-====== UART ======
-===== API =====
-The part "signal_name" in the described functions will be replaced by the name of the signal. E.g. if your signal is called "debug_uart" then the API function "signal_name_send_bytes" will become "debug_uart_send_bytes".
-==== send ====
-<code>void signal_name_send_bytes(const uint8_t *data, const uint32_t length)</code>
-Will send "length" bytes from the buffer "data" out on the TX line of the UART.
-<code>void signal_name_send_String(char* str)</code>
-Will send out the bytes of the sting on the TX line of the UART.
-<code>void signal_name_putc(void* p, char c)</code>
-Will send out the byte "c" on the TX line of the UART. The pointer "p" will not be used. This function is provided to be compatible with printf().
-==== receive ====
-<code>uint32_t signal_name_get_num_received_bytes(void)</code>
-Returns the number of bytes that have been received on the RX line of the UART and have not been read.
-<code>uint8_t signal_name_get_next_received_byte(void)</code>
-Returns the next byte that has been received on the RX line of the UART.
-<code>bool signal_name_get_received_bytes(uint8_t *buf, const uint32_t length)</code>
-copies the "length" received bytes into the buffer "buf". If less than "length" bytes have been received then this function returns false.
