Function Documentation

◆ CAMERA_set_expecting_data()

uint8_t CAMERA_set_expecting_data ( uint8_t new_enabled )

Sets the UART interrupt state (enabled/disabled)

Parameters

new_enabled 1: command sent, expecting data; 0: not expecting data

Here is the caller graph for this function:

◆ GNSS_set_uart_interrupt_state()

void GNSS_set_uart_interrupt_state ( uint8_t new_enabled )

Sets the UART interrupt state (enabled/disabled)

Parameters

new_enabled 1: enable interrupt; 0: disable interrupt

Note: This function must be called very carefully. This type of GNSS is known to, in the wrong mode, spam null bytes, which can lock up the entire system. Thus, the interrupt is disabled by default, and must be enabled explicitly by the GNSS telecommands.

Here is the caller graph for this function:

◆ UART_init_uart_handlers()
