Part Number:CC2538
HI All,
On our custom board, we have CC2538SF23 device and using TI RF tool we can able to check the RX TX data on SmartRF tool with SmartRF board
after that, we want to flash the CC2538 device with our. out file by connecting smartRFEB to PC
CC2538 to smartRF board connection as usual thru 10 pin JTAG cable
we are successfully able to erase the device memory - i tried by mass erase options and it works
but after selecting the .out file for the program and click on RUN button
Flash programmer tool crashed and the showing following message
and .out file attached

Part Number:ADC12J4000
Hello everyone.
Got some questions about ADC12j4000 digital down converter.
While looking through datasheet I've found FIR-filters coefficients used in DDC (Table 9 at p. 36).
Decided to have my own try to model these filters in MATLAB software.
As it said in Table 8. at p.35, for Desimation Setting equal to 4, it uses cs19 and cs55 cascade.
Here is short MATLAB code for modeling that:
c19 = (1/(2*16384))*[22 0 -174 0 -2429 0 10029, 16384, 10029, 0 -2429 0 -174 0 22];
c55 = (1/(2*262144))*[-37 0 118 0 -291 0 612 0 -1159 0 2031 0 -3356 0 5308 0 -8140 0 12284 0 -18628 0 29455 0 -53191 0 166059 ...
262144 166059 0 -53191 0 29455 0 -18628 0 12284 0 -8140 0 5308 -3356 0 2031 0 -1159 0 612 0 -291 0 118 0 -37];
c19f= dsp.FIRDecimator('DecimationFactor',2,...
'NumeratorSource','Property',...
'Numerator', c19,...
'Structure', 'Direct form');
c55f = dsp.FIRDecimator('DecimationFactor',2,...
'NumeratorSource','Property',...
'Numerator', c55,...
'Structure', 'Direct form');
c19c55 = dsp.FilterCascade(c19f,c55f);
fvtool(c19c55);
And that's a MATLAB response:
And the problem is that it differs much from filter's perfomance, given in datasheet (Figure 36, p.23):
Could anyone help me with this? Probably I'm doing something wrong.
If there exist a full MATLAB or Simulink model of ADC(not necessary exactly that one ADC) with DDC, it would great if you share it.

I need to measure width of the air gap(0 to 10mm) between two metallic (iron) rectangular bars(L=infinite;W=10cm;thickness=20mm)facing each other. Though the surfaces face each other in parallel manner, the angle between the faces varies from 0 to 45 degrees. Can TI sensors provide any means to solve my problem?
Thanks,

Part Number:TPS40210
Tool/software: WEBENCH® Design Tools
Dear Community,
I used a design created by WEBENCH using TPS40210 to get a boost output voltage. I used the schematic, BOM and everything from the WEBENCH tool. I had built my board and it doesn't seem to give a boost output voltage, it gives me the same input as output. I haven't connected any load yet. Is there anyways I could debug my circuit to get the preferred result ? or where did I go wrong ?
Input = 9-28V (I gave this range of voltage)
Expected output = 50V
Thanks
Part Number:WL1837MODCOM8I
Hi All,
I am currently working on wilink 8 (1837 module) MCP 8.5 linux driver. I am bit confused with the INI file (tiwlan_18xx.ini) parameter called Board Type under Phy Mac parameters whose value is set to 0x02.
Board_Type = 02 # EVB_18XX = 0; DVP_18XX = 1; HDK_18XX = 2; FPGA_18XX = 3; COM8_18XX = 4;
I have seen some of the forums mentioned the board type value should be 0x04. Can anyone tell me what is the difference between the values 0x02 and 0x04 and which one to use?
What will happen if i use the wrong board type value?
Looking forward for the replies.
Best Regards,

Part Number:BQ24190
Hello,
I'm using the bq24190 charger in combination with the bq27542-G1 fuel gauge as battery management for my project.
Both chips are mounted on a PCB (reference design) and are connected via I2C with a MSP432 launchpad.
When plugging in a USB smartphone charger there is a short glitch on ground which triggers interrupts on the MCU (see figure 1).
(Please visit the site to view this file)
When using a power bank this glitch is much smaller (see figure 2)
(Please visit the site to view this file)
In general while charging with more than 1A the I2C bus causes a stuck on the MCU.
Does anyone have any suggestions what I can do against these glitches on ground?
Thank you for your help!

Hello ,
I am a newbie to microcontrollers. I started learning about ADC configuration from example "adc_soc". I didn't understand the following. please help
/ Wait for ADC interrupt
for(;;)
{
LoopCount++;
}
}
why LoopCount++ loop is required?
__interrupt void adc_isr(void)
{
Voltage1[ConversionCount] = AdcResult.ADCRESULT1; //discard ADCRESULT0 as part of the workaround to the 1st sample errata for rev0
Voltage2[ConversionCount] = AdcResult.ADCRESULT2;
// If 20 conversions have been logged, start over
if(ConversionCount == 9)
{
ConversionCount = 0;
}
else
{
ConversionCount++;
}
AdcRegs.ADCINTFLGCLR.bit.ADCINT1 = 1; //Clear ADCINT1 flag reinitialize for next SOC
PieCtrlRegs.PIEACK.all = PIEACK_GROUP1; // Acknowledge interrupt to PIE
return;
}
I have understood that adc_isr function is called in the " PieVectTable.ADCINT1 = &adc_isr;"
but what is the fuction of it and how come the loop is continuing?

Hi all,
I need to send data in 10kbps. But i also need long range. I thought about using 5kbps, SimpleLink Long Range mode.
Q1: If i change its data rate from 5kbps to 10kbps, is this mode remain still long range? (i should also changed its deviation and rx bw filter)
Q2: Which mode can you suggest to me for sending 10kbps data for best range?
Best regards.

Hello,
I am using simple peripheral project and I want to use PDM drivers. By default, there isn't any defined search path for PDM library in "File Search Path" section in linker options for simple_peripheral_app project. I added "C:\ti\simplelink_cc2640r2_sdk_1_35_00_33\source\ti\drivers\pdm\lib\pdm_cc26x0r2.aem3" library into the "File Search Path" section. Is it correct library?
Additionally PDMCC26XX.c and PDMCC26XX_util.c in simplelink_cc2640r2_sdk_1_35_00_33 seem heavily modified, if compared to sources in tirtos_cc13xx_cc26xx_2_20_01_08. Is there any significance that we should pay attention?

Hi to all,
I am using smart RF06 development board to program simple ble peripheral project.when i run it, "advertising" is displayed on LCD but when i enable the Bluetooth in a smart phone the name is not being displayed in smart phone what could be reason.any help appreciated.
Below attached is the simpleblepheripheral.c file
Part Number:CC2640
Hello,
we will use CC2640RHB in a custom board in external regulator mode. The supply voltage to VDDS and VDDR will be 1,9V.
Which maximum output voltage can we get?
Which maximum output voltage if we use push-pull output?
Is there a description in datasheet for losses?
Regards,
Chris
Part Number:TMS570LS1224
Hello Team,
In our product we are using Halcogen for code generation. whenever we modify the halcogen GUI, the Source and Include folders will be modified by the changes made in the GUI(it is expected).
Now i have a question regarding Halcogen GUI
1) Is there any way by which the changes in Halcogen GUI will not be reflected in the Source & include files??
2) Is there any way by which my code will not be changed against any Halcogen GUI changes??
I see this as a limitation because any one can change the halcogen gui which will change the functionality of the code. Any way to counter resist this halcogen changes??
Thanks In advance
Part Number:SN74LVT16244B
Hi dear supporting team,
is there any pull up or pull down circuit at SN74LVT16244 input? tks a lot!
Part Number:LMT85
I am using an LMT85 as a cold junction sensor (actually two) for thermocouple measurements. The LMT85 is interfaced to an ADS1248. It is required, that the PGA AINN or negative input of the differential measurement, be at least 100 mV above AVSS. I posted a similar question on the Precision Data Converter Forum. Joseph Wu was kind enough to reply with his thoughts and suggestions.
I suggested basically lifting of floating the ground of the LMT85 with, let's say a divided down voltage of 200 mV through a buffer op amp. Heck, the LMT85 needs 10 uA of supply current. An op amp should sink that easily, times two.
However, Joseph actually suggested placing a diode between the LMT85 ground pin and the circuit/system ground. I quickly tired this using a 1N4148, and a couple LMT85s. Appears to be working fine. The differential measurement of each LMT85, represents room temperature fairly closely. Has anyone tried this? Is it a good approach as interfaced to an ADC with integrated PGA?
Operational note: the LMT85 will be used to measure ambient between -20 °C and 55 °C.
Thank you.
Part Number:CC2640
Hi all,
I am starting CC2640 development on my custom board (using the CC2640MODA module). I am wondering if I can use my Segger JTAG edu for debugging CC2640, or it just doesn't with it?
Also, Does it only work with a specific Development tool i.e. IAR or will it work well with Code Composer as well?
Thank you all for your kind responses.
