Hello, I'm currently working with a STM32MP157D-DK1 Development Board with 4GB DDR3L. I populated the board with a prebuild openstlinux 6.1 build like discribed in a guide in the ST wiki.When checking the total memory i unfortunatly only get 407MB th...

Hey,I'm using the Timer 2 in Encoder Mode TI1 and TI2. The Trigger Output of the Timer is set to Master/Slave Mode Enabled and the Trigger Event is set to Compare Pulse (OC1).As far as I know: This Timer will fire an internal interrupt via TRGO every...

Hey,I'm using a Nucleo-F446RE and the STM32 Cube IDE.I want to start the Timer3 with a changing Edge at a GPIO Pin. Then the Timer should count till another GPIO has a changing Edge aswell. Now the timer should be disabled and the counter should be s...

> Contrary to its name, the MSM but does not do much, just shifts one of the internal signals by one or two cycles."The effect of an event on the trigger input (TRGI) is delayed to allow a perfect synchronization between the current timer and its sla...

I could solve it.What made this process complicated was the fact, that i couldn't distinguish between counter clockwise or clockwise rotation of the encoder signal from the motor. To implement this by checking edges is (as far as i know impossible) i...
