I am trying to implement a Time-Triggered CAN system using the STM32F103.
The User Manual states that it supports a Time-triggered option, but further reading indicates that all it appears to do is time-stamp sent & received messages. This is not actually much use as although I do need to know exactly when a message is received, I also need to control exactly when a messages is sent - not just get told when it was sent.
The User Manual also states that it has "Configurable timer resolution", but I can't find anything that says how to configure this timer. Is it the same as the bit timer?
If I have to do all my actual time-triggering stuff in software, is there any way to relate these timestamps to a meaningful time? Such as one that I can use in TIM1? An arbitrary free-running time is no use unless I can relate it to something I can use for triggering a transmit.
Any help greatly appreciated - even if that help is to, "forget the hardware and just do it all in software".
Cheers and Have a Good Day
