Dear all:
We use 4024 as a multi-Capacitive touch key processor. It generate an interrupt signal when touch down event be detected.Now we need check response time of our mass product.Can you tell me how to test ?
There is a planstic cover on the touch key sensor which was connect to PCB by FPC.
Thanks!

Show LessHi,
I have opened the Temperature sensing project for CY8CKIT-147, but I have received the error on ADC_SCAN (Old version block), What can I do ?
See the attached file.
Show LessHi everyone,
I am currently facing a problem on making fft works using CMSIS DSP library. Basically, I want to convert real time data from my sensor into frequency data by using FFT CMSIS DSP library. However, it only works for the first loop. I debug the code and somehow the program is still running after the first loop but i cannot find the location of the code where the program is running after first loop (Step Over). Does the FFT messed up the memory location of every function in the program or i cannot call the FFT function more than one time? Thank you.
Show LessWe have a device, based on CYBLE-222005-00. The firmware was created long time ago, following AN97060, so that it allows OTA upgrade of the BLE Stack and the Application. Since then, the PSoC Creator Components have been updated several times. Firmware development was started in PSoC Creator 4.1 and later continued on – PSoC Creator 4.2.
I was recently doing a code review and checking the firmware generation flow. When I repeated the instructions from AN97060 for an OTA Upgradable Application with added Upgradable Stack OTA Bootloader, I discovered one difference in the “cm0gcc.ld” file.
In our project file we have:
CY_CHECKSUM_EXCLUDE_SIZE = ALIGN(675, CY_FLASH_ROW_SIZE);
while in the example, the same line is different:
CY_CHECKSUM_EXCLUDE_SIZE = ALIGN(685, CY_FLASH_ROW_SIZE);
The following questions arise:
1. Why is that? I do not remember changing that file. Does this value depend on the version of any of the PSoC Creator Components? For example, I see that the BLE Component in the example is of version 3.30, while in our project this component is of version 3.60.
2. Should I expect any problems as a result of using 675 instead of 685?
3. Is there any different way to determine and use a correct value for CY_CHECKSUM_EXCLUDE_SIZE than copying the “cm0gcc.ld” file from the example?
Show LessHi,
I am currently in the process of implementing a communication component in verilog. The component has 3 digital inout terminals. To this i want to attach 3 different bidirectional pins.
Throughout the communication process, i will need to change the drive mode of the pins connected to the terminals. How can this be achieved in verilog. Any hints are greatly appreciated.
regards,
Martin

Show LessHello all,
I would like to build a V/F ACIM motor control using Psoc4 .
The application is a a complete electronic motor control for door-opener and sliding-gates
The power of motors are: 250W and 500W sensor-less , three-pahse triangle , 230VAC.
The characteristic for 250W are : 4pole motor, winding res. 62 ohms , inductance 250mH,
triangle connection, 230VAC. BkemF(Ke) 5.5V/1krpm, Moment torque costant 0.82Nm/A,
total torque 2.38Nm/1400rpm , Max rpm 1800 , min rpm 300
Is there anyone interested in collaborating?
Has someone already created a similar application from whitch to develop ?
Thank
Best Regards.

Show LessHello
I see in the documentation that the microcontroller is
compliant with SAE J2602. My application requires LIN 2.0 and SAE J2602
Compliance. Can you confirm that by checking the as in the screenshot attached,
the code will be compliant with the J2606 compliance? Also, I read in the
manual that For PSoC 4 devices only, the LIN
Slave Component is certified by the C&S group GmbH based on the standard
protocol and data link layer conformance tests. A complete certification report
can be made available on request. Does this certification include compliance to
SAE J2606 Compliance? If yes, how can I procure this data?
I wish to change the CAN clock speed from 250KHz to 500KHz in real time. Where can I locate TRM information that speaks to the specific registers that can be modified?
