Part Number: LM3150
Before I spend a lot of time finding this out the hard way, does the TINA-TI model for the LM3150 support the inverting buck-boost topology?
I've run into several models lately that have internal nodes tied to ground and don't work for this topology.
Thanks, Best, Steve
Part Number: BQ51013B
Hello,
I'm building a device that incorporates a bq51013B based receiver. What is the best way to quickly verify that the receive circuit on the PCBA is working? This is before the coil is attached, just the populated PCBA. Can I take a qi transmitter dev board, remove the coil, and hard wire it to the receiver through voltage limiting resistors to simulate the two coils being near each other? I don't want to have a transmit coil taped to a receive coil because there are a lot of devices being tested simultaneously and that would just generate a lot of interference.
Thanks,
Derek
Part Number: LAUNCHXL-CC1352P
Tool/software: Code Composer Studio
Hello,
I wanted to interface the ENC28J60 with the CC1352P1. I'm able to talk to the device over SPI and have configured it to be able to transmit dummy ethernet packets to my computer which I can sniff out using Wireshark. I wanted to find out if there is any TCP/IP stack or UDP stack which I can run on the CC1352P1 and thereby have an IP address to receive messages on.
Warm regards,
Samyukta
Part Number: INA3221
Hello team,
Can INA3221 be directly tied to a 1.8V I2C bus if the supply voltage for INA3221 is 3.3V? I would think not and a level shifter like TXS0102 or PCA9306 is needed, but wanted to make sure for customer design.
Thanks!
Part Number: SN74AVC4T774
Hello,
It looks like there are a couple parts that can be used for SPI voltage translation. LSF0204, TXB0204, SN74AVC4T774, etc. I want to understand what would be the best way to implement my particular use case. Here are my careabouts:
I considered using the LSF0204 in single supply mode but then would need pull-up resistors on my signals.
I considered using the SN74AVC4T774 but do not believe it will give me the flexibility of switching between 1.8 and 3.3.
Please advice.
Thanks,
Vibhu
Part Number: ADS131E08S
Good morning Team,
I want to know about what is the six sigma for ADS131E08S? Is it 3 -4 OR 5-6?
Also what is six sigma for typical electronic manufacturing process.

Part Number: BQ25601
Hi all, I have a design where the external power (Qi receiver) may be removed at any time, and additionally due to the occasional relatively high power consumption of the device (custom smartspeaker with significant LED lighting) all the power from the Qi receiver and more is consumed, i.e. current is sourced from the battery for these peaks.
The firmware currently asserts CE/ at startup and holds it low forever.
Question: is the safey timer reset in the conditions of external power removed / no current into battery even if I don't toggle CE/ to specifically initiate a new charging cycle?
The BQ25601 correctly reports not charging when the external power is removed. I assume this means a new cycle begins and the charge timer is reset when it is restored. But I have no way to know. (I think...?)
Thank you!

Part Number: CC2652R
Hello,
We have a sensor controller program that samples multiple capacitive sensors on a CC2652. It works very well running stand-alone in Sensor Controller Studio with very little noise in the sampling.
But when we integrate it with the main app (based heavily on Project Zero / TI-RTOS), the noise increases by several orders of magnitude. Typical capacitive counts are in the ~5000 range with noise of around +/- 50 counts (~1%). But when integrating the exact same code into my Project Zero based App, the general readings are the same, but the noise jumps to +/- (mostly plus) 1000-2000 counts or more. (~20-50%)
This is a killer for our entire application... We are specifically looking for very sudden large spikes due to physical impact -- so we can't filter out the spikes because that is exactly what we're looking for.
Is the constant current source vulnerable to interference from the main ARM and BLE processor current draws? (It doesn't seem to matter if I'm running on XDS-110 power or on battery.) Are there known issues with this? Or is there some other effect that we are not accounting for?
Do we need to shut down the main ARM to get clean samples? (May be very hard to do) And what about the BLE core and transceiver? We're collecting and transmitting data continuously, so we can't just shut down the radio very easily either.) Not sure if we can set a semaphore or mutex that would keep the sensor controller from running at the same time as the BLE is broadcasting.
Any and all help appreciated.
Thanks in advance,

I am using old GUI (from 2013) to download ".x0" file into UCD3138 devices.
The current GUI will say: "The GUI was unable to find the device id in the firmware file. Error message: A valid device id would be for example: UCD3000ISO1,UCD3100ISO1,UCD310064V1,UCD310128V1,UCD310A64V1,UCD3138A,UCD3138064A,UCD3138128A,UCD3138A64A. Must specify valid information for parsing in the string."
What steps are needed to put this "device id" into ".x0" file.
I need to be able to duplicate this on the command line, I need to know how this feature works. So a pure GUI based approach is not sufficient.
I have tried to find the answer in the compiler PDF documents, inside the "armhex" and the older "hex470" sections, but could not find the answer.

What is the range of values to which Tx power can be set, and how does that change the power consumption? I'm looking for power consumption as a function of the Tx power.
Part Number: TMS320F28335
I'm planning a design for a custom secondary bootloader for the 28335 and I would appreciate a sanity check. Here are my requirements:
The concept is as follows:
I'd like for the firmware and the secondary bootloader to be in the same CCS project as the application. The alternative would be to maintain a separate bootloader project and load it into RAM via boot ROM, but I'd like to avoid having two separate projects if possible. My main question then is, will sending what is essentially a "jump to secondary bootloader" command to the boot ROM work? That is, if I place my "boot_main" function at a specific address via the linker, then send that address as the entry point to the boot ROM, are there other considerations I should know about? I know that typically the boot ROM jumps to code_start which then calls _c_int00 for C initialization (and it calls main), so is there a way to achieve what I've described?

the code block not to be optimized:

GPIO_setOutputEnableDio(IOID_8, GPIO_OUTPUT_DISABLE);//HWREGBITW( GPIO_BASE + GPIO_O_DOE31_0, IOID_8 ) = GPIO_OUTPUT_DISABLE; //

//GPIO_clearDio(IOID_8); //gpioClearOutput(Board_DIO8);
IOCIOInputSet(IOID_8, IOC_INPUT_DISABLE); //gpioDisableInputBuf(Board_DIO8);
if the project optimization is set to none, the code work as expected. with any optimization , the code does not work as expected. it seems the 1st line of the first 2 lines was optimized off, but this 2 lines are critical for the code to work，as the 1st line is to charge a capacitor and the 2nd line is to discharge the capacitor, so that a great change of a serial resistor could be detected.
and optimization for code size is prefered, so only need to prevent the compiler from optimizing several lines of code.

__STATIC_INLINE void
GPIO_setOutputEnableDio( uint32_t dioNumber, uint32_t outputEnableValue )

I wish to construct a table of assembly-statement strings of the form
"bis.b #1, P1OUT"
that can be used in an asm() statement like
asm(" *table[i]");
but trying something so simple as
#include <msp430.h>
void setbit0(void) {
asm(" bis.b #1,&P1OUT");
}
fails. It produces the error:

How can I persuade the compiler/assembler to let me use P1OUT in an asm() statement?
(The compiler invocation does include the processor define

needed by msp430.h.)

Hello, I am in the process of debugging. Because uartpolling will affect the normal operation of the program, I changed it to uartpolling. At this time, the radar board can work normally.However, when I was debugging, I found that the watchdog and poweroff commands would not work (but when I switched back to uartpolling, the watchdog and poweroff worked fine, but the radar front would crash and the board would stop running after a few seconds).What is the problem and how should I correct it?Hope to get your reply。

Part Number: TS3DS10224
Hi,
I have get some confuse about TS3DS10224.
1. Does the device can support UART/USB switch?
2. If INA+/- and INB+/- are 1.8V level, OUTA+/- and OUTB+/- output level are still 1.8V?
3. If TS3DS10224 can’t use 1.8V level as input signal, and we need to add level shift before input into INA & INB?

Hello everybody.
I'm testing IPC sample(ipc_ex2_msgqueue_c28x1) in C2000Ware DriverLib.
I checked to send IPC message from CPU1 to CM and trigger interrupt to CM interrupt handler.
But when sending IPC message from CM to CPU1, CPU1 is not triggered inturrupt to CPU1 interrupt handler.
Using IPC API "IPC_readMessageFromQueue" CPU1 is successfully read data from message ram(CM to CPU1)
I already check CMTOCPU1IPCSTS registor in CPU1. the registor is normally set IPC flag. but not triggered interrupt.
how can I programming that CPU 1 is triggered interrupt routine by IPC message CM to CPU1?
