+ * Composite Keyboard and Mouse Example:
+ * This example uses PB12-PB15 and PA4-PA7 to simulate keyboard key pressing and mouse
+ * movement respectively, active low.
+ * At the same time, it also uses USART2(PA3) to receive the specified data sent from
+ * the host to simulate the pressing and releasing of the following specific keyboard
+ * keys. Data is sent in hexadecimal format and 1 byte at a time.
+ * 'W' -> 0x1A
+ * 'A' -> 0x04
+ * 'S' -> 0x16
+ * 'D' -> 0x07
