Hi, so the gist of it will go like this.
You need to turn your for loop into a simple state machine that runs through the regular event loop. You'll want some kind of (global) counter to count the requests you processed. Let's call this "REQUEST_COUNTER".
When you click the button you need to launch the first capture, but you can't wait for it to return immediately:Then your "capture_done" will get the request and process it. Then, if it's not finished, it must launch the next capture request. Otherwise, it must finish all your processing. So probably like this:I haven't tried it but hopefully it's clear enough - maybe put a few print statements in there so that you can see what's happening. Good luck!

Code:
def on_button_clicked(): global REQUEST_COUNTER button.setEnabled(False) REQUEST_COUNTER = 0 picam2.capture_request(signal_function=qpicamera2.signal_done)Code:
def capture_done(job): global REQUEST_COUNTER request = picam2.wait(job) task = SaveDNGTask(picam2, i, request.get_metadata(), request.make_buffer('raw')) thread_pool.start(task) request.release() REQUEST_COUNTER += 1 if REQUEST_COUNTER < 10: picam2.capture_request(signal_function=qpicamera2.signal_done) else: thread_pool.waitForDone() button.setEnabled(True)Statistics: Posted by therealdavidp — Thu Apr 18, 2024 11:35 am
