LAUNCHXL-CC1352R1: Understanding Channel Masking in 15.4 Sensor and Collector.

October 2, 2019, 11:59 pm

Part Number: LAUNCHXL-CC1352R1

Hello,

 

I have some confusion regarding the Channel Masking mechanism in 15.4 Sensor and Collector.

I have two setups consisting of one 15.4 Collector and one Sensor_Oad each. I am using the Frequency Hopping mode (CONFIG_FH_ENABLE  - true) and hence used the CONFIG_FH_CHANNEL_MASK to form two different networks. I will be calling the Sensor_oad and Collector in 1st n/w as S1 and C1, similarly S2 and C2 for n/w 2.

I changed Config_Fh_Channel_Mask in S1 and C1 such that it should use only Channel 10. While for S2 and C2 I changed the Channel Mask to use Channel 12. But I noticed that if I start N/w 1(one using Channel 10) and then start just S2 (one using channel 12). S2 still joins the C1 which is using Channel 10. I tried various channel combinations but irrespective of the channel, the Sensor joins the Collector.

I know it is possible to bound two networks based on PAN-ID and CONFIG_COORD_SHORT_ADDR but is it possible to restrict or bound those two networks only on the basis of their Channels, so that they don’t interfere with each other?

Is this an expected behavior? I guess that the Collector is somehow sharing the information of its own Channel (just like Reporting and Polling Interval) and the sensor is using that information to update its channel of operation. Is this assumption correct? 

Or, are there any extra changes required to restrict the Sensor on its own Channel, so that it will only join the Collector which has the same Channel?

Thanks and Regards,

Yash.

CC3120MOD: UniFLASH 5.1.0 -> "Timed out waiting for ack"

Part Number: CC3120MOD

Hi,

I'm trying to program some boards with CC3120MOD devices on them.

If I use UniFLASH GUI, I can connect to the device, however when I program I get a timeout.

If I use UniFLASH CLI, I get the same problem.

Here is the command:

D:\TI\uniflash_5.1.0\simplelink\imagecreator\bin\SLImageCreator.exe project program --name spro --dev

Here is the start log (You can see it gets the storage list just fine):

INFO:root:FTDI not detected, trying XDS

Some info about building the image:

The products are available in : [d:\ti\uniflash_5.1.0\simplelink\imagecreator\bin\C:\Users\SNIP\.SLImageCreator\projects\spro\sl_image\Output ]

And finally everything pauses for a few seconds (I think its building the image) and then I get this:

Can someone please advise why I am getting the timeout?

THanks.

         as given in the datasheet to configure the L3GD20H sensor as SPI interface CS must be low (1: I2C mode; 0: SPI enabled)

i connected CS of L3GD20H to pin J9.3 (MIBSPI1NCS[0]) is it right to configure CS to be low (from SPI1 select SPI1 port  enable DIR of SCS[0] and DOUT =0)

or their is another way to do that

Hi,

. It is set to 100BASE-FX, but the link is established 201.5ms after reset release.

In this case, the measured link up time is 201.5ms, so can you say that the link up time does not exceed MAX300ms by looking at the margin from PHY's logic of several internal processes?

If MAX300ms is not enough, can you say that the link up time will not exceed MAX400ms?

ADS8866: External REF and AVDD/DVDD Power Supply Sequence

Part Number: ADS8866

Hi team

Does ADS8866 malfunction in the following sequence?

Power-Up : 30 msec after AVDD(3.3V) and DVDD(3.3V) rises, REF (5V) start rising.

Power-Down : After AVDD(3.3V) and DVDD(3.3V) decreases, REF(5V) gradually decreases over about 500 msec.

Do we need to control the REF sequence? Is it possible to keep the reference voltage power on regardless of the VDD status?

best regards

But I couldn't find the suitable ic from ti.com.

Spec: current sensing : 100mA~500mA (adjustable)

if current over 100mA~500mA, then output logic "low", if current lower than 100mA~500mA, then output logic "high"

Thank you for your help.
