MSP432-RTOS: Multibyte receive issue on UART using TI-RTOS

August 11, 2017, 2:12 pm

Part Number:MSP432-RTOS

Hi Team,

In my project I have connected the UART (UARTA2) to pulser unit to get the samples from pulser. This is required as that is the only way this pulser unit is able to transmit data from itself.

Certain commands sent to pulser send one byte information back. but there are couple of commands sent to pulser which sends 4 byte and 1024 byte of data back.

I have been trying this out since over a week now but not able to get a solution for the problem.

When pulser sends 1 byte of information the MSP432 UART is able to receive without any issue.

However, when the pulser sends 4 bytes or the 1024 bytes of data the MSP432 is not able to capture that data.

I am using the "simplelink_msp432_sdk_1_40_00_28" version and have built the code based on RTOS where UART write is called continuously and the UART read is interrupt based using the Read Callback concept.

If I try to copy the bytes received in the UART read callback function into an array so as to free the RXBUF the interrupt never occurs and I don't receive anything in the receive buffer than afterwards.

The reason why I am copying into buffer is as I also get overrun flag triggered when the pulser sends more than 1 byte of data.

Please provide your guidance.

Thank you

Vikram

Hi anyone，

I use the MSP430F5529 USB upgrade using built-in BSL, can achieve the upgrade is the current firmware and target hardware is matched, if do not match does not upgrade？


Because I may use 5529 to do different equipment, all upgraded through the USB, if the upgrade mess, will lead to the program does not match the device after the upgrade.
I read the BSL's PC-side code, did not see such a thing, can achieve my needs?

Below code is the working solution that occupies the RAM, however, when I tried to move it to FLASH using the pragma, the value is not correct (ie read 0xFFFFFFFF)

What further step I could take to force the array variable to reside the FLASH?

     char*   sTERMCommand;

struct EDS_List ODList_Generic [] =     // Need to be placed here above the  myFunctionCallSwitch
{
    {   "LOGGER_$H",                                    zVOID                               }

Hi. I can't get the Serial Monitor to work in Energia. I have read some other threads (closed) but the information from there leads didn't help me.

I have a Rev 1.4 board.

I have tryed RXD/TXD without jumpers, with vertical jumpers and horizontal jumpers.

I have unistalled all drivers and try again. I must solve the DPInst.exe issue first, because included is a 32 bit version.

But upon getting a 64 bit version, it says that the included driver is not better than the one in the system: Texas Instrument (usbser) Ports (12/11/2007 1.3)

I am using a Windows 10 Home 64 bits

Thanks for the help, folks.

By the way, newest version of Energia (18, aka 1.6.10E18) does not work.

MSP-FET: Are the new batch of FET's defective.

Part Number:MSP-FET

Hello,

I recently fried one of my older MSP-FET430UI tools, and decided to a get the new - MSP-FET, so I recently purchased two MSP-FET from both mouser and digikey.

Neither will connect to my boards which use processors MSP430G2231, or MSP430F2013 with bispi.  I have yet to try out other processors.

When I use an older FET: MSP-FET430UI and it works fine - no problems.

When I swap in the new FETs that I recently purchase they will not connect. I believe that there is a problem with your the new FETS.  Perhaps it's a manufacturing issue, or maybe some sort of compatibility issue. 

I am using CCS version 7.2.0 the latest.  The Fet has a Serial Number: 1705001ECW.

Has anyone else gotten this new batch of FETs to work with these processors?  Should I return the tools, and wait for the next batch, and hope TI will fix the problem?

Thanks,

Tim

msp430fr4133: capacitive differential measurement?

Part Number:msp430fr4133

Dear,

I have a one-pin capacitive measurement working for msp430fr4133 and free pins around ;)

However, instead of capacitance relative to ground, I would like to measure the capacitive change between two plates of a coplanar capacitor :)

This is "easy" with msp430fr2633 or fdc* IC but I would like to avoid them.

So, for this, should I simply substract the difference between two independent measurements?

I guess not so, which is your suggestion?

Have a nice day :)

MSP430G2553: Doubt in the calculation of the effective capacitance for an external crystal oscillator

Part Number:MSP430G2553

Hello,

I am designing a PCB with the msp430g2553 and an external crystal oscillator of 32 KHz with load capacitors of 12.5 pF (www.farnell.com/.../14221.pdf. I am following the design criteria of the document www.ti.com/.../slaa322d.pdf. In an example on page 4 (2.1 Effective Load Capacitance), the load capacitance is calculated and the value is 22 pF but that value can not be obtained with the programmable capacitance of the microcontroller (only 1, 6, 10, 12.5 pF). So, do we have to add external capacitors? Thanks in advance.

Best regards,

CCS/MSP430FR2311: MSP430FR2311

Part Number:MSP430FR2311

Tool/software: Code Composer Studio

Hi,

I started to program the MSP430FR2311 that I intend to use as RC5 remote control.

The first thing I bumped into is that I cannot get the device run at 8MHz properly.

I initialize the CS registers as follows.

/*

* Clock System Registers:

*/

CSCTL1 = DCORSEL_1 + DISMOD; // select DCO to run at 8MHz.

//CSCTL3 = SELREF_1; // use REFOCLK for DCO input

//CSCTL4 = SELA; // ACLK = REFOCLK (32.768KHz), DCOCLKDIV is source for MCLK and SMCLK

//CSCTL5 = DIVS_1 + VLOAUTOOFF; // MCLK = 8MHz, SMCLK = 4MHz, VLO off when not used

As you can see did I commented out CSCTL3-5 to understand the function of the DCORSEL value.

If I program it for 2MHz, (DCORSEL = 001b) as the default POC value is, I get a MCLK frequency of 1.03MHz, which is OK (within tolerance?)

If I change the DCORSEL value to 8MHz (DCORSEL = 011b), the MCLK frequency stops at 3.44MHz.

I measure the output frequency by setting up timer_0B as div100 counter and measure the output frequency at pin P1.7, which is 1/00 of MCLK/SMCLK

I checked the CS registers and found that in CSCTL7 the bits indicate a DCOERROR, DCO out of range.  Below the register readouts for 1MHz and 8MHz setting

DO you have an idea what I am doing wrong here?

1MHz setting CS register values

8MHz setting CS register values

Hello,

While looking MSP430FR6972 code examples, i noticed that P1.5 was assigned as UCA0CLK. However, P2.2 can be assigned according to datasheet.

P1SEL1 |= BIT5; // USCI_A0 operation
P2SEL0 |= BIT0 | BIT1; // USCI_A0 operation

Is there any special reason for that? Can we use P2.2 too?

Hello:

         I have find two bugs in the demo included in the CCSv7:

First:

   The demo is located in:

       CCSv7->View->Resource Explorer->Software->MSP430Ware-v：3.60.00.10->Development Tools->MSP-CAPT-FR2633->Demos->CAPTIVATE-BSWP

     Test hardware platform:  CapTIvate MCU Development Kit      MSP-CAPT-FR2633

      This demo's bug is that the watch dog can't be stopped. The WDTHOLD bit is always be reset. In my opinion to ways to solve the problem: (1) replace the code "WDT_A_hold(WDT_A_BASE)" by "WDTCTL=WDTPW|WDTHOLD"(2) update the driverlib.lib ,I have build a new static library which include all the documents in the folder named "MSP430FR2xx4xx",and the problem have been solved.

Second:

        The demo is located in:

CCSv7->View->Resource Explorer->Software->MSP430Ware-v：3.60.00.10->Development Tools->MSP-EXP430FR4133->Demos->Out of Box Experience

       Test hardware platform:MSP-EXP4133   Rev 1.0

      This demo's bug is that it can't realize the function which is designed. The reason is in the warnings of the ccs when build the project.

I have a windows 7 laptop sent to me from my customer who is using the MSP-FET430UIF debugger to program Bluetooth firmware into a device on their board. I tried to purchase the MSP-FET430UIF from TI, but was told it was obsolete & would need to purchase the direct replacement MSP-FET debugger. I purchased this debugger, and tried to use it with the laptop containing the software my customer provided. The laptop recognizes the debugger on COM11 of the pc, but I get an error when the mps430flasher.exe utility tries to set the VCC to 3000mV. The old tool, MPS-FET430UIF works fine on this pc.

Please see the attached screenshot, which shows the batch file that is invoking the debugger software. Can anyone help me get this "compatible tool" working on this pc?

MSP430FR5739: Entering ROM Bootloader during program operation

August 14, 2017, 1:20 pm

Part Number:MSP430FR5739

I have an MSP430 design that uses a UART for communication.  If the user sends the right command to the UART, I would like to kick it into the ROM bootloader.  The c code that I use to do this is:

__delay_cycles(2000000);
ClockDriver_SetClockForBootloader();
__delay_cycles(2000000);
__disable_interrupt();
((void (*)())0x1000)();

This will change MCLK to 8 MHz (which the bootloader user guide says is required) and then call the jump instruction.  I lose connection to the UART when I execute this, but I'm not able to ever talk to the bootloader.  However if I call these exact lines of code at the very beginning of my code, I jump to the bootloader and I'm able to talk to it just fine.  I am using different baud rates (57600) vs what the bootloader uses 9600 but I did try changing my own baud rate to the bootloader baud rate (and using even parity like the bootloader) but that did not work either.  Any thoughts on other things to try?  I really want to not rely on the hardware entry sequence to talk to the bootloader.
