I have a SparkFun Simultaneous RFID Reader - M6E Nano that I interface with a SparkFun Serial Basic Breakout - CH340G (setup to use 5 volts logic) and everything works perfectly fine. If I leave ...

I believe that I've successfully programmed the Optiboot bootloader into the T841 board (using a USBtinyISP) given that the T841's LED flashes after burning the bootload, but when I try to upload my ...

It was an interface that launched a thousand hacks. Near trivial to program, enough I/O lines for useful work, and sufficiently fast for a multitude of applications: homebrew logic analyzers, chip ...

EFINIX社というFPGAメーカーがあるのだが、趣味用にちょいと使おうとしており、それに関した個人的なメモ。今回はFPGAの構成(Config)をSPI-Flashメモリに書き込む関連について脈絡なく。 FPGAへの書き込みというと、各社専用の書き込みケーブルのようなものが ...
