 +====== MCU selection guide ======
  
 +A brief overview of MCU manufacturers and their products.
 +
 +===== Atmel =====
 +
 +  * 8-bit tinyAVR, megaAVR
 +  * 16-bit XMEGA
 +  * 32-bit AVR UC3, ARM
 +  * Most common among hobbyists
 +  * Programming tools are easily available
 +  * Well supported in Linux - [[http://​www.nongnu.org/​avr-libc/​|AVR libc]], [[http://​arduino.cc/​|Arduino]]
 +  * Dev boards: ​
 +    * [[http://​arduino.cc/​|Arduino]]
 +      * Arduino Duemilanove:​ USD30; The most common board ever! Features ATMega 168/328 (1k RAM, 512 EEPROM, 16k program flash) with 6x 10-bit A/D, 6x PWM, and bunch of other digital GPIO pins. User-friendly IDE. We have a couple of these, and some basic expertise ([[user:​pasky]]).
 +      * Arduino Mega: USD40; Very similar, but bigger memory and many more pins. [[user:​axtheb]].
 +      * Arduino Uno: ?; New iteration of Duemilanove,​ no experience yet **FIXME**
 +    * [[http://​www.atmel.com/​tools/​AVRBUTTERFLY.aspx|AVR Butterfly]]
 +    * [[project:​elbow:​start]]:​ Custom ARM board, [[user:​b00lean]].
 +  * Other resources: [[http://​www.avrfreaks.net/​|AVR Freaks]]
 +
 +
 +===== BeagleBoard =====
 +  * ARM Cortex
 +  * Expensive and with many features.
 +  * Already more like a stripped-down netbook w/o display.
 +  * **FIXME**
 +
 +
 +===== Freescale =====
 +
 +  * 8-bit S08
 +  * 16-bit S12
 +  * 32-bit Qorivva (Power arch), Kinetis (ARM), ColdFire
 +  * Widely used in industrial applications
 +  * Mostly expensive dev boards, although there are some exceptions
 +    * [[http://​www.element14.com/​community/​docs/​DOC-46626/​l/​element14-exclusive-freescale-kinetis-l-based-kl25z-freedom-development-board|Freedom KL25Z - Cheap Kinetis L-based board, pin compatible with Arduino]]
 +
 +
 +===== LeafLabs Maple =====
 +  * ARM Cortex, many pins...
 +  * USD50
 +  * **FIXME** no experience yet
 +
 +
 +===== Microchip =====
 +
 +**FIXME**
 +  * Dev boards:
 +    * ASIX PVK40 - Microchip PIC16Fxxx (84, 877, 887) - PIC16F887 - contains almost everything except ethernet and USB. [[user:​blackhead]] [[http://​blackhead.cz/​hackerspace/​equipment.html/​]]
 +
 +
 +===== NXP Semiconductors =====
 +
 +  * 32-bit ARM Cortex-M{0,​3,​4},​ ARM7 , ARM9
 +  * Good support in Linux
 +  * Dev boards: ​
 +    * [[http://​ics.nxp.com/​lpcxpresso/​|LPC Xpresso]]
 +    * [[http://​mbed.org|mbed]] - overpriced prototyping board based on NXP LPC1768 ARM Cortex M3 with an onboard ethernet controller and online IDE
 +
 +
 +===== Parallax =====
 +
 +  * Propeller architecture is suitable for tasks, where parallel processing is desirable (e.g. video generation)
 +  * Dev boards: [[http://​www.parallax.com/​Store/​Microcontrollers/​PropellerDevelopmentBoards/​tabid/​514/​CategoryID/​73/​List/​0/​SortField/​0/​catpageindex/​2/​Level/​a/​ProductID/​509/​Default.aspx| Propeller Proto Board USB]], [[http://​www.parallax.com/​Store/​Microcontrollers/​PropellerDevelopmentBoards/​tabid/​514/​CategoryID/​73/​List/​0/​SortField/​0/​catpageindex/​1/​Level/​a/​ProductID/​748/​Default.aspx|P8X32A QuickStart]]
 +  * Well supported in Linux - [[http://​hackaday.com/​2012/​06/​20/​parallax-shows-love-for-open-source-gcc-propeller/​]]
 +
 +
 +===== STMicroelectronics =====
 +
 +  * Cheap dev boards: [[http://​www.st.com/​internet/​evalboard/​product/​253215.jsp?​WT.ac=fp_may12_stm32f0discovery|STM32 Discovery]]
 +  * **FIXME**
 +
 +
 +===== Texas Instruments =====
 +
 +  * 16-bit MSP430
 +  * 32-bit Stellaris (ARM Cortex-M), Sitara (ARM Cortex-A), Hercules (ARM Cortex, safety critical applications)
 +  * Mediocre Linux support
 +  * Dev boards: ​
 +    * [[http://​e2e.ti.com/​group/​msp430launchpad/​w/​default.aspx|TI Launchpad]] ($4.30 including shipping)
 +      * low-power,​low-consumption,​low-cost uP
 +      * flash emulator on daughterboard [[http://​processors.wiki.ti.com/​index.php/​MSP430_LaunchPad_%28MSP-EXP430G2%29]]
 +      * Wiring library (Arduino code) support at [[https://​github.com/​energia/​Energia]] ([[user:​pasky]])
 +      * Linux support exists, but [[http://​log.or.cz/?​p=265|fragile serial communication]]
 +    * [[http://​www.ti.com/​tool/​ek-evalbot|Evalbot]]
