Try looking at the SysTick_Handler() in STM32F4-Discovery_FW_V1.1.0\Project\Demonstration\stm32f4xx_it.c

I'd start by not calling TIM4_Config(), which changes the GPIO pins to AF (Alternate Funtion) mode. The LEDs LD3, LD4, LD5, and LD6 are conveniently behind TIM4 channels, but you can leave them in GPIO mode.
You should then be able to use : STM_EVAL_LEDOff(LED4); STM_EVAL_LEDOn(LED4); STM_EVAL_LEDToggle(LED4);2013-01-09 10:33 AM
