| + | Uses a handshake protocol (STB & ACK) to receive characters sent in 5-bit ASCII to it. | ||
| + | The characters are 'A' to 'Z' and repeat forever. All 26 characters of the alphabet are | ||
| + | sent. | ||
| + | |||
| + | Whenever a character is received, the bits 010 are appended to it to form an 8-bit ASCII. | ||
| + | |||
| + | When 'A' is recognized (hex 41), the receiver activates the on-board LED. When any other | ||
| + | character is received, the LED is turned off. | ||
| + | |||
| + | The program outputs each character to the serial monitor, which must be set to a baud rate | ||
| + | of 115200 baud. | ||
