I don't think this one does, but the other models such as beaglebone black have 2, 200Mhz microprocessor cores that can access GPIO and shared memory in realtime (without an RTOS). It's a killer feature, you can have the best of both worlds. For example, a python program running in userspace, interacting with a microcontroller doing GPIO stuff quickly and in realtime.
- dekhn 3y agoI known the BB can do this. T he question is if any of those SBCs do realtime gpios. Raspi SBCs have gpios but you can't trivially write an interrupt handler than runs in kernel space
