I’m looking at using the Adafruit NeoTrellis RGB Driver PCB for 4x4 Keypad to replace the AW9534 I’m using for my sequencer project. Looking at the example codes, I’ve notice that there’s always a delay in the loop which is not something I want for my sequencer. Is there a way around it or is it mandatory?
Code: Select all
void loop() {
trellis.read();
delay(20);
}
