Arduino mega adk timer pinout3/6/2024 ![]() So most likely I will want to implement a Phase Correct PWM Mode. Timer3, Timer4, Timer5: Timer 3,4,5 are only available on Arduino Mega boards. The Arduino has 3 timers and 6 PWM output pins. In the Arduino work the tone() function uses Timer2. Timer2: Timer2 is a 8bit timer like Timer0. The Arduino reference for attachInterrupt command gives this chart for interrupts and pins on the Mega board: BOARD INT.0 INT.1 INT.2 INT.3 INT.4 INT.5 Mega2560 2 3 21 20 19 18 However may pinout diagrams show: INT.0. If you want to give a closer look to this board we advice you to visit the official Arduino Mega ADK page in the Hardware Section. I want to set Megas timer 5 pins 45 and 46 to 25kHz to change the speed of some PWM fans (25kHz so its not so noisy). In the Arduino world the Servo library uses Timer1 on Arduino Uno (Timer5 on Arduino Mega). 1.0 pinout: added SDA and SCL pins for TWI communication placed near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board and the second one is a not connected pin, that is reserved for future purposes.įor information on using the board with the Android OS, see ( Google's ADK documentation). ![]() ATmega16U2 instead 8U2 as USB-to-Serial converter. The MEGA ADK has 16 analog inputs, each of which provide 10 bits of resolution (i.e.Plus it has an USB Host circuit that enable this board to communicate with USB Devices, and give them power supply.Īdditional features coming with the R3 version are: It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. Voir le graphique ci-dessous pour une (oserais-je dire) méga-carte des broches du Mega. It is compatible with Android's Accessory Development Kit examples. It has a USB host interface to connect with Android based phones. Well, I tried a longshot and used an Arduino Uno example, just swapping timer1 for timer4, and what do you know, it worked. The Arduino ADK R3 is a microcontroller board based on the ATmega2560 ( datasheet). I have an Arduino Mega ADK and would like to try interrupts using timer 4 or 5.
