Functions
uint8_t	TCMDEXEC_uart_send_hex_get_response_hex (const char *args_str, char *response_output_buf, uint16_t response_output_buf_len)
	Send arbitrary commands to a UART peripheral, and receive the response.
uint8_t	TCMDEXEC_uart_get_last_rx_times_json (const char *args_str, char *response_output_buf, uint16_t response_output_buf_len)
	Get a JSON dict of how long, in ms, SINCE each UART ISR handler was last triggered.

Function Documentation

TCMDEXEC_uart_get_last_rx_times_json()

uint8_t TCMDEXEC_uart_get_last_rx_times_json	(	const char *	args_str,
		char *	response_output_buf,
		uint16_t	response_output_buf_len )

Get a JSON dict of how long, in ms, SINCE each UART ISR handler was last triggered.

Note

Uses placeholder "-99" to mean "never triggered". A value of 50 means that handler was last triggered 50ms ago.

Intended for debugging and testing purposes, but safe to use in flight also.

TCMDEXEC_uart_send_hex_get_response_hex()

uint8_t TCMDEXEC_uart_send_hex_get_response_hex	(	const char *	args_str,
		char *	response_output_buf,
		uint16_t	response_output_buf_len )

Send arbitrary commands to a UART peripheral, and receive the response.

Parameters

args_str	Arg 0: UART port name to send data to: MPI, GNSS, CAMERA, EPS (case insensitive) Arg 1: Data to be sent (bytes specified as hex - Max 5KiB buffer)
response_output_buf	The buffer to write the response to
response_output_buf_len	The maximum length of the response_output_buf (its size)

Returns

0: Success, 1: Error parsing args, 2: Invalid uart port requested, 3: Error transmitting data, 4: Error receiving data, 5: Timeout waiting for response / No response, 6: Peripheral specific error, 7: Unhandled error

Note

This function doesn't toggle the EPS power lines for peripherals. Ensure they are powered on before using this function.

The camera UART port does not support receiving data in the function. TX only.
