Hello, 

I am designing a capacitive sensing trackpad using the CYBLE-214015-01 module. I notice that when I have my finger also touching the battery, the trackpad works great to control the cursor of my computer use the BLE HID Mouse Trackpad code provided by Cypress. Conversely, when I am not physically touching the battery, the trackpad works poorly. Do you have any insights on why this is the case? I have added a hatched ground plane to the front and back layer of the PCB as well as solid ground planes to the two middle layers of the  PCB. Originally, I thought it was a grounding issue, however, I have maximized the amount of ground planes I can add to my design. I also added the 560 ohm resistors to each of the CapSense pins.

Thank you.

I am trying to compile a C/C++ makefile project using the Eclipse IDE for ModusToolbox (Version:  2.2.0, Build ID: 2181) for CY8CKIT-062-BLE  target.  I am able to compile  *.c and *.cpp files but *.cc files  is excluded from the compilation.

If I add following in the Makefile:

SOURCES = $(wildcard extlib/*.cc) 

The build console displays following error message:

../mtb_shared/core-make/latest-v1.X/make/core/build.mk:386: *** Incompatible source file type encountered while constructing explicit rule: extlib/utils.cc. Stop.

I downloaded the cyfx3ad9269 example file posted on the forums here:  https://community.cypress.com/t5/USB-Superspeed-Peripherals/how-to-read-asynchronous-data-to-FX3/td-p/101517?start=0&tstart=0

Unfortunately, the example doesn't seem to build with the current SDK.  I changed the return value of CyU3PDmaBufferFree as described in the porting guide, and that gets me as far as linking.  That fails with a number of undefined references:

./cyfxbulksrcsink.o: In function `CyFxBulkSrcSinkApplnDebugInit':
C:\Users\user\Workspace\cyfx3ad9269\Debug/../cyfxbulksrcsink.c:102: undefined reference to `CyU3PUartInit'

C:\Users\user\Workspace\cyfx3ad9269\Debug/../cyfxspi_bb.c:49: undefined reference to `CyU3PGpioSetValue'

I'm not too familiar with the SDK yet.  Could someone point me in the right direction for getting this building on a modern SDK version?

Hi everyone,

I want to configure the DS-1 port of CY611 EZ-USB HX3PD EVK to supply 12V. But when I try to configure  using EZ-USB HX3PD configuration Utility - PD Controller- Port 1, it shows me error - Atleast one 5V PDO should be enabled in Source PDO. But if add another source PDO of 5V, it does not save the configuration.

Can anyone help please ?

Thanks

I've been experimenting with the PSOC 6 BLE Pioneer kit to come up to speed on Cypress parts and the PSOC Creator IDE. I read that the chip has a floating point unit, and I was searching through the options in the IDE to see how to enable floating point operations in hardware (but didn't find anything). I searched the forum and came across a post from a few years ago that outlined a manual process for setting the compiler flags and linking the libraries, but it seemed somewhat involved and not user friendly. I wanted to know if this issue has been addressed in the latest version of PSOC creator 4.4, and if so, how do I access it? If it hasn't been addressed, I would assume that enabling the FPU is discouraged for some reason. Are there library compatibility issues I should be aware of? In a worst-case scenario, are there intrinsic functions available to access the FPU instructions?

你好！我已经安装了ModusToolbox V2.2。当我通过File--->New--->ModusToolbox Application后，可以弹出Project Creator 1.2-Choose Board Support Pcakage(BSP)的对话框，但是Kit Name栏里全是空白，下面有提示“Checking if remote manifest is accessible...

I have a system that uses BLE for communication. It is supposed to be BLE 4.2, but I cannot get it to send packets with more than 22 bytes (0x16). The packet data is truncated at 22 bytes.

I am using the Cypress BLE Dongle as a replacement for the system master, which will eventually be a phone-thingy.

Dongle: CY8C5868L

Device: CYBLE-222014-01

These are the BLE setup screens for the Dongle. It is using BLE object 6.5. The BLE setup screens for the device are the same.

This is a typical transaction that is supposed to be  28 bytes of data. It is truncated to 22 bytes (0x16).

Packet capture is with the TI RF-Sniffer, which is nominally a BLE 4.0 tool. But note that the data packet arrives with a 'length' of 0x17 - 1 byte of ATT op code + 22 bytes of data.

Is there something else I need to do to get longer packets?

代替候補品についてご確認したい点がある為、ご回答をお願い致します。

製造中止品：S29GL032N90TFI010　32Mbit

代替候補品： S29GL128S90TFI010　128Mbit

１．製造中止品に対し、代替替候補品はメモリ容量が増える為、アドレス線が2本多くなります。

　　（2pin：A21、15pin：A22が増えます。製造中止品は共にN.C。）

代替候補品のアドレスピン：A21、A22は未接続のままとすることで

32Mbit品として使用する事は可能でしょうか。

デバイス内部にプルアップ等、信号レベルを固定する回路は有るでしょうか。

２．また、使用コマンドについては互換性が有ると考えて良いでしょうか。
