This repository contains an object oriented library for Digilent devices. It is written in Python 3 and has typing information. Typing means this library incompatible with earlier python versions.
This library has been developed and tested with the Digilent Analog Discovery 2, however, the library is written to adapt to any digilent device supported by the digilent SDK. Using SDK calls, class properties are generated at runtime based upon the connected hardware.
Formally, only the object model of the AnalogDiscovery2 is supported. Object models for other digilent devices can be created independently in user applications by initialising the required classes. Some work is required to enable AnalogOut functionality and implementations for SPI, UART, and CAN peripherals.
To run, the package requires the Waveforms SDK to be installed. The SDK comes as part of the Waveforms software installation
