Apologies ahead of time if my terminology isn't spot on, pretty new to this.
What I'm trying to do is accurately time LOW to HIGH events on 8 separate pins relative to each other. I've calculated that I need 32 bit timers to work at 84 Mhz, but need two timers to do so since each has 4 direct input capture channels. TIM2 and TIM5 are the only 32-bit timers on the STM32F4.
Here are the problems I'm having:
1. I'm having trouble synchronizing TIM2 and TIM5.
2. It's possible each Channel on TIM2 is connected to the same pin as the Channels on TIM5. If this is true then I might not be able to use these two timers in this way.
Any weigh ins on these issues, or any advice generally is welcome!
