PSoC™ 4

Hello,

I am working with PSoC-4 and want to know what is the PSoC-4 boot time. How much time it take for executing the first line of main() upon power-up. I could not find this data from Cypress website. 

Please help.

Thanks,

Hello,

I have psoc 4100s plus. And I want to communicate with SHT20 temperature and humidity sensor and read the data. But I could not. I could not find the correct communication and reading addresses. Can you help me ?

I share the images of the products here.

Thank you.

Best regards,

Hello,

We know how to get the touch position(centroid) of CapSense Linear Slider with PSoC Creator.

       uint32 centroid;

      centroid = CapSense_GetCentroidPos(CapSense_SLD_WDGT_ID);

How can we get it with ModusToolbox?

Best regards,

Hello Folks!

I am using CY8C4124LQA-S433 IC and I did a project which has following specification: 
When I press the button related led on. Then when I press one again, related led turn off. So far everything is fine. I did this. 

But the problem begins with : "I do not want that Led toggle to on or off when I falsely touch a button."

However I could not  achive this. I tried everyting. I rised threshold values, I tried smartsense option. I could not do this. When I touch a button outside of my hand for only half of the second, led could not hold its last mode. 

I just want the led to change mode when I press the button hard.

Any solution, any idea to get more strong project?

Regards,

Mehmet

Hello,

My project is very simple. Is one button is pressed, related led on. If the button pressed again, led off. however I could not prevent the false touch. I do not want to led on or off when I falsely touch a button.

I have an idea which is following;

if  a sensor active, related sensor flag would set. if time between the flags is more than 500 ms, do your job. If lesser than 500 ms, do not do any thing.

How I can put my code to this idea? could you please give an example code because you have my project.

Regards

Hello everybody,

Hardware: PSoC 4 Pioneer Kit 042

2x TLE493D 3D Hallsensors 

The problem is that after I flash or reset the board, the sensors are sometimes (almost every second reset) not initialized correctly.
After the reset I get a normal communication or only the first sensor is initialized and the second one gets stuck and there are only interrupts on the SDC line.

Although I only have a delay of 150 µs between the initialization of the first and second sensor in my source code, I measure a delay after the reset of the board of 60 ms as shown in the picture.

The reset() function resets both sensors by sending 0xFF twice and 0x00 twice with a delay of 30 µs to the I2C bus as described in the User Manual.

After that I initialize the sensor one with the address 0x22 and then the Vcc of the second sensor power up and init the second sensor with the address 0x35

// ---------------------------------------------------------
    /*********************************************************
    * Configuration and initialization of the TLE493D sensor
    ********************************************************/
    reset();
        // Power Off / Power On the TLE493D
    VDD_sensor_Write(0);
        
    TLE493D_Init(TLE493D_AW2B6_I2C_A1_ADDR);
    VDD_sensor_Write(1);
    CyDelayUs(150); // Small Delay
    TLE493D_Init(TLE493D_AW2B6_I2C_A0_ADDR);
    UART_PutString(" Beginne mit der Kalibrierung  ");
    UART_PutCRLF();
    CyDelay(100);

Why does this error happen and where does the 60 ms delay come from?

Hi,

i want to receive data on Raspberry Pi via UART from Cypress. Here's what I did. I connect RPi to power supply, then:

• pluged keyboard and mouse to RPi,
• run lsusb on terminal - I saw a mouse and keyboard detected,
• run ls /dev/tty* - I saw a list of UART devices (including keyboard and mouse),
• pluged cypress to RPi (via USB),
• run lsusb on terminal - I saw a mouse, keyboard and cypress detected,
• run ls /dev/tty* - nothing changed to the previous log (do not detect the cypress).

What can be wrong? Maybe I need to change some config file or sth else?
