Part Number:PCM2900

Hello

I am facing an issue with the Vcom pin which is not able to deliver enough current. I am not using a lot ~ 100uA

I was wondering two things:

1) What is the maximum current I may sink from this pin.

2)May I provide to this pin an external voltage reference? Or should I provide an external voltage reference to the Vccci pin and then use the Vcom (and expect to get enough current)?

Thanks

Nicolas

Part Number:CC2564MODN

Hello,

We use a CC2564MODN on our new product. This product has to constantly scan in BT classic and BLE to detect when paired devices are powered on, in order to establish connections as soon as possible.

To acheive that we perform in loop an inquiry mode for 5 seconds followed by a LE scan for 5 seconds. Interval and window are set to 11.25ms.

In the long run, the CC2564MODN  does not seem to support this high rate scan. All our boards end up to lost permanently their HCI communication randomly in a time window of 8 to 36 hours.

When this happens, the host cannot communicate with the module as the module does not reply to HCI commands anymore. At the same moment, the module TX-debug printouts many errors:

Here is one of our lgr files: (Please visit the site to view this file)

Here are the setup details:

- module CC2564MODN,

- host iMX 283, Linux kernel 4.8.6

- UART set to br 3000000

- BTS file is (Please visit the site to view this file)  (manual merge from initscripts-TIInit_6.7.16_bt_spec_4.1.bts and initscripts-TIInit_6.7.16_ble_add-on.bts)

- Bluez 5.45

Here is the scenario:

1- boot linux 4.8.6 kernel

2- load BTS file and attach hci interface thanks to this linux command: hciattach -s 115200 /dev/ttyAPP0 texas 3000000

3- start bluetoothd (bluez 5.45) in dual mode (LE + BT)

4- bluetoothd is set in discovery mode (continiously alterning inquiry mode and LE scan every 5 seconds)

5- after few hours in discovery mode (randomly between 8h and 36h), the CC2564MODN stops returning HCI event status

- a LE scan disable command is sent to the CC2564MODN to stop the current LE scan,

- the event status is not returned from the CC2564MODN,

- the HCI logs from TI logger displays errors at this exact same moment instead of displaying the LE scan disable command from host,

- the CC2564MODN does not answer to any HCI commands anymore

6- a hardware chip reset is neccessary to retablish HCI communication

Thank you for your support,

Is it possible to encrypt C2000GANG? The goal is to prevent reading the program  out of the C2000GANG

Part Number:AMC1200

Hello,

A customer pointed out that the wiring in Figure 36 of AMC1200 datasheet may be wrong.

The wiring in Figure 36 is slightly different from Figure 32.

In Figure 36, GND1 does not connect to the node between high-side and low-side FET, but it connects to Load instead.

Is this correct or wrong?

Thank you.

Part Number:MSP432P401R

Hello,

I have a Launchpad kit msp-exp432p401r with booster pack boostxl-edumk II which has a crystal display 128x128(CFAF128128B10145T).

I have created an application and are able to interface with this display and i am  displaying messages and images using the driver available for this display using GRLIB drivers from TI .

Now we are planning to change the LCD display to CFAF240320X0-020T which is 240x320 2 inch display.

Now our question is whether the same drivers are compatible with this display(CFAF240320X0-020T) by changing the command set  which has same SPI interface as earlier display?

or does it requires new drivers?

Hi Team

I am working on Power Bank that has wireless charger as well(15 watt).

if I placed the charging coil over the batteries, is there any risk factor ??

Does this affect the efficiency ??

(I am wondering that wireless charger generates the Heat at the time of charging and this might be risk factor, if I placed coil over batteries)

hi:

In the datasheet of opt9221, " near zero values indicate pixel pixel".

Ambient data is 6, how should I adjust to make "Ambient data" larger?What are the parameters that affect Ambient data?

I also want to ask how to raise the “Amplitude data "?, now "Amplitude data" is small, affecting the measurement range of opt8241.

Thanks a lot,

Hi,

Below is my circuit, M_USB_DM, M_USB_DP are connected to controller (TMS320F28069)

When I connect Mobile phone for charging on connector J9, the 5V supply draws 0.47 A current and in 5 seconds drop to 0.1A current, then again rises to 0.47A current. This fluctuations happens repetadely.

Kindly suggest reason for the current switching.

Hi, 

They all enter the constant current mode when the current exceeds the limit. The major difference is the Vin level, eFuse is higher than "Precision Adjustable Limit Switch". Are there any other difference?

Hello there!

I've spend some hours troubleshooting and want to ask what I've done wrong/ share my experience:

I tried to share some files between projects and therefore wanted to move files from the project-folder to another location. Then i added the files back in as a linked resource. When i added header files, CSS convenitently asked me if it should adjust the build path to incude the file i was about to add.

Here comes the problem: when clicking yes, my project got messed up and cannot be built anymore.

"No rule to make Target"

"Target not supported: devkit.target.Generic"

In contrary, if i add the include path myself, no error occurs.

Cheers,
