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

Great Series of AVR Tutorials

If you are looking to move beyond playing simple LED games with your Arduino, I recommend starting with these tutorials on the ATMEL AVR chips. You will need to read/reference the datasheets for the chips also. Many of these tutorials … Continue reading

Simple Arduino Debugging Techniques

Here are a couple of simple techniques I have found useful for debugging: 1. Turn on/off the pin 13 LED by inserting a digitalWrite(13, HIGH) before/after questionable areas of your program. If the Arduino’s built-in LED turns on, then you … 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
