Re: Interrupt triggered DMA

In certain automotive modules, data like that is logged and stored by using a circular buffer that is updated every sample (i.e., data is ALWAYS being logged). When a worthy trigger event occurs, data from X sample before the trigger and Y samples after the trigger are then set aside to be written to non-volatile memory.
