PSoC™ 5, 3 & 1 Forum Discussions

Hi,

I'm not as experienced on USB-related programming overall.

I happen to be using a PSoC5LP and the USBFS in UART (CDC) mode (with the USB_UART component).   I assume this question can apply to USB CDC communication in general.

The issue:

I can detect when the host PC opens a serial port using the EP0 (end point 0) interrupt service.

I'm trying to detect when the host closes the serial port.   I can also see the EP0 ISR is occurring at this time.  

I'm trying to decode what messages from the host is being sent with no real success.

I've looked on the USB 2.0 specification and cannot find any info about what requirements the host must do when informing the device on the other end that the port has just closed.

I would appreciate the help in pointing me in the right direction.  Thank you in advance.

I create an example project about USBFS UART for cy8ckit-059 and I want to know why my laptop can't detect the device when development board is connected to the laptop via micro usb.

I am programming a PSoC3 Microcontroller (CY8C3246PVI-147) via the PSoC Creator 4.4 software.

After adding some functions during compilation I get the following errors:

*** ERROR L107: ADDRESS SPACE OVERFLOW

SPACE: CONST
SEGMENT: ?CO?CYFITTER_CFG
LENGTH: 00098BH

*** ERROR L120: CONTENT BELONGS TO ERRONEOUS SEGMENT

SEGMENT: ?CO?CYFITTER_CFG 

Program Size: data=71.5 xdata=4752 const=2443 code=53415

The command 'LX51.exe' failed with exit code '2'.

In the .map file there is this:

Would anyone be able to advise me on how to solve this?

Thanks

I'm using the PSoC5 component UART V2.50.

I'm trying to send out a data stream of 8-bit bytes with 90% of them being with MARK parity.

I tried multiple coding experiments to try to get even just one byte with MARK parity.   All the bytes ended with SPACE parity.

I followed the directions in the UART datasheet.  No luck.

I'm probably missing something here.  An example program where all the bytes sent as set as MARK parity would be helpful.

As a side note:   I created a kludge using a SPI Master to generate the 11 bit pattern with MARK parity for transmission.  The UART can successfully detect when MARK parity occurs (although it doesn't flag a parity error just indicates the status of this bit).  

The sad part about the SPI Master kludge is that the SPI data begins (not a problem) and ends (a problem) with '0' after the transmission is complete.  This causes a false start bit for the next data being received to all other multi-drop devices on the line.

This is related to my previous post: I-need-a-UART-configuration-that-supports-8M1-8-bit-MARK-parity-1-stop-bit 

Hello everbody,

i hope you can help me a little bit.

At the moment I am trying to program a PSoC 5 (CY8C5268LTI-LP030) with the CommandLineInterface.
Unfortunatey it isn´t working properly 😞

What have I done...

At the moment I am using this commands in a script:

OpenPort KitProg/0720063201324400 C:\Program Files (x86)\Cypress\Programmer
HEX_ReadFile "C:/HexFile/Testfile.hex"
SetAcquireMode "Reset"
SetProtocol 8
SetProtocolClock 152
SetProtocolConnector 0
SetPowerVoltage 5.0
//PowerOn
DAP_AcquireChip
PSoC3_EraseAll
PSoC3_ProgramRowFromHex 0x03 0 0
DAP_ReleaseChip
ClosePort
quit

Till the command "PSoC3_ProgramRowFromHex 0x03 0 0 " everything looks good. But while using this command I get following error message:

"PSoC3_ProgramRowFromHex 0x03 0 0
E
Timeout of SPC polling. Lost communication with chip (Status = 0x00)
PSoC3_ProgramRowFromHex 0x03 0 0 returned 80004005
80004005 OK"

And I am not sure how to fix it. I don´t know the problem... Is there anybody with an idea how to fix it?

Question 2:

Is there a command to program the whole hexfile without the rowId and arrayId? For example the command Program(). Unfortunately the UserGuid tells me it is only for PsoC1 😞

And is the arrayId 0x03 the correct id?

Many thanks in advance. I hope somebody can help me! 🙂

Ando some more informationen.
I am using a KitProg2 and the programming with PsocCreator oder PscoCProgrammer is working without any problems. So I guess there is no hardwareproblem.
