  • Forum Post: Re: ask some question about TimerA

    DerekC
    supercuate, May I ask what you are trying to do? With Brandon's implementation j will always equal i, therefore the condition j==i will always be true and the LED will toggle when i == 10 and when i == 20. Also I notice j is not initialised. Derek

    Hi all, I'm a relative newbie with the MSP430. After 5 days solid debugging, and googling, I'm beginning to get to know the 430 and IAR IDE. - My wife thinks I'm getting to know it too well! I'm playing with a software RTC on the Olimex MSP430-4619LCD development board connected to...

    Hello all, I'm working with a msp4302410 and I need to config USCI0_A as UART and USCI0_B as I2C master. I think I'm almost done but I have a doubt, the two modules share the same TX and RX interrupt so it seems to me that I need to check in the ISR the source (A or B). Am I on the right track...

I already have it sending out a square wave to two LEDs, but I need it to receive and sample two analog signals from two photodiodes while the LEDs are lit up. It's mostly...

    Td SD16INCTL0 = SD16INCH_0; // A1+/- Hmm, SD16INCH_0 references A0 (P1.0), not A1 (P1.2). It should be SD16INCH_1 instead. Also, you don't select P1.2 for use with the SD16 (P1SEL|=4). Also, you use the SD16 inputs (no matter whether A0+ or A1+) as LED outputs. Better use A3+ (P1.6). Or may it...

    Garry Barton
    I read in the users guide while the MSP430 is in the interrupt service routine then further interrupts are disabled. What happens if during the ISR anthother interrupt happens? Does the interrupt get handled when the ISR completes or is it lost?

    Thank you for your reply. In order to simplify the debugging, I removed all communication with the F2013 and am just incrementing the value to display to the LCD withing the for(;;) loop. And for testing purposes, I also removed all reference to LPM0. Now I never reach the breakpoint I placed inside...

    I think I finally got the code (see below) to do what I want - i.e., for the LCD to continuously display values communicated from the F2013 until 15 sec. have passed, at which point the LCD "times out" for several seconds. It took a while to understand how LPM and the ISR were behaving. If...

    Steven, because you didn't mention it, i am assuming that you are using CCSTUDIO or IAR EWB. Basically the answer is yes, you need to put the #pragma vector directive before any ISR. The name of the vectors are defined basically in the header file of the MSP430 devices, so you shall not change...
