QTLEDTEST – software TO assess OLED displays

A few days ago we featured the USBPass, an offline password keeper made with very few components. At the end of our write-up we discussed that [Josh] was already working on another version of his hardware, which involved adding an OLED screen to the platform. To help him pick one he created QtLedTest, a Qt-based tool that simulates different OLED displays and GUI layouts for them. Internally QtLedTest is composed of QLedMatrix (a widget that simulates LED matrices), an SSD1306 OLED controller simulator, a easy graphics drawing library and some functions to draw text on the simulated screen. [Josh] used Fontbuilder together with a program he made in purchase to convert fonts he had found on the Internet to C files. All the source code [Josh] made can be found on Github and ought to be updated in coming weeks as the final program is a bit slow to render the simulated screens.
