Precise delay with counter 8

Precise delay with counter

If you work at high speed, as STM32F4 devices do (84MHz or more) then this tutorial is not right for you. But, you are able to descrease system speed to any frequency basicly you want. If you want to use delay with systick down timer, look at my library here. You can use great solution, Systick timer to make an interrups for you. But you can also decrease speed to let’s say 42Mhz, and that systick every 42ticks checks for...

Sometime I made a tutorial how to work with something on STM32F4xx device, because is hard and pointless to make library for it for any reason. Tutorials are set to work at least with STM32F4xx devices. Tutorials NR Name Description 1 FIRST TIME First time with STM32F429 Discovery.
