#129691 - Help me on phillips isp1160 host programming plz |
i am developing a host systems using phillips host controller isp1160,
but i am facing problem during the enumeraion process. i am using a 89C55 uc and 95288 cpld together. the problem i am facing is i just cant understand that how to send the request packets(device descriptor,config desc,endpoint decs etc) on usb from isp1160 (as isp has its own buffer and we have to write it in to it(with PTD header)). i wanted to know more about the CONTROL TRANSFER process. how to respond to packets and how to give the handshake packet? i am just not getting it right.. can anyone help me to understand that how should i follow the whole sequence? how should i communicate with peripheral? |
