# Connecting the Blocks

Assemble the project with the following configuration:

##### **uart\_rx Block**

- **Inputs:**
    - clk → system clock
    - uartRx → UART input pin
- **Outputs**: 
    - rxByte → connects to the logic block
    - byteReady → connects to both the logic block and uart\_tx

##### **uart\_logic\_const Block**

- **Inputs**: 
    - clk → system clock
    - rxByte → from rxByte output of uart\_rx
    - byteReady → from byteReady output of uart\_rx
    - compareChar → constant value (e.g., 8’h61 = 'a')
- **Output**: 
    - signal → connects to LED (led0)

##### **uart\_tx Block**

- **Inputs:**
    - clk → clock
    - reset → button (b0)
    - tx\_data → receives rxByte from uart\_rx
    - tx\_data\_valid → receives byteReady from uart\_rx
- **Output**: 
    - tx\_pin → connects to the UART TX output pin
    - tx\_data\_ready → not used in this simple project
