Users » Nakor » Code » uOLED

Heavily documented control library for the uOLED-96-G1 (SGC) by 4D Systems. Will likely work with any of the 4D Systems serial controlled screens. <<info>> All examples in the documentation have been tested to the best of my current abilities, but there are a few functions that I simply do not use. I have created a Lighthouse page for this library. You may submit bug reports or feature requests to [[http://mbed-uoled.lighthouseapp.com|this page]]. If you really do not wish to sign up for a Lighthouse account you may also post any bugs or requests [[/users/Nakor/notebook/uoled-bug-reports/|here]]. <</info>>
