PSoC 4 MCU

I have a CYBT-213043-EVAL board and the  CYBT-213043-Mesh board. I downloaded the Eclipse  IDE for modus toolbox 2.2 and opened the Mesh application and the RFComm application.  I was successful building, programming and running both applications using the USB connection for each board.  I now want to modify and debug each application. I purchased and received the CY8CKIT-005 miniprog4  kit to accomplish the debug.   I downloaded the software for the  CY8CKIT-005 miniprog4 kit and I believe I was successful.  1st question, is this the correct kit to perform debug?  2nd question, is there documentation to show how to physically connect the 5 pin or 10 pin connector of the CY8CKIT-005 miniprog4  kit to the eval boards?  3rd question, is there specific manual for debugging? 

Hello,

I have created a trackpad using the PSoc 4 MCU that will be utilized as a BLE Mouse to control a cursor on a computer screen. I would also like to collect information on the position of the finger on the trackpad. Up until now, I have used the Launch tuner to log this position data, however, I would ideally like this to be done on a computer software. How can change the provided BLE HID Mouse code by Cypress to read information related to the position of the finger on the trackpad rather than the displacement?

Thank you,

Dear community,

i have a workspace containing 3 projects which are the Launcher, BLE OTA Update and Firmware. All projects with exception the launcher using BLE Component and ADC. I use the ADC to measure the battery voltage to use this value in the advertisement of 2 different projects. I would kindly like to know how i can implement my advertising-code in a separate project by using the BLE component and ADC? I would appreciate to edit this "library" code at any time. So dealing with binaries and copy them seems not a good option to me.

Thank you very much for information to solve this.

Hello.

Attached project uses 2 PWM components.

PWM makes square wave, and this square wave is stopped or started by PWM_Timer interrupt.

Attached pptx file is waveform of this square wave.

Sometimes it takes some time for voltage level to reach GND when square wave is stopped.

Please confirm red circle of attached pptx file.

Q1)

Could you please let us know reason why this behavior occurs?

Does this behavior occur if PWM is stopped when voltage level is high?

Why doesn't voltage level go to GND immediately?

Q2)

Could you please let us know solution to this behavior?

I want to immediately set voltage level to GND regardless of timing that PWM_stop is called.

Best Regards.

Hello,

in my application, I have a lithium battery.

the system is powered when USB is pluging in and a specific IC charge the battery?

the IC charger has two differents set up: 1:  limit the current at USB specifications (100 mA and 500mA after enumeration) and 2 :boost current more than 500mA (max 1800mA) when the USB cable is connect to a wall adapter.

I need to kown, when  this two different stage happen

_ when enumeration is ok and USB port can send 500mA

_when the USB cable is connect to a wall adapter.

is there fonctions in the API of the USBFS component that can handle that.

We have a product that uses the CYBLE-012011-00 with EZ-Serial 1.1.1 that is experiencing issues when sending data over CYSPP.

We are seeing an intermittent issue where it seems the module stops forwarding the data sent to it over UART while in CYSPP mode when connected to an Android Phone (OnePlus 7T Android 10).  Usually, the first 2 or 3 packets sent over UART after sent over BLE but after that, there are no more packets. The module is not completely non-responsive, when the phone doesn't respond to the CYPSS packets, we enter API mode to disconnect which works and then we reenter CYSPP mode awaiting connections. Following connection attempts from the phone do not work either.  I have verified that we are sending the same data over UART for the working and failing cases.

I have captured Wireshark logs a successful connection attempt and failing attempt and nothing stood out to me, an example of both is attached taken using the nRF sniffer firmware. See attached images (couldn't attach pcapng)

We do not see this issue when an nRF product connects to our Cypress module. Sometimes after the nRF product has connected, sent data and disconnected, the following phone connection works.

Is this issue related to 274727 mentioned here?

We are in the process of testing this on other Phones.

Hello

in my application the charger IC always feed the system and "disconnect" the battery when the charging process is finish.( ofr keeping a long life battery with less cycle)

So for my understanding, when a USB cable is plug into my device, my system is ALWAY bus powered.

Do I have to set my USB device as a self powered device, and just after the configured state, change into bus powered device ? or directly as a bus powere device ?

What about the hardawe configuration ? do i need external resistance for pull up or I just use the internal pull up resistance on D- and d+

Hi,

What happens to PSoC4 if RS-232 serial cable is unplugged during a bootlodable update by the bootloader via UART? Does the bootloader keep waiting for the next UART reception?

Since it's only halfway written to Flash, it may lead to corruption of the bootlodable. But if PSoC4 is reset and the Host System sends the bootloadable image again, I think it's possible to update the bootloadable.

Best regards

Hello,

We know that the "CE210291 - PSoC® 4 CapSense® Low-Power One Button" project transitions between Deep Sleep and Active mode to achieve CapSense with low power consumption. When the Deep Sleep current is measured using CY8CKIT-041-40XX with the power supply voltage set to + 3.3V, it is several μA.

On the other hand, when the Deep Sleep current is measured with the power supply voltage set to + 5 V and the VREF set to 2.021 V, approximately 350 μA is consumed.

Do we need to put VREF to sleep before executing CySysPmDeepSleep ()?

If the power supply voltage is + 5V and the Vref is 2.473V, the Deep Sleep current will be several μA.

We would like to adjust the gain of raw count value with Vref.

Best regards.

Hello, 

I have a PSOC 4 MCU with BLE 4.1

I would like to understand if there is a way to verify a write response was actually sent to a write request?

Today, I use this API function provided by cypress: 

CyBle_GattsWriteRsp(cyBle_connHandle)

The function is said to return the following options:

* \return
*  CYBLE_API_RESULT_T : Return value indicates if the function succeeded or
*  failed. Following are the possible error codes.
*
*  Errors codes                          | Description
*  ------------                          | -----------
*   CYBLE_ERROR_OK                       | On successful operation
*   CYBLE_ERROR_INVALID_PARAMETER        | 'connHandle' value does not represent any existing entry in the Stack
*   CYBLE_ERROR_INVALID_OPERATION        | This operation is not permitted
*   CYBLE_ERROR_MEMORY_ALLOCATION_FAILED | Memory allocation failed

So even if I get CYBLE_ERROR_OK returned, it doesn't necessarily mean that the response was sent yet. I understand that it just means that the request to send a response has been received successfully by the stack and it will now take care of it asynchronously. This is a problem for us because we need to reset the MCU immediately after receiving a specific write request. But we need to send a response before the reset, otherwise, it will cause a problem in the device that had sent the write request.

So we need to be able to know that the response has actually been sent. How can we know this?

Thanks,

Eyal
