I am using the ADC_SingleEndedMode Example.

#define USBFS_DEVICE    (0u)

#define USBUART_BUFFER_SIZE (64u)

#define LINE_STR_LENGTH     (20u)

int main()

{

    int16 output;

    uint8 buffer[USBUART_BUFFER_SIZE];

    /* Start the components */

    CyGlobalIntEnable;

    LCD_Start();

    USBUART_Start(USBFS_DEVICE, USBUART_3V_OPERATION);

    ADC_DelSig_1_Start();

    /* Start the ADC conversion */

    ADC_DelSig_1_StartConvert();

    /* Display the value of ADC output on LCD */

    LCD_Position(0u, 0u);

    LCD_PrintString("ADC_Output");

    for(;;)

    {

        if(ADC_DelSig_1_IsEndConversion(ADC_DelSig_1_RETURN_STATUS))

        {

            output = ADC_DelSig_1_GetResult16();

            /* Saturate ADC result to positive numbers. */

            if(output < 0)

            {

                output = 0;

            }

            USBUART_PutChar(output);

            LCD_Position(1u, 0u);

            LCD_PrintInt16(output);

        }

    }

}

I am using CY8C3866LTI-068.

Even though , Pin no 7,8 and 10 are multi function (GPIO), I am not able to rout it in PSoC for GPIO.

Can I use pin no 7,8,10 for programming / debug only ? 

Hello,

I want to create a switchable level at an OR gate and switch it via API low -> high -> low ....
Which components are required? There are logic levels low and high, but these are constant and can not be switched via API.

thank you for your help in advance

We are considering UART Bootloader with reference to AN 68272.

However, the time required for writing is long.

Therefore, I set the baud rate to 57600, but it still takes 8 minutes.

I confirmed the source code to speed up.

On line 199 in UART_BOOT.c,
"CyDelay (UART_BYTE 2 BYTE_TIME_OUT);" has a waiting time of 25 ms written.

We tried writing with this setting at 2 ms.
With this change, the writing that took 8 minutes has been shortened to about 50 seconds.
It is working without error.

Please confirm that this change is not a problem.

And do you have any material that understands why this is set to 25 ms?

Hi,

I want to realize a small audio application, which should have an audio output and alternatively be able to work as an USB audio input. Two questions:

1) For the audio output, I assume that the line-in voltage of a audio device is typically about 0.775V. Is this correct? So, if I'm using an IDAC with 2mA setting and a 380 Ohm resistor, I'll get about 0.76V. Using an OpAmp in FollowerMode to achieve high current output, I can connect the PSoC5LP directly to a line-in input or drive a headphone with at least 32 Ohm impedance (0.76V divided by 25mA OpAmp output current results in ~30 Ohm) without damaging the device?

2) Anyone has experience with setting up an USB component for USB Audio input? It seems that there's a template for audio input application for the USB decriptors, but I don't know if I can use it directly without modification. Unfortunately there's no example firmware for USB input, only an output example is provided.

Regards

hello I am currently using the sparkfun 2 , and in my project i am using ADC is it posibbile to see the resolt of the adc on the computer screen and not only on external LCD screen (for exmpale in arduino to see the resolt on the cumputer you press serial command ) is there a comnd similar to the Serial like in Arduino but in Cypress ?

Would there happen to be any STEP models for the following components?

1. CY8C5667LTI-LP009

2. CY8C5868AXI-LP032
