What is the best practice when it comes to the physical placement of the passive anti-aliasing filter for the SD24_B ADC module inputs?
Should the passive filter components be placed right close to the chip or is it acceptable if the filter is located closer to the analogue header where the signals come into the board.

hello,
I've been trying to use two MSP430FR2433 one as a master and the other as a slave.
I used the code examples given by TI.
msp430fr243x_euscia0_spi_12 slave
msp430fr243x_euscia0_spi_09 master
The MISO waveform never goes to the zero is it supposed to be so?
Clock and MOSI waveforms are as expected
blue -> mosi
yellow -> clock
green -> miso

Hi team,
I am having a hard time finding the input impedance for the ADC on the MSP430FR5959 after a customer had asked. The only hint I can find is in the electrical specifications, ADC timing parameters on page 45:
http://www.ti.com/lit/ds/symlink/msp430fr5959.pdf
There is T-sample says that Ri = 4K. Is this the ADC series input resistance?
They were looking to confirm the max ADC input current?
Thanks in advance,
Billy

Hi,
I tested the MSP Captivate MCU – Phone Demo Board Revision E with current injection 3V RMS. We used the software generated by the Design Center version 1_60_00_00 with the enabled flag of noise immunity. The Active Mode Scan Rate is set to 40ms.
When I slide the scrollWheelSensor we see that some numericKeypadSensor are activated at the stress test frequency of 4MHz. Why is there some crosstalk under the test stage with 3V RMS common mode noise?
We are planning to use the devices for HMI Panel for household appliances and need a stable system even with current injection according to IEC 61000-4-6 conducted noise immunity 3Vrms.
What can we do to get the noise immunity of 3V RMS common mode noise?
In which steps jumps the frequency hopping? Is the frequency hopping not working?
We need some support at our location in German. Has TI an engineer in Germany who can help us with the noise immunity issues?
Thanks

Hello support,
i would like to ask for both the gross weight of the product and its dimensions, since it does not show up directly in the datasheet.
i need this info ASAP, for import issues.
The two products in the question are:

Is there an example of the code needed to interrupt the CPU on the MSP430F5529? I think that what I have should be complete, however, it does not seem to interrupt! My code looks like this:
RESET mov.w #MEMTOP8K,SP ; Initialize stackpointer
StopWDT mov.w #WDTPW+WDTHOLD,&WDTCTL ; Stop WDT
;Set P1,0 as an Output, and turn it on!

Hi,
I'm having some issue getting the MSP432 launchpad to work with the LCD on the BOOSTXL-EDUMKII, on Energia IDE.
All other examples worked except those related to the LCD where I only get a white screen.
The hardware is ok as I'm able to run the LCD related sample code supplied in the MSP432 Simplelink lib, but that's with CCS.
Was wondering if anyone has the same issue with the Energia LCD sample proejcts and any insights to what was wrong.
I'm using Energia 1.6.10E18 and the Energia MSP432 EMT RED BOARD lib, the other MSP432 BOARD LIB doesn't work with the sample projects.
Tried LCD_Joystick, LCD_LifeGame and LCD_screen_test project.
Appreciate any insights/advice.
Regards

Hi,
I have a task that occurs every 25mS in my RTOS, and this task is used to blink an LED about once per second. My watch dog is being operated through the API in the driver library. If I service the watchdog regularly, in this task, the entire system operates correctly. However, I wanted to see how the system operates if the watchdog is allowed to time out. This was accomplished by commenting out the API call that clears the watchdog timer. When the system powers up, it operates for about 18 seconds before the timeout occurs, and the LED stops blinking. Then the system never recovers. I have to cycle the power to restore operation.
Do you have any suggestions about how I can restore correct operation after the watchdog timeout ?
Thank you

Dear Sir,
I just bought the RSLK , and trying to debug the programs and understand it.
I am working on the program of 9.3 TI-RSLK Module : Demonstrating running heartbeat by adjusting the duty cycle.
The program // Lab09_SysTickmain.c runs well. But unable to get the output in the launchpad
Part Number:MSP430F5510
Hello,
My customers want to try updating of the firmware on MSP430F5510 via USB.
And, they want to try it and confirm the behavior of BSL by using EVM.
What EVM is the best to do the test of the firmware updating?
Is MSP-TS430RGC64USB suitable for the above purpose?
Best Regards,

Hello.
I have a question.
Could you tell me detail condition when VOL = 0.6V?
I think VOL max is too high.

Hi,
i'm trying to interface the ldc1000 with my msp430fr2433 launchpad.
I found the one for the msp430g2xx3 provided in the guide, how can i make them work for my launchpad?
Part Number:MSP430FR5989
Tool/software: Code Composer Studio
I have the following code:
// Setup to use internal DCO at 16 MHz
CS_setDCOFreq(CS_DCORSEL_1, CS_DCOFSEL_4);
//Set ACLK=DCO
CS_initClockSignal(CS_ACLK,CS_VLOCLK_SELECT,CS_CLOCK_DIVIDER_1);
//Set SMCLK = DCO with frequency divider of 1 for peripherals
//(16 MHz is a good rate for UART baud rate generation)
CS_initClockSignal(CS_SMCLK,CS_DCOCLK_SELECT,CS_CLOCK_DIVIDER_1);
//Set MCLK = DCO with frequency divider of 1 for main CPU
CS_initClockSignal(CS_MCLK,CS_DCOCLK_SELECT,CS_CLOCK_DIVIDER_1);When I run these lines, the system resets continuously and I see the HFXTOFFG bit is set. However if I make this change:
// Setup to use internal DCO at 16 MHz
CS_setDCOFreq(CS_DCORSEL_1, CS_DCOFSEL_4);
//Set ACLK=DCO
CS_initClockSignal(CS_ACLK,CS_VLOCLK_SELECT,CS_CLOCK_DIVIDER_1);
//Set MCLK = DCO with frequency divider of 1 for main CPU
CS_initClockSignal(CS_MCLK,CS_DCOCLK_SELECT,CS_CLOCK_DIVIDER_1);
//Set SMCLK = DCO with frequency divider of 1 for peripherals
//(16 MHz is a good rate for UART baud rate generation)
CS_initClockSignal(CS_SMCLK,CS_DCOCLK_SELECT,CS_CLOCK_DIVIDER_1);
Everything works fine! Also if I configure all clocks at the same time that is fine as well. Also if I drop to 8 MHz that's fine as well. It's only the combination of 16 MHz and initalizing SMCLK *before* MCLK that causes the processor to continuously reset.

Hi,
I just found that the bigtime example is implemented for a few LaunchPads and I did some tests.
MSP-EXP430F5529LP - skipped, no MPU
MSP-EXP430FR5969 - fails in the same way like on 5994.
See bug (TIRTOS-1077).
MSP-EXP430FR6989 - MPU enabled, "Let compiler handle ..." option selected and ...
it WORKS!
Looks to me that the bigtime example error may be related to a linker default allocation and some linker file modifications rather than TI-RTOS bug.
I have very, very basic knowledge regarding linker files and without additional learning I have investigate that problem on a linker level, if any problem.
Hope this help you investigate the (TIRTOS-1077) bug.
Best regards,
Tomasz
