BQ34Z100-G1: Remove Digital Temperature Control

≪ Previous: CCS: Buiding OTA library (LOCAL AND CLOUD OTA)

Hi,

I know there is no spec provision for updating temperature digitally. However, I would like to know if there is a way to update

internal or external temperature value digitally (via a flash update for example). Or this a firmware revision that may allow this as a command?

Having a the capability for a remote digital temperature sensor could be an added selling point for this component.

Can you help me in this regard? It is very important for my application. I have a remote sensing element that is not analog.

Hello,

Regarding the LVDS interface, does the LVDS clock run continuously or does it burst on and off when there is valid data?

Thanks,

Hi TI,

I am trying to get my TAS5755MEVM up and running. The Purepath GDE fails on startup. It gives me the following error:

Unable to create an instance of the process flow controller.

C:Program Files(x86)\Texas Instruments Inc\TAS57x1 GDE\ComponentCache\TAS570xAudioApp_TI_v1\PfcTAS570xAudioApp_TI_V1.dll not found

I have tried to search for this file on the TI website to replace it, but could not find it. I tried to repair the installation with the GDESetup.msi file, but was unable to solve the problem that way.

I was looking for what version of GDE I am using, but the program closes before I can get any information from it. I used the setup file version 8.0.50727.42

I have attached the error log to this post. Please let me know how I can repair this program and work with the GDE. Thank you

I'm trying to integrate the SCS code into a CCS project and am following the i2c light sensor example (although I cant get that to run in CCS for some reason).

I do have my code triggering an initial task execution, but am unclear how to keep executing the task at regular intervals.

In my SCS execution code, I'm calling

fwGenAlertInterrupt();
fwScheduleTask(1);

which runs repeatedly in the task testing tab.

Over in CCS, I am starting it up with:

    scifOsalInit();
    scifOsalRegisterCtrlReadyCallback(scCtrlReadyCallback);
    scifOsalRegisterTaskAlertCallback(scTaskAlertCallback);
    scifInit(&scifDriverSetup);

    scifStartRtcTicksNow(0x00010000);
    scifStartTasksNbl(BV(SCIF_I2C_TEST_TASK_ID));

which triggers the callback and unblocks the semaphore, at which point I can tell that I got an execution of the task and subsequently call

    // Clear the ALERT interrupt source
    scifClearAlertIntSource();

    //DO STUFF HERE

    // Acknowledge the alert event
    scifAckAlertEvents();

At this point, I "think" it should run another task execution in a second, but nothing happens. Am I missing something, or misunderstanding the execution process?

≪ Previous: SENSOR-CONTROLLER-STUDIO: SCS Task only runs once

Part Number:TMS320F28075

Tool/software: TI C/C++ Compiler

I am developing a framework for the TMS320F28075 that allows it to be reprogrammed from an RS-485 connection. I created two projects in CCS with .cmd files configured such that their flash program memory would not overlap. The first project is generic code that simply toggles an LED (but theoretically can have any code that fits into its program space); it occupies flash sectors C through J. The second project contains routines that allow it to erase, flash, and verify the sectors from the first project from commands over the serial port; it occupies flash sectors A and B. In this second project, I modified F2807x_CodeStartBranch.asm to jump to an .asm file I wrote (instead of jumping to _c_int00). This .asm code checks if the first memory location in flash sector M (configured as a data section in both projects) is set, and either jumps to the beginning of flash sector A (to boot to the the second project) or sector C (the beginning of the first project). Doing this allows me to make the processor to boot to either project depending on whether or not flash sector M is erased (obviously, both projects have code that allows me to flash data to or erase sector M; the processor will boot to the corresponding project after a power cycle).

I first tested this system by programming both projects to the TMS320F28075 using CCS (I changed the flash settings so that the flash sectors belonging to the other project wouldn't be erased). With both projects loading onto the same chip, I then used my RS-485 host to change the value stored in flash sector M, allowing the processor to switch between projects (I verified this by coding different LED toggle routines on each project). So far so good, I was able to get both projects to coexist and switch between them.

The next step was to erase and reprogram the flash sectors corresponding to the first project from the second project (rather than doing this from CCS). I generated a .hex file that my RS-485 host could read, and used the data to complete a programming sequence. However, when I switch to the newly flashed program sectors, my code fails to execute (i.e. none of the LEDs blink). My first thought was that some of the program data must have been flashed incorrectly. I changed the flash settings in CCS from "Erase and Program" to "Verify Only", but the verification completes successfully (indicating that my host did flash the program data correctly). Furthermore, using Debug after "Verify Only" allowed me to step through the code and use the memory browser. I compared exported data from the memory browser from my flash routine (non-functional) against data after reprogramming from CCS (functional). Again, I was not able to find any differences between the flash sectors, though clearly something must be different due to the difference in behavior. When stepping through the code (using "Verify Only" after reprogramming from my utilities) I did notice some anomalies such as the clock_source switch statement jumping to INT_OSC2 even though the variable in Debug showed clock_source to equal "XTAL_OSC". I checked the .switch section in map and found that the section was left uninitialized despite setting it to FLASHJ in my .cmd file.

I've attached the .cmd and .map files for both projects. Any suggestions would be greatly appreciated (I changed the file extensions to .txt so I could attach them here).

Hello.

I have modified project zero and the BLE + Sensor BoosterPack tutorial to create a packet handshake program.
I have one service initialized by project zero init. The service has the following characteristics:

VoltagePacket (20 bytes) read only &

HexLogic (1 byte) write with response

I will post the while(1) loop where a packet load variable is modified and then passed into the VoltagePacket loop. EventPend waits for EventPost and then should run.

I know that event post is killing the connection. I moved eventpost to the buffervoltage_readattr and the buffervoltage_writeattr. When I moved it the writeattr, the connection was killed when I tried writing into a characteristic. When it was in readattr, the connection was broken whenever I tried to initiate a read.

P.S. I am reading the data from my IOS device.

I am in the process of porting code that was originally written for a Stellaris processor over to a TM4C129X chip. I came across the following code in the board initialization:

    /* Disable Ethernet */
    if (SysCtlPeripheralPresent(SYSCTL_PERIPH_ETH))
    {
            SysCtlPeripheralEnable(SYSCTL_PERIPH_ETH);
            SysCtlPeripheralReset(SYSCTL_PERIPH_ETH);
            EthernetInit(ETH_BASE);
            /* wait for 100ms - undocumented */
            SysCtlDelay(SysCtlClockGet()/30); /* 3 cycles per loop count */
            EthernetPHYWrite(ETH_BASE, PHY_MR0, 0x00000800); // Power down
    }
Is it really necessary to enable the Ethernet peripheral and explictly set its Power bit in the control register in order to save on power consumption? I would have thought that unless you enable the peripheral, it would not draw any power.
