IMX ADC DRIVER

Currently only AD0 and AD1 are supported. MX6 ADC driver support through the following kernel configuration option: Both ADC controllers are bit resolution, right justified, unsigned format. The necessary driver support is available with version 2. This page was last modified on 18 April , at To determine which entry corresponds to which driver read the name descriptor with:. Keep in mind that opening and closing a file for every ADC read-out is relatively slow and rather resource intensive.

Analog-to-Digital Converter (ADC)

By just enabling the buffer ADC switches to continuous mode. The ADC peripherals also include an internal temperature sensor.

An analog-to-digital converter abbreviated ADC is a device that uses sampling to convert a continuous quantity to a discrete time representation in digital form. From Texas Instruments Wiki. For BSP versions 2. ADC, Sitara, Touch screen. These four addc inputs are compatible within the Colibri family and asc dedicated ADC inputs. On BeagleBone platform, P9 expansion header can be used.

The ADC channels are only 1. Copyright Product page More documentation.

The device tree must contain entries for: The ADC function of these pins are not compatible with other Colibri modules. Continuous capture mode is not currently supported. For further information of J8 connector layout please refer to EVM schematics here.

Views Read View source View history. You will only need to specify the IIO driver. The parameter “ti,adc-channels” needs to hold data related to which channels you want to use for ADC. For technical support please post your questions at http: On the ConnectCore 6UL there are:.

MX6 ADC driver support through the following kernel configuration acc You can find the source code for ADC here. We created a test program to show how the driver can be used, see adc-test. Contents [ hide ].

Vybrid provides support for continuous sampling with its ADC peripheral. The generic buffer code present in Linux kernel source tree can be used to test the continuous sampling functionality.

This aadc has been accessed 36, times. Both ADC controllers are bit resolution, right justified, unsigned format. It should be noted, that the noise level on these pins might be higher than on the dedicated ADC input signals, as these are routed as digital signals on the module.

ADC (Linux)

This example describes how to enable i. Access through sysfs is easy to implement since it only involves reading a regular file.
