PSoC™ 4 Forum Discussions

Hello,

My design is based on two simple buttons.

When I disconnect the sensor,CapSense_CSD_sensorRaw[0]  or CapSense_CSD_sensorRaw[1] will turn into 0 with little probability.

Many thanks in advance,

Joe

Hi,

I am using an RTC component in my progect,and I want to know if there is any way to compensate for the crystal frequency error from its nominal frequency of 32.768 kHz.

thanks first.

I have PSoc 4 BLE- A, I would like to create a Project to determine ambient temperature based on Thermistor. Also would like to display that value on 16Bil GLCD display. I found few project but not related with PSoc4 BLE-A. Does anyone has idea how to create that project? Your response will be highly appreciated.

Hi all,

Had anyone interface PSoC 4200-L with EEPROM?

Be it I2C or SPI, I had this 2 type of EEPROM on borads for different store function.

I had try using the SBC mode, but look like is different from communication with the EEPROM.

More of the communication between the PSoC chip, processor to processor.

Hello,

This is the first time I write to the cypress community. It is a great place to find the solution to most PSOC problems.

I having problems using the em-eeprom on a PSOC 4 (CY8CKIT-049-42xx)

I have attached the complete project for you to see. It is a simple device that moves a hotmelt glue doser a few millimeters with a stepper motor (the project is not finished yet)

It has a lot of switch and a LCD character screen to set up 5 different parameters. I want to set the parameters and store them on flash to keep them on power cycles.

But it doesn´t work. I have read all forum thread on em_eeprom but I cant find the problem.

When I debug the project (using a kitprog from another kit) I see that the flash area is modified when the eeprom_write function is called. it is stored on the 184C address, and I do see it modified with the ram buffer data.

But this doesn´t happens on the target circuit.

Anyone find something wrong on the program?

Thanks in advance to all of you!!

I have two CyBle modules in the project. One is the client (master) and the other server (peripheral). Upon power up, the peripheral updates all of the custom characteristics with specific values. I can connect to the peripheral with CySmart app and read/write to each characteristic so that side of things works great.

On the central side, once it is connected to the other CyBle module, when I press a button on the central device, it sends a value to the peripheral and then the peripheral performs a function. I have a need to read a couple of the characteristics from the peripheral to be used in the client to alter the type of message being sent. I know the handle of the characteristic I want to read from so I try to use the function as follows

readReqParam = 0x0010;

bleApiResult = CyBle_GattcReadCharacteristicValue(cyBle_connHandle, readReqParam);

When I call this function in my main program, I get the invalid operation error code and the system locks up every time.

I have no problem writing from client to server but reading from server to client is not working at all. Not sure what is wrong or why. I added the event handling

case CYBLE_EVT_GATTC_READ_BY_TYPE_RSP:

             readResponse = (CYBLE_GATTC_READ_BY_TYPE_RSP_PARAM_T *) eventparam;

but that is never reached.

I dont believe anything needs to be done on the peripheral (server side) since I can read any characteristic from the app. Since I am able to write to the server using a known handle, I dont think there is anything wrong because that works ok.

This is extremely frustrating why a simple read is not working, help is greatly appreciated.

Thanks

I am pursuing BT certification with a third party.  They have indicated that the Cypress chipset (CY8C4127LQI-BL473) is already SIG certified.  How do I know if I can use this certification?

We use the design contained in the app note with the MIFA Antenna.  We use a custom profile.

Thanks
