Adding the Blocks

For this project, you will use three main blocks:

• uart_rx: Receives the byte sent via UART.
• uart_logic_const: Compares the received byte to the constant value.
• uart_tx: Sends data back to your serial console for verification or debugging
• LED block: Lights up depending on the implemented logic.

Now you have to connect the blocks:

a. uart_rx Block

1. Input:

• uartRx (receives UART data)

2. Outputs:

• rxByte (the received byte)
• byteReady (indicates when a byte is ready)

b. uart_logic_const Block

1. Inputs:

• rxByte (connect to rxByte from uart_rx)
• byteReady (connect to byteReady from uart_rx)
• compareChar (constant ASCII value set by the user, e.g. 97 for 'a')

2. Output:

• signal (goes high whenever the incoming byte matches compareChar)
  
  

c. LED Block

1. 1. Input:

      1. match (connect to the match output of uart_logic_const).

   2. Output:

      1. The LED lights up when the match is high.

d. uart_tx Block

1. Inputs:

• reset (Asynchronous reset, active high).
• tx_data (8-bit data to be transmitted).
• tx_data_valid (Indicates that the 8-bit tx_data is valid and ready to be sent).

2. Outputs:

• tx_data_ready (Goes high when the transmitter is idle or has completed sending data, signaling it can accept new tx_data).
• tx_pin (Serial data output line that connects to a UART receiver (PC or other device).
• For FPGA projects, the names of the input ports need to match those registered in the system to ensure the process runs correctly.
