![]() ![]() The OCR5A value is used internally, so that when the count of externally applied pulses is 1000, it executes the ISR. Hello Im trying to use Arduino GIGA R1 WiFi to listen to I/O port writes of an 8080-based computer (Build 8080 Microprocessor kit). 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. 6x Analog INPUT pins (A0 to A5): By default, each pin can measure between 0V to 5V with 10-bit of resolution via a analog-to-digital converter (ADC). 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. The input voltage to the Arduino board when. I see that syntax in the original code, but it does not look correct. Instead, it features the Atmega8U2 programmed as a USB-to-serial converter. 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. OCR1A is connected to pin 11 of the Mega and OCR1B to pin 12. Note that timer1 can be used on a Mega but does not support all three output pins OCR1A, OCR1B & OCR1C. 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. 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. -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. Arduino Mega 2560 PIN mapping table A diagram showing the correspondence between the pins on an Arduino board and those of the ATmega2560 microcontroller. There are pin mappings to Atmega8 and Atmega 168/328 as well. 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). Below is the pin mapping for the Atmega2560. ![]()
