Keystudio arduino ethernet mega pinout3/31/2024 ![]() Let’s install the driver of keyestudio V4.0 development board. When you tap ,a zip file of Arduino 1.8.12 version will be directly downloaded, and you only need to unzip it to finish installation. Select the version you want to download, the latest version could be downloaded.Īlternatively, you could select previous release.Ĭlick to download an installer of Arduino 1.8.12 version,which needs to be installed manually. When getting this control board, we need to install Arduino IDE Support TWI communication using the Wire library. The SPI pins are also broken out on the ICSP header, which is physically compatible with the Arduino Uno. These pins support SPI communication using theSPI library.External Interrupts: D2 (interrupt 0), D3 (interrupt 1).PWM Pins (Pulse-Width Modulation): D3 D5 D6 D9 D10 D11.Serial Communication: D0 (RX) and D1 (TX).Onboard has 6 analog inputs, labeled A0 to A5. You can supply an external power input DC7-12V through this pin to Arduino board. The function is the same as reset button.Ī 3.3 volt supply generated by the on-board regulator. A properly configured shield can read the IOREF pin voltage and select the appropriate power source or enable voltage translators on the outputs for working with the 5V or 3.3V.Ĭonnect an external button to reset the board. This pin on the board provides the voltage reference with which the microcontroller operates. This information can be checked at the top of IC. Before you load a new program on the Arduino IDE, you must know what IC is on your board. The main IC (integrated circuit) on the Arduino is slightly different from the panel pair. You can regard it as the brain of your board. To control the voltage provided to the Arduino board, as well as to stabilize the DC voltage used by the processor and other components.Ĭonvert an external input DC7-12V voltage into DC 5V, then switch DC 5V to the processor and other components.Īrduino board can be supplied with an external power DC7-12V from the DC power jack.Įach Arduino board has its own microcontroller. It tells us that the frequency is 16,000,000 Hertz or 16MHz. The number printed on the top of the Arduino crystal is 16.000H9H. How does Arduino calculate time? by using a crystal oscillator. When Arduino board communicates via serial port, receive the message, RX led flashes. Onboard you can find the label: RX(receive ) When Arduino board communicates via serial port, send the message, TX led flashes. Onboard you can find the label: TX (transmit) USB serial chip, translate the USB signal of computer into serial signal When the pin is HIGH value, the LED is on, when the pin is LOW, it's off.Īrduino board can be powered via USB connector.Īll you needed to do is connecting the USB port to PC using a USB cable. There is a built-in LED driven by digital pin 13. the value used as the top of the input range). Used with analogReference().Ĭonfigures the reference voltage used for analog input (i.e. Reference voltage (0-5V) for analog inputs. Using pinMode(), digitalWrite(), and digitalRead() functions. Or used as digital output pin to drive different modules like LED, relay, etc. Powering the Arduino, LED on means that your circuit board is correctly powered on.Īrduino MEGA has 14 digital input/output pins (of which 6 can be used as PWM outputs).These pins can be configured as digital input pin to read the logic value (0 or 1). When connecting to PC, program the firmware to ATMEGA328P-PU. In fact, slave the output devices to the SPI bus host. It is often called the SPI (serial peripheral interface) and can be considered an "extension" of the output. The AVR, an Arduino micro-program header consisting of MOSI, MISO, SCK, RESET, VCC, and GND. ICSP (In-Circuit Serial Programming) Header ![]() Flash Memory: 32 KB (ATMEGA328P-PU) of which 0.5 KB used by bootloader.PWM Digital I/O Pins:6 (D3 D5 D6 D9 D10 D11).We can plug in power by USB wire, DC head and Vin GND pins. The built-in ICSP port can burn the firmware for ATMEGA328P-PU directly. It has 14 digital input/output pins(of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, a USB connection, a power jack, 1 ICSP header, and a reset button. The processor core of Keyestudio V4.0 development board is ATMEGA328P-PU, fully compatible with ARDUINO UNO REV3. 6.3 How to Install the Driver of CP2102.
