Part Number: OMAP-L138 Tool/software: Code Composer Studio hello, I referred the code for configuring GPIO as an Input using Interrupt. https://e2e.ti.com/support/processors/f/791/t/384704 I am using OMAP-L138 DSP+ARM9 Development Kit, with Starterware, I can read status of SD card(pin 65(GP4[0]) as input.), User button 1 (pin 38GP2(5)as input.) User button 2 (pin 37GP2(4)as input.) but unable to read pin61GP3[12] PIN62GP3[13] pin44GP2[11] AND few more. Could plz help to resolve?

I want to pass a summed signal of two sine waves and eliminate one of it using fir filter. I produced the sample values of the summed signal in matlab.

I want to change the path to generate the output directory files. it is like in IAR (options->General Options->Output) similarly needed in CCS. Is there any options like that in CCS? Thank you!

Forum Post: RE: CCS/MSP430FR5969: Why was MSP430Ware ‘products’ support in CCS dropped?
Thank you. I had used the standalone installer, and I wanted to post an update, but my post was in moderation queue, and couldn't even see it in my activity on my profile page. After installing MSPWare 3_30_00_18 it showed up in Products. So, it seems that it’s not a CSS version, but an MSPWare issue. In eclipse/CCS on the update URL ( http://software-dl.ti.com/msp430/msp430_public_sw/mcu/msp430/MSP430ware/update/latest/ ) 3.50.0.04 is the latest version, so I guessed that that might be the last version with CCS product support. After the site URL was added I was able to install this version as well from the repository inside CSS (Help - Install New Software...). Though only the MSP430Ware showed up as new version, the driverlib did not (MSP430Ware_3_50_00_04 folder has MSP430 DriverLib 2.80.00.01) But for me this seems to be more like a bug than dropped support to reduce download sizes, because the driver lib plugins are still there in all versions: MSP430Ware_3_50_00_04\driverlib\eclipse\plugins\com.ti.mcu.msp430.driverlib.product.ui_2.80.0.01 MSP430Ware_3_50_00_04\driverlib\eclipse\plugins\com.ti.mcu.msp430.driverlib.product_2.80.0.01 MSP430Ware_3_50_00_04\driverlib\eclipse\features\com.ti.mcu.msp430.driverlib.product.ui_2.80.0.01 MSP430Ware_3_50_00_04\driverlib\eclipse\features\com.ti.mcu.msp430.driverlib.product_2.80.0.01 msp430ware_3_80_03_07\driverlib\eclipse\plugins\com.ti.mcu.msp430.driverlib.product.ui_2.91.05.02 msp430ware_3_80_03_07\driverlib\eclipse\plugins\com.ti.mcu.msp430.driverlib.product.ui_2.91.5.02 msp430ware_3_80_03_07\driverlib\eclipse\plugins\com.ti.mcu.msp430.driverlib.product_2.91.5.02 msp430ware_3_80_03_07\driverlib\eclipse\features\com.ti.mcu.msp430.driverlib.product.ui_2.91.5.02 msp430ware_3_80_03_07\driverlib\eclipse\features\com.ti.mcu.msp430.driverlib.product_2.91.5.02 msp430ware_3_80_07_00\driverlib\eclipse\plugins\com.ti.mcu.msp430.driverlib.product.ui_2.91.11.01 msp430ware_3_80_07_00\driverlib\eclipse\plugins\com.ti.mcu.msp430.driverlib.product_2.91.11.01 msp430ware_3_80_07_00\driverlib\eclipse\features\com.ti.mcu.msp430.driverlib.product.ui_2.91.11.01 msp430ware_3_80_07_00\driverlib\eclipse\features\com.ti.mcu.msp430.driverlib.product_2.91.11.01 What is missing is the eclipse folder (MSP430Ware_3_80_07_00\eclipse) which is 8725 bytes uncompressed, the products folder (MSP430Ware_3_80_07_00\products) with its huge 153 bytes. So, to my understanding, removing these features saved less than 9 kB total… but still kept megabytes of unused plugins… not just unused, but updated new versions of plugins (meaning engineering effort, time)… Nice! ...but maybe I’m just missing something… (The MSP430Ware_3_50_00_04 actually has the eclipse folder only the 153 byte products\manifest.xml file is missing.) After investigating further, I installed the standalone MSP430Ware_3_80_07_00_setup.exe, and it does still support these plugins! And the standalone installed version is around 500 MB smaller than the one Resource explorer installed. (The Resource explorer version has files like msp430ware_3_80_07_00\apps\MSP-EXP432P401R_Software_Examples_linux.tar.gz Maybe it couldn’t detect that I was running windows, or just thought that I still needed the Mac and Linux examples... But it sure saved at least 9 kB by removing these features and not having the manifests for the plugins… and wasted hours of my time.) I guess my advice is that (if you want this feature) don’t use resource explorer to install MSP430Ware, instead use the standalone installer! Or just save this to MSP430Ware_*\products\manifest.xml Now I have all my driver lib versions:

Forum Post: RE: CCS/LAUNCHXL-F28377S: Application code
Jingtai, In general you add .c files to your project and then for .h files you setup the search path in your project options so that the compiler can find the header files. The location in the project options to specify the search path is here (if you are using a C2000 device it will say C2000 Compiler instead of MSP430 Compiler): Regards, John

Forum Post: RE: CCS/TMS320F28335: ADC SOC Example not reading full range of Values
Hi Kyle, If you cannot connect ADCLO to one of the input channels then you can just connect 0V instead. Once you have made this connection then you can follow the flow chart (Figure 1-12) essentially taking multiple ADC conversions, averaging them out, subtracting the average from the value in the OFFTRIM register, and then writing that result back to the OFFTRIM register. What is meant by "a centered zero code" is that after the offset error correction process there should be a half bell curve distribution (Figure 1-13). When sampling a 0V reference, the largest majority of output code readings should be zero, and then tempering off as the output code value increases until reaching 4095. Best Regards, Marlyn

Forum Post: RE: CCS: Using System analyzer (UIA target) Speed measurement question.
JunYoung, I am not familiar with the lab manual you are referring to. Here is some general information you will need to figure out the time: A cycle generally refers to a clock cycle (a single tick of the internal clock.) Cycles per second are also called Hertz, or Hz, thus a 2 GHz CPU (two gigahertz) goes through 2,000,000,000 cycles every second. Thus if you know the frequency that your CPU core is running at you can calculate the time. Regards, John

Forum Post: RE: CCS: CCS ISSUE
Hello Jinwook, The basic methodology is laid out in the app note. You will need to make a custom calculation for your sensor though. As far as the NFC part goes, I have provided all I can on that front. If you have further MSP430 specific questions, then please make a post to the MSP430 forums on the topic about how to use the device to do calculations. I am not an expert to support the MSP430 MCU so the information in the app note is the most I can offer on that front.
