Functions
static TCMD_check_result_enum_t	check_for_and_handle_new_uart_tcmds ()
	Checks for an available telecommand in the UART buffer, and schedules it for execution.
void	TASK_handle_uart_telecommands (void *argument)
static TCMD_check_result_enum_t	check_for_and_handle_new_ax100_kiss_tcmd (uint8_t csp_packet_array[], uint16_t csp_packet_array_len)
	Checks for an available telecommand in the UART buffer, and schedules it for execution.
void	TASK_handle_ax100_kiss_telecommands (void *argument)

Variables
uint32_t	AX100_uptime_at_last_received_kiss_tcmd_ms = 0
	The system uptime, as of the last time a telecommand was received by the AX100 (and sent to OBC via KISS).
uint32_t	TCMD_handle_umbilical_tcmds_interval_ms = 400
	The interval between handling telecommands (parsing and adding to agenda) from the umbilical UART.
uint32_t	TCMD_handle_ax100_tcmds_interval_ms = 400
	The interval between handling telecommands (parsing and adding to agenda) uplinked via the UHF radio. Note: Does not include execution. Decrease this to 200ms-250ms (or lower) if bulk uplinking large amounts of data (e.g., firmware).

Function Documentation

check_for_and_handle_new_ax100_kiss_tcmd()

TCMD_check_result_enum_t check_for_and_handle_new_ax100_kiss_tcmd ( uint8_t csp_packet_array[], uint16_t csp_packet_array_len )

static

Checks for an available telecommand in the UART buffer, and schedules it for execution.

Returns

0 if no telecommand was available; 1 if a telecommand was found and executed.

Parameters

csp_packet_array	The CSP packet to read, starting with 4 bytes of CSP, and reading until null-termination after the CSP header.
csp_packet_array_len	The length of the csp_packet_array.

Variable Documentation

AX100_uptime_at_last_received_kiss_tcmd_ms

uint32_t AX100_uptime_at_last_received_kiss_tcmd_ms = 0

The system uptime, as of the last time a telecommand was received by the AX100 (and sent to OBC via KISS).

TCMD_handle_ax100_tcmds_interval_ms

uint32_t TCMD_handle_ax100_tcmds_interval_ms = 400

The interval between handling telecommands (parsing and adding to agenda) uplinked via the UHF radio. Note: Does not include execution. Decrease this to 200ms-250ms (or lower) if bulk uplinking large amounts of data (e.g., firmware).

TCMD_handle_umbilical_tcmds_interval_ms

uint32_t TCMD_handle_umbilical_tcmds_interval_ms = 400

The interval between handling telecommands (parsing and adding to agenda) from the umbilical UART.

Any value from 1ms to millions is reasonable. 20ms is a good value for optimized bulk uplink. Note: Does not include execution.
