Problem is, i don't know how to see exported gpio pin in device tree so I can assign it as conversion-start pin in device tree node of ltc2308. Also, I tried to add PIO component and assign it to GPIO header, to make it work like it was done on this example: gith...
Hi all, moving to Yocto and in particular to the kernel 3.10.17 I need to adapt a driver that used a gpio as interrupt, in the former kernel 3.0.35,

一個GPIO擴展板(可選,但是推薦使用) 一個LED 您還會需要一些通用設備,例如: • 電阻值在220Ω~1000Ω之間的電阻 • 一個USB鍵盤,或者SSH連接:可以讓您輸入指令的設備 • 跨接電纜或電線 • 一個下推按鈕 連接電源軌 如果您使用的是擴展板,請將其連接到Raspberry Pi和麵包板上。然後將3.3V電源引腳連接...
In sysfs each GPIO within a chip would be exported and used individually. The GPIO character device allows for one or more GPIOs (referenced via offsets) to be read, written, configured, and monitored via a "linehandle" fd that is created dynamically on request. ...

Solved Jump to solution I'm using the Stratix 10 for DDR data acquisition. This part of the function is migrated from CycloneV, and the correctness of data acquisition is verified in cycloneV. But when I used Stratix 10's GPIO ip check ATLDDIO_IN ip core for...
The invention discloses a device and a method to achieve a camera function based on a general purpose input/output (GPIO) stimulated data bus. The direct connection of a main processor and an image sensor is used in the device, a data bus of a camera is stimulated by eight GPIO ports ...
