1 Overview
- attachInterrupt()
- detachInterrupt()
- noInterrupts() --- disable the interrupt
- Interrupts() --- enable the interrupt
We suggest you to use:
- D8 (GPIO4), D9 (GPIO5)
- D4 (GPIO13), D5 (GPIO12), D6 (GPIO14)
- D2 (GPIO2)
2 Examples
Use an encoder example:
- D8 connect to the channel A to receive the interrupt (rising)
- D9 connect to the channel B
#include "noduino.h" static int32_t pos = 0; static bool past_b = 0; void do_encoder_a() { past_b = (bool)digitalRead(D9); past_b ? pos++ : pos--; serial_printf("pos = %d\r\n", pos); } void setup() { serial_begin(115200); pinMode(D9, INPUT); attachInterrupt(D8, do_encoder_a, RISING); } void loop() { }
You can try the example in noduino-sdk/examples/noduino/encoder
