PSoC™ 5, 3 & 1 Forum Discussions

I'm trying to have a PSOC5LP emulate a PS4 controller which has two INT endpoints (IN/OUT).
The IN is working (HID data successfully transfers) but the host device driver doesn't seem to see the OUT endpoint.
I've been using Wireshark (USBPcap) to compare a real PS4 controller vs using the PSOC5LP.

Endpoint config:

After enumeration:

The Code:

uint8 data_buffer[250];
uint16 length = 0;

int main(void)
{
    CyGlobalIntEnable; /* Enable global interrupts. */
    UART_1_Start();
    USBFS_1_Start(0u, USBFS_1_5V_OPERATION);
    while(!USBFS_1_GetConfiguration()); // Wait until USB is configured
    USBFS_1_EnableOutEP(3); // Enable output endpoint
    USBFS_1_LoadInEP(4, HID_data, 64); // prime the USB buffer with usable data
    Clock_1_Start();
    isr_1_StartEx(Scan_Devices);
    
    
    data_buffer[0] = 0;
    for(;;)
    {
       // send data out to PC
        if(USBFS_1_bGetEPAckState(4))      // wait for ack from PC
        {
            USBFS_1_LoadInEP(4, HID_data, 64); // send HID data to PC
            // increment report count
            report_count += 1;
            if(report_count == 0x40) report_count = 0;
            HID_data[7] = report_count << 2;
        }
  
        if(USBFS_1_GetEPState(3) ==  USBFS_1_OUT_BUFFER_FULL) 
        {
            length =  USBFS_1_GetEPCount(3); // Get the length of received data
            USBFS_1_ReadOutEP(3, data_buffer, length); // Get the data
        }
        
    }

Hello everybody,

does one of you know if I can use the Micro-USB on my CY8CKIT-059 while supplying it externally with 3.3V? I have heard about removing D2 to split up VTARG and VBUS to not shorten the supplies. Though I am afraid that the logic levels of DM and DP could still be a problem due to the USB-connector working with 5V and the controller with 3.3V. 

In the user guide of  CY8CKIT-059 in the section about the power supply system, only using the PCB-USB gets mentioned while being supplied externally. In this case it says that KitProg adjusts the logic levels accordingly. Does the CY8Y5888LTI-LP097 adjust the logic levels in my case aswell?

Thanks a lot in advance,

Tim

Hello!!

I have a PsoC 5 project in which I use an ADC_SAR component.
Is it possible to modify the reference voltage value via software? I need it to be able to take two different values
Thanks in advance

Hi,

I have a question (and I suspect the answer is yes) regarding the GPIO ports on the PSoC5LP.

I have a few serial (9600 Baud) signals passing through the PSoC that could potentially require re-routing through the PSoC onto different voltage domains.  On one end the device is 3.3V and the other is 1.8V.

Will this all just "work" presuming I have the VDDIO levels for their pins set appropriately and level shift the signals between the inputs/outputs?  Or should I perform level shifting externally?

Thanks!

Hello Community,

I am trying to implement a control functionality for the LCD backlight in my application, where the backlight of the LCD needs to be switched OFF after an interval (~10sec) maybe using an interrupt, without affecting the program's execution.

The system consists of a PSOC5 LP, 16x2 LCD, a temperature sensor over ADC, and a pushbutton (or a 4x4 keypad - I know the method of detecting the keypress is different), which can act as a trigger.

I think the approach is to use the timer, and trigger it with a pushbutton (or 4x4 Keypad - preferred) to generate an interrupt after a period has elapsed and then turn off the LCD backlight, without halting the execution of the program completely (like printing the temperature value continuously even after backlight is OFF), which I think would be to use the One-Shot mode of the timer. 

Using the One-Shot does help with triggering and turning the LCD backlight OFF only once, but no response after that. The main application is a MENU system, where the LCD would need to go OFF on different screens, so the timer needs to have a reset of the Period once the ISR is finished - to then be able to trigger again and so on.

I would like to get some help with this application and I am unable to comprehend on how to reset the timer for the above-mentioned application.

Attached is the firmware with One-Shot Timer and ADC.

Hope someone can help.

Yash

I installed PSoc 4.4 from the provided CD, onto my CY8CKIT-050 KIT.

It recognizes the device when it is plugged into the programming USB, but when I plug it into the communication USB I get the device descriptor request failed.  I tried updating drivers, but I am not sure which ones are needed.  Any information on how to get it to read would be appreciated.
