I am a very beginner in using OMAPL138. If my question is very basic please don't mind. Ï need a very clear idea on the basic things. The following are my doubts

1. Support for L138-FX-225-RC

I am using Mitydsp l138 for my project . The support materials provided by critical link the manufacturer of the above product is very less. Can i approach TI for the technical support ? If yes can you please consider my further doubts.

2. JTAG Emulator. From the block diagram https://www.criticallink.com/wp-content/uploads/2014/01/MityDSP-L138-Block-Diagram.png emulator is included on SOM . I am not able to find which emulator, critical link is used on board. Is this XDS100V2 ? If the above concept is wrong should i use an emulator externally.

https://www.criticallink.com/wp-content/uploads/2014/01/JTAG_Debug_Adapter.pdf

The above link says about the break out adapter used on the Mitydsp L138. Is there any need of further emulator externally ?

Hai,

i am using am5728 GP evm. i am looking for a way to enable only mic input from audio input jack only when a external button is pressed and again it should switch to its default state( i.e., audio output). So, how an external button can be used(connected to device) to control the audio input in this evm ?

Thanks & Regards

I use the DRV8303EVM board to control the brushless DC motor T-motor air gear 2213/920 kV. The measured maximum speed for this motor is around 11,500 rpm, however I could not reach this speed using DRV8303EVM. I am using InstaSPIN-BLDC_GUI_DRV83xx_v104 software in the velocity control mode. The parameters I set are: 0.01 for flux threshold, Kp = 10, Ki = 0.5, no. of poles =4 and freq. = 500 Hz.

Is there a maximum speed or what is your advice?

Thanks

Dear Team,

How to setup UCC2897A's OCP?

On the datasheet, it mentions output current limit is 32A

I think this 32A is cause by Rcs resistor and current sense threshold, right?

How to calculate it?

Hi,

I followed the instructions to get the BOOSTXL-BUCKCONV booster pack up and running together with F28377S launchpad. I am able to import the project into CCS (using CCSv8.2.0) from controlSUITE - either directly from controlSUITE, or from TI Resource Explorer Classic or via project import, but in all cases whenever I open main.cfg with xgconf I do not see the GUI, only empty white space.

I have seen a thread on e2e with similar issue, but in my case I do not have a jxbrowser task and I am also not able to copy and check the link of PowerSuite, because in my case if I right click PowerSuite in main.cfg (after enabling grace developer features) I only get "about:blank", so basically there is no URL copied, which I could check/follow in chrome for example.

Please let me know, how I can enable the GUI view of Solution Adapter from powerSUITE within CCS main.cfg xgconf view?

- CCSv8.2.0

- controlSUITE v3.4.9

Many thanks and best regards,

Gregor

A very basic question. I have my motor attached to the DRV8308EVM and spinning OK in open loop, sine wave commutation. I would like to try closed loop speed control, but when I tick the "enable MCU clock" box in the all registers tab I don't see a clock being generated by the MSP430? Any thoughts?

I created a simple project using Energy Measurement Design Center and library. Every went OK without any error and it created the CCS and IAR projects.

I want to build the project using CCS and the TI compiler, importing the project in CCS shoud satisfy this condition but when starts to link it exits because does not recognize the format of some IAR libraries.

I suppose it is a project setup problem because seems it is trying to link CCS and IAR libraries.

Any other engineer had the same problems?

Hello,

I'm working with a SimpleBLEPeripheral and SimpleBLECentral, running the examples all run ok, now I need to find the way to automatically connect a "specific" peripheral to the central.

I have attached a couple of sensors to each peripheral, so "specific" means the temperature peripheral, or light sensor peripheral, etc. each with a unique broadcasting name.

More concisely: if the central overhears that "temperature peripheral" is broadcasting it will automatically attempt to connect and retrieve the temperature data from the peripheral.

Although I'm not new programming, I'm working with TI BLE CCSv7 based. so any help will be greatly appreciated.

Thanks

Hi,

I am going to use Sensor Controller to read 2 Analog Sensors and 1 I2C Accelerometer Sensor every 1 minute. After reading the sensors, the application will send the sensor data to a bluetooth service. I have only the Device Information Service, and Custom Bluetooth Service for sending sending sensor data.

I am reading this "Integrating Sensor Controller Studio Examples to Project Zero" doc, as guide. The doc shows creating another task and using semaphores. Is it possible to integrate the Sensor Controller Code to Simple Peripheral without creating another task and using semaphores? Can I just use the Simple Peripheral task for this? How do I process the semScTaskAlert with using Event_post() or Queing Messages to wake up the main application.

Hi,

I want to use a timer just for IPU1 (period greater than 1ms):

How do I have to configure the timer in the dts file:

DISABLE_COMPLETE(timer11);

&ipu1 {

    mboxes = <&mailbox5 &mbox_ipu1_ipc3x>;
   status = "okay";
   memory-region = <&ipu1_cma_pool>;

timers = <&timer11>
};

ti,timer-alwon;

How I have to configure the interrupt:

The problem is that the IPU1 reacts only for TIMER1 and TIMER11 interrupts (crossbar is configured correctly). Why?
The interrupt is not equidistant (100ms-500ms)) and the timing is totally incorrect (70ms). If I am using TDA2Px without Linux, only CCS gel scripts then the timing is perfect (so timer registers are configured correct). (I am toggling an GPIO1 pin and measure it with an Oszi.)

Thanks for help
