Arduino Pin Change Interrupts – The Wandering Engineer
The base frequency for pins 3, 9, 10, and 11 is 31250 Hz. The base frequency for pins 5 and 6 is 62500 Hz. The divisors available on pins 5, 6, 9 and 10 are: 1, 8, 64, 256, and 1024. The divisors available on pins 3 and 11 are: 1, 8, 32, 64, 128, 256, and 1024.
Fast digital I/O for Arduino - CodeProject
I have my Arduino board, on the pins 11, 10 and 9 are respectively connected the inputs R, G and B of all the LED (as on the diagram above). I Connected all PORTB pins in the input of pins of ULN2803. then the bases of the transistors to A0 (R), A1 (G), A2 (B). I used a very simple code. I just wanna light up all the leds so I feed up all

Embedded Electronics Blog Tutorials, Tips and Tricks on : AVR microcontroller, Embedded Electronics, Internet Of Things, and more ! We will learn how to use Atmel AVR’s GPIO ports and actually ‘code’ for writing/reading data to/from port pins in this AVR tutorial. It is slightly confusing for beginners, however once you understand it
A Brief Tutorial on Programming the ATMega (Arduino
Arudino reading the PORTB, PORTC, PORTD. 19 Jun 2012. The Arduino has a way to access the port registers (official documentation here), it allows lower-level and fast manipulation of the i/o pins on the micro-controller. This pertains to the ATmega8 and ATmega168. I did my testing with a …
How to Manipulate Arduino Pins Simultaneously - Teach Me
Arduino MEGA 2560 and Due. Both the MEGA 2560 and Due have 4 serial ports in total. One that connects through a USB port chip to the USB device port on the board and three extra serial ports that connect to pins on one of the pin headers of the board.
Arduino - PinMapping2560
Using the SWD pins SWDIO and SWCLK for general in / out . The SWD pins SWDIO and SWCLK are used for programming at the Arduino Zero or SAM 15x15. Also the program port communication to the SAMD21 of the Arduino Zero goes trough these pins.
Direct Control of Arduino Uno Digital Input/Output Pins
PORTB has Arduino pins 8 through 13 on it. Hint, if you want to know what PORTx register is associated with a Pin, look at the UNO Schematic… When the pin is configured for OUTPUT, digitalWrite() figures out with Port and Bit to change, and writes to it.
Arduino: Toggling Outputs - Bald Engineer
The Arduino Due is the first Arduino board based on a 32-bit ARM core microcontroller. With 54 digital input/output pins, 12 analog inputs, it is the perfect board for powerful larger scale Arduino projects.
