Hello,

tms320f28335 0x3F 0400 ~ 0x3F 0800 User OTP area has 2KB. 

If I program about 1 KB space once in the OTP area, I wonder if the remaining 1 KB area can not be used.

Is it appropriate to program this area using the Flash API?

I wonder if there is no way to rewrite this area if it is an area that can not be rewritten once it is written.

Regards,

Han

Dear Support team,

Could you please support my question regarding the register descriptions in datasheet?

Q1. Are "0" and "1" at the bottom of the register bit field table such as Table 21 the default value after power on?

Q2. Table 19: BRG_CTRL, Table 20: BRDG_CTRL, Are the two above the same register?

Q3.  Fig. 28: Please tell me the default value of the BRDG_EN bit "

Q4. Table 19 has two DIAG_ENABLE registers (the third and sixth lines from the bottom). Does that mean anything?

Best Regards,

Hirokazu Takahashi

Hi Team,

            I'm AM3359 processor for my design.What is the programing process for the SPI flash if the primary boot mode setting is for SPI?

 Is the code downloaded from the AM3359 debug tool via the 20-pin header? Or do we need a separate header for the SPI flash?. Please clarify me query.

Regards

Hi community,

I have followed the instructions found here: http://processors.wiki.ti.com/index.php/CC3120_%26_CC3220_Capture_NWP_Logs

But I don't get any output. I'm using the LAUCHXL board connecting the P.62 to the J5 (on the side of the TM4C129). 

Application built in debug and loaded via UniFlash.

Am I missing something? Is there an example project for that?

Thanks in advance !

Hi Support team 

AS D/S page 23, 9.2.2.3 Input Filtering mentioned, 

Total effect on gain error can be calculated by replacing the 5-kΩ term with 5 kΩ – 30%, (or 3.5 kΩ) or 5 kΩ +
30%, (or 6.5 kΩ).

my customer just curious why the input impedance will have such higher tolerance about +/-30%?

if so, how about the internal divide resistor, is this part also has +/-30% tolerance? 

for example, 3.5Kohm will match with 350kohm & 6.5Kohm will match with 650Kohm? am i correct?

Hello Everyone, 

I have a LAUNCHXL-F28379D that its PWM3-B pin and PWM4-B pin are shorted to GND and 3.3V terminals. This situation leads to LAUNCHXL-F28379D board drains a lot of current and not work. 

Is MCU (TMS320F28379D IC) damaged? and should i replace it? or do you have any other solution?

Hi all, 

I've request from texas the samples of MSP430G2553& DRV8873S because I would to try it on my sample board and see how this component work with the GUI etc.. I follow the same circuit with the FT230X and the MSP430G220 but when I connect the USB to the PC it  recognise it as FDTI usb but if I use the CCS to program the MSP with the example firmware posted on TI website I cannot find the MSP. There's a dedicated program? If I use the DRV8873X EVM I see the correct COM port but the button CONNECT is gray and if I click on it nothing changes.

Thanks.

Lorenzo.

Hi Support team 

As D/S mentioned, the offset voltage is 2mV (typ) which mean the differential voltage would NOT less than 2mV to insure the output accuracy (less than +/3.5% max)

my question is that while differential voltage > 2mV, may we still need to consider this parameter (offset voltage) if we would like to calculate the output accuracy?

in the other hand, is offset voltage influence the output accuracy in normal operation mode?

Hi. My name is minhyung.

Currently MSP-EXP430G2ET + DLP7970ABP with Master kit
I am trying to make a custom device with RF430FRL152H.

It is a device that outputs LED light intensity received by Light sensor. After that we will reconstruct the Light sensor data to derive the final result. To do this, we need raw data. However, I found that it was impossible to get raw data from the RF430FRL152H GUI interface and save it to a computer. Is there a other way to do this?

And looking a little bit about it, I get to know that we need to know the baud rate of the UART. Can you tell me the baud rate of the master kit?

Thank you.

Hi,

I have made a custom board for a co processor. I want to use it as a gateway application. I would like to connect it with beaglebone black without a USB cable.

May i know how can i proceed?

For now i am trying to make it work with CC1350 launchpad. I have connected 3.3v, GND, RX and TX to beaglebone black from CC1350 launchpad. I dont see it working. when i start the colllector application, it shows  "Launchpad doesnt seem to be present" Can i get some help on making the launchpad work as a coprocessor without USB cable?

Thanks in advance.

Dear Officer,

We are using SDK2.1 running on AWR1642, and using mmWave_Demo_Visualizer  for our testing. When we try to use " LOAD CONFIG FROM PC AND SEND" option under plot, ver often we got missing chraters in the control port hence the device can not be start correctly. e.g.in the configuration file:

"lowPower 0 1"

But our device only got "Power 0 1" hence it will be treated as wrong command.

We did modify some algorithm but we don't touch on the cli.c tasks poart. Any suggestions why we can't get miss characters when receiving from control port from  mmWave_Demo_Visualizer? It is the loading too fast from mmWave_Demo_Visualizer? 

Tks and best regards
