Functions | |
void | uart_init_circ_buf (tcirc_buf *cbuf) |
This will intialize the circular buffer head and tail of tcirc_buf struct. | |
void | uart_add_to_circ_buf (tcirc_buf *cbuf, uint8_t ch) |
This will add a new character to the circular buffer. | |
uint8_t | uart_get_from_circ_buf (tcirc_buf *cbuf) |
This will get a character from the buffer requested. | |
void | uart_clear_rx_buf (void) |
This will clear the RX buffer. | |
uint8_t | uart_circ_buf_has_char (tcirc_buf *cbuf) |
This will check for a character in the requested buffer. | |
uint8_t | uip_ntohex (uint8_t val) |
This will convert a nibble to a hex value. | |
void | itohex (uint8_t val, char *str) |
Convert integer to hex value. | |
uint8_t | uart_get_char_rx (void) |
This will wait for a new character from the ATmega1284p and timeout if no new character is received. | |
void | uart_init (void) |
Initialize UART to 38400 Baud Rate and only enable UART for transmission. | |
void | uart_deinit (void) |
Turn off UART for sleep mode. | |
void | uart_send_byte (uint8_t byte) |
Send one byte over the uart. | |
ISR (USART_RX_vect) | |
This is the USART RX complete interrupt. | |
void | uart_serial_send_frame (uint8_t cmd, uint8_t payload_length, uint8_t *payload) |
This function builds and sends a binary command frame to the ATmega1284p. | |
void | uart_timeout_msg (uint8_t x) |
This displays a time out message to the user based on the parameter reason x. | |
void | uart_serial_rcv_frame (uint8_t wait_for_ack) |
This will receive a frame from the ATmega1284p and parse the incoming data. | |
Variables | |
tcirc_buf | rxbuf |
The RX circular buffer, for storing characters from serial port. |
Handles the control of the USART for communication with the ATmega1284p for sending commands.
