Hello There, I was looking for alternatives for DZ600N12K/DZ600N14K as both of them were EOL and it is tough to procure any of them in the market. Could you recommend any replacement for these?

Thanks in advance.

Hi, I'm using CYT4BF.

I confirmed that the Bandgap Reference circuits can be set to higher current mode or low power in the PWR_CTL2.BGREF_LPMODE register.

1) Can you explain in more detail the higher current mode and low power mode of Bandgap Reference circuits?
2) Can you tell me in what cases the PWR_CTL2.BGREF_LPMODE register is used?

BR.

Hi!

I've grown an inherited mess into a now now-useful application running on PSOC 5LP (CY8C5868AXU-035), using PSOC Creator 4.4.

We burn our board FW using  KitProg 'dongles' connected to the SWD port + PSocProgrammer v3.29.5 - so far so good.

But we will need to make this a UART bootloaded app, with UART bootloader, for the 'real world'. 
 
    [info: currently..  C code: ~49K flash/13K RAM; 
                                        296K .cyfit file / 7.5K  config.hex
                                        650K project hex file;
                                        future: RAM use will decrease a bit, C flash code will grow maybe 5-10 K]

1.   I have documents on bootload and broad understanding,  but where is link to ZIP file sources? 
       Found some old dead Cypress links, or links to irrelevant PSOC4 or 6 platforms...  
       Do please direct me to current valid PSOC5  code working on PSOC Creator 4.4  so I can begin to
       play with it without pulling my hair using wrong/stale stuff, errors etc.

2.   Where is the downloadable PC host app?   Ideally I would like some command line C code to
       download/burn .HEX file - small possibility exists this code might be wrangled onto an Android
       platform some future time.   

3.  Approx expected time from FW burn thru reset into acutal app (not counting 2 sec delay) for a
      650K Hex project file @ 115Kbps-8N1 serial rate? 


At first glance it seems easiest to me to use exactly the same "soft hardware" from our FW app to build the
bootloader  (which has fixed 115Kbps UART used for logging/configuration etc.)   so that there is no "discontinuity" between the entities  (other than "bootload" vs "bootloadable" distinction).

Any other guidance/tips welcome. 


Thanks,
Bill

Hello, 

As a result of the difficulties of ModusToolbox i have been attempting to use the Mbed Studio with the PSoC64 Wi-Fi BT Secure Boot Pioneer kit. I have been able to build the given program 'mbed-os-example-blinky' as well as debug it. However it is not not working as anticipated. I believe the LED is not mapped to the correct GPIO pin on the board. Does anyone know how to do this?

Hello everyone, I use MCU that has 3V3 output and 5V input tolerant pins, but for my application I need to have 5V output and 5V tolerant input pins. How can I achieve this? Expander is not in the option because it needs SPI/I2C drivers in firmware, and I want to avoid that. I can make 3V3 pin output into 5V pin output using MOSFETs but then the input part is tricky. 
Thanks in advance ! 

Dear team

I would like to use the MA5302 to create a single-supply, single-ended input stereo amplifier.

There was an evaluation board for MA5302 with positive and negative power supplies and single-ended input, but this does not seem to be compatible with a single power supply.

Therefore, I am thinking of creating a circuit for 2 channels using the evaluation board below as a reference.

https://www.infineon.com/cms/jp/product/evaluation-boards/ref_ma5332btlsps/

I have two questions regarding the above.

① Does the supply voltage need to be +40V?

Since I only need to be able to get an output of about a few tens of W, I would like to first make a simple evaluation using a commercially available switching power supply.

(If possible, we would like to be able to evaluate by inputting 30V or less.)

② If I use a single power supply, do I need to make the audio input differential?

I would like to use single-ended input if possible.

Best Regards,

TOMMAT

Hi,

Can you please advise if the CYW20829B0-P4 module supports Zephyr? If not, is there any plan for that?

Hello,

we ported the wifi stack in our new product, it has a WiFi stability issue, mainly it shows SDIO bus communication error, we made a restart stack when it happened but we don't know where is the root cause, can you help us with this?

Thank you very much!
