Working with the STM32F439 UART and originally used DMA for TX and RX, and that was working. For other reasons I wanted to change RX to use interrupt, and I had difficulty getting it to work... I got things work...

Having trouble changing the STM32F4 clock (M4 clock) on the fly, dynamically. When I do, the target fails, sometimes not right away, but within a few dozen seconds. How do I know its failing? I have a task att...

Posted on February 16, 2015 at 04:32To be clear, I am using Tickless mode. I believe I have verified that the systick timer is not firing because the IDLE hook is only running when the tickless counter goes off, about every 2sec with my current clo...

I actually I did not solve my problem... In the IDLE hook I use,

And I am finding I am always getting interrupt, so it doesn't stay in STOP mode for very long. The inte...
Posted on February 12, 2015 at 19:23I am also doing this and seem to be missing something fundamental. Background, my system is using FreeRTOS and STM32F429, it works, and when I enable tickles mode, it still works, and the current reduction is as ...
