CCS/MSP430FR2111: Controller resets after 20 seconds, watchdog diabled.

Part Number:MSP430FR2111

Tool/software: Code Composer Studio

Hello,

i am using the MSP430FR2111 to read ADC values after some time of waiting in LPM3. I am using Timer B0 interrupt to wake up. The ADC also uses the interrupt.

Everthing works fine (LED´s blinking, ADC_Result fill´s up with data) until the controller resets after about 20 seconds. The data in ADC_Result is erased and the ADC starts again writing in position 0.

I tried several things, but nothing helped.

I am using CCS 7.2 and the MSP430FR2311 LaunchPad to program my own MSP board.

Here is my code:

#include <msp430fr2111.h>

unsigned int Counter = 0;
unsigned int i = 0;
unsigned int ADC_Result[60];

void main(void) {
WDTCTL = WDTPW + WDTHOLD; // Stop WDT

P1DIR |= 0x03; // Set P1.2 to output direction
P2DIR |= 0x01; // Set P2.0 to output direction
P2DIR |= 0x02; // Set P2.1 to output direction
P1OUT = 0x00; // Set P1 outputs low
P2OUT = 0x00; // Set P2 outputs low

PM5CTL0 &= ~LOCKLPM5; // Disable the GPIO power-on default high-impedance mode
// to activate previously configured port settings

// Configure ADC10
ADCCTL0 |= ADCSHT_2 | ADCON; // ADCON, S&H=16 ADC clks
ADCCTL1 |= ADCSHP; // ADCCLK = MODOSC; sampling timer
ADCCTL2 |= ADCRES; // 10-bit conversion results
ADCMCTL0 |= ADCINCH_0; // A0 ADC input select; Vref=AVCC
ADCIE |= ADCIE0; // Enable ADC conv complete interrupt

TB0CCTL0 = CCIE; // CCR0 interrupt enabled
TB0CCR0 = 511; // Timer count compare: 4095 -> 1 sec,
TBCTL = TBSSEL_1 + ID_3 + MC_1; // ACLK, /8, upmode

_BIS_SR(LPM3_bits + GIE); // Enter LPM3 w/ interrupt

for(;;) {}
}

// Timer A0 interrupt service routine
#pragma vector=TIMER0_B0_VECTOR
__interrupt void Timer_B (void)
{
Counter++;
if(Counter == 5) // 1 min 480
{
P1OUT |= 0x03; // Set output P1.2
P2OUT |= 0x01; // Set LED green
}
if(Counter == 6)
{
ADCCTL0 |= ADCENC | ADCSC; // Sampling and conversion start
P2OUT &= ~(0x01); // Clear LED green
P2OUT |= 0x02; // Set LED red
Counter = 0;
_BIS_SR(LPM0_bits | GIE); // LPM0 w/ interrupt
}
else
{
_BIS_SR(LPM3_bits + GIE); // Enter LPM3 w/ interrupt
}


}

// ADC Interrupt
#pragma vector=ADC_VECTOR
__interrupt void ADC_ISR(void)
{
switch(__even_in_range(ADCIV,ADCIV_ADCIFG))
{
case ADCIV_NONE:
_BIS_SR(LPM3_bits + GIE); // Enter LPM3 w/ interrupt0
break;
case ADCIV_ADCOVIFG:
_BIS_SR(LPM3_bits + GIE); // Enter LPM3 w/ interrupt0
break;
case ADCIV_ADCTOVIFG:
_BIS_SR(LPM3_bits + GIE); // Enter LPM3 w/ interrupt0
break;
case ADCIV_ADCHIIFG:
_BIS_SR(LPM3_bits + GIE); // Enter LPM3 w/ interrupt0
break;
case ADCIV_ADCLOIFG:
_BIS_SR(LPM3_bits + GIE); // Enter LPM3 w/ interrupt0
break;
case ADCIV_ADCINIFG:
_BIS_SR(LPM3_bits + GIE); // Enter LPM3 w/ interrupt0
break;
case ADCIV_ADCIFG:
P1OUT &= ~(0x03); // Clear output P1.2
P2OUT &= ~(0x02); // Clear LED red
ADC_Result[i] = ADCMEM0;
i++;
_BIS_SR(LPM3_bits + GIE); // Enter LPM3 w/ interrupt0
break;
default:
_BIS_SR(LPM3_bits + GIE); // Enter LPM3 w/ interrupt0
break;
}
}

MSP430FR2311: Timer B - reset without utilizing CPU

August 4, 2017, 6:29 am

Part Number:MSP430FR2311

Hi!


I am working on a project that involves low-side control of a buck converter. I am wondering if there is a method to reset the timer_B counter with a rising/falling edge of a Digital IO pin. 

I know I can do this with a hardware interrupt to the CPU; however, I am trying to not involve the CPU at all. I need to trigger this interrupt at a frequency of 150khz and a CPU interrupt, although short, would effect my other sensing routines.

Basically, my plan is to have a PWM output from a pin using the Timer B with a 50% duty cycle. Whenever the above reset signal occurs, I want the PWM to start over in the off states. This will allow me to control the duration of the "high state" while keeping the duration of the low state constant:

If I can reset the timer, while I'm above TBxCL1, then I can control the width of on time while having constant off time controller:

Let me know what you guys think. Is it possible?

Regards,

George

Tool/software: Linux

Hello,

I would like to know how can i flash my msp430F5529, I do not have an IDE and i work with gcc and mspdebug.

I developed a program for a board that i tested on my launchpad which i flashed with " mspdebug tilib 'prog $<' " and it worked fine.

then i flashed my board via JTAG with an olimex tiny with "mspdebug olimex 'prog $<' " and it worked fine.

then i decided to close my system and flash with an external USB but i cannot seem to make it work. My Linux system doesn't detect an ACM

Part Number:MSP430i2041

Dear Mates,

I am using a SPI based DAC to control output current of an external DC circuit. The issue I have is that, I can send predefined values, and the output DC value corresponds to it, but when I use the the AC current measured by the MSP430i2041, I only get the maximum output DC current value.Regarding this, I have a few questions:

  1> Is 'rms_current(ph)' the correct variable which contains the measured RMS Current? 

  2> If yes, then what's the variable type? If no, then which variable contains the correct RMS Current measurement, and what's its data type?

Attached below is the bit of the modified example code: 

// line number 239 of emeter-main.c
#if NUM_PHASES == 1
                calculate_phase_readings();
                LED3_ON ();
                  
                  static unsigned long CL = 0x2AAA; //4mA = 0x2AAA, the required offset
                  //CL = CL + (int16_t)(rms_current(1)/1000); // this yields the same result as the bottom one
                  
                  CL = ((int)rms_current(0))/1000; // I have tried a lot of variations, but none seem to work 
                  if (CL > 0xDA8E)
                  {
                    CL = 0xDA8E;
                  }
                  updateCurrentOutput( (unsigned short)(CL)); // function to send data to DAC through SPI
#else
                calculate_phase_readings(ph);
                LED3_OFF ();

Any help would be much appreciated.

Thanks in advance

WDTCTL = WDTPW | WDTHOLD;  // Stop watchdog timer

PM5CTL0 &= ~LOCKLPM5_L;  //Disable Low Power Mode

PASEL0 = 0;

PAOUT = 0;

PADIR = 0xFFFF;

P1REN = 0b00000010;

P1DIR &= ~(BIT1);

while (1){

if ((P1IN & 0x02) == 0x00)

{

P1OUT = 0b00000000; //P1OUT = Pull Up Resistor Configurations (P1 OUT = 0 OUTPUT IS PULLED DOWN, P1OUT = 1 OUTPUT IS PULLED UP)

}

else

{

P1OUT = 0b00000001; //P1OUT = Pull Up Resistor Configurations (P1 OUT = 0 OUTPUT IS PULLED DOWN, P1OUT = 1 OUTPUT IS PULLED UP)

MSP430F5529: UART voltage levels for logical 1 and 0

Part Number:MSP430F5529

Hello,

I tried to figure out what are the voltage values for logical 1 and 0 in the UART interface of the device.
 Voh and Vol are divided in the spec to reduced and full drive strength. what's that mean?

In addition , they divide it to different values of Vcc (1.8V and 3V) and Vss. Specifically, I power through micro-USB cable. isn't it 5V? is there a converter to 3V inside?

my general purpose is to interface SIM900 GSM modem which operates at 2.4-3 V for '1' and 0-0.4V for '0'.

Thank you

msp430F5528: Max throughput of a SPI to USB bridge

Part Number:msp430F5528

Hi,

I can run the numbers of max IO speed, SPI bus speed and theoretical USB Speed, but I was hoping someone could provide me with a max throughput speed I can expect with a 5528 doing nothing but moving data from USB to SPI.  The customer wants to hit 5 mbit.

Full Speed USB should theoretically support 12mbit but with a 25mhz 430 clock, I was not sure we are even close to this theoretical...

e2e.ti.com/.../19746

This link above says worst case of approx 4mbit on the SPI.  Can the 430 keep up moving data from the USB to the SPI at this throughput level - using DMA I assume?

Best Regards, Blake

MSP432P401R: strange verify flash error

Part Number:MSP432P401R

Hey,

I have build my own MSP432 hardware and it used to work great,

But now I have a strange problem with trying to debug the MSP432. When try to use CCS7.1 with the launchpad XDS110 debugger I have a failed to verify flash error. If I use uniflash to write a erase hex file don’t have any problems at all.  

 I tried to Upload the project directly to the MSP432 on the launchpad and that works just fine. So I think it has to be a hardware problem, but then the uniflash shouldn’t work either right?

I also already tried to factory reset the msp432 that dint help either.

The hardware setup I am using now is just a couple of decoupling capacitors and a header for the debug trace.

Greets,

Hi guys,

   I am interfacing the custom keypad with MSP430F5510 using USB protocol. I am using the reference example given in github below link:

But the keypress is happening for every time properly till some time. randomly the controller is hanging (that in the sense it is not coming out from the sleep) so no keypresses are happing. i tried to find out many ways to do it. But in the debug mode i tried hour together with debug sesion. I'm not getting any hang at that time. once i remove debugger and i'm trying as separate, that time i am getting problem like that.

Sometimes even it will work for full day. but by next day end it will get hang. please give some suggestion

Hello

I have bare metal (No Rtos)  application on MSP432.

DMA is set to work with UART RX.

UART communication is just flow of 256 bytes telegram with pause 1 ms between.

I see following scenario.

If DMA has not started to listen at the beginning of a UART telegram, it receives part of it, then wait pause, receives the rest amount to the expected 256 (from another telegram)

and so on..

Question

Whith what command from DAM Module DriverLib can I reset the DMA buffer?

RTOS/MSP430F5659: Clarification required stack peak usage - Task

Part Number:MSP430F5659

Tool/software:TI-RTOS

Hi support team,

Thanks for valuble support

In our firmware design, we have 4 task for communication, Data Handling , Diagnostic ,Watchdog.

 

Scheduling:                             Priority based pre-emptive scheduling

Inter task communication:    Mailbox is used

Mailbox size:                           90 character max

Stack size:                               512 bytes

Firmware Design Analysis:

We checked the stack usage of all task which is in running state (at different stages ) and blocked state in debug mode.

 1.  So at first  we run the device in debug mode and kept breakpoint in 4 places of the Communication task and observe stack peak of all task.

                                            Stack Peak: Communication task - 370 , Data Manager -240 , Diagnostic -380 , Watchdog -122,

 2.  Then  we run the device in debug mode and kept breakpoint in 2 places of the Data Manager and observe stack peak of all task.

Stack Peak: Communication task - 370/470 , Data Manager -240 , Diagnostic - 380, Watchdog -122,

Clarification Point:

1.If we kept breakpoint in Data Manager and run communication task in free running mode. Why communication task ,stack peak reaches 470 bytes?

2. Mailbox also uses stack allocated for the task ?

It is 90% of the stack maximum size allocated. We would like to understand the cause of this behavior.

Kindly provide valuable inputs on the behavior to improvise this condition to prevent unexpected behavior of firmware.

Thanks
