ARDUINO布教ラパイド実験のススメ

アルゴ検証をラパイドに。コンセプト検証に最終形は不要。イマジネーションを加速させるのは思考に追従する道具だ。

マイコンに３２ BITの POWERを

8BIT AVRとは違うのだよ• A 32-bit core, that allows operations on 4 bytes wide data

within a single CPU clock. (for more information go to int type page).

• CPU Clock at 84Mhz.

• 96 KBytes of SRAM.

• 512 KBytes of Flash memory for code.

• A DMA controller, that can relieve the CPU from doing memory intensive tasks.

• Hardware divide.

卓越したペリフェラル• GPIO 53ch　→バルブ叩き放題、センサ読み放題 ,　割り込み自在• 5 UARTs, 2 TWIs, 4 SPIs ,2 CANs　→拡張性無限大• 8bit PWM 11ch　→お手軽にアナログ吐きたい時に便利• 12bit DAC 12ch　→基準電圧さえ確保できれば立派な測定系に。• 12bit DAC 2ch　　→ヒーターや DCモータなどの制御に• Mouse / Keyboard →スタンドアロンヒューマンインターフェイスに。
