1. The variable 'digit' contains a value in range 0 to 9. Transmit this variable over UART based on the setup we did in the UART lab. 2. The variable 'digit' contains a value in range 10 to 15. Transmit this variable over UART in hex. For example, if digit=12, transmit C over UART. (A) uart_write_char(0 + digit); (B) uart_write_char('0' + digit); (C) uart_write_char('digit'); (D) uart_write_char(digit); (E) uart_write_char(digit-10+A); (F) uart_write_char(digit-10+'A'); (G) uart_write_char('digit'-10+A): (H) uart_write_char('digit'-10+ A')
