Hello Team,

   we have TLE9879 EVALKIT . I have some doubt related to this.

1. Initially the driver is able to one of our motor with FOC sensorless code. but we are unable to run other motor . As the motor parameter of both motor are different this may the reason.

I tried to change motor parameter from config wizard for motix mcu but not sure that changes is been replication in keil while loading program in chip. can you guide me what step I need to perform for updating motor parameter in config wizard to keil.

2. I want to run BLDC motor in sensored mode using hall sensor connection.

but on evaluation kit there is not direct indication given for hall sensor connection.

can you please tell where should I connect hall sensor connection so that motor can run in sensor mode.

Below is snapshot of eval board

I have designed a custom board using TLE9879QXA20, and I am using ULINK2 to code the board, however unlike EVAL KIT I dont have any debounce button on the board, MON button is connected to Vs through Rmon. After loading the code (BLDC_BEMF), my motor is not running. Similarly other codes like Blinky also are not running. What should be done to run the codes after loading them?

@Krupashankar 

Thanks to the Infineon team for sending in the working UIO stick; now, I can connect my custom board designed with TLE9879QXA20 through the BSL tool.

However, I have a few questions

1.   How can we debug the code and run it in real-time with the help of UIO STick?

2. Is there a way of selecting UIO stick in uVision debuggers to debug and use the microinspector pro?

3. What needs to be changed in examples of TLE9879QXA40 for them to run with TLE9879QXA20?

Thanks for your continued support.

Hello,

From the datasheet, Timers 12, 13: " maximum count frequency = peripheral clock"

About other timers I only find some "resolution" also expressed as a fraction of "Fpclk" which I don't understand.

Also, I couldn't find what the possible "Fpclk" range is.

I need to count 3 external frequencies (in fact two, gated or clocked by third) up to 8MHz.  I can't tell from the datasheet.

The other question is about 177C: Some places 350F is the "rounded" number to aim for, which is 177C. Will this shut-down at 175?

Thanks,

Cat

What is the default voltage at the VDDEXT and RESET pin when the Vs and MON pin are connected to the battery positive terminal?

During SWD debug, what is the voltage at the RESET pin?

If using a ULINK2 debugger, does VCC on ULINK2 need to be connected to the VDDP pin?

Hello,

I using BLDC motor shield with TLE9879QXA40 for Arduino.
I would like to know what parameters to choose for the BLDC motor in the wheel, in particular the gain Ki, Kp. I am running the motor in HALL shields->setMode(HALL, BOARD1); but after starting at almost zero speed it has no torque. How can I achieve a lot of torque at start-up?
Thank you Martin Fox
