Part Number:MSP430F149

Hello,

i am using msp430f149 controller for my products from long time. Now i need to update some features of my sold product and for that i have developed new program.

Since my all sold instruments  are located at different it is not possible to go at site and program it using MSP-FET.

So from now a day i want to include in circuit serial programming in my all products so in feature i will not face this issue again.

It is possible to program MSP430f149 with UART without using MSP-FET ?

can i download .hex file directly to controller using serial communication without any programming tool ?

what hardware i need to add for this functionality ?   

In ti MCU serial programming from UART is known by which word ? is ICSP or any thing else ?

any help is greatly welcomed...

MSP430FR5994: MSPFlasher unable to access password locked JTAG

Part Number:MSP430FR5994

I was experimenting with locking the JTAG and BSL using the below code with my MSP430FR5994 launchpad board.  Based on my reading of the MSP430FR59xx family users guide [0] (p. 65) I think I should be able to access the device with the jtag password 0x1234 but after flashing my device using MSPFlasher I can't access JTAG and more even with the JTAG password I thought I was setting (0x1234).  I also tried MSPFlasher -e ERASE_TOTAL which some documentation indicates should reset FR5xxx devices even if they are JTAG locked.  That didn't work either I always get the message, "# ERROR: The Debug Interface to the device has been secured" from MSPflasher.  Where did I go wrong, and is my device bricked for good?

#include <msp430.h>

__attribute__((section(".bslsignature"))) unsigned int bsl_signature[2] = { 0x5555, 0x5555 };
__attribute__((section(".jtagsignature"))) unsigned int jtag_signature[2] = { 0x5555, 0x0001 };
__attribute__((section(".jtagpassword"))) unsigned int jtag_password[1] = { 0x1234 };

int main(void) {
    WDTCTL = WDTPW | WDTHOLD;
    PM5CTL0 &= ~LOCKLPM5;

    P1DIR |= (BIT1);

    while (1) {

        P1OUT ^= (BIT1);
        __delay_cycles(1000000);
    }

    return 0;
}

MSP430F1611: Utilising two UART ports on TelosB

Part Number:MSP430F1611

Dear all,

I am currently using TelosB(MSP430f1611), and trying to use both UART ports that are available on the board.

I have configured one UART port correctly, and it can transmit and receive with users via PuTTY. Now I am trying to configure another one, which should be easy but I am kind of struggling because I am trying to modify the code that was given to me which forms serial communication with external device.

I have succesfully completed initating the UART configuration but because the given code was written for MSP430fr4133, some of the commands need to be replaced approprittely for msp430f1611. For instance

void dn_uart_txByte(uint8_t byte){
   while(!(UCA0IFG & UTXIFG0));             // wait until TX buffer ready
   UCA0TXBUF = byte;                        // send byte
}

and now I have modified the code to this,  the below is for MSP430f1611. Is this correct?

void dn_uart_txByte(uint8_t byte){
   while(!(IFG1 & UXIFG0));             // wait until TX buffer ready
   U0TXBUF = byte;                        // send byte
}

Thank you

Kind regards

MSP430F1611: RTC

Part Number:MSP430F1611

Dear all,

I am trying to interface TelosB with external device called smartmesh mote "www.linear.com/.../4330".

Here, the example they used for interfacing to the mote was MSP430fr4133 launch pad which is quite different from TelosB(msp430f1611).

Referring to the code, LCD functions are not concerned at initialising board can be done seperately with my existing code. 

The part I am stuck in with is this part of code:

void fsm_scheduleEvent(uint16_t delay, fsm_timer_callback cb) {
   
   // remember what function to call
   app_vars.fsmCb       = cb;
   
   // configure/start the RTC
   RTCCTL               =  0;
   RTCMOD               =  delay;                // delay (in 32kHz clock cycles)
   RTCCTL              |=  RTCIE;                // enable interrupts
   RTCCTL              |=  RTCPS_0;              // divider /1
   RTCCTL              |=  RTCSS_2;              // clock source is XT1CLK
   RTCCTL              |=  RTCSR;                // reset the RTC
}

Please correct me if I am wrong, but as far as I know for MSP430f1611, there is no RTC library available.

Could anyone direct me how to go about with this?

full code is attached in this post.

Thank you

Kind regards

Hi,

We are using MSP430FR4133 connected to an Accelerometer vis I2C bus.

We are using IAR 8

We would like to use P5 PIN2 and 3  or P8 PIN2 and 3 - please advice which is preferred.

We are trying to use EUSCI library - with no success:

This part pass:

EUSCI_B_I2C_initMasterParam param = {0};
param.selectClockSource = EUSCI_B_I2C_CLOCKSOURCE_ACLK;
param.i2cClk = CS_getACLK();
param.dataRate = EUSCI_B_I2C_SET_DATA_RATE_100KBPS;
param.byteCounterThreshold = 1;
param.autoSTOPGeneration = EUSCI_B_I2C_NO_AUTO_STOP;
EUSCI_B_I2C_initMaster(EUSCI_B0_BASE, &param);

Not clear how to config the physical PINs  (is that correct?)

EUSCI_B_I2C_remapPins(EUSCI_B0_BASE,2+3 );

GPIO_setAsPeripheralModuleFunctionInputPin(GPIO_PORT_P5 ,GPIO_PIN2 + GPIO_PIN3,GPIO_SECOND

This part also pass:

// EUSCI B I2C enableInterrupt(EUSCI_B0_BASE, EUSCI_B_I2C_TRANSMIT_INTERRUPT0 + EUSCI_B_I2C_STOP_INTERRUPT);
// Specify slave address
EUSCI_B_I2C_setSlaveAddress(EUSCI_B0_BASE, 0x0D);//SLAVE_ADDRESS);

//Set Master in TX mode
EUSCI_B_I2C_setMode(EUSCI_B0_BASE, EUSCI_B_I2C_TRANSMIT_MODE);

//Enable I2C Module to start operations
EUSCI_B_I2C_enable(EUSCI_B0_BASE);
 

And then I stock on this line:

EUSCI_B_I2C_masterSendSingleByte(EUSCI_B0_BASE,0x00);

Please advise.

In case you have a [pre[ared example I for MSP430FR4133 I would appreciate that.

Part Number:MSP430F5659

Hi,

Is there any timing waveform describing USB BSL sequence covering the following:

  1. Minimum time duration required for PUR pulled high to reset# released.
  2. Minimum time duration required to remove PUR before BOR after flashing the user image.
  3. Minimum duration for generation of VUSB(3V3) after providing VBUS. 
  4. Minimum duration for external VCC to PUR pulled high. 

I could find the BSL sequence in the following  : "http://www.ti.com/lit/an/slaa452c/slaa452c.pdf". But could not find any timing parameters mentioned in this document. Can anyone help me in finding the required information?

My latest PCs do not have a parallel printer connector for Olimex JTAG debugging. 

I find some USB to Parallel printer adapters, but I assume these are just wiring adapters that do not create an LPT1 port.  Looks like they may be part of the solution.

So, is their a solution that connects the latest IAR software to the Olimex MSP420F169 board using the LPT1 connector?

Thanks,

Good Morning TI community!

As you can see from the title I have some problems to install the suggested patch for the IAR 4.50.2 version to support MSP-FET Flash Emulation Tool.

I downloaded the patch for IAR from this link:

but when I tried to install I have this problem:

The warning message is very strange for me because in the specified directory I have the 430 folder (as you can see below) so I don't understand why I have this message.

How can I do if I don't want to do the update to the latest version of the IAR IDE?

Thank you very much for your help.

Hello,

     I want to count number of pulses of encoder on high to low edge triggered on port pin ( rising edge) using MSP432. I have taken variable "a"  in interrupt. when interrupt is occurred on rising edge my count is increment by 1. but my interrupt is triggered on both edge. i got pulses 1000 as i expected is 500 only.

The program is shown below:-


int a = 0;

void main(void)
{
WDT_A->CTL = WDT_A_CTL_PW | WDT_A_CTL_HOLD; // stop watchdog timer

P6->DIR &= ~BIT0; // set P6.0 as a input direction
P6->REN = BIT0; // Enable pull-up resistor
P6->IFG &= ~ BIT0; // P1.4 IFG cleared
P6->IES &=~ BIT0; // high to low
P6->IE |= BIT0; // P1.4 interrupt enabled

// Enable Port 1 interrupt on the NVIC
NVIC->ISER[1] = 1 << ((PORT6_IRQn) & 31);

// wake up on exit from ISR
SCB->SCR &= ~SCB_SCR_SLEEPONEXIT_Msk;

for(;;){}
}


// Port 1 interrupt service routine
void PORT6_IRQHandler(void)
{
if(P6IFG & BIT0)
{
a=a+1;
}
P6->IFG &= ~BIT0;
}

Hello the community, I need you advice ! I don't know really MSP430 series

I have a project but I need you advice to choose the best microcontroller in relation of the price.
Below my specifications :

- low power consumption ( the controlleur wake-up two time a day for 20 seconds)

- I need 4 capacitives touch

- internal RTC to manage and calculate time every time the controller wake-up ( calculate sun set and sunrise hours ). offset 5 to 10 minutes by year

- manage a H bridge ( it's my own H bridge) for drive a DC motor . I need 1 PWM Output and 1 Digital Output for direction.

- 3 analogs input ( 10 bit definition max) to measure a LDR/ motor stall / battery level

- Manage a TFT 1.44 display ( ST7735 ) thru SPI

Last question : do I use Energia or CCS ? ( don't know in regards with the complexity of the program , debug etc .... )

Regards

 My first choise : MSP430FR2532
