Hi all,

We are facing one issue of hanging touch panel.

When capsense is not working, other ISR is working.

How can I detect a fault in cap sense ?

How to get an error code in this situation?

How to solve this issue ?

Should I use the api "CapSense_Stop()"  before  "CySysPmDeepSleep();" and after WDT wakeup use  "CapSense_Start()"?

If I don't use these two api ,    CapSense_NOT_BUSY == CapSense_IsBusy()  can't  pass. When I use the api  "CapSense_Start()"  ,the current increase 200 ua.

Hello, 
I want to use the AN89056 Ram test in my project. I have copied all the required files from the AN89056_Ram test in my custom project. I have also compared the build settings of Project AN89056 Ram-test and make them equal but it is giving an error. 

--undefined reference to MArch_Test_init

--undefined reference to MArch_Test_SRAM

this function is in "CyLib.h" and in assembly but the project does not find a reference. Could you please help me regarding????

Hello Team,

Kindly let us know if CY8CKIT-042-BLE kit supports simultaneous multi keypress functionality.  If yes you can share an example code with us.

We have a requirement wherein we have to press two keys (e.g. Menu up + Power on/off) simultaneously for 10 seconds to pair kit with the BT Device.  

We have seen BLE HID keyboard example but it sends only one key at a time.

Has anyone had any luck implementing Zlib compression on a PSoC board? I'm looking to use this method to transfer a large amount of data sent via BLE. 

Are there any Cypress libraries out there to easily perform this sort of operation? 

Hello, I am new to PSOC, and is currently working in CY8C4245AXI-483

I am trying to make a simple project to read and write the data in external eeprom using i2c, untill now i have aquired the result but the data i stored is in "HEX" whereas the data i received on my serial is in ascii

EX: I am sending (0x42, 0x43, 0x44, 0x45, 0x46, 0x47, 0x48, 0x49)

and receiving "B C D E F G H I

Why do i not get HEX in output and how to get it ???

My code is given below

#include <project.h>
void main()
{
uint16 read_val[8]; //Array to read data from EEprom
uint8 array[8] = {0x42, 0x43, 0x44, 0x45, 0x46, 0x47, 0x48, 0x49}; //Array to write data to EEPROM
uint8 i;
uint32 status; //variable to read error/status of I2C

I2C_Start();
UART_Start();

for(;;)
{

status = I2C_I2CMasterSendStart(0x50, I2C_I2C_WRITE_XFER_MODE); //Send start with slaveID 80u & write/read transfer mode

if(I2C_I2C_MSTR_NO_ERROR == status) //Check status
{
status = I2C_I2CMasterWriteByte(0x00); //address of eeprom on which data needs to be written

if(I2C_I2C_MSTR_NO_ERROR == status) //Check status
{ //if valid write data to external eeprom

for(i=0; i<8; i++)
{

status = I2C_I2CMasterWriteByte(array[i]);

if(I2C_I2C_MSTR_NO_ERROR != status) //Check status
{ //if success come out of loop

break;
}
}
}
else
{
UART_PutString("error"); //else print error
}
}
I2C_I2CMasterSendStop(); //Send stop

/***************Read that same data from external EEPROM**************************/
CyDelay(500u);
status = I2C_I2CMasterSendStart(80u, I2C_I2C_WRITE_XFER_MODE); //Again send start
if(I2C_I2C_MSTR_NO_ERROR == status) //Check status
{
status = I2C_I2CMasterWriteByte(0x00); //address of eeprom to read data on it
if(I2C_I2C_MSTR_NO_ERROR == status) //Check status
{
CyDelay(50u);
status = I2C_I2CMasterSendRestart(80u, I2C_I2C_READ_XFER_MODE); //Send restart
if(I2C_I2C_MSTR_NO_ERROR == status) //Check status if no error
{
for(i=0; i<8; i++)
{
if(i<7u)
{
read_val[i] = I2C_I2CMasterReadByte(I2C_I2C_ACK_DATA); //receive data bytes with ack


}
else
{
read_val[i] = I2C_I2CMasterReadByte(I2C_I2C_NAK_DATA); //receive last byte with nack

}
}
}
}
}
I2C_I2CMasterSendStop(); //Send stop

for(i=0; i<8; i++)
{

UART_PutChar(read_val[i],); //display data on uart
UART_PutString(" ");
CyDelay(500u);
}

CyDelay(3000u);
}
}

Hi, I am starting out from scratch and I am trying to figure out what I need to get started.

I have been proposed the:

CY8CKIT-046 PSoC 4 L Series development board.

I don't really know how to get started with this? Where do I download the compiler software "Psoc Creator"??? Is there any simple examples like blink a led to get me started????

Also I am reading the "Infineon Lit Prog" user guide". On page 8 of the guide (please view image below), they show an image with what seems to be a PCB board plugged into a strange socket on a PC.

And yet they describe this as "Connect USB cable to J6 (Prototyping kits)"???? Why do they call it a cable when its a PCB???? and where is J6???

Thank you for all help

Hi,

We are trying to execute an application by using your “CY8C4014LQI-24-QFN“ processor. However we have an problem on programming this chip.

When we make a short search we can find in your site(https://www.cypress.com/products/psoc-programming-solutions) that can be done by using MiniProg4 and MiniProg3. In addition to this devices we also figured out that the programmer part of “CY8CKIT-147 PSoC® 4100PS Prototyping Kit” can also have ability to programme any kind of Cypress processor. But we could not achieved for programming our chip. So i have below question about this situation.

1-) Are MiniProg3-4 devices the only solutions to programme “CY8C4014LQI-24-QFN“ processor or like we found in internet this can be made by using programmer part of “CY8CKIT-147 PSoC® 4100PS Prototyping Kit” having “CY8C5868LTI-LP039” processor for controlling programming jobs.

Hello,

I am trying to use the psoc 4 mcu as a timer that switches a GPIO between high (20 minutes) and low (10 minutes) states. I want the mcu to be in deepsleep most of the time and just toggle the GPIO every 20 / 10 minutes.

How can I do this and is there some sample code to refer to?

Thanks
