Hi Nima, Managed to reach pulse width of 8 microseconds in 1 Hz PWM by using up-down mode. Can I use hardware resolution to generate even smaller pulse width? Thanks and Regards, Ankit

Forum Post: RE: MSP430FR2311: RTC Interval Incorrect
I believe that line of code tells it to use ACLK instead of SMCLK. I'm assuming this based on Figure 6-1 www.ti.com/.../msp430fr2311.pdf So by the figure I'm assuming with SYSCFG2 RTCCKSEL set, it overrides to use ACLK where I tell it to use SMCLK in the initRTC() function

Hi Manu, there is really something strange. it looks like that P3.2 does not work The expected result would be Without the jumper dir=0x04, out=0x04 -> p3in = 0x04 dir=0x08, out=0x08 -> p3in = 0x08 Without the jumper dir=0x04, out=0x04 -> p3in = 0x0C dir=0x08, out=0x08 -> p3in = 0x0C Can you check this on another board?

Forum Post: RE: CCS/MSP430FR5739: After CCS update long running project cannot load with MSP-FET emulator "Error connecting to the target. Unknown device."
Hi Samuel, happy to hear the migration to CCS9 solved the problem. The CCS environment is a complex system consisting of many components, not really visible to you as a user. We try to maintain the compatibility when updating those components, but especially with older versions it gets more and more difficult. If everything works as intended, there should be nothing to change. The update procedure in CCS is from top level point of view as follows: If you have a CCSx version installed, you get all the updates for this CCSx, like in you case with CCS6.x. You got all the updates from CCS6.0 to whatever the highest version of CCS6.x was. But e.g. the migration from CCS6.x to CCS7.x does not happen by updates. You need to install another instance of CCS. On your side with the CCS6.x updates some of the components related to your original project got into a version mismatch probably. That's the most probable root cause for such issues. To explore a bit more in detail on the "image" topic, no matter how you create your code, whether it is assembler, C-Code, C++ etc. in the end the IDE creates the necessary machine code, which is programmed into the device, as this is the only code the microcontroller understands. Usually, when working with an IDE like the CCS, you do not look into this code and do not generate the so called image file, which is the reflection of this machine code. But if you want you can see it, e.g. by opening the pull-down menu "View>>Disassembly". There you can see, e.g. in case you have written the code in C, the C instructions, the translation to assembler, and the final machine code. The image file is sort of just the machine code, including some other instructions, or markers, dependent on the format, where accross the industry some different standards have been established, like Intel HEX, TI .txt and others. This is about how the machine code information is stored in the respective file, including information about the code placement in the program memory of the MCU. This image file is not generated by default, as not needed by the IDE, which uses it's own format. To enable the creation of such an image file, one has to go to the project properties >> MSP430 HEX Utility >> enable MSP430 Hex Utility >> Output Format Options >> click on the Output Format selection on the right >> select desired format e.g. TI-TXT. The advantage of such a file is, it does not change anymore with IDE or Compiler updates. The disadvantage is, in case you want to change some values, like in your case IDs, you would need to know the location of the IDs and change the file manually, which is pretty risky, as if you make a mistake, there is no compile check or anything that would tell you. The other option would be using this image file in combination with a professional production programmer, like our MSP-GANG , which supports features like serialization, means updating some IDs with each and every programming cycle to support recognition of the devices by a unique ID. If you want to learn more about this, please visit the landing page of our Gang programmer www.ti.com/.../msp-gang and the related User's Guide. Best regards Peter

Forum Post: TMS320F28069M: How to Clear capture event status Flag in MATLAB.
Part Number: TMS320F28069M I am working on motor control and i am able to read the speed from the Hall sensor using the Capture module in Matlab-Simulink, But when I give stop command to the motor, the last capture value is passed on for my speed calculation. and hence giving a false reading. For this, I am thinking to use either capture interrupt flag or capture event status register, But I adon't know how to make this value zero so that I can differentiate between fresh capture status. Hope Somebody can help.

Part Number: MSP430F5419A Tool/software: Code Composer Studio Hi, I have a board which has an external 16Mhz crystal on XT1.

Forum Post: CCS/LAUNCHXL-F28379D: problem running the eQEP C2000ware example
Part Number: LAUNCHXL-F28379D Tool/software: Code Composer Studio I tried the "eqep_pos_speed" example on C2000ware few days ago and everything was working fine. I wanted to try it again and suddenly the variable "SpeedRpm_fr" is not giving any value anymore. it's always 0. On the other hand the other value "SpeedRpm_pr" for low speed measurement is working perfectly. I starting to think that the problem is from my card (maybe heating ?). I just unpluged my card for like 30 minutes and plug it again and it's given me the value I want. And after little bit it gives me 0 again. I hope someone can help me identifying the source of problem.

Part Number: TMS320F28375D I am not able to program the referenced device when using the XDS200 emulator but can when using the XDS510. The problem seems to be the XDS200 cannot pull the TRST line low enough to reset the device prior to programming. A check of the waveform on TRST shows the XDS200 only pulls the signal to ~1.7Vdc where the XDS510 pulls the signal to ~1.3Vdc. My design has a CPLD on the TRST line as well that provides a +3.3V logic level.
