Hi,
In my project, we are going to use 2 mcu. One is main mcu, the other is backup mcu. Now these two units have the same job. when first boot backup mcu is triggered to sleep mode by main mcu.
The main question is : These two mcus are connected as parallel. And I do not know how gpio pins react at this connection? I haven't test it yet, but if add diode for all gpio pins can i use these two mcu's gpio for the same job? I mean, does this diode connection provide me a safe operation field while one mcu is running and the other one is sleeping?
If the above idea will fail, can you suggest me any application note or something for this parallel connection topology?
Best regard.
