0666”
Used Design Center to design and created code. Installed the Code to device using CCS. Red light blinked while loading.
Proximity sensor works properly on BSWP. Proximity light glows and goes after 2 seconds when hand is removed from board.
=============================================
Issue Faced:
1) Design Center is unable to connect to board as Normal User (some exception is thrown).
2) Design Center connects to board when run as Root User. But, doesn’t receives the data (some exception is thrown).
Note: As a Normal or Root User, in both the cases, CCS automatically detects and connects the board. Also, run time debugging works.

Devices when connected :
1) When the Programmer board is connected to machine, devices gets added at run time under this location
/dev/ttyACM*
a. ttyACM0
b. ttyACM1
2) The default permissions of ttyACM0 & ttyACM1 were User as Root and Group as dialout.
Just gave a random try with various below options to make the design center work in normal user mode, but was unable to succeed.
3) I have added self-user sujit to dialout group. (did not worked)
4) Changed ttyACM0 & ttyACM1 Group to sujit. (did not worked)
5) Changed ttyACM0 & ttyACM1 User to sujit. (did not worked)
6) Changed mode of both the devices to Read-Write-Execute (777). (did not worked)
7) Note : The ttyACM0 & ttyACM1 devices permissions gets RESET to default permissions as the USB cable is removed from machine and plugged again.
Appreciate your inputs for the same.

Hi,
I have question about of UCS Module Fail-Safe Operation.
We are facing the issue of increased power consumption due to UCS fail-safe operation.
We are using XT1 operation ins LF mode, when a clock failure occurs in XT1, the fail-safe function switches the clock source, and as a result only MSP430 has a current increase of about 4μA.
Although the oscillator failure has been removed and the DCOFFG, XT1LFOFFG, and OFIFG registers have been checked to confirm that the failure has been removed, a current increase of about 1μA can be seen compared to before the occurrence of the oscillator failure.
We predicted that the current consumption would be equal since the clock resources would return to their pre-fault state when the MSP430 recovers from the oscillator failure. Wwhat is the reason for the 1A current increase?
Best Regards,
H.U

Hello,
I am working on ADS1293EVM which also contents MSP430F5529. My goal is real time acquisition of the ecg data. To understand, I am absolutely beginner in programming.
I was trying to launch demo3 from "MSP430 Interface to ADS1293 Code Library". It always stuck on this while and I do not understand why.
I will appreciate any help with this trouble. Do you know any other codes for interfacing these devices. I will be glad for any inspiration how to solve the communication.
I am not able to display any data as well. I will also appreciate any advice how to display these data.
Thank you,

Hello,
I am creating a circuit designed to be partially powered down for long periods of time. When it is fully powered, my microcontroller will act as an I2C slave and respond to commands on the bus. However, when the circuit is partially powered down, the microcontroller will continue to be powered off of a battery, but the I2C bus and master will not be powered. In this case, what is the best way to configure the I2C port to minimize power loss? Is it safe to set the pins as GPIO outputs and set them low? Will that cause any problems when the circuit powers back up and needs to use the I2C bus again? Or is it better to set them as inputs and pull them up off of the battery rail? If so, what's the highest resistance I could use? I have provided an image to better explain this.
When fully powered on, VCC = VBAT = 3.3V. When partially powered down, VCC = 0V and VBAT = 3.1-2.5V.

Our application uses SSI1 with (MSP432E SLSDKv2.40.00.11) SDSPI driver to access an SD card. We found that the driver doesn't work when we specify uDMA channels 10 and 11, but it works fine with uDMA channels 24 and 25. I confirmed that all uDMA channels are set to default priority.
The TRM and TI driver header files suggest that both channel pairs are supported for SSI1. Is this a known H/W limitation or could we be missing a step in the driver initialization?
This configuration works correctly:
const SPIMSP432E4DMA_HWAttrs spiMSP432E4DMAHWAttrs[MSP_EXP432E401Y_SPICOUNT] = {
{
.baseAddr = SSI1_BASE,
.intNum = INT_SSI1,
.intPriority = (~0),
.defaultTxBufValue = (~0),
.rxDmaChannel = UDMA_CH24_SSI1RX,
.txDmaChannel = UDMA_CH25_SSI1TX,
.minDmaTransferSize = 10,
.clkPinMask = SPIMSP432E4_PB5_SSI1CLK,
.fssPinMask = SPIMSP432E4_PB4_SSI1FSS,
.xdat0PinMask = SPIMSP432E4_PE4_SSI1XDAT0,
.xdat1PinMask = SPIMSP432E4_PE5_SSI1XDAT1
}};
This configuration does not work:

{
.baseAddr = SSI1_BASE,
