Discussed in #276
This code works with arduino-pico downgraded to 1.9.2, but fails with 1.9.3.
const uint POT_PIN = A0;
const uint SWITCH1_PIN = D14;
const uint SWITCH2_PIN = D15;
volatile int s1, s2, pot;
#define USE_INTERRUPTS 0
#if USE_INTERRUPTS
void switch1() {
s1 = digitalRead(SWITCH1_PIN) == LOW;
}
void switch2() {
s2 = digitalRead(SWITCH2_PIN) == LOW;
}
#endif
void setup() {
pinMode(SWITCH1_PIN, INPUT_PULLUP);
pinMode(SWITCH2_PIN, INPUT_PULLUP);
#if USE_INTERRUPTS
switch1();
attachInterrupt(digitalPinToInterrupt(SWITCH1_PIN), switch1, CHANGE);
switch2();
attachInterrupt(digitalPinToInterrupt(SWITCH2_PIN), switch2, CHANGE);
#endif
}
void loop() {
pot = analogRead(POT_PIN);
#if !USE_INTERRUPTS
s1 = digitalRead(SWITCH1_PIN) == LOW;
s2 = digitalRead(SWITCH2_PIN) == LOW;
#endif
sleep_ms(5);
}
void setup1() {
Serial.begin(115200);
}
void loop1() {
sleep_ms(500);
Serial.print(pot);
Serial.print(", ");
Serial.print(s1);
Serial.print("/");
Serial.println(s2);
}
I can get interrupts to work under 1.9.3 using gpio_set_irq_enabled_with_callback directly, but obviously that defeats the object of writing a hardware-independent sketch.
I had a quick look at the diffs from 1.9.2 to 1.9.3 but nothing leapt out at me. Then again I only wrote my first sketch two days ago, and it was more than two decades ago I last wrote any embedded software.
