USB low-full-high speed peripherals Forum Discussions

I have been working with the composite device example lately. One of the things I would like to know is where is the source code for

void Scan_Keypad(void);

void Keyboard_LEDs(void);

void Volume_Control(void);

When I try to do a right click to find the definitions and references it only provides a message that says:

We were unable to find the symbol 'Keyboard_LEDs. There are several things that can hinder symbol lookup:

  - Make sure your project compiles without errors.

  - Make sure your "Generated Source" has been generated (Build -> Generate Application).

  - Make sure your .c files #include their corresponding header files.

Find results for 'Volume_Control':

----------------------------------

C:\Users\Randy\Documents\PSoC Creator\Composite Device\Composite Device.cydsn\main.c - (line 18, col 6): void Volume_Control(void);

Matches found: 1

Any ideas ?

I've been given the task of changing some usb buttons, and testing indicates that they use the enCoReII Keyboard RDK. Digging around, the documentation here indicates I need a PSoC MiniProg programmer and a 5-pin to USB interface adapter. Looking around further, I can't find any 5-pin to usb interface adapters and i'd rather not have to make one, so would I be able to re-program the button using the PSoC MiniProg 3? If not, is there another alternative?

hello. I used CYUSB2014-BZXC chip for getting data from GPIF.

CYUSB2014-BZXC Booting mode is usb boot. and I did upgrade firmware with RAM mode

The configuration of my board is as follows.

CYUSB2014-BZXC is conneted with ARM CPU by USB 2.0 Interface.

data line is conneted with CYUSB2014-BZXC by GPIF ( use 0-7 data line. and data valid line is connected with GPIO18.  and CLK line is connected with GPIO16 )

At first, the CYUSB2014-BZXC chip was recognized normally in the kernel.

I used the GpifToUsb example source to create the firmware, apply it to the board, and test it. At some point, the chip is not recognized.

After that, it is not recognized even if hardware reset is executed.

As far as I know, I know that hardware reset will boot with default firmware.

When the kernel is booted with hardware reset, the CYUSB2014-BZXC is not visible on the usb bus. Running lsusb or running 01_getdesc does not show CYUSB2014-BZXC on the usb bus.

I want to know how to fix CYUSB2014-BZXC. And I want to know why this is happening.

Hi

whenever i used to program the eeprom (24lc128) on development kit FX2LP(CY3684) ,following error occur "EEPROM NOT ENABLED"  Is there any way to load / program the new eeprom according to development kit FX2LP(CY3684)?  Below is the link of website from where i bought the new eeprom for development kit FX2LP(CY3684).
