Input Digital component

Allows the values from a buffer to be assigned. Either a value at a time or from an array. The input signal would usually take the form of an ADC reading or raw data values.

Detailed description

Examples

Here is a basic example demonstrating how to pass a value into the DSP chain. Delay The input value in the example uses an ADC reading but this can be taken from anything such as a reading from a CSV file on a SD card or a value passed by a sensor on a I2C bus etc.
