| cr1901_modern | tannewt: I'm not sure if this is the right channel, but since valentyusb is on topic... what do you mean by this feature specifically? https://github.com/hathach/tinyusb/issues/322 | 00:04 |

| tpb | Title: Callback from ISR? · Issue #322 · hathach/tinyusb · GitHub (at github.com) | 00:04 |
| tannewt | cr1901_modern: I'd like to have TinyUSB call a function in CircuitPython so I can set a flag to tell me that I need to run TinyUSB | 00:05 |
| tannewt | specifically tud_task | 00:05 |
| cr1901_modern | I didn't know there was a `dcd_isr` function in the API. And when an event is queued, aren't we already in the ISR? I forget whether tinyusb can queue its own events without direct intervention from the interrupt handler | 00:05 |
| tannewt | dcd_isr might just be the samd intermediate function | 00:06 |
| cr1901_modern | ahhh | 00:06 |
| tannewt | that's the only one I looked in | 00:06 |
| tannewt | I want tinyusb to to tell me "hey call tud_task soon" | 00:06 |
| cr1901_modern | Can the stack queue an event as its doing its own processing? As opposed to the isr calling dcd_event_* to post to the queue? | 00:07 |
| cr1901_modern | if so you might need to add that callback in a number of places (anyways wait for hathach to respond, I was just curious :P) | 00:07 |
| tannewt | ya, true | 00:07 |
| tannewt | I don't know exactly what I need. mainly I don't want to have to "poll" tud_task anymore | 00:08 |
| cr1901_modern | Well, tinyusb already integrates w/ a few RTOSes, which would be interrupt driven-only. | 00:09 |
| cr1901_modern | So I'm guessing there's a solution to what you want, but Idk it offhand :( | 00:09 |
| cr1901_modern | what's wrong w/ polling tud_task if there's no work to do? | 00:10 |
