Part Number:MSP430G2332

Hello,

I need to know how long the device can survive under the following condition:

MSP430G2332 transmits a 2.2V signal on PIN 13 (P2.6) (Configured as Output) to another controller. However, the controller is not powered up when it sees this 2.2V signal, and this signal powers the controller through the ESD Diode. This pulls the PIN 13 on MSP down and we see a dip from 2.2V to about 1.5V for about 200us.

This condition occurs 50 times a day approximately. How reliable is the MSP430 when it is subject to 

Thanks.

Part Number:MSP430F5229

I have been working with the audio sink board with the MSP430f5229. I have the A3DP demo project running on the board. I modified the HFP demo (as a headset) project to allow it establish a Bluetooth connection and answer/hang up calls without the command line entry and got it to run on the board. Now, I would like to have HFP and audio sink run together and it doesn't fit in the MSP430f5229. I will be using momentary push buttons so I don't need cap touch buttons. Is there a device available (or something in the pipeline being released soon) with the smaller DSBGA package (MSP430f5229IYFF 64 pin) that would have 256 kB of flash so that I can run the Bluetooth profiles I need (A3DP, AVRCP, HCI, HFP WBS)?  I don't have a lot of space which makes the DSBGA package attractive as well as the cost.

thanks,
Kim

Hi,

I have a msp 432 which most of the time sleeps.

But when it wakes up it has to send some data as fast as possible over mobile network(UART) interface.

The uart is working perfectly at 115200 speed but if I try to a higher speed like 230400 it hangs. It is even possible to set this speed for the uart  at 48M clock.

Thank you for the help

Feels like this should be a pretty easy problem to solve but it's giving me a headache. 

I have an MSP430F5529 launchpad with 7.5kohm resistors being used as pullups from 3V3. When I run the code and connect SDA and SCL directly to an oscilloscope, both SDA and SCL are held high.

I already found out that Wire.endTransmission() causes a hold up in the code so I commented it out. Also, when I leave in all the serial.print commands I can see based on the monitor that it is looping through the loop().

#include <Wire.h>

byte idle = 0x00; // Tidle min = 4 clk pulses but can be longer

byte Start =  0x05;
byte TIDhigh =  0x02;
byte TIDlow = 0x03;
byte CNTL =  0x7D;
byte CPTY =  1;
byte D1;
byte D2;

void setup() {
  
  Serial.begin(9600);           // start serial for output
  delay(100);
  Wire.begin();

}

void loop() {

  DataFormation();

/*
  Serial.print("D1: ");
  Serial.print(D1, HEX);
  Serial.print("\n");

  Serial.print("Start: ");
  Serial.print(Start, HEX);
  Serial.print("\n");

  Serial.print("TID: ");
  Serial.print(TIDlow, HEX);
  Serial.print("\n");

  Serial.print("CNTL: ");
  Serial.print(CNTL, HEX);
  Serial.print("\n");
*/
  
  Wire.beginTransmission(0x03);
  Wire.write(Start);
  //Wire.endTransmission();
  
}

void DataFormation(void) {

  byte temp;
  
  D1 = Start;
  temp = (D1 << 3) | TIDlow;
  D1 = (temp << 2) | (CNTL >> 6);

Hello master,

From the MSP430FR6972's user guide (Page 107), I got SCG0 bit's description "System clock generator 0. This bit may be used to enable or disable functions in the clock system depending on the device family; for example, FLL enable or disable " . However , I don't find FLL 's informations from user guide any more , except the part for descripting SCG0 bit. What is FLL for ? Do the  MSP430FR6972 have FLL function ?  Do the LPM0 and LPM1 's  functions be same in the MSP430FR6972 ? Also , LPM2 's function is same to  LPM3 's function ?  

Best regards

Part Number:MSP430F47187

Hello All, 

I am trying to interface a Microchip NOR flash (SST25VF080B) to the MSP43047187 on SPI port (USCI B1) . 

The same port was originally interfaced to an SD card. Pins used are P2.1, P2.2, and P2.3.

Currently the SD card holder has not been mounted , although the pull up resistors (10K) on all lines are in place.

I am using SPI in the 3 pin mode. The CE#  and WP# are derived from P1.3 and P1.4 in my hardware and bit banged when required. 

My problem is I am not able to initialize the SPI bus itself. I do not see any activity on either the CLK, SIMO or the SOMI pins. Only the Enable and WP pins get toggled since they are bit banged. 

Initialization code is attached below.

 I want to know the advantage of DMA in energy consume. But the datasheet do not give the DMA module current consumption like below:

Do anyone have the specific data for DMA?

What’s more when the DMA works the CPU has been halted in low-power mode as the user’s guide said as below:

And I don’t know the specific current of CPU in this mode.Does anyone have the specific data?

Part Number:MSP430F67751A

Hi Everyone,

We are using MSP430F67751A for our application. In this we are giving clock using an External Clock using TCXO (32768 Hz).

I wanted to calculate the exact Main Clock and Sub Main Clock. So I have used the following formulae from User Guide to calculate exact clock output from PLL.

 From that calculation , I have Found MCLK and SMCLK which is shown below.

It is not exactly 16Mhz.

Also calculated the DCO thermal and Vcore Voltage drift for that SMCLK from DCO , that shows around

is the above clock drift is acceptable ?? in ppm it is around 30950 ppm for the clock of 16023552 Hz. (Please Refer the attachment for the detailed Calculation)

Kindly Clarify it .

eUART Tx error : 

Also I have Calculated eUART Maximum Tx Error for this worst case SMCLK (from the above table ) and it shows the Tx error of maximum 25 % . (Please Refer the attachment for the detailed Calculation)

Is it acceptable for the successful UART communication ??

Kindly give if you have excel calculator for the Tx and Rx Error for eUART ..

Thanks and Regards ,

Hi 

I am using eUSCI_A0 UART. The baud rate is 115200

If I use external TCXO, HCMOS, 3.3V, 14.7456Mhz for eUSCI_A0 clock, 

BRCLK = 14.7456Mhz, OS16=1

N = fBRCLK/baud rate = 14.7456e6/115200 = 128

 UCBRx = INT(N/16), = 128/16 = 8

UCBRFx = INT([(N/16) – INT(N/16)] × 16) = 0

then 

BITCLK time  = (1/BRCLK)*N/2 = (1/1475600)*128/2 = 4.34us or BITLCK = 0.2304Mhz which is 1/64 times BRCLK

Will baud rate be accurate.

My Customer is having trouble hitting the 1 msps (actually needs 600khz) rate over 3 channels using the DMA.  

I’m working to get the ADC14 running at 200 kSPS per channel, alternating between 3 channels for a total of 600 kSPS. I’m running at 48 MHz, have the ADC samples being triggered by TIMER_A, cycling between 3 analog channels. I’m close to 600 kSPS rate using just using ADC interrupts & no DMA, but am missing samples, as expected. I started this way (without DMA) to get my input lines, clocks, & ADC doing what I want. Now, I’m trying to fold DMA into the mix.

I need DMA to handle 2 transfer scenarios:  (1) Directly into the SPI TX, and (2) Directly into a local RAM array (for pre-processing steps before SPI transfer).

I have scoured the Project|Examples|Resource Explorer, and don’t see anything this complex. Are there other sources of examples?

Apparently, there’s only 1 DMA channel that supports being triggered by the ADC (DMA Channel 7). If I’m sampling 3 channels (A0-A2), the DMA gets triggered after all 3 are scanned, so 3 transfers occur and the DMA interrupt goes off. Then, in the DMA interrupt, I have to update the destination address to move 3 entries down. This takes too long, so am missing samples.

What speed are you running the processor?     [48 MHz]

What resolution are you running the ADC?       [14-Bit]

What is your ADC14CLK?  [24 MHz]

What is your ADDC 14PDIV? [I don’t know what this is; Using ADC_DIVIDER_2) 

What clock Source are you using?  [MCLK]

SLAA707.pdf appeared relevant, but upon review was not useful to the customer.

Code available on request for internal review.

Hello, 

i am working with Captivate Design Center and tried to write the code to a CapaTouch Sensor to regulate the light of a LED. 
While I was succesfull realising to start the PWM signal for the LED with the touchsensor i am not able to realise a timer (in the Code: TIMER_A1_BASE) to make the duty cycle of the PWM signal time-dependent. My idea was to start the timer (like the PWM signal) as the apphandler is running and with every overflow of the counter the dutycycle should increase by 5. 
While the PWM signal is running as soon as i use the touchsensor, the timer i started in the line before doesn't seem to run. There isn't even 1 interrupt triggered to increase the duty cycle. 

Now my Question is: Did I falsely generate the timer or is the any issue with the interrupt?

I under stand that the BSL Signature (0xFF84-0xFF87) can be set, and that if/when one wishes to use the BSL to interface to the part, one must supply a password that matches this signature.  (If I am wrong here, tell me.)  I understand that one signature (0x5555_5555) disables BSL, and other signatures erase the FRAM on a wrong password etc.  I can not determine from SLAU445G (See Table 1-5) or SLAU55I (and others) what the default signature is or how to set it, only where the signature is stored.

If my understanding above is correct, my questions is, how does one set the BSL signature in C code?  I assume it involves some compiler directive (dir-ec-tive -- shades of Wall-e) but the ones I have tired (e.g., location) were not accepted by CCS7.

(By-the-way, it appears that SLAU550I, Table 1, does not address the FR2532, but does come close.)

Hi,

I recently installed IAR and MSPFlashProgrammer from Elprotronics. After connectin the MSP-FET to my computer, I launched Elprotronics SW first, and it asked if I wanted to upgrade the FET FW to match, and I chose yes, and this was my mistake :(.

Now the IAR SW will not work with the FW of the FET, however it will also not trigger the upgrade FW. I get the "can not set device voltage"/"failed to set VCC voltage" errors.

Could anyone please tell me how I can downgrade the FW to force maybe FW upgrade, or how I can upgrade the FW on the FET to work with IAR?

thank you,
