How to use the SAMA5D2 ADC
in Linux®
Today's recommended application note will provide information on getting started with the SAMA5D2 ADC under Linux. By introducing the Industrial I/O (IIO) subsystem into the kernel, the ADC device in user space can be easily accessed using sysfs or device nodes. The device driver for the ADC in SAMA5D2 is implemented based on this subsystem. With the standard interface of IIO, applications can be easily developed/ported to user space.
Since the ADC function is implemented in kernel space, this article will introduce how to use ADC in user space.
