An Embedded system typically contains one off chip NOR Flash which is interfaced using an SPI peripheral. The boot code is stored in NOR flash device and it is executed by moving it to a RAM. This ...

First, we put the Bus Pirate into SPI mode at 30KHz and chose the default settings for all options. We enabled the Bus Pirate’s on-board 3.3volt power supply with a capital ‘W’. Data is ...

[Andy] stuffed some more RAM onto an Arduino Mega and his three-part walk through on the design, construction, and software is a great read and one of the more ‘hard core’ Arduino builds we ...

This makes the SPI perfect for systems, where performance is essential, or where the code can be moved from non-volatile memory to fast RAM, or for systems where device size and cost are the key, or ...
