I need to transfer data between Android phone and Pic micro-controller like pic18f6628. I have designed a board using Max3421e.
I dont know how to configure Max 3421. I have seen that there are Arduino USB shield Libraries are available but there are lot of file and i have never worked on Arduino.
How much code is required on micro controller side for this task?
What's the use of this question?
With no single requirement from your side and no information about language...
Let's imagine someone answers "54 lines".
I want to use c with MPLab X ide. First i thought that i just need to configure spi and internal registers of Max3421. But after doing some search i found that Max3421 provides low level usb interface, USB protocol is required on micro-controller side.
