    BrandonAzbell
    Have you looked at the code examples (SLAC166) provided on the MSP430F5438 Product Folder ? There are a couple of examples that configure the USCI for UART mode and use LPM0 and LPM3. They do use a different targeted baud rate, but this should provide some guidance. I realize this isn't a definitive...

    milanqingren msp430f149 has 60KB + 256B flash. So, a 16bits pointer should be able to handle all of flash memeory spaces. However, msp430f5438 has 256KB + 512B flash memory, which introduces more than 16bits memory spaces. Therefore, how do I do deal with the memory spacing problem? Can I just use...

    Hi There, The 5xx Experimenter's board (link: http://focus.ti.com/docs/toolsw/folders/print/msp-exp430f5438.html ) has a 3-axis accelerometer on the board, and there is demo software that utilizes this chip that could be modified to accomplish this task.

  • Forum Post: Re: MSP430x5438 USCI numbers

    BrandonElliott
    Each USCI has two channels, A &B. Channel A supports UART, IrDA, LIN, and SPI while Channel B can support I2C and SPI. Therefore, if a customer is looking for 2 UART channels, the MSP430 should have at least 2 USCI modules. However, if they are looking for two SPI channels, 1 USCI module is enough...

    BrandonElliott
    Please note the specs for the temperature sensor, figure 17 and Note 2 on page 62 of the datasheet . Essentially the temperature sensor can require a 1-point calibration to get a semi-accurate value, since the temp sensor can be as much as 20 degrees off initially (mentioned in Note 2). In my experience...

    Hi, I'm wondering where the interrupt vectors are specified. From the example code for the F5438 device I can find the following vector: // Timer A0 interrupt service routine #pragma vector=TIMER1_A0_VECTOR __interrupt void TIMER1_A0_ISR(void) { P1OUT ^= 0x01; // Toggle P1.0...

    Hi, There are a few references that can help you understand the function & scope of each interrupt: 1. The User's Guide: At the end of each chapter the interrupt scheme is described, and in the systems chapter the types of interrupts are specified. This is the primary document to refer to...

    The definition of the TIMER1_A0_VECTOR and TIMER1_A1_VECTOR are found in the msp430x54x.h header file which should be included in the *.c file this code is found in. You will find the other vectors defined in that file as well. In general, when asked where a symbol is defined, I generally do a search...

One for the CCIFG0 and one for the CCIFG[1-6]. Also, in the MSP430x5xx Family User's Guide ( SLAU208 ) in Section 13.2...

    Al, You definitely should not see current consumption so high. What peripherals are you using? Are you using a custom board? I recommend running a example code ( www.ti.com/msp430codeexamples ) and see if the current consumption is reduced. If the problem goes away you can focus on software, else...

    FYI the chips with BSL disabled are the experimental "XMS" chips. If your top-side markings have XMS430... instead of MSP430 then your BSL is disabled! Order or sample a newer revision.

  • Forum Post: Re: MSP430F5438 false breakpoint hits while debugging

    BrandonElliott
    How many breakpoints are you using when this happens? When you say it's stopping in the ISR is there a breakpoint in the ISR? If so this could be a timing issue. The debugger utilizes the embedded emulation module of the MSP430. This element controls only the CPU. Now, the Timer is a hardware peripheral...

    Hello. I made the same observation as described above. The examples are not helpfull in this case, as mentioned earlier. They do not address a comparable scenario (8MHz SMCLK, 115.2kBaud, LPM3). SMCLK remains active although it should be off in LPM3 when no other module is requesting the SMCLK and...

  • Forum Post: Re: MSP430F5438 -- UART interfering with ADC

    BrandonAzbell
    It is unclear what issue you are having, but I would suggest not having the call to Xbee_Command() within your ADC interrupt service routine. While you are in the interrupt service routine, the Global Interrupt Enable is "disabled", therefore no other interrupts will be recognized and serviced...

    I am sorry, I was trying to explain my code and forgot to explain the real problem. The thing is that when I initialize both the ADC and the UART, my code will never enter into the ISR. If I initialize the UART and comment out the ADC code, then I can send all the commands I'd like. If I comment...
