Dear All, I am new to the ARM and KEIL. I plan to develop a system containing usb host/device. I see in the website the rl-arm functions and also middleware doing this. But I don't understand the difference between them. It only came to mind that the rl-arm is containd the mdk v4 and the middleware for v5 ( may wrong ).
I have tow question: 1- What is the difference between them? 2- What is the correct solution to my application?
Best Regards, ras
And how do you know those are rl-arm functions?
