Arduino Playground - Dataflash
rduino-NVM: Direct flash memory access, round robin virtual pages and EEPROM like memory. (Flash, VirtualPage, NVRAM) Arduino library to support external I2C EEPROMs. EZPROM: A library to help organize EEPROM access. A powerful key-value store for all data storage needs. MD_CirQueue: Library for FIFO queue implemented as a Ring Buffer.
Adding External I2C EEPROM to Arduino (24LC256)
Open-source electronic prototyping platform enabling users to create interactive electronic objects.
Memories of an Arduino - Adafruit Industries
Uses a surface-mounted ATmega1280 for additional I/O and memory. Arduino Mini: ATmega168 (Pro uses ATMega328) 8 MHz (3. 3 V model) or DAQduino is iCP12 usbStick that built in Arduino form of external ports connection. With these IO ports, user can easily plug in different type of 3rd party Arduino extension boards with direct connection to
External memory Flash SPI - element14 - Embedded
P. S: I seem to recall Uno did not have enough memory to perform External mode (although that might have changed in the recent releases (R2016b) because of better External mode capabilities). Mega has larger memory was able to do External mode.
Arduino MEGA 2560 32Kb RAM shield - Hackadayio
The Arduino Due can be powered via the USB connector or with an external power supply. The power source is selected automatically. Uploading sketches to the SAM3X is different than the AVR microcontrollers found in other Arduino boards because the flash memory needs to be erased before being re-programmed. Upload to the chip is managed by
Eeprom Page Write (Writing long strings to 24LC256)
2/26/2010This could easily live in your mega328's flash memory. If you want to change the animation occasionally, you could write to the flash. But it is probably easier to write to an external SPI chip. Either way, I see no great problem for the multiplexing to display each frame. So it depends on how efficient your Arduino code is.
duino - ATmega328 + SPI Flash Memory - Stack Overflow
Add 512K of external SRAM to Arduino Mega By admin September 7, 2011 September 5, Luckily mega128 comes with external memory interface that can be used to expand RAM to 64K without external means or even more with additional memory bank selection functionality.
How to optimize your Arduino memory usage - Liudr's Blog
Arduino Uno Arduino Uno R3 Front Arduino Uno R3 Back The input voltage to the Arduino board when it's using an external power source (as opposed to 5 volts from the USB connection or other regulated power source). You can supply Memory The ATmega328 has 32 …
