Part Number:CC2533DK-RF4CE-BA

Hi,

We are using the CC2533 in a design coupled with a MSP430 as a target node.
And the MSP430 connect to CC2533 via UART.

Is there any sample code or document of target node for reference?

Part Number:AM5748

Hi,

Customized card: AM5748

SDK: processor-sdk-linux-am57x_04_03_00_05

The following figure is about the typec and typeA signal selection.by  hd3ss3212:

The TUSB322I device implements Type-C Configuration Channel (CC) logic on the USB Type-C port.

Use the CC pin to determine port connection status and cable orientation, role detection, and Type-C current mode control.
I want to know if there is a driver and device tree file for the TUSB322I in the SDK?

Respected sir,

                     Please reply as soon as possible. Its urgent.

                      I am trying to integrate  tcpecho example into my code. But as soon as i add Globals in rtos for NDK, it starts giving exception at following line.

 SSIDataPut(SSI2_BASE, adcTxBuffer[0]);
 while(SSIDataGetNonBlocking(SSI2_BASE, &adcresult))
 {
 }

                   Without NDK my code works perfectly fine. As soon as i try to add NDK it start creating problem. I have attache snaps of problem.

Hi TI,

I would like to know internal connection between speed pin and VCC.

Because speed pin is measured 7.7V when only VCC pin is connected and GND pin is removed.

Speed pin is connected 8.2k pull-down resistor from control board.

Please refer to the below test connecting the DRV10975EVM.

Part Number:DS90UB947-Q1

Hi!

Is it possible to use the DS90UB947-Q1 to serialize a 2 Open LDI outputs from a Graphics processor in to two separate FPD Link III signals? For example 2 Open LDI interfaces as inputs and get 2 separate FPD-Link III outputs that can be sent to individual displays with different deserializers, perhaps one DS90UB926-Q1 and one DS90UB928Q-Q1. Or do I need two different serializers such as DS90UB925Q-Q1 and DS90UB927Q-Q1 to use two separate displays?

Part Number:TMS320F28335

Hello,

        I was using the TMS320F28335 control card with USB EMU R3 Docking station. It worked fine .Suddenly, now I am getting connection error. While trying to debug a program using CCS, the following error message is coming up :

Error connecting to the target: (Error -1015 @ 0x0) Device is not responding to the request. Device may be locked, or the debug probe connection may be unreliable. Unlock the device if possible (e.g. use wait in reset mode, and power-cycle the board). If error persists, confirm configuration and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 8.0.27.9)

     I tried checking the XRS pin, but couldn't find the pinout on the Docking Station. Is there any documentation available for this? Is there any other hardware or software test to debug the problem?

Also, if the device is permanently locked,then which part of the card is getting locked? And is there any way to repair or replace the card in that case? 

Thanks

Hi,

I am trying to run the example: dmm_154sensor_remote_display_app.

I imported the project from the Recource explorer in CCS.

Building and uploading the project is successful, but the launchpad doesn't send any data over UART and I can't find the device using the LightBlue application on android.

When debugging, the program is stuck in the file: project_foler/Release/./../../../driverlib/chipinfo.c line 204 (0x00010BC6)

In this line of code:

eCAP should return the period, which means the timeout between two rising edges,

Could someone please help me to configure the eCAP so it could take two rising edges?

Part Number:CC2650EM-7ID-RD

Hello,

I'm trying to get the direct advertising to work on my two SmartTF06 dev boards with the CC2650EM shield. But I cannot get it to  work, maybe you can help me with a few questions.

1. Do I have to change the mode of discovery for the central device or should the directed advertising packets be found just like the undirected? At the moment I do not receive anything from the peripheral when directed advertising is enabled.
2. Should the directed advertising packet even be found by the central if there was no prior bonding? I other words, can I just use hard coded adresses on the peripheral side to address the central?
3. I found some threads in the forum noting that the address given for GAPROLE_ADV_DIRECT_ADDR should be reversed, is this true?

The SDK version is "ble_sdk_2_02_02_25".

I've started with the simple_peripheral and simple central and changed the following:

Peripheral:

SimpleBLEPeripheral_init(){

...  after all the GAPRole_SetParameter calls I added:

    uint8_t resolvedAddr[B_ADDR_LEN] = {0x00, 0x2f, 0xdc, 0x43, 0xb4, 0xb0};
    uint8_t idx = GAPBondMgr_ResolveAddr( advDirectAddrType, resolvedAddr, NULL);

    if ( idx < GAP_BONDINGS_MAX ){

        uint8_t advDirectType = GAP_ADTYPE_ADV_LDC_DIRECT_IND;

        bool bIsEnabled = false;
        GAPRole_SetParameter(GAPROLE_ADVERT_ENABLED, sizeof(uint8_t), &bIsEnabled);
        GAPRole_SetParameter(GAPROLE_ADV_DIRECT_ADDR, B_ADDR_LEN, resolvedAddr);
        GAPRole_SetParameter(GAPROLE_ADV_EVENT_TYPE, sizeof(uint8), &advDirectType);

        //GAPRole_SetParameter(GAPROLE_ADV_DIRECT_TYPE, sizeof(uint8_t), &advDirectAddrType);

        bIsEnabled = true;
        GAPRole_SetParameter(GAPROLE_ADVERT_ENABLED, sizeof(uint8_t), &bIsEnabled);

Display_print0(dispHandle, 5, 1, "bonded!");
Display_print0(dispHandle, 6, 1, Util_convertBdAddr2Str(resolvedAddr));
Display_print0(dispHandle, 7, 1, "Directed");

}

Central:

#define DEFAULT_DEV_DISC_BY_SVC_UUID          FALSE

For the Central the evaluation allows to list all the found MAC-Adresses but the address of the periperal device does not show up. Do you have any hints or can somebody provide a working example?

Best regards

Fabian

Hello,

I've got a DP83822 on my board - if I read register 0x16 (BISCR) after a reset it's always returning 0x0300 (Packet generate active).

I can reset via BMCR = 0x8000 or PHYRCR = 0x8000 or 0x4000 and it returns 0x0300 - the datasheet says the default should be 0 for bit(9) - why would this RO bit be set?

Dear E2E-Community, 

I'm trying to develop an  automated goldenfile transfer via LabView and an EV2300. 

I'm using BQ80xRW and I am able to read and write SMBUS and I2C Commands, but due to the poor description in the Help file attached to the EV2300 customer kit  

 (https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/196/2318.EV2300-Customer-Kit.zip) I'm not able to implement the golden File programming. 

There is a command called ProgramFromSrec and the only input parameter ist the filename/path... When I try this, the return code from the funktion is 221 and i don't know how to interpret this. 

For the other commands (ProgramSrecWithCfg and ProgramSrec) I dont know how to setup the input parameters. nProtocol, nPlatform, or how to setup the BCfg and the PCfg files. 

I woulld appreciate any help and please excuse my poor english.

Hi,

-I'm using CC1310LP and interfacing with external sensor.

-In my application, Main controller(Cortex M4) will  be in sleep mode most of the time and Sensor controller (RISC) has to be wake all the time reading the sensor values.

-When it crosses the threshold, through the sensor controller Cortex M4 has to be woken up and  send the data and should go back to sleep mode .

Is there any example code for in the SCS to wake up the controller during particular event and then Main Controller should go back to sleep mode.

Is Sensor Controller studio available for Linux ?
