Hi I''m trying to read the value of a GPIO pin on the Cy8CKit-040 PSoc4 4000 Pioneer Kit). I want to read this value in Debug mode, and see how the value changes accordingly. For some reason, I cannot create a Watch expression for the variable that I am trying to observe.

Attached is my main.c file.

Analog_In_Read is the name of the Analog Pin I want to read. I have set this pin to be P0_0 on the MCU.

Thank you for your time

Is there any one who can help me to interface KY-039 fingertip heart rate monitor sensor with CY8CKIT-042. I tried it but I am not able to complete it.

I want to write an app to replace cysmart to implement ble upgrade, but do not know the specific bluetooth protocol, can someone provide some relevant documents?

Hi team,

Iam trying to set one 4200 BLE CPU at Stop Low Power Mode. The snippet of code to do this is the following

inline void GotoStop()

{

    CySysPmSetWakeupPolarity(CY_PM_STOP_WAKEUP_ACTIVE_LOW); 

    printf("\r\nSLEEP\r\n");

    CyDelay(1000);

    UART_Stop();

    CySysPmStop();

}

but unfortunately nothing happens. The power consumption remains the same.

The strange thing is that if I changed the first code line from CySysPmSetWakeupPolarity(CY_PM_STOP_WAKEUP_ACTIVE_LOW);   to CySysPmSetWakeupPolarity(CY_PM_STOP_WAKEUP_ACTIVE_HIGH);   the CPU goes at Stop mode and the power consumption is almost zero.

But as far as my hardware asks for falling edge at pin P0.7 for wake up, the CPU remains at Stop Low Power Mode forever.

Any idea, or suggestion?

Thanks

Bill

Hi,

We are using CYBLE-012012-10 Module for our Project and interfaced Sensor through UART.  We need to set Beak out On Uart. Kindly Suggest us how to setup breakout and hold for 50ms.

Thanks and Regards,

While i compile the program on main.c

their have a message that "Error dbg.0023 There was an error while programming the device: failed to reacquire the device"

So how can i fixed it? t

PS. the message box tell that we should config the port. But i don't know how to config it thanks.

Hello everyone,

I am trying to locate the source code for BLE-Beacon IOS app. Has anyone worked with it?

Thanks,
