(Sort of) Running an Arduino Program Stored in Memory
Ever wonder if you could call a program stored as machine code inside of an array? It’s possible, however, there are some hurdles to overcome. First, the arduino (an ATMEL AVR based μC) is based upon the modified Harvard architecture. … Continue reading

Need More Memory? Arduino and 23LC1024
See this post for background information on interfacing the 23K256 SPI SRAM to the Arduino. Since the 23LC1024 is tolerant of 5V logic levels, it was much easier. However, note in the code below, the larger memory (1024K vs. 256K) … Continue reading
Microchip 23K256/Arduino Transfer Rates
I used my Saleae Logic to time the transfer (read/write) rates between the Arduino and Microchip 23k256 SPI SRAM. See this post for more information on the Arduino and 23K256. Here is the program that was running on the Arduino: … Continue reading
Interfacing Microchip 23K256 32KB SRAM SPI Memory with Arduino
My GPS Predictive Lap Timer Project needs more memory than the typical Arduino contains. However, it occurred to me that I could use a Microchip 23K256 32KB SRAM SPI memory chip and not need to revert to an Arduino Mega … Continue reading
