is it possible to have a OUT transfer (from host to device) to a large endpoint (2,4,6 or 😎 with a size less of 512 byte?
CY7C64713上电能正确被识别，用CyControl或者CyConsole加载Examples中固件（比如Bulkloop）到到RAM不能被电脑识别，但是加载同样一个固件（Bulkloop）到64KB EEPROM却能被正确识别，请教这是什么原因？Show Less
I am developing with Windows 7 - 32 bit. I am using CyApi with CY68013A. Can I use CyApi transfer functions ( p.e. XferData..) from two thread without mutex or semaphore, or I need to protect every call with mutex or other?
I purchased a CY763813-PXC and I wish to program it. I have no trouble making a programmer myself so I want to do that. However there is one issue: I cannot find the specifcations for the chip to program it. The closet thing that I could find is this http://www.cypress.com/?docID=41612 however nowhere is the CY7C638xx family mentioned. The datasheet for the family on brifly mentions this topic. The datasheet that I am working from was obtained from here http://www.cypress.com/?rID=14212
The enCoRe II devices enable this type of in system
programming by using the D+ and D– pins as the serial
programming mode interface. This allows an external controller to enable the enCoRe II part to enter the serial programming
mode, and then use the test queue to issue flash access
functions in the SROM. The programming protocol is not USB.
Now the question is how do I get into test queue?
Also right on the first page of the family datasheet it says "Industry standard programmer support" but what standard?
If anyone has more information on the protocol to program this chip please do tell.Show Less
What is the status of CY7C64613 microcontroller? It is not present on obsolete products list. It is not listed on product page. I found link to DS in (ID: kku03021901) post but it doesn't work.
If this is obsolete can you recommend replacement with similar or the same functionality?
Thank you in advance,Show Less
The PC host sents USB Request Block to CY7C64713,Firmware How to response the URB?

Hi, I met a strange problem: I wrote a little software by visual studio, in this software, I read desk file and send it into cy68013a chip. In the beginning, transfer is right. But after several transfer, I can only receive 00 and 01 value, whatever to send. I think it may be the driver problem, do you have any idea to solve it?
Thanks a lot!
