PSoC™ 4 Forum Discussions

Hello Support Community,

I am new to PSOC4. I am working on a scenario where there are multiple of cyble 224116-01 modules advertising themselves at the programmed advertisement intervals. All devices are able to pick up those advertisements and the device IDs are been displayed on a serial output (PuTTy monitor). What we want to do is log that kind of data into a SD card. My question is what will be the process to interface an SD card with Cyble 224116-01 module. I do have a SPI based SD Card Adapter available but I'm not sure how to configure the pins for the above purpose.

Hoping for immediate help.

HELLO ALL,

I am looking for a low cost PSOC device to be a "power good"device.. containing one of the power monitor modules in PSOC creator.

Might be PSOC 4.

thanks

Hi guys,

I am using the CY8C4125LQI-S432 in my project (PSoC4100s).

From what I read from the datasheet, I found that the smallest operation in flash is a row, which is 256 bytes in size.

If I use the last row (which is 7F00 to 8000) for the self flash, I will have to erase the whole row and re-write the whole row every time the system needs to save settings.

If I reserve more rows for self-flash (so that I can write to 7E00 first time, 7F00 second time...etc), the expected flash life cycle will be extended.

But my flash size is only 32KB, I don't think I will have that much flash space left after programming.

So I am wondering, is there a smaller size operation for the flash?  or is it a limitation that it must be written and eased in 256 bytes?

Thanks guys

Hi,

I'm working on a project where I need to interface a 4200 device to a number of external 5V signals. The problem I'm having is that when I remove the main power from VDD, if the external signals are alive (all are high when idle) that voltage on the external pins filters through the GPIO circuitry and is enough to maintain the device powered. Is there a way to prevent this, or am I forced to use opto isolators for all the I/O (including a couple of serial ports). That alternative will increase the cost, complexity, and size of the final product.

HI,

I am designing a capacitive touch keyboard using a PSOC4 4200L, the design requires using spring coupling to the overlay.

As this design will be used outdoors we also need liquid tolerance, what is the best practice for the Guard electrode and shield electrode in this instance, do they need to be coupled to the overlay?

Thanks in advance

Hi there,

this is my 2nd discussion and as I asked a bit too unprecisely in my 1st one, I want to make it better now.

I am trying to implement a lux sensor on my psoc 4 ble kit but I just don't understand how to implement the services and how to start the main.c program.

At the moment I am trying to understand the API's for the BLE module but some are just unclear and not really documented in the documents where they should be.

So can some please give some advice and help on my way to get this thing done.

I am currently putting 6-7 hours a day into this project but without help I am lost.

Thanks

Chris

Hi,

Can I get a simple firmware (without UART or button) for testing FCC for allowing the following changes to BLE? We are using CY8C4248LQI-BL583 with customized PCB.

• Frequency channels (low/mid/high)
• Highest Modulation

Thanks

I am programming  external programmer with CY8C4248lqi_bl583.

According to AN84858, after I call SetIMO48Mhz(), I receive the system call status code 0xF0000013.

What does it mean this code?

Cypress document doesn't explain this code.

Thanks

Justin

Hellow,

The following SWD interface is used to use the debugging function of CY8C4024LQI-S411.

SWDCK (P3_3 pin)

SWDIO (P3_2 pin)

XRES

Q1.

Could you provide me with the recommended pin processing information for these debug pins?

*

For example, the following information:

1)The pull-up resistors of SWDIO and SWDCK must be in the range of 1 k to 100 k ohms

2)XRES does not require pull-up processing

Best regards,

Harukawa
