Hi,

I have been working to implement a circuit on PSoC5LP MCU as the PSoC5 LP MCU supports both analog and digital peripherals but in analog we have 4 comparators and 4op-amps, what in the situation if we require MOSFET in the situation, then what should be my approach? 

Anyone Please do let me know, waiting for your reply.

Thanks & Regards,

Prateek

Hi,

Could you please help me with Schematic and firmware design support to drive Segment LEDs using the PSoC 5LP chip?
We have to drive a seven-digit seven segment display with various segment current from 16-bit serial input.

Dear All 

I have some question about how to install EZ-PD™ Protocol Analyzer Utility (USB PD3.0).

We installed EZ-PD™ Protocol Analyzer Utility (USB PD3.0).

However, the attached message is appeared and cannot execute...

*EZ-PD^™ Analyzer Utility (USB PD2.0) is installed and we can use.

Hello.

I'm using CYW943907AEVAL1F.

I load "snip/sd_filesystem" code.

I put on uSD receptacle this model of uSD Scheda MicroSD PRO Endurance - 2018 (128GB) | Samsung IT

This uSD is a 128GB, interface UHS-I, Class 10.

Line 375 of "sd_filesystem.c" calls "wiced_filesystem_mount .. WICED_FILESYSTEM_HANDLE_FILEX" fails.

I dont' understand, in datasheet "002-14829 Rev. *K" page 18 I read UHS-I modes are supported.

Dear Sirs and Madams,

The item "Table 3. External Clock Input Requirements" is defined in AN72332, where "Rise time / fall time 3 [ns] (Max)" is specified. 

Please tell us this voltage condition. (For example, 20% -80% VCC, not specified, etc.)

Hello.

I write this simple code and launch it on CYW943907AEVAL1F.

This simple code configures BCM43907 as WiFi Direct Group Client.

void application_start(void)

{

    /* Initializes the WICED system */

    wiced_init ( );

    /* Lauch CONNECTION_P2P_GC */

    if ( connection_launch ( CONNECTION_P2P_GC ) != WICED_SUCCESS )

    {

        WPRINT_APP_INFO( ("connection_launch failed\n") );

        return;

    }

}

If I launch this code and I try to connect my HUAWEI MediaPad T5 (Android 8.0.0) using system menù

the connection works properly. Really sometimes the connection failed.

I obtain this Log.

usb device work wrong under static electricity test in 6kv.   when device works wrong , we cant get any uvc or cdc-uart data in bushound, but down channel still works well at the same time.  and then the device can return to normal state after reconnect and without poewroff.  i want to make sure what will make this and if any useful state can be used to help solve it？

Hello,

I  have configured the HX3 CYUSB3314 - 88 pin through the HX3 Blaster plus SW, and set the EMBEEDED HUB BYTE to 1, because my USB Upstream link cannot be removed by a user ( Embeeded in a product). My Hub is powered externally ( VBUS is not used) . 

However, when i cut the Vbus Upstream wire to simulate a default, or a perturbation, the Hub detect it and disconnect. Is it the appropriate and expected behaviour ? What is the purpose of this setting ?

I'm currently using the ihx3_revb_b7 firmware.

Thank you for your help,

I am working on a Flash Write routine which is part of a boot loader for the CY8C27243.  I am using Application AN2100 as a starting point. I have all aspects of the bootloader working except for Flash Write.  After many days of debugging I have narrowed it down to the Supervisor ROM Flash Write sequence which uses the M8C SSC instruction. 

Here is a simplified sequence used to access a supervisor ROM routine as found in FLASHAPI.asm which is part of AN2100. This is part of the temperature table access routine and is a very simple use of the supervisor ROM and should work.

push A   ; save the State variable
push X
mov X, SP   ; copy SP into X
mov A, X     ; mov to A
add A, 3     ; create 3 byte stack frame
mov [0xF9], A   ; save stack frame for supervisory code
mov [0xF8], 0x3A   ; load the supervisory code for flash operations
mov A, 6    ; load A with FLASH_TEMP_TABLE_LOOKUP rom code
SSC          ; SSC call the supervisory code
pop X

Code execution does not return after the SSC instruction. I am assuming it is halting for some reason.

I have double checked all of the parameters and can't figure out what I am doing wrong.  Can SSC only be called when the M8C is in a certain mode ?  I have been able to read Flash successfully since that routine uses the absolute ROM read instruction ROMX which avoids an SCC. I wish there was such an easy way to do a write.

I have been working on this bootloader for nearly a month now and need to finish this before new product release.  

Hello,

I am designing a product for medical liquid sensing and I am a bit lost in all your products.

My tank is about 20cm high, and I need a 1mm accuracy (so 200 divisions). My sensor PCB can be up to 3cm wide (so 20cm x 3cm for sensor).

The distance between the liquid and the PCB is 2.5mm PVC, 0.5-1mm air, and 1.5mm ABS.

I was wondering if you had recommendation on which product to use, and how many (segmentation of the sensors). I already have a microprocessor in my product and only need the sensing part (via like I2C).
