This code has two different types of interrupts it handles differently: Shared interrupts and non-shared interrupts. The simplest
|
||||
of the two are non-shared interrupts: a separate interrupt is allocated per esp_intr_alloc call and this interrupt is solely used for
|
||||
the peripheral attached to it, with only one ISR that will get called. Non-shared interrupts can have multiple peripherals triggering

the peripheral attached to it, with only one ISR that will get called. Shared interrupts can have multiple peripherals triggering
|

it, with multiple ISRs being called when one of the peripherals attached signals an interrupt. Thus, ISRs that are intended for shared
|
||||
interrupts should check the interrupt status of the peripheral they service in order to see if any action is required.
