Interrupt not implemented for Python

[moris526]

Adafruits marks pin Nro 5 on Raspberry to use for interrupt (https://learn.adafruit.com/adafruit-neotrellis/circuitpython-code) but it is not used in the sample code. Nor can be use as it is

I bought 32 Noetrellis kits and really need that function

What are you trying to do?

What are you trying to do?

I am building a midi controller for synths. I bought one Neotrellis to try it out (im not a programmer) and worked fine with Arduino.
Then I bought 31 more boards. Then I realized I need more processing speed in the MCU since it is communicating with PC.
I bought Raspberry pi Zero. Now speed problem is solved but the Interrupt is not implemented for Rasp. And I really need it because it takes a long time to read the 32 boards and I need to check the serial port too .
First time I post here.

Any advice?

I'd recommend reading the interrupt pin with DigitalInOut before reading all of the neotrellis boards. That way you'll only read them all when something is pressed. I don't think you need interrupt support itself. You could also partition the boards so you only need to read a subset based on their isolated interrupt state.

Also, make sure your I2C bus is clocked as fast as it works reliably. Going from 100khz to 400khz will give you a bit of speedup.

Hi.
Form the Adafruit forum I m told I have to enable the interrupt. https://forums.adafruit.com/viewtopic.php?f=47&t=178190

Can you give me hand with that?

[tannewt]

Please be patient. Dave should get back to you on the forum.

[moris526]

OK. Thanks

Hey @moris526 I have a similar problem to yours. I've gone through all your posts on Adafruit, Arduino, etc. hehe

In the end, did you make any progress? I've managed to improve the latency. I would like to know how your project turned out.

Hey Man. I just had to modifi the project cause i could not fix it. I have a video on instagram moris.maybe Theres been a long time since im not using it. But we can talk if you want Sent from Outlook for iOS<https://aka.ms/o0ukef>
