The Tiva-C (aka TM4C) LaunchPads〔(TI LaunchPad Product Description )〕 are inexpensive self-contained, single-board microcontrollers, about the size of a credit card or so, featuring an ARM Cortex-M4F 32-bit CPU operating at 80 to 120 MHz, manufactured by Texas Instruments.〔http://www.ti.com/lit/ml/spmt284/spmt284.pdf〕 The TM4C Series TM4C123G LaunchPad〔(EK-TM4C123GXL LaunchPad Evaluation Kit )〕 is an upgrade from TI's Stellaris LaunchPad adding support options for Motion Control PWMs and USB Host functionality. The more recently released TM4C1294 Connected LaunchPad〔(EK-TM4C1294XL Connected LaunchPad Evaluation Kit )〕 is the first cloud-connected offering in TI's LaunchPad ecosystem and provides a solid foundation for beginning and evaluating embedded IoT designs. There are many I/O pins (40 to 80 depending upon version) that have multi-personality, this means that they can be easily configured as digital inputs or outputs, analog inputs and outputs or other functions, allowing a great variety of applications, are just the multiple serial ports have the ability to interface with more items such as test cards or other communication modules, etc. Among those pins there are included the GND and POWER (3.3 V) pins. The clock is 80 or 120 MHz (vers based), which makes them 5 to over 7 times faster than the Arduino UNO's 16 MHz ATMEGA328P microcontroller. As with any Cortex M4, the CPU has some DSP (Digital signal Processor) instructions, with some limitations, one can do signal processing for example sampling human voice with a good quality, able to be processed in Matlab. The CPU contains the optional Floating-point unit with Single-Precision Floating Point operations supported. They have an additional USB port which can act as USB host, allowing the connection of multiple devices and the "Connected" one has an integrated 10/100 Ethernet MAC+PHY for internet connectivity. They also have a temperature sensor and on-board LED(s) and RGB LED(s), which allows you to generate various colors by combining the three basic colours (Red, Blue and Green) of the additive colour synthesis. The Tiva/TM4C LaunchPads come preloaded with software to demonstrate many of the capabilities of the ARM microcontroller and with a quickstart application to get up & running within minutes. ==Tiva LaunchPad== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Tiva-C LaunchPad」の詳細全文を読む スポンサード リンク
