![]() The OCR5A value is used internally, so that when the count of externally applied pulses is 1000, it executes the ISR. I see nowhere in the code which is using the timer out put pins A or B. Your first post correctly identified this problem. The code uses the timer in input capture mode which does not have an input pin broken out on the Mega. The value of OCF5B is no where determined, and it's not clear that it's value is setting the correct bit in TIMSK5. The Compare Interrupt need to be enabled. The code is using the compare A interrupt. I see that syntax in the original code, but it does not look correct. Timer3 has only been tested on the Mega"īut as well Timer3 (A) on Pin11 or (B) Pin12 did not work :-(.ĭoes anyone of you guys know how to handel it? Using one of the three calls that specify a pin, 1 will map to pin 11 on the Mega and 2 will map to pin 12. If you change it, millis (), delay (), and any libraries that depend on those functions will no longer work. ![]() OCR1A is connected to pin 11 of the Mega and OCR1B to pin 12. sheldor1: I haven't been able to find any examples related to the timer0 interrupt specifically in the Arduino mega 2560, That's because Timer0 is used to maintain the millis () clock. 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a. Note that timer1 can be used on a Mega but does not support all three output pins OCR1A, OCR1B & OCR1C. It has 54 digital input/output pins (of which 14 can be used as PWM outputs). ![]() Here is the original codeįor Excample I tried the follwing and several combinations of it: I already tried several combinations using timer 5 instance but was not successful. Project ist the metal detector found here. Arduino Mega 2560 offers a generous 8MHz bus width. It comes in a 32-pin ATSF (Arduino Tunable Flash) IC package and has a built-in clock with 65MHz clock speed. I found several Information that T5 (Pin47) can be used the same wise but I'm not able to get it run.ĭoes anyone of you know how to handel the code that T5 (Pin47) on Arduino Mega is controlled the same wise as T1 (Pin5) on Arduino Uno. Arduino Mega2560 is powered by an onboard AAA battery that can provide you with an output power of 1.2V. -Generate interrupt every 1000 oscillations of the search coilĭigitalWrite(12,HIGH) //-NULL SW. Unsigned char tflag=0 //-Measurement ready flag Problem is that Timer1 is not wird to Pin5 at Arduino Mega 2560. I'm having Problems to convert the following code from an Arduino Uno (ATmega168/328) into a running Version on the Arduino Mega 2560 (ATmega2560).
