Hi,

When using CSX, the Cint caps have their return path to analog ground (VSSA). If I am using CSX and CSD widgets simultaneously, can I join the return paths for Cmod and Cints like this :

And a single trace connects this nod to analog ground (VSSA)

OR

is it better to split signals and have a trace to VSSA for Cmod separate from a second trace to VSSA for Cints:

Thank you!

Hello,

There is a data rate range recommended by the I2C master,

Can the I2C master select a data rate in the range of 0-100 kbps when the I2C slave setting is in Standard-mode and 0-400 kbps when it is in Fast-mode?

Best regards,

Hi,

In a PsoC4 project attached below we demonstrate a PWM compare register write bug.

It appears like if reg is written by the CPU at the same time as TC occurs pwm output is forced high for the entire period, and within the next cycle the latest compare value is in effect.

We have tried combinations with RegSwap, which also appears buggy, at certain occasions it swapped immediately.

Looking forward to hearing you and your explanation and best work-around.

Kind regards,
Uros

Hi Sirs,

Customer use CY8CKIT147 the I2C Master to test Capsesnse(CapsenseMTKTool) ,But the driver can't support WIN7 ,Is there a driver that him to support  WIN7?

Thanks,

I've been working on this for a week, learned some, so let me restate my case. I'm using brand new, US big-name distributor, sealed CYBLE-012011-00 modules on two different perfboarded prototypes of different layouts.

I can program them with the downloaded hex file of EZ-Serial and they behave properly, visible under any OS, pair instantly. I have tried three different examples (only modified for switch/LED pin assignments) BLE_HID_Keyboard, BLE_HID_Mouse, BLE_Heart_Monitor. All of them program and verify correctly. All of them only pair with difficulty (hitting pair 50 times). All of the HID examples are not even visible under Windows. On the occasions that I have got the Keyboard to pair with Android it has worked functionally correct, but balky, with latency problems and the connection dropping. The power is good (batteries, different power supplies) and the layout keeps out of the antenna area. The distance is two feet.

What is going on? Could somebody post a hex file (with BLE) for the CYBLE-012011-00 so I can have a reality check? I'm running on the 3.66 BLE version, although I have tried 3.50 also. When I have added user parts to the code those parts have operated correctly within the constraints of the BLE part flakey.
