The document discusses the capabilities of the Raspberry Pi compared to an Arduino. It summarizes that the Raspberry Pi has: 1) A 32-bit CPU running at 84MHz compared to the Arduino's 8-bit AVR CPU. 2) More memory resources including 96KB of SRAM and 512KB of flash. 3) Advanced peripherals including 53 GPIO pins, 5 UARTs, SPI, CAN and PWM interfaces well-suited for sensor reading, valve control, and analog output.
32bit Cortex Arduinoの布教とラパイド実験のススメ
- 4. 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.
- 5. 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 。
