Mega 2560 REV3 - 256KB (8KB after bootloader) Flash Memory 8KB SDRAM; 4KB EEPROM; 16MHz Clock Rate 8KB SDRAM 4KB EEPROM 16MHz Clock Rate The Arduino Mega 2560 is a microcontroller board based on the ATmega2560. It has 54 digital input/output pins (of which 15 can be used a...
If there is one thing Adafruit is known for, its mega-blinky-fun-rainbow-LEDs. We just love sticking NeoPixels anywhere and everywhere. When we saw the new 'PIO' peripheral on the RP2040 from Raspberry Pi, we just knew it would be perfect for driving large quantities of NeoPixels. So ...
EEPROM(Electrically Erasable Programmable Read-Only Memory)，叫做电可擦可编程可读寄存器。这是一种断电后数据不会丢失的存储设备，可以用来应对需要做记录做保存的场合。arduino已经为我们准备好了EEPROM类库”EEPROM.h”。https://www.arduino.cc/en/Reference/EEPROM 2 EEPROM库介绍 基于Arduino和Genuino AVR的主板...
// 1 = initial memory load failed // 2 = DMP configuration updates failed // (if it's going to break, usually the code will be 1) Serial.print(F("DMP Initialization failed (code ")); Serial.print(devStatus); Serial.println(F(")")); } // configure LED for output pinMode(LED_...
The ATmega 1284p shares pinout with the 644; the only difference is in memory size. We use the "Mighty 1284" platform as our model, because the needed files are mature and complete. Interrupt Pins: Mighty External Mighty Mighty Pin Interrupt Pin* PORT PCINT ATmega644/1284 pin Pin* PORT ...

MegaCore provides a standard, logical pinout for the 64-pin chips. The standard LED pin is assigned to digital pin 13/PIN_PB5. MegaCore includes the original Arduino Mega pinout for the ATmega640/1280/2560, but also a straightforward, "standard" pinout forall100-pin chips. The standard LED...
Considering the enhanced memory of the Mega2560, there really isn’t any reason to purchase a Mega. Figure 4-5. Baseline and extended board dimensions Figure 4-6 shows the overall dimensions of a Mega or Mega2560 board. Note that a baseline (Uno, Leonardo, etc.) shield will work with a...
