PSoC™ 4 Forum Discussions

Dear's         

I follow these steps for programming your PSoC 4 Prototyping Kit using Bootloader Host.

    
1. Open the Bootloader Host Windows application
    
2. Press and hold the user button down on the Prototyping Kit and insert it into an open USB port on your PC.  The button must be pressed on power up to invoke the bootloader.  The amber LED should light up indicating board power and the blue LED should blink continuously indicating the bootloader has been invoked and it is waiting for a file to upload.
    
3. The Prototyping Kit should automatically enumerate and show up in the Ports window within the Bootloader Host application.  You may need to wait for the driver to finish installing.  If the port doesn't show up after the driver installs, click on the Filters button in Bootloader Host and make sure "Show UART Devices" is selected.
    
4. Once the Kit enumerates, select it in the Ports window.
    
5. Apply the following serial settings:
   

Baud:  115200
Data Bits:  8
Stop Bits:  One
Parity:  None

6. Select File -> Open

7. In the 'Open' dialog box, navigate to the CYACD file you created from your bootloadable project and open it.  It will be in your project directory under <project name>.cydsn -> CortexM0 -> ARM_GCC_xxx -> Debug. ( Problem 1:no boot loader file in Debug)

8. Program the Prototyping Kit by selecting Actions -> Program. (Problem 2: Programming option is not enable )

Each time you want to program the kit, you will need to unplug the board, press the button and re-insert it into a USB port to invoke the bootloader.  You will also need to re-select the proper COM port within the Ports window in Bootloader Host as it will disappear when you unplug the kit.

kindly help me to solve these to problem

I want to trigger ADC sampling @1000Hz with a Clock. However, I get a (for me) strange error:

Pin guidance unavailable: Invalid connection for clock "Clock_ADC_SAR_Seq" connected to "\ADC_SAR_Seq:cy_psoc4_sar\:trigger".

Pin guidance could not be updated due to an error. Fix the error to get updated pin guidance. See summary for details.

See attached image ClockToSOC.png . But if I connect it through a FreqDiv there is no error, see attached image ClockToFreqDiv.png . How do I trigger a SOC with a Clock @1000Hz?

Also: I see that the Clock symbol has a white square graph, but on other designs I had a black square graph. And I do not know where "summary" is.

EDIT: I saw that the Clock frequency was falsely set to "1000 kHz", but correcting it to "1 kHz" did no difference.

I'm interested in developing a Bluetooth Low Energy enable BLDC motor controller that uses Sensorless Field Oriented Control to handle the motor speed. 

Researching different alternatives I found this Application Note for the  that implements the Sensorless FOC technique in a Cypress PSoC 4. 

Is that same application valid for the PSoC 4 BLE? Can I run those examples on a PSoC 4 BLE?

I know I can have a dedicated PSoC 4 do the motor control and use an external BLE module to handle the Bluetooth Low Energy communication, but it would be nice to use 1 IC to do both things. 

My main goal is configure a GATT server that with different characteristic of the motor control, and use another device (a Smartphone for example) to set the motor speed. 

Thank you very much beforehand. 

Hi,

How to know if the BLE device is scanning in FAST mode or SLOW mode? In fact, for my particular case, I would like to know when exactly the device is advertising to blink a LED at the same rate.

Thanks,
