Hi,
Regarding the GND electrode and the shield electrode, the mesh width and the distance between the meshes are described in the reference manual in a fixed manner.
What is the rationale for this value?
Also, what are the negative effects of using a solid pattern instead of a mesh for the shield electrode?
Regards,

Hello,
I have two different MCU's of cypress, CY8C4148AZI-S455 and CY8C4146AZI-S433, dealing with ADC_SAR_Seq.
I have noticed that I connected related ADC Pin to the ground, i.e short circuit, I saw 65535 ADC value on CY8C4148AZI-S455, and 20 ADC Value on CY8C4146AZI-S433 via uart protocol. What is the root-cause of such a difference ? Why am I acquring 65535 ADC value which is out of my range resolution (expecting min value ADC 0 and max value ADC 2047). I have attached top design configuration as below.
Any help would be appreciated.

I'm looking at two parts, one has a 'T' suffix in the part number and one does not. I've searched around and can't find what the difference is for my life. Does anyone know?
Specifically, the parts I'm looking at are CY8C4248LQI-BL583 and CY8C4248LQI-BL583T
Show LessHello,
Looking at J9 at SCHEM1 seems to represent J9 on SCHEM2 which seems to suggest that depending on the jumper of J9, the PSoC 4 and PSoC 5LP chips will be powered by either the USB's 5VDC or the 3.3VDC via the LDO power supply system. The jumper chosen on J9 will represent the VDD volatge throughout the parts connections. (Please confirm if I am assuming this correctly!)
In SCHEM3, we have VCCD??? Where does this come from???
Thank you
All help appreciated

Show LessI tried to connect CY8CKIT-42-BLE-A with CYALKIT-E04 by reffering the CYALKIT-E04 S6AE102A and S6AE103A Evaluation Kit Guide, A.3: Programming Using PSoC programmer.
But the firmware programming of BLE dongle was failed due to this error: "The hex file does not match with the aquired device". The hex file I used is BLE_Dongle_256K.hex.
I don't know the cause of the error. Should I use other hex file?
Also, I would like to send door sensor data over BLE to dongle by using the door sensor included in the sensor board of CYALKIT-E04 kit.
Do I need other firmware program for that?
If anyone has some examples, I would appreciate if you share the example.
I am very grateful for your advice. Thanks in advance.

Show LessHello, further to a question I asked (https://community.cypress.com/t5/PSoC-4-MCU/Reversing-proxmity-sensing/m-p/270896#M39101). After weeks of testing, I found that the CapSense values are very sensitive to the voltage of the power supply. At 3.8v the raw value could be 8000, while 3.7v could be 1000 and even lower when approaching 3.6v.
Since my system runs off a 3.8v battery as the power supply (connected to VDD of CY8C4245 directly). Is there any way to get a stable value from CapSense even the supply voltage drop a little? Like an internal regulator or something?
Thank you!
Show LessHi all,
We are facing one issue of hanging touch panel.
When capsense is not working, other ISR is working.
How can I detect a fault in cap sense ?
How to get an error code in this situation?
How to solve this issue ?
Show LessShould I use the api "CapSense_Stop()" before "CySysPmDeepSleep();" and after WDT wakeup use "CapSense_Start()"?
If I don't use these two api , CapSense_NOT_BUSY == CapSense_IsBusy() can't pass. When I use the api "CapSense_Start()" ,the current increase 200 ua.
Show LessHello,
I want to use the AN89056 Ram test in my project. I have copied all the required files from the AN89056_Ram test in my custom project. I have also compared the build settings of Project AN89056 Ram-test and make them equal but it is giving an error.
--undefined reference to MArch_Test_init
--undefined reference to MArch_Test_SRAM
this function is in "CyLib.h" and in assembly but the project does not find a reference. Could you please help me regarding????

Hello Team,
Kindly let us know if CY8CKIT-042-BLE kit supports simultaneous multi keypress functionality. If yes you can share an example code with us.
We have a requirement wherein we have to press two keys (e.g. Menu up + Power on/off) simultaneously for 10 seconds to pair kit with the BT Device.
We have seen BLE HID keyboard example but it sends only one key at a time.
