Hi to all, I am new in keil v5 and i want to implement usb ufi class mass storage under cbi protocol and i want use keil usb custom class in order to done that,but i do not know how i can use keil custom class and port it to my MCB17000 board and after searching in internet i do not find anything about that. Can any one me how can i create and config project with keil usb custom class??
as i said i want to implement ufi spec under cbi communication protocol so i need 4 endpoint as below :
endpoint 0 : default control endpoint endpoint 1 : bulk in and out endpoint endpoint 2 : interrupt endpoint
i add these endpoints to USBD_Config_CustomClass_0.h as i need, but when leaving processing of SetConfiguration command to usb_stack it fail to handle it, i say this because after receiving this command and i return usbdRequestNotProcessed, usb_stack do not call USBD_Device0_Endpoint0_SetupPacketProcessed function that must call after processing received command. also after leaving this command to usb_stack i dose not receive any setup packet in USBD_Device0_Endpoint0_SetupPacketReceived function. now i am searching for solution for this problem.
I can already point one problem if you setup your endpoints as described, by documentation LPC17xx microcontroller has specific endpoint types for specific endpoint numbers for example endpoint 1 can not be of bulk type but only interrupt, and endpoint 2 can only be of bulk type. So, I first suggest you reverse to use endpoint 2 as bulk, and endpoint 1 as interrupt.
you are my best man Milorad, it worked and my problem was that you point. because i was in hurry to done this project i didn't read lpc17xx datasheet. thanks again.
Ignoring the data sheets seldom speeds up the progress.
