Part Number:BQ24250

Hi Team,

My customer have some questions that I cannot find the answer on datasheet.

Please help to support the questions below:

1. Either pull CE# pin high or set 0x01[1] =1 can disable charge?

2. Will device follow ICHG at I2C mode? Will the current be limit by ISET at any moment? Or it will follow the lowest one?

3. What's the quiescent current at battery only? DS just show Iq of SYSOFF and High-Z.

4. Will the Iq different at battery only based on different CE# setting.

Thanks

Shaq.

CC3100: Variable g_PingPacketsRecv always returns zero

Part Number:CC3100

Wi-Fi Chip: CC3100

Hi,

  I am using the example "getting_started_with_wlan_ap" to configure the CC3100 as an access point. The security mode used is SL_SEC_TYPE_WPA. In the code flow, the code gets stuck at:

--

        if (0 == g_PingPacketsRecv)
       {  ASSERT_ON_ERROR(LAN_CONNECTION_FAILED);  }

--

  For WiFi client, I am using an iphone to connect to CC3100. When the iphone have connected to the CC3100 successfully, the ping is initialted and variable "g_PingPacketsRecv" remains zero. Is this normal if I am testing from a smart phone? What I might require to do to get the ping pass successfully?

Thanks

BQ40Z50-R1: Balancing LiFePO4 with bq40z50-R1

Part Number:BQ40Z50-R1

I am using bq24650 charger along with bq40z50-R1 for charging and management of 3 series cell LiFePO4 pack. Towards the end of charging, one cell voltage shoots up due to imbalances in SOC and then triggers Cell Over voltage protection. All the balancing arrangements I have seen and tried, takes hours to balance the cells, whereas this overshoot happens in seconds or minutes. Is there any way to tackle this issue ?

DS90UB964-Q1: Broadcast mode

Part Number:DS90UB964-Q1

Hello,

According to the data sheet "8.5.3 Broadcast Write to Remote Devices", if we run the
"8.5.3.1 Code Example for Broadcast Write" on UB964, I2C address of all serializers
(Ex.DS90UB913) become 0x0C. So, there are many seializers that same I2C address (0x0C) on I2C bus.
In this case, we can use the broadcast write, if we write the data in 0xC of I2C address.
This is my understanding about broadcast mode at DS90UB964.

I have some questions about broadcast mode at DS90UB964.

1. Why can DS90UB964 write right data to all serializer?
Please let me know the mecanisumu of this.

2. Can DS90UB964 receive ACKs from all serializer?

3. Can DS90UB964 confirm that I2C communication did not work, if one of serializer does not work?

Regards,
Nao

Hi,

I'm developing a contactless payments application with the CC3200 Launch Pad + TRF7970A Booster Pack, using the example code from here:   

My first challenge is to obtain a credit card number via NFC and have the following questions:

  1. Are credit cards ISO14443A Type 2?
  2. How do I retrieve the complete NDEF message from a credit card?
  3. How do I retrieve a NDEF record?
  4. How do I retrieve a NDEF record header?
  5. How do I retrieve a NDEF record header Identifier?
  6. How do I retrieve a NDEF record header length?
  7. How do I retrieve a NDEF record header type?
  8. How do I retrieve a NDEF record payload?

Thanks in advance for your help!

Hello,

We'd like to make OpenGL applications that works on Wayland. I think that latest Processor SDK Linux v3.3 doesn't have the build environment. Could you tell me what environment OpenGL demo applications in PSDK was built on? According to information from Imagination Technologies, their PowerVR SDK supported Wayland seems to be under development.

Hello support team,

Let me ask you following two questions from my customer;

1. In the appliation information of Figure 4 on datasheet, the polarity of external capacitor at VCC to GND seems to be opposite. Is this typo? 

2. If user use 1uF for all external capcitor instead of 0.1uF, is there any concern/problem on MAX208 characteristics?

Part Number:SN74LVC125A-Q1

Hello,

Is it possible to pull up VI to 8 Ω at 1.2 kΩ when Vcc is off?
According to the datasheet input and output negative voltage ratings may exceed if the input / output current ratings are observed.

Is it okay to exceed the rated voltage if the current is limited even on the positive voltage?
What is the current value in that case?


Best Regards,

Hi,

We have custom board designed using AM3354.

4GB (8 Bit) MMC is mounted on port MMC0. But we are unable to detect the MMC.-

Shows as no MMC present on MMC0 in UART boot mode

 

Question is- Can AM3354 detect 8 Bit MMC of capacity 4GB mounted on MMC port 0 ?

Please help on this isssue.

Hy everyone,

We just received our pre-flashed nand (Spansion S34ML02G100BHI1000) for our custom board....which however won't boot.

As I assumed there is something wrong with the ECC scheme I dumped the first page via nand dump.

The data itself is correct but the OOB data is not.

Dumping the first page of a "working" (i.e. successfully booting) device, I noticed different OOB data:

OOB:
        ff ff 40 a7 e0 4e a6 e0
        9c 95 ef dd 3e 6d df 00
        89 84 68 d5 90 5e 26 32

        50 ec ca 00 95 9e 33 59
        c3 a8 ac e9 86 17 b3 51
        38 00 ff ff ff ff ff ff

Can anyone explain the difference and what went wrong here?

Obviously the ff offset is wrong and in the "working" OOB data there is an additional 00 byte every 13 bytes.

Thanks and greetings,
Thomas

Part Number:LM74610-Q1

Hello

I have question about ISO7637 for LM74610-Q1

(1)
In the datasheet "Meets Automotive ISO 7637 Transient" is stated but is this the 2004 version?
Is this device also compatible with ISO 7637-2 2011 edition?

(2)
In the datasheet there is the test data of "pulse 1".
Are there the data of pulse 5a?

Best Regards,
Ryuji

Part Number:CC2564CMSP432BTBLESW

Hi,

 

BT stack: CC2564CMSP432BTBLESW

EVM: MSP-EXP432P401R + BOOST-CCEMADAPTER + CC256XCQFN-EM + CC3200AUDBOOST.

 

the step by step demonstration from HID Demo wiki link "" only describe demo between 'host' & 'device' using 2 sets of (above-said) EVMs.

Please advise how to test/demo HID profile between the EVM and Windows-based-PC / mobile-phone ?

How to configure the EVM as HID keyboard device ? and what's command (from the existing sample code) to send keyboard code (or string) from EVM to the 'host) ?

 

And, is there any sample application source code & step by step demonstration available for HID profile (over BLE) ?

 

Thank you.

   I download am57xx-evm-linux-rt-03.02.00.05 , and I use  Win32DiskImager to download the image into the SD card according the "Windows SD Card Creation Wiki". 

Then I insert the SD into the IDK and power on the IDK. there no outport from the serial port. It seems  the software is blocking.I wonder if this IDK is failure.

66AK2H14: Internal pull up and pull down values

Part Number:66AK2H14

Hi,

In the datasheet of 66AK2H14, on page 229, it is mentioned that- "Internal 100-μA pulldown or pullup is provided for this terminal "

Please let me know what does this mean.

Whether this indicates if I connect any external pull down/ pull up, the current that would flow through it is 100uF ?

Thanks in advance.

Regards,

Madhu.
