IMX ADC DRIVER DOWNLOAD

However the internal ADCs are anyway not meant to be used for high speed applications. You can find the source code for ADC here. The generic buffer code present in Linux kernel source tree can be used to test the continuous sampling functionality. The ADC function of these pins are not compatible with other Colibri modules. The STMPE supports up to 8 analogue inputs, however, input are used for the resistive touchscreen interface. Open topic with navigation. ADC, Sitara, Touch screen.

The necessary driver support is available with version 2. Currently only software triggers are supported, they are accessible through sysfs.

To determine which entry corresponds to which driver read the name descriptor with: ADC channel mapping The i. Ims BSP versions 2. Copyright Product page More documentation.

These options are enabled as built-in on the default ConnectCore 6UL kernel configuration file. Access through sysfs is easy to implement since it only involves reading a regular file.

The STMPE supports up to 8 analogue inputs, however, input are used for the resistive touchscreen interface. The ADC samples the analog signal when “start of conversion” signal is high and continues sampling 1 clock cycle after the falling edge. MX6 ADC driver support through the following kernel configuration option: A new conversion cycle can be initiated after the previous data is read.

The ADC channels are only 1. However the internal ADCs are anyway not meant to be used for high speed applications. ADC, Sitara, Touch screen. To determine which entry corresponds to which driver read the name descriptor with:.

From Texas Instruments Wiki. Please note that the ADC output is positive binary weighted data. The inputs are 0 indexed, so the usable inputs are Both ADC controllers are bit resolution, right justified, unsigned umx. Keep in mind that opening and closing a file for every ADC read-out is relatively slow and rather resource intensive.

By just enabling the buffer ADC switches to continuous mode. Currently only AD0 and AD1 are supported. On BeagleBone platform, P9 expansion header can be used.

Read the input value of a channel with: The ADC drivers only support “one-shot” mode. Digi Embedded Yocto version 2.

ADC (Linux)

On the ConnectCore 6UL there are:. The ADC function of these pins are not compatible with other Colibri modules.

Read the input value of a channel with:. Starting with BSP versions 2.

Linux source code: drivers/iio/adc/vf_adc.c (v) – Bootlin

To learn the syntax of the application run: Kernel configuration You can manage the i. We created a test program to show how the inx can be used, see adc-test. You can find the source code for ADC here.
