The Butterfly's ATmega169 CPU is capable of speeds up to 8 MHz, however it is factory set by software to 2 MHz to preserve the button battery life. There are free replacement bootloaders available that will launch programs at 1, 2, 4 or 8 MHz speeds. Alternatively, this may be accomplished by changing the CPU prescaler in the application code.

Faustino is a physical computing platform geared towards process monitoring and control. The faustino platform consists of a single-board microcontroller with embedded analog and digital I/O support, an input module with LCD, sensors and actuators in form of solid state relays.
The basic scheme is to cycle through a repeating sequence of activities, at a set frequency (AKA time-triggered cyclic executive). For example, consider the example of an embedded system designed to monitor a temperature sensor and update an LCD display. The LCD may need to be written twenty times a second (i.e., every 50 ms).
Optional CIC61508 safety monitor. Arduino IDE supported via add-in, plus Eclipse-based tools with multicore debugger. MBZ Pro WiFi Atmega328P-PU MaxBlitz: MBZ Pro Mega is an Arduino compatible stand-alone board with a prototyping area and built-in Wi-Fi. Featuring a compact design, it helps to shrink Arduino projects and make it permanent.
Atmel ships proprietary (source code included but distribution restricted) example programs and a USB protocol stack with the device. LUFA [ 43 ] is a third-party free software ( MIT license ) USB protocol stack for the USBKey and other 8-bit USB AVRs.
Arduino (/ ɑː r ˈ d w iː n oʊ /) is an Italian open-source hardware and software company, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices.
Second, the LCD may initially be in one of three states: State 1: 8-bit mode; State 2: 4-bit mode, waiting for the first set of 4 bits; State 3: 4-bit mode, waiting for the second set of 4 bits; State 3 may occur, for example, if a prior control was aborted after sending only the first 4 bits of a command while the HD44780 was in 4-bit mode.
