Part Number:MSP432E401Y
Hi,
I have a MSP432E401Y Launchpad, with XDS110 debug interface. I reflashed the bootloader for XDS by mistake, and now I am not able to proceed with any board debug.
I had used the following command to reflash XDS bootloader -
xdsdfu -m
xdsdfu -b bootloader.bin -r
I gave a wrong bootloader file and now it doesn't boot.
Is there a way to reflash the complete firmware ?

Hello,
I am trying to put the MCU to hibernation mode using the example code "hibernate_vdd3on_wakepin" and measured the current using power supply of 3.3v , its measuring 20mA ,whn MCU is in sleep/hibernate mode.
Can I know how to pulldown the current consumption completely that draws only very few micro amps during sleepmode..
Even whn I tried with "sysctl_deepsleepmode_gpiowake" ,its drawing same 20mA current.
Can I please know how to reduce it and whr I am doing wrong..
According to the DataSheet it should be 1.04 - 2.14uA..
Thank you!!

Hi,
we are using three phase capacitive power supply with MSP430F47187.my issue is that when we do calibration in UPF side ie 1.00 upf then meter is calibrated in upf but when are giving 0.5 lag to meter then accuracy is showing 100% .i am following the capacitive supply as given in ti pdf .voltage sensing and current sensing is also same as given reference by ti but problem occuring in 0.5 lag. please revert what is the issue in hardware.
Part Number:MSP430F2272
I'm in the process of creating a small archival tag using the MSP430f2272 microcontroller and there is a restraint on the size of the PCB.
I am looking for some type of JTAG headers that are much smaller of the legacy ones. Does someone have any tips on getting started there? Some reference designs would help greatly
I'm attaching an image of what I am kinda looking for. I am currently using the MSP-FET debugger
Thanks.

Hi,
I am working on msp430G2553 . I am producing PWM signal on P2.5 , it works properly when debugger is connected . But when debugger is removed , the pwm signal is missing . Why is it so ?
Part Number:MSP430FR2311
I'm using an MSP430 as an I2C slave. It seems that it would be easier to clear a stuck bus on the slave end rather than doing the bus clear from the master end and going through all the pin reading, reconfigure the i2c pins to gpio, clocking out until the bus clears, etc. On the slave side it seems you could just monitor the state machine and make sure whenever there is an i2c start interrupt you start counting using a timer. You also give the transaction a unique ID and then use a counter that checks that unique id. If the counter gets to some specified timeout (lets say 1 second) and the unique ID hasn't change then, reset the peripheral and state machine which should clear the stuck bus.
Thoughts?

Hi TI team,
Please if you can suggest any Fuel Gauge composant or development kit with a source code or something similar to communicate with MSP430F5529.
I need it to read the state of charge of the battery.
I found many exemples like (BQxx ....) but with all of it I can't have any result .

Hello,
I have an UltrasonicWaterFR6047_01_40_00_01 application and I want to update the USSLib of the latest version. What is the procedure I should follow to update the USSLib in my Demo application.

Part Number:TIDM-1019
I am working on using the latest USS design center GUI and I have been successful in getting the code to compile after running thru the calibration process and creating the new header files.
Additionally, per your calibration flow diagram (provided in a different thread), I have commented out the gUssSWConfig.algorithmsConfig->numOfMeterCalibrationRanges to zero, in the USSLibGUIApp_Init() function inside of USSLibGUIApp.c file. This was also part of the compile I performed before programming the eval board.
So, the result of all of this is that the meter appears to run without the 'Adv. Calibration Table' checkbox checked (although the flow rates are not accurrate at some of the sample points because our meter has some non-linear behavior). When I check the box for 'Adv Calibration Table' the VFR drops to the offset values for the flow range that the meter is running in...
In my application, my meter runs from 0 to 33 GPM. I have three linear ranges:
The first range is: 0 to 2.5 GPM where the slope is around 0.92 and the offset is -0.04
The second range is: 2.5 to 10 GPM where the slope is around 0.96 and the offset is -0.3
The third range is 10 to 33 GPM where the slope is around 1.02 and the offset is -0.5
The GUI shows -0.5 when I run the flow thru the meter at 20 GPM.
The GUI shows -0.3 when I run the flow thru the meter at 5.0 GPM.
The GUI shows - 0.04 when I run the flow thru the meter at 1.0 GPM
In my testing it appears that following your process the meter only outputs the offset and not the VFR when the 'Adv Calibration Table' checkbox is checked.
Please provide your thoughts ASAP. I have tried to mine thru the source code and determine what is going on, but the only thing I can see is that the values are being returned that way from the USS SW lib function calls.
Any advice would be great.

Edwin

Hi,
I am trying to build a custom boot loader for MSP430f6779a device, based on MSPBSL_CustomBSL430 1_01_00_00 source in CCS ( Version: 7.4.0.00015 ). In the BSL430_Low_Level_Init.asm , I have made necessary modifications in BSL Protect function to switch the controller to BSL mode based on pin P2.2 (kindly confirm wether i can write like that). Unfortunately the BSL is not working as expected., also noted the section .JTAGLOCK_KEY is not placed in the output file.
For your reference iam attaching zip containing BSL430_Low_Level_Init.asm,BSL_lnk_msp430f6779a.cmd ,output.map and output .txt file. Please help.

Hi Everyone,
I am using MSP430F6779A for my project in which i am facing issue with RTC time. When power is cutoff my RTC freezes the last time and continues to run when power is restored. I need my RTC to continue running even during powerfail. I have connected battery on VBAT and i can see the crystal oscillating on my scope which ensures no fault in my hardware. I found one thread running on this forum relevant to my question e2e.ti.com/.../583815 . I have tried the answer mentioned in the same thread but my problem remains same. I tried with RTCLOCK and RTC_C also but of no use. I believe i have tried most of the online help online in this regards but could not solve my problem. I used MSP430Ware code to initialise my RTC for first but later on did many helpless experiments with that. Now i am here, anyone knowing the issue please help me asap.
One more thing here i want to mention that i am using MSP430F6736 for one more of my project in which my RTC runs as expected no issue with that. I tried same code of RTC but doesnt work out on 6779A.
Thank you so much in advance for anyone helping me out of this situation. This is the last hurdle my project is stuck for release

Hi,
I am using PORT Interrupts.
My Program is :
i) P2.7 is connected with switch (Interrupt).
ii) P3.2 is connected with LED.
When switch is pressed, LED will be on.
/*

pattern=1;
__bic_SR_register_on_exit(LPM3_bits);
}
}

P3OUT &= ~BIT2; //LED is working, I tested it without interrupt in my customized board.
__delay_cycles(800000);
P3OUT |= BIT2;
}
}
//return 0;
}
Can anyone please tell me,
what mistake I am doing?
so that the Interrupt is not working.

Part Number:MSP432P4111
Tool/software: Code Composer Studio
I'm trying to program a relatively basic thing, a stopwatch. I have a MSP432P4111 launchpad which has a built in LCD.
1. My project needs to be triggered by an switch, to start and stop the clock
2. Show the time on an LCD
3. Display the same time via UART, and hopefully Bluetooth later
4. Be accurate to the millisecond.
I've reviewed example projects like:
lcd_f_animated_text_MSP_EXP432P4111_nortos_ccs uartecho_MSP_EXP432P4111_nortos_ccs gpio_input_interrupt_MSP_EXP432P4111_nortos_ccs msp432p411x_rtc_04_MSP_EXP432P4111_nortos_ccs
It seems like all of the example projects have different included files or build options, like if i try to add " #include <ti/devices/msp432p4xx/driverlib/driverlib.h> " to a project that didn't have it already I always get ""C:/ti/simplelink_msp432p4_sdk_2_40_00_10/source/ti/devices/msp432p4xx/inc/msp.h", line 76: fatal error #35: #error directive: "Failed to match a default include file" "
It's extremely frustrating, if I programmed this with Arduino I would be done in a day, but I have to use code composer studio for "school reasons". I know Arduino isn't as fast or accurate but it's really nice how the same code works on different boards.
Can someone please tell me how to make a project with all the necessary includes and options for my project?
This is the code i have so far, it's based off the animate text example. I tried to mix and match different examples but it's not working right.
please help!

In 
it is mentioned that there are Eagle schematics for various launchpad designs. The document MSP432P401R SimpleLink™ Microcontroller LaunchPad™ DevelopmentKit (MSP ‑‑ EXP432P401R) slau597f.pdf (
) contains a schematic, but no links to eagle library or schematic file sources. Can users download these from TI ?

Hi,
I just upgraded the MSP432E401Y SimpleLink SDK from version 2.30.00.14 to version 2.40.00.11. My application has a thread that periodically makes HTTPClient requests via my wired ethernet connection. Prior to the upgrade I had no problems sending requests or receiving responses from my web service and the thread runs stable. Since the upgrade and running the exact same baseline of my software, the thread runs for a few seconds then the HTTPClient_connect() fails with a -10 error code. If I switch back to version 2.30.00.14 and rebuild, all works fine. I checked the release notes for version 2.40.00.11 and did not see anything that would impact the HTTPClient interface. I am using Code Composer Studio v8.2.0.00007. Any ideas on why this is happening?
Thanks,

Hello everyone,
I am trying to use Ti-RTOS on MSP430FR6989. I have copied GPIO Interrupt Driver Example project provided by TI to my current workspace (I have tried simple Kernel Examples too). Even though project builds without errors and warnings, it is not running as expected. It prints the message "MSP430: AutoRun: Target not run as the symbol "main" is not defined". To see whether the issue was because of copying old CCS project (I believe TI example uses older version of CCS) to new workspace, I have created new project and copy the source files. Again, project builds fine but gives the same problem as before.
As you can see disassembly in the screenshot below, there is some problem. However, I can not figure out the actual reason. Please help me to fix this.
Thank you,
Mounika

Hi,
I'm using MSP430F5528 for one of my project, I'm flashing my code into MSP430F5528 using MSP-FET. I'm able to run the code when I go step by step execution, but if I run the code at once I'm unable to get my output, it will go for no operation mode.
And also once after flashing, if I restart my MSP430F5528, it's not automatically running my code, I'm able to run other example codes on restart .
Do I need to do anything to work it on Reset? Please let me know.
Thanks in advance.

Strange problem here, but the spi module is transmitting only 34 (base 10) or 0 (base 10) no matter what I send to the UCA1TXBUF. Below is a scope grab of the spi problem transmitting 34,
Here is a scope screen shot of the spi transmitting 0,

Part Number:MSP430FR5969
Tool/software: TI C/C++ Compiler
In recent tests I have found a problem: the power consumption of about MSP430FR5969 in SPI communication will eUSCIA configuration for SPI mode (UCCKPH configuration is 1, UCCKPL configuration is 0, the host mode, start high), once every 4 ms for SPI communication, the power consumption about 15 ua (when no communication has been in LPM3 mode).In the process, when the lowest MISO bit is 1, and the end of the communication MISO pins jumping from 1 to 0, the current will happen suddenly become larger, MSP430FR5969 power consumption up to 170 ua (also in LPM3 low power consumption)and sunstain.
AT the same time monitoring module UCBUSY always jump between 0/1, while SPIB under same configuration module will not appear these problems.MSP430FR5969 errata in your company manual, reference to similar problems to SPIA module (issue number: USCI41), doubt has strong correlation with the problem.
To help clear the problem, I wrote a simple test code in Development board (MSP430FR5969 LaunchPad ™ Development Kit) on the minimum system, can describe the bug before the repetition.The basic idea is to use MSP430FR5969 IO port output to simulate from the sending end of machine, connected to the MSP430 P2.1 SPI input port (UCA0SOMI).When the SPI to receive 8 bits of data are all 1, after the SPI communication, pull UCA0SOMI port by IO output low, at this point MSP430FR5969 current will increase to 170 ua, at the same time monitoring module UCBUSY always jump between 0/1.
