# Threading
|
|
|
|
MicroPython supports spawning threads by the `_thread` module. The following example demonstrates the use of this module. A thread is simply defined as a function that can receive any number of parameters. Below 3 threads are started, each one perform a print at a different interval.
|
|
|
|
```python
|
|
import _thread
|
|
import time
|
|
|
|
def th_func(delay, id):
|
|
while True:
|
|
time.sleep(delay)
|
|
print('Running thread %d' % id)
|
|
|
|
for i in range(3):
|
|
_thread.start_new_thread(th_func, (i + 1, i))
|
|
```
|
|
|
|
## Using Locks:
|
|
|
|
```python
|
|
import _thread
|
|
|
|
a_lock = _thread.allocate_lock()
|
|
|
|
with a_lock:
|
|
print("a_lock is locked while this executes")
|
|
```
