Posted on July 30, 2013 at 07:48Hi guys, it's been a few years since I've worked with the timers on these micro's and I've been rediscovering how much of a pain they can be.Please refresh my memory so I at least know whether i'm wasting my time or n...
Posted on January 29, 2017 at 17:22The attached project is made up of CubeMX 4.18.0.If you open the project after opening the project at CubeMX 4.19.0 and then creating source again, an error occurs.
Posted on July 10, 2015 at 11:34I am planning to program stm32f103 micro controller over the air. I have a sim808 module connected for network connections. Any new firmware changes needs to be pushed to the microcontroller via sim808. Can this be ac...
Posted on January 23, 2017 at 07:43Hi,I am trying to use a TFT with ILI9488 via SPI. The Display works but it is incredibly slow. What am I doing wrong ?I am using FreeRTOS and LWip in my project, too.It would be great to get a hint or two.ThanksMar...
Posted on January 31, 2017 at 23:25I want to synchronize micros that each have their own clock. Is that possible? I was thinking of having a Master control the synchronization with GPIO. Essentially, when the pin is high (or low), you start whatever...

Posted on January 31, 2017 at 17:00Hi,I'm having no problem using the DMA in basic functionality, but I've run into something I can't figure out by my self.I'm having a STM32F207 processor and try to use SPI2 at the same time as UART4.the TX interr...
Posted on January 31, 2017 at 18:19I am using an STM32 F437 processor and the broken code I inherited uses the DMA to handle traffic from UART8. I am still grasping at straws a bit trying to find the best sources of information. So I am hoping someo...
