hello dears... I'm a beginner to nano pi but a kind of professional in electronic and c programming.
I have a nano pi 2 fire with its 7 inch standard LCD. i have boot it with android. but now i have a electronic circuit like a metal detector with SPI out that can connect to any controller. i want to make a program for nano pi that comes instead of its Operating System (like android), that connect to my circuit and shows my own menus and run my program. actually Im reading many books about linux kernel, GCC and programming but i have no idea where should i get start. maybe i should start with programming on a OS like android and make it do my own or maybe not. i need some leads to where should i get start and good references or tutorials(other than nano pi wiki tutorials). i have done this job with an earlier version of ARM controller like cortex M3 and operating systems like RTOS.
I would be so thankful to anyone can help me.
by the way, I have an apologize about my English that in not so well.
