thanks for reply Put the clock in the camera comes out give data.(8bit)
So I made read clk and recived data. However, the speed of reading data from a GPIO through the mmap was slow to solve the problem, but a problem occurred a slow in clock speed makes the BeagleBoard So I have such a question. 2015년 7월 28일 화요일 오전 3시 43분 44초 UTC+9, Karteek YV 님의 말: > Use PRU to read/write I/O pins which can be done in 5ns.
