Posted on September 21, 2015 at 18:53I have an issue that seems to be related to some fundamental lack of understanding about GPIO behavior that I can't figure out.  The most clear symptom I have identified is this:I'm working with an STM32F405RGT6 ...

Posted on September 08, 2015 at 17:49I'm working on a sound-reactive project with the STM32F405 that samples ADC for FFT.  I'm currently using double-buffered DMA triggered by TIM3 TRGO.  Everything is working but it's very rough around the edges an...

Posted on April 13, 2015 at 23:22I'm working on a very space-constrained design for an STM32F405RGT6 that needs 48MHz for USB FS.  Ideally the crystal is a 3.2mm x 2.5mm footprint.  Availability suggests that 12MHz is a perfect HSE for my needs.  I'...
