Not sure if applicable, page 10 shows what looks like possibly push-pull I/Os, maybe. STM32 Understanding GPIO Settings seems to answer the question, 2nd thread answer/post. Library 02- STM32F429 Discovery GPIO tutorial with onboard leds and button e.g., this, and more, can be found: "GPIO_OType_PP: Output type is push-pull GPIO_OType_OD: Output type is open drain" Hope some of it helps.
