Hi Sir,
We are trying to build and execute our unit test cases using C7X host emulation guideline provided in below document
Refer to: https://www.ti.com/lit/ug/spruig6i/spruig6i.pdf
We are using mingw64 compiler as mentioned in above guideline. But when we try to build it is showing many type related errors as below.
Looks like the types in mingw compiler is conflicting with the types in c7x types. Please help us to resolve this

Dear SIr/Madam,
Can you help to share the MSP430FR2100 reference source code for TIDA-050007
Best regards,

Hello,
I have received the ULC1001-DRV290XEVM along with the sample lens. In addition, I have reviewed the recommended TI lens design documents (SLAA975A and SLAA962). Both of these documents clearly illustrate the design requirements for a round lens. However, for our design, a rectangular lens would be more space efficient. I don't know if it would be possible to set up resonant cleaning waves on a non-circular lens without having it fracture.
Does TI have any experience or design resources to help with design of ultrasonic cleaning of non-circular lenses that work with your ULC1001 ICs ? Are there specific warnings against trying a non-circular lens? Any feedback would be appreciated.
Best regards
Rick
Hello,
i recently installed the latest version of Pspice for Ti, and i am trying to do some basic bode ploting for gain & phase using custom formula
I want to add these 2 expresions in my plot
DB( V(out) / V(in) ) and P(V(out)/ V(in) )
I can add them manualy over the existing "Bode plot - dual Y axis" template.
But how to save these expresions so each time i run the simulation, i dont need to enter them manually?
I google'd a bit and found some information here https://www.pspice.com/sites/default/files/CreatingCustomPlotWindowWithPSpice.pdf
But i dont see such settings in this TI's version of Pspice.
How shall i proceed?
Hello, Texas team.
I have built up a PMP22075 using the gerbers etc supplied.
The design is described as having an input voltage range of 9V to 60V.
My Problem - But when I reduce the input voltage, the output starts to drop from nominally 12V once the input voltage is less than approximately 10.75V.
Investigation so far - Duty Cycle - As expected, I can see the duty cycle of OUT_A of the LM5026 increase as the input voltage reduces.
BUT the duty cycle hits a limit of about 73% - when the input voltage equals 10.75V approx.
My question: Please advise how I can achieve a full 12V output when the input voltage is at the low end of the range (from 9V to 10.5V say)?
(Our application requires a minimum input voltage of 10.5V).
Thanks in advance.
In the reference design guide "https://www.ti.com/lit/ug/tidudr0/tidudr0.pdf?ts=1683780379508&ref_url=https%253A%252F%252Fwww.google.com%252F", there is one feature "“Supports VESA DisplayPort Alt Mode to USB-C UFP and DFP configuration ”.
My questions are:
1. What's the difference for UFP and DFP configuration?
2. That means, can this design also be used as " VESA DisplayPort Alt Mode to USB-C "?
Best Regards,
Haidong
Hi team,
Could you pls help to address that the SRF function in the Demo code adds a limititation of 200 after PI output, but DDSRF does not add a limititaion; if there is any special consideration?
Thanks

Hi,
I was simulated LM5122 circuit in PSpice for TI earlier.I plan to use the LM5122 circuit to control the boost. In the datasheet of that circuit, there is a proposal where it is controlled using a voltage divider from the output that is fed to the FB pin.
However, I need to operate the steering by electricity. I need to filter the current signal from the saw-shaped shunt (maximum 30 mV voltage) and amplify it 10 times (this would be done by the first part of the circuit),
and then give the second part of the circuit, on which the value is set, the current value (shown also by the voltage, which will after amplification the maximum will be 300 mV),
regulate according to the mean value of the current and that the voltage at the output of 1.2 V is fed to the FB pin of the circuit LM5122 (internal error amplifier) which will start the circuit to do the regulation.
In short, can you offer a circuit that will do regulation by the mean value of the choke current? I need to modify the LM5122 circuit, by removing the voltage control offered in your datasheet,
and adding a current control that represents a feedback loop that leads from the shunt to the FB pin of the circuit.
Best regards,

Hi Team,
Our customer has a couple of questions regarding TIDA-010042:
1. Why are R45, R45, R55, R56, D8, D9, D10, D11, D12 and D13 not supposed to be populated?
What are the use of R45, R46, R55, R56, D8, D9, D10, D11, D12 and D13?
I read the technical data but it did not explain why those components are DNP.
2. Do you also have CSD19531Q5A and CSD18540B for TO-220 package Version? According to the schematic, I can get 40A by swapping the MOSFET to TO-220 version.
If you don't have them, may you recommend which MOSFETS I can use in the design that have the same characteristics as the CSD18540B and CSD19531Q5A.
3. Do you have a video related to TIDA-010042 programming? I have built 3 of them and I want to test for 12VDC, 24VDC and 48VDC for my project. However, I'm experiencing difficulty on how to get the system up and running while connected to the battery and Solar panels (that delivers 30VDC). I'd appreciate if there is a video showing how to connect the solar, battery and load to get the feeling on how it works before programming the MCU. We would appreciate if you could help us on where and why to connect the pins on the jumper connectors. They are very confusing.
Thanks in advance!
Kind Regards,
Jejomar
Hi Sir
For right now, I am developing bidirectional dc-dc using F280049.
How do I get source code for TIDA-00951? I need the source code to enable HW so urgently.
Thanks a lot.

Hi Experts,
Good day

Hello experts,
I would ask you for help to find what can be wrong that I cannot Export a coil to any of cad formats.
After I select desired cad format and click Export button, the message "Processing CAD Export" appears, and after a minute it writes a message:
Please check your connection or retry your inputs to proceed."
I tried to export different coil designs, different computers and different browsers, so it seems should be something wrong on server side.
By the way, this is my main coil design I need for current project.
Many thanks for your support,
Edvard
I am a newbie in Pspice software. This is my very first trial to use it and I am stuck.
When I try to use the 'Open model test circuit' for UCC28881 it downloads some projects. When I try to run the simulation it shows an error in the subject. This is a log:

Dear Expert
We have some totem pole PFC design issue need support .
The Q3 ,Q4 of the totem pole is easy to damage during the soft start process. Can the Q3 ,Q4 not be turned on during the PFC start process, and the driver signal be turned on after the PFC is start opration?
Dear all,
I am looking for IBIS or SPICE or S-Param models of the following PN:
- REG113NA3.3
- REF3130AIDBZ
- TPS3828-33QDBVRQ1
- TS3A5223RSWR
Unfortunately I can't found them in the TI website.
Do you have any suggestions to find such models in other way?

MC
How to manage two ALERT pins of two bq76930 simultaneously by a host MCU?

Hello E2E Experts,
Good day.
The following code builds with no errors on C99 and C++03 with GCC but I get an error with CCS:
#include <stdint.h>typedefenum DRV8323_RW { DRV8323_WRITE =0, DRV8323_READ =1} DRV8323_RW;typedefunion DRV8323_DATA_WORD {struct{ uint16_t data :11; uint16_t address :5; DRV8323_RW rw :1;}; uint16_t value;} DRV8323_DATA_WORD;intmain(){ uint16_t foo =((DRV8323_DATA_WORD){.data =23,.address =12,.rw = DRV8323_WRITE }).value;}
error #2718: a designator for an anonymous union member can only appear within braces corresponding to that anonymous union
Is CCS not compatible with C99 and C++03?

Hello,
Could you please send me the PSPICE model for LMG3526R030. Also the data sheet for the same does not mention about the Eon and Eoff (Energy) for the switch. Could you also provide me that information.
Thanks,
Neha Agarwal.
I just downloaded the simulation model from following link.
I keep getting error message "ERROR(ORCAP-15053): Can not initialize PSpice UI"
I installed Pspice for TI version 17.4-2023.

i don't see`apical_process_cli' in any library. I could not find glbce_model.c either.
