PSoC™ 4 Forum Discussions

Does anyone know if there is planned development for the PSoC4 CY8C4A Analog Coprocessor? Is it safe to assume that it will continue to be supported for the coming years? The CY8CKIT-048 development board for this chip is getting hard to find and is labeled as "End of Life", so I'm getting a little worried that starting a new project with this chip could be risky. If we could get assurance that this chip will continue to be supported for the coming years, it would really help.  Thanks!

Hi!

Do you have a datasheet for the CY8C4045FNI-DS400T ?  This 20-WLCSP part is not mention in the datasheets.

In PSoC Creator it also has fixed VCONN1, VCONN2, RD1, CC1 and RD1 pins.  See attached pic.

What are those pins for?

I have a feeling it may be an undocumented PD part similar to the EZ-PD / CCG2.

Both Mouser and Digi-Key stock CY8C4045FNI-DS400T.

Thanks!

Hi,

i'm using a CY8CKIT-149 eval board and PSoC4 and i would like to measere internal temperature using a DieTemp component. How do i have to configure the ADC SAR Seq component for measuring the temperature given me by the DieTemp comp? Is there some example code for using it?

Hello,

I have implemented the CY8C4147AXI-S455 on a board and use the I2C bus on pin 18,19 as a master. This master sends only command to a slave implemented on an Arduino mega board.  No read access are performed.  

The clock is 100kHz.  Pull-up resistors are 4,75k. Both boards are supplied with a common +5V. 

As long as I tested I2C messages  sent by the master without slave connexion I could see  proper signals on data and clock.  Of course NACK was detected. 

When I connect the arduino board, then no signal are detected : SCL is  forced to 0 and SDA forced to 1.  No clock and data activity. 

Then when I disconnect the arduino board, SCL remains permanently low and SDA high.  The bus does not work anymore.

Is the bus definitely out of order?  What happened? 

Hello
I am using CY8C4245AXI-483. I want to test SRAM using Safety Library AN89056 .
It is working fine but I have a confusion. As SRAM base address is 0x20000000. And CY8C4245AXI-483 has 4 kB SRAM.
While debugging the microcontroller, It tests only up to 0x20000B00. So, It is only testing up to 2816 bytes. and theoretically, it should test SRAM till 4096 Bytes. Kindly guide me where I am making mistakes or suggest me the correct parameters to select to Test full SRAM.

I am considering using the PSOC 4000 in a design, but cannot seem to find the pinout for the WLCSP-35 package.  The datasheet that is associated with this package (on Mouser.com, for example) only shows a pinoout for the WLCSP-25 package.

Does anyone know where I can find a data sheet that shows the PSOC 4000S WLCSP-35 pinout?

Thanks,

Bob

hallo, I am trying the PSoC 4 Voltage ADC using CSD Hardware (CSD ADC)
1.0, but the result of my readers are only FFFFFF, somethings is wrong?

Thanks

Hi,

i use the CY8CKIT-043 with a Psco 4200M. I built the example project CE195366_PSoc4_SCB_UART.

1. When i connect the board with the USB port of the pc the first time, i don't get a output of the UART_UartPutString() function in the termial program. I have to press "Enter" -> CR that the program works.

2. But when the board is connected with the pc before and I program the board again, i get a output in the termial and the UART_UartPutString() function works fine.

3. When i code a function that preforms a SoftReset -> CySoftwareReset() i have got the same behavior like in setting 2 -> So it works

For the UART i use pins P7[0] and P7[1] -> USB-UART Bridge of the KitProg

What's wrong in setting 1...??

Here is the code:

#include <project.h>

int main()
{
uint32 ch;

/* Start SCB (UART mode) operation */
UART_Start();

UART_UartPutString("\r\n***********************************************************************************\r\n");
UART_UartPutString("Welcome to the CE95366 example project\r\n");
UART_UartPutString("If you are able to read this text the terminal connection is configured correctly.\r\n");
UART_UartPutString("Start typing characters to see an echo in the terminal.\r\n");
UART_UartPutString("\r\n");

for (;;)
{
/* Get received character or zero if nothing has been received yet */
ch = UART_UartGetChar();

if (0u != ch)
{
/* Transmit the data through UART.
* This functions is blocking and waits until there is a place in
* the buffer.
*/
UART_UartPutChar(ch);
}
}
}

I used CY8C4045LQI-S411 to do the CSX MATRIXBUTTONS experiment. I need to send the capsense status of the touch to the host for judgment, so which function do I need to use to obtain the state of the key and whether there is a routine for reference,thanks！
