USB low-full-high speed peripherals Forum Discussions

We manufacture our own hardware in house and we are using the cy64713 chip FX2LP. We have sofware developed for windows and mac. The softwae is written in java. We have created a JNI written in cpp that works with a java interface. I am having issues with the jni specifically in the writeUSB function. Currently we are using the IOKit, CoreFoundation, CoreServices, and the JNI.h thats located at  

/Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home/include

and 

/Library/Java/JavaVirtualMachines/jdk1.8.0_60.jdk/Contents/Home/include/darwin

​

We are using Netbeans. I would love any advice on how to re write this code using libusb that cypress has shown in the SDK. I downloaded the FX3_SDK_MacOS_v1.3.3 and have been reading through the doc's. 

We do not sell any of this software so i can show you source code etc... 

This is the error dumb im getting...

JNI code here

https://bitbucket.org/snippets/partialdata/6L69r/ucs30interfacejni

Their must be an easier way to communicate with our hardware with a better JNI using libusb. I would utlimatly like to use a hid device not sure how to do that either so its cross platform. 

Is there a Windows CE 6.0 driver for the CY7C65211 USB-Serial device? The data sheet mentions there is and the dev kit also but the dev kit software package does not contain a driver.

Good morning sir,

Please let me know the why they they interfaced DS2411P with cy7c68013a cypress usb controller in the below attached schematic.

Thank you,

VM

#ifdef ALLOCATE_EXTERN
#define EXTERN
#define _AT_ _at_
#else
#define EXTERN extern
#define _AT_ ;/ ## /
#endif

EXTERN xdata volatile BYTE GPIF_WAVE_DATA    _AT_ 0xE400;
EXTERN xdata volatile BYTE RES_WAVEDATA_END  _AT_ 0xE480;

// General Configuration

EXTERN xdata volatile BYTE CPUCS             _AT_ 0xE600;  // Control & Status
EXTERN xdata volatile BYTE IFCONFIG          _AT_ 0xE601;  // Interface Configuration
EXTERN xdata volatile BYTE PINFLAGSAB        _AT_ 0xE602;  // FIFO FLAGA and FLAGB Assignments
EXTERN xdata volatile BYTE PINFLAGSCD        _AT_ 0xE603;  // FIFO FLAGC and FLAGD Assignments
EXTERN xdata volatile BYTE FIFORESET         _AT_ 0xE604;  // Restore FIFOS to default state

​I do not get it about "#define _AT_ ;/ ## /".If the file is first used or included,the ALLOCATE_EXTERN is not defined,the program will jump to "#define EXTERN extern".However ,"#define _AT_ ;/ ## /" will not make _AT_ function as the _at_ in keil.Somebody could explain this for me? Thank you so much.

I have been using CyAPI.lib (from Suite USB 3.4.7) successfully as part of a C++ program in Visual Studio 2010 and 2013, however I have recently upgraded to VS2015 and it is now producing linker errors regarding a _sprintf() function call within the lib file.

Has anyone found a solution or workaround for this or must I return to VS2013?

Many thanks,

Chris

I am following the docs on how to compile and get the examples to compile. I am not having any luck.

I am using mac book pro OS X El Capitan 10.11.1 

g++ -o cyisowrite_test            cyisowrite_test.c            -l cyusb -l usb-1.0    

clang: warning: treating 'c' input as 'c++' when in C++ mode, this behavior is deprecated

In file included from cyisowrite_test.c:7:

./../include/cyusb.h:18:10: fatal error: 'libusb-1.0/libusb.h' file not found

Hello together

I developed a board with CY68013 hardware. I tried a small usb example (CyAPI, CyUSB-Driver) with c++ and it works very fine but now I would like to used Borland Delphi for a Win32 application.

Does anybody of you know a programming example using the CyUsb-Driver also in Delphi?

Thank you for your help an best regards

Hi,

I notice the code which generated in GPIF Designer.

// Configure GPIF FlowStates registers for Wave 0 of WaveData
  FLOWSTATE = FlowStates[ 0 ];
  FLOWLOGIC = FlowStates[ 1 ];
  FLOWEQ0CTL = FlowStates[ 2 ];
  FLOWEQ1CTL = FlowStates[ 3 ];
  FLOWHOLDOFF = FlowStates[ 4 ];
  FLOWSTB = FlowStates[ 5 ];
  FLOWSTBEDGE = FlowStates[ 6 ];
  FLOWSTBHPERIOD = FlowStates[ 7 ];

I've no idea about this part.

Can you tell me what is the flow state? Are there any sections or chapter can explain it?

Hello,

I get a problem with the CY7C68001 chip recently.It Could communicate with PC successfully before.But now,it doesn't work normally.PC Can't identify the device.The external controller is TI F2812 MCU.So I want to know whether the CY7C68001 chip is damaged .How to  identify it from the pins or registers? Could anyone who has the similar experience give me advice.

thanks.
