System¶

Enums¶

Power regulator modes.

DCDC is the default value. Note that LDO mode consumes more power.

Name	Description
`MIRA_SYS_POWER_DCDC`
`MIRA_SYS_POWER_LDO`

Possible reasons for a CPU reset.

Name	Description
`MIRA_SYS_STARTUP_REASON_POWER_ON`
`MIRA_SYS_STARTUP_REASON_RESET_PIN`
`MIRA_SYS_STARTUP_REASON_WATCHDOG`
`MIRA_SYS_STARTUP_REASON_SOFT`
`MIRA_SYS_STARTUP_REASON_UNSPECIFIED`
`MIRA_SYS_STARTUP_REASON_UNKNOWN`

Hardware specific system configuration.

Except for setting the power_regulator, this is obsolete. Use the mira_license.py tool to configure the frontend instead.

If both are used, the config from the license/certificate area is used.

This controls PA/front-end modes (combinations of bypass/active and rx/tx/idle, as well as antenna selection) and the power regulator.

Name	Type	Description
`frontend`	`const mira_net_frontend_config_t *`
`power_regulator`	`mira_sys_power_ctrl_t`	Set the power regulator type.

mira_status_t mira_sys_module_config_register(const uint32_t config_id, const mira_sys_module_config_t *config);

Register a configuration for a custom hardware module.

Gets an identifier to enable reference to said configuration.

Note

If used, must be called from mira_setup().

Name	Description
config_id	identifier for the config. This identifier must be flashed in the first uint32_t of sysconfig, for a module to load the corresponding registered configuration. Value must be within [0x4000..0x4003].
config	the configuration for a custom module.

Name	Description
MIRA_SUCCESS	The operation was successful.
MIRA_ERROR_INVALID_VALUE	The configuration is not valid: pointer is NULL, GPIO pins are not correct or the power regulator config is invalid.
MIRA_ERROR_INVALID_ID	The config_id is incorrect.

void mira_sys_reset(void);

Resets the node.

mira_sys_startup_reason_t mira_sys_get_startup_reason(void);

Get the reason for the latest CPU startup.

uint32_t mira_sys_get_pc_before_watchdog_reset(void);

Get the PC register before the latest watchdog reset.
