Data Structures | |
struct | tcirc_buf |
Circular buffer structure. More... | |
Defines | |
ASCII characters defined | |
#define | SOF_CHAR (0x01) |
Start-of-frame character. | |
#define | EOF_CHAR (0x04) |
End-of-frame character. | |
Functions | |
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. | |
uint8_t | uart_circ_buf_has_char (tcirc_buf *cbuf) |
This will check for a character in the requested buffer. | |
void | uart_clear_rx_buf (void) |
This will clear the RX buffer. | |
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_send_byte (uint8_t byte) |
Send one byte over the uart. | |
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_serial_rcv_frame (uint8_t wait_for_it) |
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. |
