Part Number:CC2640R2F
Hello,
For our application we're trying to achieve sub-meter accuracy with a 0-15meter range and rssi alone isn't giving us the level of accuracy we want.
From what I read in the BLE stack userguide the limiting factor of the ToF accuracy is the 24MHz clock is that correct?
Could we not use a faster clock for the CC2640 device in order to get the sub meter accuracy we want?
best,
Kevin
Part Number:ADC32RF80
DEARS.
Customer is ADC32RF80 is designed and used.
Fs = 2949.12Mhz
Interleaving spur occurs at 2580.48MHz.
The frequency band you are using.
In this case, is it appropriate to use the command "Steps for freezing the corrector block" in "Freezing and Bypassing the Offset Corrector Block" of Table 120 of the data sheet?
.The value written to Address 6068 in Table 120 does not match the Register Map on page 70 of the data sheet.
Please Check.

Thank you.

I found the difference between the sample code below.
A.eZ430_TRF7970A_Demo_v_1_00_00
B.sloc297c TRF7970ABP_RFID_Reader_Demo
In these two codes, only B included 5ms interval at line 292 of iso15693.c.
Why only B include the interval?
I'm designing test program using code A, but there were a missing tags.
After inserting interval like code B, the issue was improved.
I'd like to know the reason why this issue was improved by inserting such a interval.

Hi,
I have an issue about Ethernet on AM3358 Sitara soc, the interfaces ETH1 and ETH0 are setup as RMII and only eth1 is working correctly.
Here is the pinmuxing/device tree used :

};I am using ti-linux-4.14 version of the kernel.
I made sure that gpmc_a9 is configured as RMII_CRS_DV in sma2 register by setting BIT(0) => eth1 is worlking fine
My issue comes from eth0 interface where I cannot have a stable link, it keeps staying up and down :
[ 1586.161861] cpsw 4a100000.ethernet eth0: Link is Up - 100Mbps/Half - flow control off [ 1590.321567] cpsw 4a100000.ethernet eth0: Link is Down [ 1591.361876] cpsw 4a100000.ethernet eth0: Link is Up - 100Mbps/Half - flow control off [ 1596.561539] cpsw 4a100000.ethernet eth0: Link is Down [ 1597.601846] cpsw 4a100000.ethernet eth0: Link is Up - 100Mbps/Half - flow control off [ 1600.721530] cpsw 4a100000.ethernet eth0: Link is Down [ 1601.761850] cpsw 4a100000.ethernet eth0: Link is Up - 100Mbps/Half - flow control off [ 1604.881528] cpsw 4a100000.ethernet eth0: Link is Down [ 1605.921842] cpsw 4a100000.ethernet eth0: Link is Up - 100Mbps/Half - flow control off [ 1608.001533] cpsw 4a100000.ethernet eth0: Link is Down [ 1609.041878] cpsw 4a100000.ethernet eth0: Link is Up - 100Mbps/Half - flow control off [ 1611.121534] cpsw 4a100000.ethernet eth0: Link is Down [ 1612.161882] cpsw 4a100000.ethernet eth0: Link is Up - 100Mbps/Half - flow control off [ 1615.281525] cpsw 4a100000.ethernet eth0: Link is Down [ 1616.321915] cpsw 4a100000.ethernet eth0: Link is Up - 100Mbps/Half - flow control off [ 1620.481540] cpsw 4a100000.ethernet eth0: Link is Down
The hardware PHY LAN8710i is set according to this checklist : 
Both interfaces are wired exactly the same way but I cannot get eth0 working.
Do you have an idea of where the issue is coming from ?
Thanks
Dear Sir/Madam,
Part Number:DRV8703-Q1
Dear, Sir.
My customer is evaluating DRV8703-Q1. During that, They are facing following
symptom on /SLEEP & /FAULT.
/FAULT Glitch(LOW) during aprox. several 100us ~ 1ms can be observed at
/SLEEP LOW<=>HIGH.
1. Is it a normal behavior which DRV8703-Q1 has?
2. If it was normal, Is it possible to define maximum duration of /FAULT=LOW?
Considering the solution such as doublle reading by MCU, the duration would
be significant. Please give your advice.
Best Regards,
H. Sakai
Part Number:TLK10002EVM
I installed the TLK10002EVM GUI on my Win10 computer and even without the USB connection to the EVM, the software indicator at lower right corner transitions from red (working) to green (ready). SLLU147 seems to indicate that means it has established an EVM connection, but there is none. When I attach the USB cable to the EVM, initially the USB LED "online" is green and the "suspend" is not lit but transitions to red after about 20 sec. The GUI gives no indication that anything has changed. Is there another way to check that the GUI and EVM are actually communicating?

Part Number:LM5005
Tool/software: WEBENCH® Design Tools
Hello guys,
One of our customers is considering using LM5005 for their new products. They want to simulate lm5005 by WEBENCH or other any way (TINA-TI or other). Their conditions are Vin=24V, Vout=-16V, Iout=0.5A.
Can lm5005 be simulated with Vin=24V, Vout=-16V, Iout=0.5A by WEBENCH? If it can not be simulated by WEBENCH, could you please tell me how to select external parts and simulate it with the external parts?
Your reply would be much appreciated.
Best regards,
Kazuya Nakai.
