For coast down reason, i need put at least four CY7C68013A(EZ-USB-FX2) devices on one PC's USB ports, but i don't know how my application software to know which one is the correct one to control? or, if i open four instances of the application waftware, how can the four instances and the four devices can be one to one correspondence? thank you!
Hi, i'm sorry for hand slip to click the "report abuse". YES, I used CYUSB.LIB to create a application in vc++ 6.0 platform, this .lib has a function boolCCyUSBDevice::Open(UCHAR dev) to open different CY7C68013A devices, but i don't know how to sent data to the one device that i want. If the XferData() can know whiche device it shout send to? or someone else function can do it? thanks!
the structure of my design is:
useing application to download firmwire into CY7C68013A's RAM everytime when i open it.
useing Xferdata() to transfer data to CY7C68013A
when firmwire get the data, useing "switch" to decide which function should be called base on the data.
