Library's Non-declared variables & too many arguments to function issues.

[QnBarb]

Version/revision of the library used

2.8.6

Describe the bug

Variables not declared: timerAlarmEnable; timerAlarmWrite; timerAlarmDisable(timer); gpio_intr_disable((gpio_num_t)params.recvpin); gpio_intr_enable((gpio_num_t)params.recvpin)

Too many arguments to function: timer = timerBegin(_timer_num, 80, true); timerAttachInterrupt(timer, &read_timeout, false)

To Reproduce

Compile/Upload

Example code used

#include <Arduino.h> #include <IRremoteESP8266.h> #include <IRrecv.h> #include <IRutils.h>

// an IR detector/demodulator is connected to GPIO pin 2 uint16_t RECV_PIN = 2;

IRrecv irrecv(RECV_PIN);

decode_results results;

void setup() { Serial.begin(115200); irrecv.enableIRIn(); // Start the receiver }

void dump(decode_results *results) { // Dumps out the decode_results structure. // Call this after IRrecv::decode() uint16_t count = results->rawlen; if (results->decode_type == UNKNOWN) { Serial.print("Unknown encoding: "); } else if (results->decode_type == NEC) { Serial.print("Decoded NEC: "); } else if (results->decode_type == SONY) { Serial.print("Decoded SONY: "); } else if (results->decode_type == RC5) { Serial.print("Decoded RC5: "); } else if (results->decode_type == RC5X) { Serial.print("Decoded RC5X: "); } else if (results->decode_type == RC6) { Serial.print("Decoded RC6: "); } else if (results->decode_type == RCMM) { Serial.print("Decoded RCMM: "); } else if (results->decode_type == PANASONIC) { Serial.print("Decoded PANASONIC - Address: "); Serial.print(results->address, HEX); Serial.print(" Value: "); } else if (results->decode_type == LG) { Serial.print("Decoded LG: "); } else if (results->decode_type == JVC) { Serial.print("Decoded JVC: "); } else if (results->decode_type == AIWA_RC_T501) { Serial.print("Decoded AIWA RC T501: "); } else if (results->decode_type == WHYNTER) { Serial.print("Decoded Whynter: "); } else if (results->decode_type == NIKAI) { Serial.print("Decoded Nikai: "); } serialPrintUint64(results->value, 16); Serial.print(" ("); Serial.print(results->bits, DEC); Serial.println(" bits)"); Serial.print("Raw ("); Serial.print(count, DEC); Serial.print("): {");

for (uint16_t i = 1; i < count; i++) { if (i % 100 == 0) yield(); // Preemptive yield every 100th entry to feed the WDT. if (i & 1) { Serial.print(results->rawbuf[i] * kRawTick, DEC); } else { Serial.print(", "); Serial.print((uint32_t) results->rawbuf[i] * kRawTick, DEC); } } Serial.println("};"); }

void loop() { if (irrecv.decode(&results)) { dump(&results); Serial.println("DEPRECATED: Please use IRrecvDumpV2.ino instead!"); irrecv.resume(); // Receive the next value } }

Expected behaviour

1. Compile.
2. Expect compile.

This seems to be related to C3 and features in the Arduino framework that has changed, see already existing issues.
