• • Input: clk (System clock)

  • Outputs:

    • acc_mosi (sends commands to the accelerometer)

    • acc_sclk (SPI clock)

    • acc_cs (selects the accelerometer chip)

acc_controller Block

• • Input: acc_miso (receives data from the accelerometer)

  • Outputs: Processed data for conversion

twos_complement_to_ascii Block

• • Input: Processed data from the accelerometer

  • Output: Data converted to ASCII

uart_tx Block

• • Input: ASCII data

  • Output: uart_tx (transmits data via UART to a PC or other device)
