Is the Arduino Due a 32 bit microcontroller?
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. The Arduino Due is a microcontroller board based on the Atmel SAM3X8E ARM Cortex-M3 CPU.
Is it possible to receive a 9 bit protocol on the Arduino?
Is it possible to receive a 9 bit protocol on the Arduino Uno with Arduino? I want send and receive a 9 bit async-serial protocol with 4800 baud on my Arduino Uno, i have read on the specification from the ATmega328P that the uart can do that. My aim is that when my Uart receive the 9th bit as a 1 he must throw a interrupt.
Is the Arduino Uno compatible with the UART?
The good news is that the Arduino Uno’s UART supports 9-bit serial transmission. The bad news is that this support is not available in any standard library. Fortunately this forum post pointed to a modified version of the Arduino HardwareSerial code by Nick Gammon.
How many analog inputs does an Arduino Due have?
Adding two pullup resistor on SDA1 and SCL1 lines is required for using Wire1. The Due has 12 analog inputs, each of which can provide 12 bits of resolution (i.e. 4096 different values). By default, the resolution of the readings is set at 10 bits, for compatibility with other Arduino boards.
What does progmem do on an Arduino board?
There’s a description of the various types of memory available on an Arduino board. The PROGMEM keyword is a variable modifier, it should be used only with the datatypes defined in pgmspace.h. It tells the compiler “put this information into flash memory”, instead of into SRAM, where it would normally go.
What kind of port does the Arduino Due use?
The Native USB port is connected to the SAM3X. It allows for serial (CDC) communication over USB. This provides a serial connection to the Serial Monitor or other applications on your computer. It also enables the Due to emulate a USB mouse or keyboard to an attached computer.
What kind of current does a due Arduino have?
Each of the 54 digital pins on the Due can be used as an input or output, using pinMode (), digitalWrite (), and digitalRead () functions. They operate at 3.3 volts. Each pin can provide (source) a current of 3 mA or 15 mA, depending on the pin, or receive (sink) a current of 6 mA or 9 mA, depending on the pin.
