PSoC™ 4 Forum Discussions

I have been searching around and can't seem to find the Cypress recommended footprint for the WLCSP-25 (Package Drawing #002-09957) package. If needed, the footprint is used by the following PSOC4 devices that I am interested in - CY8C4024FNI-S402, CY8C4024FNI-S412, CY8C4025FNI-S402, and CY8C4025FNI-S412.

Hello.

I want to communicate to other device by using PSoC I2C component but I dont know how to use.

I want to put PSoC as master and the device as slave and just want to write.

Could anyone give me some easy sample code to use I2C??

Hi,

I'm using Kitprog2 which took from CY8CKIT-149 to program the CY8C4127AZI-S453 which is on the board we designed.

The PSoC programmer can connect to Kitprog2:

Successfully Connected to KitProg2 (CMSIS-DAP/244532) at 11:01:00 | CMSIS-DAP Version 1.10

But when I try to program, it notice me the following:

Programming Terminated

Detected SiliconID: 25 94 12 B5 is not in database

Error paring device information from database

PSoC Device (25 94 12 B5) is not in the DataBase

Does it mean Kitprog2 can't support CY8C4127AZI-S453? Any change needed for this programming? Thanks

Is there an example to reserve an area of PSoC 4 Flash during debug and re-programming?

This question is about user flash and debugging.

When debugging code, the IDE reprograms not only the code, but the entire flash, erasing any user information stored there.

#define CY_DATABASE_START_FLASH_ROW (CY_FLASH_NUMBER_ROWS - 2u)    

Some concepts that are similar; but lacking examples include:

Hello,

We are facing strange trouble on the third revision of our boards.

Below are the observations:

1. Able to correctly flash CY8C4248LQI-BL583 every time.

2. I am setting baud rate for UART to 115200 in firmware and in reality, the baud rate is 96318(83% of expected).

3. Same is the case with I2C Master Clock is also 83% of expected.

4. I used CyDelay(100). And the actual delay is more than 100ms.

5. Earlier I suspected trouble with Crystal. I probed XTALO and XTALI. They seem fine with a sine wave of 24Mhz(Attached scope capture).

6. The device also reset after running for some time(3-4 seconds).

7. BLE is not at all functional.

8. Verified voltages on VDDA, VDDD and VDDR. They are stable.

The PCB revision doesn't seem to change much. The circuit is same just minor layout changes in component placement.

How to debug this issue?

Hello,

There is the device initialization time from reset to te main() entry.

Please see the "PSoC 4 System Reference Guide cy_boot Component v5.80" on 84 page.

We don't have to care for this time right?

Best regards,

Hello,

This is regarding the I2C project that I have posted a few weeks before. I am currently working on designing a prototype board with the PSoC 4 MCU to establish the I2C interface with the video decoder to write to the registers on power-up. So I thought of checking whether Cypress has the option of preprogramming the chips with my I2C code if I request for it while I purchase the chips from Cypress website online. 

If it's not possible to buy the chips after programming it is there any programmer kit that has a header for the PSoC 4 BGA chip-WLCSP package (CY8C4014FNI-421AT) to plug onto the programmer kit for preprogramming the chip before sending out the chips to be soldered onto a target PCB.

It will be great if someone could advise me regarding this concern.

Thanks and Regards,

Dear  Cypress:

        when i start to learn about the  CYBLE-212020-01 module , how can i send one date form one module and  received form another module;

can you provide the code example for us ?   For the API command ,can you provide the describle file for total , tks;

Trying to communicate with a PSoC4200BLE of the type CY8C4248LQI-BL593.

Mounted it on a breakout board and trying to program it for the first time through a CY8CKIT/146 P|SoC 4200DS prototyping kit, by using PSoC Programmer and Creator

We have tried by HSSP but we had problems, are there other ways to communicate with the PSoc4BLE?

Any suggestions about how to proceed?

Any specific documentation, step by step guide or similar problem?
