Part Number:MSP430FR6989

Tool/software: TI C/C++ Compiler

Hello,

I want to purchase MSP430FR6989 Launchpad and I want to make a code in Energia.

There are LCD_Launchpad.h is there.Yes,I able to run demo code in Custome LCD in Launchpad.

But If I will drive our own customize LCD on MSP430FR6972 MCU.Then as per my segments which portion of code I need to modify in LCD_Launchpad.cpp and LCD_Launchpad.h.

Here I am attach"LCD_Launchpad.h" and "LCD_Launchpad.cpp" files.

Please give me an idea for our custom LCD programming.

Regards,

BOOSTXL-AUDIO: help in coding

Part Number:BOOSTXL-AUDIO

Hello, I'm using MSP- EXP430FR5994 and BOOSTXL-AUDIO. I want to generate a voice output everytime a switch is pressed. The output of the audio has three sources: (1)DAC on the BOOSXL-Audio;(2)DAC on the Launchpad(MSP430FR5994 don't have DAC);(3)PWM from the Launchpad.  I referred TIDM-VOICEBANDAUDIO  for programming but I couldn't open the .jar file for Audio Loading GUI. I downloaded jarfix and even tried to open with command prompt but none of that is working. 

I don't know how to start programming for audio output, I referred to few more document as Interfacing an I2S Device to an MSP430 Device and tried few example software, but I'm more confused. Can I get some help how should I start programming? What are the available audio library?

MSP430F5659: RTC Month and Calendar Month range conflict

Part Number:MSP430F5659

I just noticed the time in my software is jumping from May 30 to June 1 (Skips May 31).  My hypothesis was that I had a month range error [1-12] instead of [0-11] causing the clock to think its the wrong month and thus the wrong number of days in each month. After testing all of my own libraries, I determined there were no problems.  I then shifted focus to the rtc and calendar datatype, where I discovered the following:

On page 611 of SLAU208P (MSP430F5659 Userguide) the register RTCMON indicates the month range is [1-12]. On page 401 of the mspware driver library users guide (DOCNUM-2.91.03.00) the calendar datatype specifies a month range from [0-11]. Finally, within driverlib/MSP430F5xx_6xx/rtc_b.c, the functions RTC_B_initCalendar() and RTC_B_getCalendarTime() don't account for the month range conversion (See the attached code  and documentation snippets).

It seems like there should be a month translation in the rtc_b functions. Is there merit to my findings, or am I missing something?

void RTC_B_initCalendar(uint16_t baseAddress,
                        Calendar *CalendarTime,
                        uint16_t formatSelect)
{
    HWREG8(baseAddress + OFS_RTCCTL01_H) |= RTCHOLD_H;

    HWREG16(baseAddress + OFS_RTCCTL01) &= ~(RTCBCD);
    HWREG16(baseAddress + OFS_RTCCTL01) |= formatSelect;

    HWREG8(baseAddress + OFS_RTCTIM0_L) = CalendarTime->Seconds;
    HWREG8(baseAddress + OFS_RTCTIM0_H) = CalendarTime->Minutes;
    HWREG8(baseAddress + OFS_RTCTIM1_L) = CalendarTime->Hours;
    HWREG8(baseAddress + OFS_RTCTIM1_H) = CalendarTime->DayOfWeek;
    HWREG8(baseAddress + OFS_RTCDATE_L) = CalendarTime->DayOfMonth;
    HWREG8(baseAddress + OFS_RTCDATE_H) = CalendarTime->Month;
    HWREG16(baseAddress + OFS_RTCYEAR) = CalendarTime->Year;
}

Calendar RTC_B_getCalendarTime(uint16_t baseAddress)
{
    Calendar tempCal;

    while(!(HWREG16(baseAddress + OFS_RTCCTL01) & RTCRDY))
    {
        ;
    }

    tempCal.Seconds = HWREG8(baseAddress + OFS_RTCTIM0_L);
    tempCal.Minutes = HWREG8(baseAddress + OFS_RTCTIM0_H);
    tempCal.Hours = HWREG8(baseAddress + OFS_RTCTIM1_L);
    tempCal.DayOfWeek = HWREG8(baseAddress + OFS_RTCTIM1_H);
    tempCal.DayOfMonth = HWREG8(baseAddress + OFS_RTCDATE_L);
    tempCal.Month = HWREG8(baseAddress + OFS_RTCDATE_H);
    tempCal.Year = HWREG16(baseAddress + OFS_RTCYEAR);

MSP430F5528: SPI communication with an XBEE

Part Number:MSP430F5528

Hi everyone,
In my project, I want to read the flow data using the TDC1000-TDC7200EVM and send these data to an Digi's XBEE PRO S2C, exactly the same as the following thread:
https://e2e.ti.com/support/sensor/ultrasonic/f/991/t/660329?TDC1000-TDC7200EVM-Send-output-from-TDC1000-TDC7200EVM-using-RF-Modules-without-the-use-of-GUI-and-connection-between-the-board-and-a-PC

I know that it's possible using the SPI bus coming out from the MSP430, but I have some questions about it:

1) The XBEE module is powered with 3.3V, so the SPI also requires 3.3V signals. The SPI bus from MSP430F5528 would be directly compatible with the XBEE's SPI? Or it would be necessary to convert the signals levels (using a voltage regulator for example)?
2) Is there any code for MSP430F5528's SPI communication avaible? I'm new to the MSP430 and I don't know where to start.
3) To write and compile the code should I use the Code Composer Studio? And to program it in the MSP430F5528 should I use the BSL loader? Is there anything else needed to accomplish what I want?
4) In the thread I mentioned above, it says that I can use any of the unused GPIO on the MSP430 as CS, but how do I configure any of these GPIOs to work as a CS?

I'm a begginer in this area, so I would be very grateful if someone helped me in these initial steps.

Best Regards,
Lucas

There is no problem if I create a new project.
the problem is only in the working project.But because this is company project, I can't share it to public to you.

They are not sure if it is normal or not. Or any software tips for this?

Hi,

I am working with a Smart Energy Meter design with MSP430F6779A micro controller. As per the smart meter specification ,it's mandatory to have a remote firmware update(OTA) provision.  From my understanding, as we are using MSPF6XX series , BSL can be modified for our requirement. For our requirement the new image will be downloaded to a SPI flash , after successful download the application has to invoke boot loader and load the new image from SPI flash.

1) Can i Implement this with a custom BSL?

2) Do you have any example addressing this requirement?

Please help.

Dear Sirs,

I am using MSP430FR2033 to acquire ADC value, however I found that my ADC value is "jumping" around 40 step, which is about 100mV.

My ADC input is a power supplier and I also check my VDD is no jitter by oscilloscope. According to my experience on other MCU, the ADC value should be very stable.

When I test this issue, I didn't switch to different channel and get data every 10ms, but still see this issue.

Here is my configuration:

ADCCTL0   &= ~ADCENC;                       
ADCCTL0   |= ADCSHT_2 | ADCON;              
ADCCTL1   |= ADCSSEL_3 | ADCSHP;            
ADCCTL2   |= ADCRES;                        

ADCIE     |= ADCIE0;                        

PMMCTL0_H  = PMMPW_H;                       
PMMCTL2   |= INTREFEN;                      
while(!(PMMCTL2 & REFGENRDY));

Any suggestions ?

MSP430F6726: MSP430F6726 Consumption current increase

$

Part Number:MSP430F6726

Hi community member,

There was a phenomenon that the consumption current of MSP430F6726 was too high on my customer's board.

Looking at the thermography of the board, only the microcomputer had a fever.

So I guess that we are consuming electricity with the microcomputer.

However, I am in trouble because I do not know the cause.

Could you give me some advice?

◆ Phenomenon Environment

Phenomenon board: customer board
Consumption current: 13 mA to 50 mA max
Theoretical consumption current of board: 15uA

◆ Unused pin processing

All unused pins are set to Low output setting (PxDIR.y = 1, PxOUT.y = 0)

◆ Symptom situation

The microcomputer's operation was normal even on boards with high current consumption.
If reset input is made to the reset terminal, consumption current may become about 15 uA.

Consumption current is high right after power on.
Especially this phenomenon is easy to occur if it is a new battery.

◆　Circuit diagram

The circuit diagram around the power supply is as follows:

Batteries are connected directly to microcontroller, peripheral circuit Vcc.
battery:Cell Type CR17335E-R

◆ Thermography image

Best regards.
