USB low-full-high speed peripherals Forum Discussions
This question was not quite fully-answered...for my application, I have a mux setup for multiple SPI devices.
Specifically: I need to know the minimum time from SSEL_OUT assertion (going low) to start of the SPI master clock action.
Thanks.
Show LessHi,
What is the "state of the art" Tool chain to be used to developt a firmware onto FX2LP18 ?
I've currently the SDK you provided onto your website (quite old ...) using Keil V2 Project and Examples (Keil is now V6).
With limited code size : 4 Ko.
Do i need to stay onto uvision V2 ? and Ask Keil for a Full License ?
Is there any "free" solution using another free compiler/linker ?
Regards.
Show LessHello,
I would like to configure the CYUSBS234 as an SPI slave and am trying to figure out if the RX/TX LEDs are on GPIO8 and GPIO9 like the datasheet says, or if they are on GPIO0 and GPIO1 like the configuration utility guide has them?
Thank you,
Jake
Show LessHi,
I 'm using C# code from an application note (AN63620).
I need to send infortmation SETUPDAT[6] and SETUPDAT[7] to my Firmware.
C# APPLICATION SIDE :
CtrlEndPt = myDevice.ControlEndPt;
CtrlEndPt.Value is REPRENTATIVE of the valueParam SETUPDAT[2] & SETUPDAT[3] : RIGHT ?
CtrlEndPt.Index is REPRENTATIVE of the indexParam SETUPDAT[4] & SETUPDAT[5] : RIGHT ?
But What About lengthParam ??
Is there any way to set SETUPDAT[7] and SETUPDAT[6] in the code application C# side ?
To pass this information to the FX2LP18 firmware ...
FIRMWARE SIDE :
// Retrieve parameters, sent in big endian format for STICEX vendor requests
// (thus not respecting USB-2.0 spec, but 8051 processor endianness).
// The 8051 is a big endian processor => no byte swap required, simply
// cast the pointer
valueParam = *(WORD *)(&(SETUPDAT[2]));
indexParam = *(WORD *)(&(SETUPDAT[4]));
// The length param is sent in little endian format by the CyUSB driver,
// respecting the USB-2.0 spec.
// The 8051 is a big endian processor => byte swap required
lengthParam = ((WORD)(SETUPDAT[7]))<<8 | SETUPDAT[6];
Thanks for help.
Show LessHi. All.
This question is related with AN61345 application. link https://www.cypress.com/documentation/application-notes/an61345-designing-ez-usb-fx2lp-slave-fifo-interface
My customer asked why is different between slave.iic file(in zip folder *) and slave.iic after keil compile.
* AN61345 Designing With EZ-USB FX2LP Slave FIFO Interface - Source code.zip
They said the original file is ok on their board but the compiled file is some strange.
We changed product ID to 0310. then, We found the descriptor is changed to FX2LP. but the working is not same.
It is not same the hex file and iic file after compile.
Could you explain what is a problem? and Can you share Previous AN61345 FW if you have?
Regards.
Robert.
Show LessHello everyone,
I am beginner working with CYUSBS234, I tried testing SPI communication with internal EEPROM and I had successful results, but now I want to use SPI communication to write data in a flash memory (chip 6D25Q64C), I connected #2 pins of J17, J19, J20, and J21 to the external chip according with https://community.cypress.com/docs/DOC-10837 but now I dont know how to procedure, I tried using the USBSerialTest Utility, I clicked the "Write data" button, but when I clicked the "Read & verify data" button, a warning message tell me that the data verification failed, and shows me the buffer data which always is full of zeros.
Could anyone of you help me please?
Show LessCan the CYUSBS234 DVK have the CY7C65211 swapped out with the A version to be configured in SPI mode as a virtual COM port? If so will the configuration utility allow the SPI configuration?
Show LessCan I use a development kit CY3684 to debug the firmware for CY7C68014A-56PVXC? The development kit uses the CY7C68013A-128AXC which also has access to the serial port for the KEIL debugger. I don't need all the functionality of the 128 pin part and the power consumption is also a benefit is the reason to use CY7C68014A-56PVXC
Thanks in Advance!

Show LessHi Sir,
客户的产品是各种摄像头模组,通过CY7c68013将图像数据传递给手机,客户的产品已经量产,最近客户反馈,在华为的新款的手机无法识别CY7c68013,并且只在华为的新款手机上无法识别,手机年份大概2018年以后的都不行,以下是客户提供的手机系统的截图,请问这是什么原因呢,谢谢。
Hi Sir,
Customer's product is all sorts of camera module, through CY7c68013 pass image data to mobile phone, the customer's products have been mass production, customer feedback recently, in huawei's new phone unable to identify CY7c68013, and only in huawei's new mobile phone can't identify, mobile phone probably after 2018 year are not, the following is screenshot provide mobile phone system, what reason is this excuse me? Thank you.
