Methods and systems for providing computer implemented services using configurable hardware components are disclosed. To update operation of a configurable hardware component, a large amount of data may be provided to a single input/output pin of the configurable hardware component. The large amount of data may be encoded in a complex waveform corresponding with at least eleven bits of digital data. The complex waveform may be interpreted by the configurable hardware component to obtain the large amount of data. Using the large amount of data, the configurable hardware component may update its operation to be in condition for providing the computer implemented services.
