task_share module¶

Interrupt-safe inter-task data sharing for MicroPython.

Provides Share and Queue classes that allow tasks to exchange data without risk of corruption from interrupts. Shares hold a single value; queues provide a FIFO buffer. Both use MicroPython’s micropython.schedule / IRQ primitives to guarantee atomic access.
