  RE: CCS/MSP430G2231: compare two frequencies

  I don't see why not. You'll need a "trigger" of some sort to indicate that the frequency is changing. The multiplexer selection pins might be useful for this if you can reach them. Or maybe a button push. You'll presumably want...

  RE: MSP430G2231: Retrieving Data from USISRL w/ I2C Slave

  Hi Bruce, Thanks for the tip. I tried moving the pointer's assignment to the startI2CSlave() function but I did not see any change in behavior. I also tried moving the assignment to the pointer's declaration but did not see any change there...

  RE: CCS/MSP430G2231: Phase shifting PWM

  Hey Katie, Do the PWMs every need to change frequency? Are they always 50% duty cycle, or does the duty cycle need to change as well? Looking at the timer on that device, generating 2x PWMs is going to be quite difficult especially with only 2 capture...

  RE: CCS/MSP430G2231: 555Hz PWM with 0.05% DC

  Per data sheet (SLAS694J) Table 22, TA0.1 (for TA0CCR1) is available on P1.6. Try using LPM0_bits rather than LPM3_bits. I'm pretty sure SMCLK is turned off in LPM3.

  RE: CCS/MSP430G2231: P1.3 button not working

  If you still have the box the Launchpad came in, I encourage you to dig down to the bottom to see if there's a G2553 there. The G2553 has more pins, and is generally much more capable than the G2231, but there's enough functional overlap that...

  RE: CCS/MSP430G2231: MSP430G2231

  2) MC0/1 are bits in a two-bit field. I suggest you use MC_2 (Continuous) to set the field and (~MC) to clear it. 1) You won't succeed in measuring 10MHz using capture, since even at top CPU speed (16MHz) that gives you only 1.6 CPU clocks to process...

  RE: MSP430G2231: MSP430G2231pin 10 and 11

  Pins 10-11 are the Spy-Bi-Wire (program/debug) pins, and not available to the GPIO. Pin 10 can be configured as a Non-Maskable-Interrupt pin, but that is a very restricted usage.

  RE: Compiler/MSP430G2231: CCS "MSP430 Flash Settings" not available

  Problem solved. Bruce pointed out that someone had forgotton to add the setting, but it is back in CCS version 9, as Peter pointed out. I have installed V.9 and I am back in the running. Thanks.
