Part Number:MSP432E401Y
Does the MSP432E401Y chip on the MSP432E401Y Launchpad have an RTC?
This document, mentions some RTC-related pins: http://www.ti.com/lit/ds/symlink/msp432e401y.pdf
However, I'm not able to include the RTC header files from driverlib and I see no mention of an RTC on this page: http://www.ti.com/product/MSP432E401Y?jktype=soc

Part Number:LAUNCHXL-CC26X2R1
Hi All,
My client asked me to implement an API as when the peripheral receives a connection request from central, only if user presses a Key (left key), allows the connection is established. Is this possible? Can I postpone establishing a connection and add a condition like this? Is there any event code can inform me a request is received before accepting it?

Hi Dean, Noel
About two weeks ago I got from Dean some pictures from the simulation he did for Amimon. (attached the email).
Yesterday I got from Noel the simulation file (attached also)
I attached also a short presentation (which I already sent you by email 2 weeks ago) with our requirements.
Below are some question regarding the results (I use PLLat version 1.5.4). If you see that a better option to have a short webex discussion instead- please let me know
1.When I cover (with Noel simulation file) the frequency range which I need (10.82-12.62 GHz) I got design warning "VCO/MinHighCap Restricted BW". How should I overcome it? is this significant issue?
2. You choose to use is a 2nd order Loop filter . Why? can you explain shortly (if possible) the trade off to 3rd order
3. The cap C1 you choose is 2.7nF (below 3.3nF). The value gives a yellow mark. How should I consider this regarding you recommendation to use value > 3.3nF.
4. At your simulation file: when I choose "Spurs" tab and then go back to "Filter Designer" tab and then go back again to "FilterDesigner" tab- I see spurs marks on the graph which have not appear before. Is it a simulation bug ? (I add a picture with a red mark).
5. I added a simulation with the suffix"Refael". At this simulation I change C1 to be 3.3nF and C2=22nF.
Basically I do not see significant differences with your simulation but the value of C1 is 3.3nF here. What do you think?- should I use these value instead? (I can handle the loop filter small degradation at 10.82GHz to Loop=189KHz.)
Part Number:TDA2PSX-ACD
We use the above mentioned part for our system. We had performed a FMEDA for our product and need to look more closely to the TDA2PSX-ACD.
- Could you provide detail data for failure rate calculation?
- Do you have an allocation of areas used for different sub-modules?
- When switching to the device TDA2PHG-ACD is there anything we have to take into account from functional safety point of view?
Thank you for your support.
Best regards

Part Number:LAUNCHXL-CC26X2R1

Hi,
I am interfacing MAX30102 to the launchxl-2652 , I selected I2C example of the board and interfaced the module to the controller in both interrupt mode and polling mode using the interrupt pin of the module and it worked properly. But when I integrated the code to simple ble peripheral project I started getting too many false interrupts on the interrupt pin of the MAX30102 module. Because of this the sensor I could get the proper values of module. I do not know why it's behaving like, if anybody has any idea when I need to look to solve this issue please let me know.
I used DIO13 as interrupt pin for the module so I commented the settings for the pin in array
const PIN_Config BoardGpioInitTable[] = {
CC26X2R1_LAUNCHXL_PIN_RLED | PIN_GPIO_OUTPUT_EN | PIN_GPIO_LOW | PIN_PUSHPULL | PIN_DRVSTR_MAX, /* LED initially off */
CC26X2R1_LAUNCHXL_PIN_GLED | PIN_GPIO_OUTPUT_EN | PIN_GPIO_LOW | PIN_PUSHPULL | PIN_DRVSTR_MAX, /* LED initially off */
//CC26X2R1_LAUNCHXL_PIN_BTN1 | PIN_INPUT_EN | PIN_PULLUP | PIN_IRQ_BOTHEDGES | PIN_HYSTERESIS, /* Button is active low */
CC26X2R1_LAUNCHXL_PIN_BTN2 | PIN_INPUT_EN | PIN_PULLUP | PIN_IRQ_BOTHEDGES | PIN_HYSTERESIS, /* Button is active low */
CC26X2R1_LAUNCHXL_SPI_FLASH_CS | PIN_GPIO_OUTPUT_EN | PIN_GPIO_HIGH | PIN_PUSHPULL | PIN_DRVSTR_MIN, /* External flash chip select */
CC26X2R1_LAUNCHXL_UART0_RX | PIN_INPUT_EN | PIN_PULLDOWN, /* UART RX via debugger back channel */
CC26X2R1_LAUNCHXL_UART0_TX | PIN_GPIO_OUTPUT_EN | PIN_GPIO_LOW | PIN_PUSHPULL, /* UART TX via debugger back channel */
CC26X2R1_LAUNCHXL_SPI0_MOSI | PIN_INPUT_EN | PIN_PULLDOWN, /* SPI master out - slave in */
CC26X2R1_LAUNCHXL_SPI0_MISO | PIN_INPUT_EN | PIN_PULLDOWN, /* SPI master in - slave out */
CC26X2R1_LAUNCHXL_SPI0_CLK | PIN_INPUT_EN | PIN_PULLDOWN, /* SPI clock */
CC26X2R1_LAUNCHXL_PIN_RLED | PIN_GPIO_OUTPUT_EN | PIN_GPIO_LOW | PIN_PUSHPULL | PIN_DRVSTR_MAX,
PIN_TERMINATE
};
And also I commented two button menu settings that I found in the function SimplePeripheral_init()
// Initialize GATT Client GATT_InitClient(); // Init key debouncer // Board_initKeys(SimplePeripheral_keyChangeHandler); // Initialize Connection List SimplePeripheral_clearConnListEntry(LINKDB_CONNHANDLE_ALL); //Initialize GAP layer for Peripheral role and register to receive GAP events GAP_DeviceInit(GAP_PROFILE_PERIPHERAL, selfEntity, addrMode, NULL); // Initialize array to store connection handle and RSSI values SimplePeripheral_initPHYRSSIArray(); // The type of display is configured based on the BOARD_DISPLAY_USE... // preprocessor definitions dispHandle = Display_open(Display_Type_ANY, NULL); // Initialize Two-Button Menu module /* TBM_SET_TITLE(&spMenuMain, "Simple Peripheral"); tbm_setItemStatus(&spMenuMain, TBM_ITEM_NONE, TBM_ITEM_ALL); tbm_initTwoBtnMenu(dispHandle, &spMenuMain, 5, SimplePeripheral_menuSwitchCb); Display_printf(dispHandle, SP_ROW_SEPARATOR_1, 0, "====================");*/
Signals I captured using the logic analyser for interrupt pin of MAX30102 I attached in the post and I'm currently using CCS 8.3.0 ,BLE SDK version 3.10.0.53 and zigbee sdk version 2.20.0.6(Please visit the site to view this file)

Part Number:ISO7221C
Good morning, everyone.
In my application I have to isolate a canbus line that works at 500kbps.
Which of the two isolators do you think is the most suitable?
Comparing the two isolators from the DATASHEET I see that the ISO7721 model has more performance than the ISO7221c but the price of the ISO7721 is lower than the ISO7221.

Hi all
We use the demo board of IWR6843, and compare with our board.
The distance of ours is shorter than demo board
But we test the EIRP of our board and demo board, we do not find any difference.
So do the chip have any hardware configuration will affect the distance.
Thanks .
Part Number:TPS65988DJ
Hi team,
My customer would like to consult with you. Is the OVP trip point alway setting at 24V and it couldn't be modify by different PDO?
Can we modify the slew rate by external hardware ? Does the slew rate definition mean the every PDO changing speed or only mean the soft start speed?
And, if the customer use the external power patch for source, does our TPS65988 still have OVP protection function with VBUS pin connecting to one side of power switch?

Hi,
During debugging, debugger is stuck at line;
LOG_INFO("Starting " CONTIKI_VERSION_STRING "\n");I am reading this problem in many threads but didn't find any solution.
Did anybody solve this problem? If yes, how?
Part Number:LAUNCHXL-CC1350
Hello,
I am sending data via radio with a CC1350 microcontroller. I measured the time it takes to transmit a 128byte message (the blocking API - the time measured was the time taken by the EasyLink_transmit method) with the EasyLink library and the value measured was ~ 15ms. Is this normal. How can I shorten this time ?
Thank you very much!

Part Number:LM25118
Dear all:
The output of LM25118 is 5V, and the input is also about 5V (PC supplies 5V). The efficiency, I measurement the input voltage, input current, output voltage and output current are measured to calculate efficiency the test results are as follows:
(5.035V*0.496A)/(4.985V*0.673A)=74.4%
is only about 70%.But I think the Data sheet is pretty efficient.
Please help to analyze the possible reasons for the inefficiency.How to improve output efficiency?
Part Number:TMS320F28035
Does the PD pin of JTAG Header have to connect to the VDDIO? Customer wants to power PD pin with 5V come from USB.
I checked the below statement for PD pin. It seems that connecting to VDDIO can indicate the emulator whether C2000 is powered up or not, right?
Presence detect. This signal indicates that the emulation cable is connected and that the target is powered up. PD should be tied to V CC in the target system.

Hi,
We are in the process of removing the unwanted usecases and alogorithms in the apps project of vision sdk, below we have some questions regarding build system.
1) Is this the right way to remove the unwanted usecases and algorithms from apps folder?
2) We removed some of the algorithms in alg_plugins, but we hope these mentioned alogorithms are required for building the sdk E.g(edgedetection,streo_app,denseopticalflow,surrondview..etc). We looked into the MAKEFILE.MK and the below libraries are included by default in sdk, eventhough ALG_var_name is not set in the usescases. Could we know what is the reason?
