Posted on January 26, 2012 at 18:17It would seem to me given the way the GPIO pins are mapped to EXTI lines, there is no way to use two pins that have the same GPIO pin number. For example, in my case I would like to use pins A8 and B8 as separate ...
Posted on December 14, 2011 at 20:35I currently have code which runs on the STM32F4-Discovery board and DMA's data from the ADC to a buffer. I am using double buffering, so I can operate on one buffer while the other is being filled. In short, my ...
