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

请问Hex File中的下面红色加粗的内容代表的是什么？

程序升级成功之后其中AB00会变成AB11，这样会有问题吗？

Hello 

I have a hw design where i use a CYBLE-222014 and some  PWM controlled LED's.

My problem is that one of my LEDS is hw wired to pin 4.0, which is not routeble from PsoC Creater.

How can i from code make it posible to adjust PWM on PIN  4.0 ? 

Hello,

Our company is looking to move forward with Bluetooth SIG testing and we require the QDID numbers for the CY8C4248LQI-BL573 microcontroller. I've checked the datasheet and a few application notes and have not found this information. Can someone help?

For the stack QDID, where in the Cypress software libraries can we find this information?

Thanks!

hey! Community.

I'm facing one issue while programming CY8CKIT-145-40xxS PSoC  DevKit. I ordered CY8CKIT-145-40xxS PSoC now I'm playing with that kit I started following the User guide of that Kit. 

I performed these steps 

1) Download and installed PSoC 4 IDE

2) install Kit package from here

3) create a new blank project 

4) Select kit as shown below 

5) Compile/build project 

6) insert kit to the USB port of the laptop

7) Select the programmer  

8 )  Acquire the port 

and that point I'm getting this error.

I'm waiting for few seconds and got this message pop-up.

Thank you 🙂
