Part Number:DP83867E
Hi Team,
The customer uses the DP83867E to connect to the CPU via SGMII. It is always unrecognizable after connecting the Internet cable.
The PHY address can be recognized by MDIO, and the PHY register can also be read and written. Connect the development board directly to the computer through the network cable, but always show that the network cable is not connected. Customer Reference DP83867E SGMII EVM Circuit.
Thanks.
Part Number:CC2564MODA
We are implementing a HID host service with bluetopia 4.0.2.2.
We want to change the baudrate from 115200 to e.g.230.400 but without success.
In the pdf documents are stated that the baudrate can be changed after InitializeApplication. We do this with a call to "HCITR_COMReconfigure". In the function we change the baudrate of our usart to the new value but after this a call to GAP_Perform_Inquiry comes back with error -14 general driver error.
At which moment can we switch the baudrate and must we do something more to change it?
Part Number:TUSB322I
A customer would like to configure TUSB322I as UFP-only mode with UFP accessory support disabled. But it shows CC toggles.
EN_N low, I2C mode, Vdd active.
Max time from EN_N low and Vdd active to I2C access available is 100ms.
So the external MCU wait for 100ms since TUSB322I is powered on.
Then it initializes the register via I2C as follows.
[1] ADDRESS 0x0A = 0x01 ( Disable termination )
[2] ADDRESS 0x0A = 0x11 ( UFP mode )
[3] ADDRESS 0x09 = 0x21 ( Disable UFP accessory support )
[4] ADDRESS 0x0A = 0x10 ( Enable termination )
I think that the procedure is correct. My only concern is the duration between register accesses.
Do you have recommended duration between register accesses?

Part Number:DRV8833
Hi Team,
Regardless of the input level of BIN2, the output pwm direction will not change. Is customer's design problem or the chip is broken?
From below picture, it should be able to change the direction of the output current by changing BIN2.
Thanks.
Part Number:TLC5958
Dear Sir,
We have designed a 16X144 RGB LED matrix and used 9 TLC5958 LED dirves ICs for circuit design.
The following documents were referenced:
1. TLC5958 datasheet
2. tidr683.pdf-tidr688.pdf
3. slva645_5_.pdf
This LED Matrix will be used to Display English text on it . I have written the source code for it (By taking Reference of TLC59581 sample code ) but the intensity of the LED's is too low . I have set the BC bits value in Function Control(FC) Register FC1 to (0b111) maximum . but still the brightness of the LED's is too Low . Please help me to find the solution of this problem .
Thanks & Regards,
Jaswant

Tool/software: Code Composer Studio
Hi team,
I am confused with the difference between the CLA of 28379D and 28035.
I found that the control effect in 28035 was not as good as 28379 when they use the same control code. The positionless estimation results of the motor were quite different, and finally affect the closed-loop control. Both 28379 and 28035 used 12-bit ADC.
Besides,does the CLA of 28379 and 28035 have a big difference in computing power?

We are working with bluetopia v4.0.2.2. We want to pair a HIDController/keybaord with the BT stack.
What we do:
1. changing the stack to HIDHostMode
2. call Inquiry
3. pairing the listed device
The result is:
HID Device>
atAuthenticationStatus: 4 Board: 0x5CBA370E174E
We get not always the same result. Sometimes status 14 and sometimes success but then it is not clear how to respond to a device which has no pincode.
We can not find any example or document which cleary explains the complete process and especially the process of attaching for example a keyboard or a device which has no pincode.
Thanks for help.
Part Number:AWR1642
Hi Team,
The customer is debugging the AWR1642 to configure the radar module. He observed through the spectrum analyzer:
But the interrupt count is not normal, the number of statistics chrip interrupts is less.
What caused this?
Thanks.

Part Number:DCA1000EVM
Hi Team,
The customer designed the 1243P board. He is now connected via the 60Pin interface on the DCA1000. There is no XDS100 module on the 1243P board. How can he use the mmWave Studio to collect 1243P ADC data through DCA1000?
Thanks.
Part Number:IWR1642
Hi Team,
Customer wanted to develop heart rate and pulse monitoring devices with IWR integrated boards. Customer found that two DEMOs were selected running IWR1443 via the training video. Can IWR1642 run these two demos? Also, there was IWR6843 development board. Can this run the demo on the training video? What is the difference between it and IWR1642?
Thanks.

Part Number:MSP432P401R
Tool/software: Code Composer Studio
Hi
I am using CCS V8 for programming the msp432p401r with FreeRTOS. When I am build the module I am facing the link error.
I have gone through the every link provided for the similar issues and have already done all including the files and etc.
I have followed the http://processors.wiki.ti.com/index.php/Include_paths_and_options also which did not give me the answer I am attaching the snapshots of the project below
There are no library files only clear .c and .h files and c functions which I am trying to integrate.
Thanks in advance,

Part Number:IWR1443
Dear Sir/Madam,
We are using IWR1443 for doing some RCS measurement. So we have done the measurement and during the measurement, we have gathered the raw data (.bin) file. I have tried to do some post-processing but unfortunately, I can't reach the same result of radar studio post-processing result.
I would like to ask it is possible to share the post-processing code with the customer?
Thanks in advance and best regards,
Sevda
Part Number:TPS25944L
Dear Sirs,
My customer use TPS25944L on their 5V input power rail and the output is 5V, that seems TPS25944L work well.
However, they found the PGOOD pin keep low always, but the 5V output is still existing.
Attached is the schematics.Could you help to review the schematics and give me some idea about it?
Thanks.

Dear Team,
Can MAX3232CPWR P2P replace ADM3202ARUZ?
If no, do we have suitable one?

Part Number:TPS62745
Hi Sir,
Please refer SCH as below, Vin=7.5V, Vo=3.3V, the Iin=5.5mA during no load, it's higher than datasheet quiescent current spec.
May I learn from you how we can improve quiescent current ?
Thank you.
