+## StdIO.jack
+
+A library of functions for text based input and output over UART.
+
+***
+
+### Project
+
+* Implement `StdIO.jack`.
+
+* Run `StdIO_Test` in real hardware on iCE40HX1K-EVB using a terminal program connected to UART.
+
+* Compare your terminal output with:
+  
+  ```
+  StdIO test:
+  Please press the number '3': 
+  ok
+  readLine test:
+  (Verify echo and usage of 'backspace')
+  Please type 'JACK' and press enter: JACK
+  ok
+  readInt test:
+  (Verify echo and usage of 'backspace')
+  Please type '-32123' and press enter: -32123
+  ok

+## StdIO.jack
+A library of functions for textual input and output over UART.
+
+### 	function void printString(String s)
+Print the String s to UART_TX and disposes the String s.
+### function void printInt(int i)
+Prints the decimal representation of i to UART_TX
+### function void println()
+Prints the new line character to UART_TX
+### function int readInt(String message)
+Displays the message on the screen, disposes the message, reads from UART_RX the entered text until a newline character is detected, echoes the text to UART_TX, and returns its integer value (until the first non-digit character in the entered text is detected). Also handles user backspaces.
+### function String readLine(String message)
+Sends the message to UART_TX, reads from UART_RX the entered text until a newline character is detected, echoes the text to the UART_TX, and returns its value. Also handles user backspaces.
