The Lost Art of Cycle Counting
Let’s assume we want a 1/2 second delay inserted into our program (at least as close as we can get given crystal accuracy). We could simply rely on the built-in delay functions, or we could roll our own. So let’s … 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
