Common zbus Channels
Infuse-IoT defines a number of common zbus channels to enable passing common
data between various software modules. These channels are defined with an
identifier (infuse_zbus_channel_id).
Accessing Common Channels
Infuse-IoT provides several convenience macros for accessing the common channels.
Before referencing a common channel, it must be declared using INFUSE_ZBUS_CHAN_DECLARE
together with a list of infuse_zbus_channel_id identifiers. Once declared, a pointer
to the channel can be obtained with INFUSE_ZBUS_CHAN_GET, and the type of the channel
is retrieved through INFUSE_ZBUS_TYPE.
Once a channel pointer has been obtained, all standard zbus APIs can be used.
INFUSE_ZBUS_CHAN_DECLARE(INFUSE_ZBUS_CHAN_BATTERY, INFUSE_ZBUS_CHAN_AMBIENT_ENV);
void print_system_battery(void)
{
INFUSE_ZBUS_TYPE(INFUSE_ZBUS_CHAN_BATTERY) battery;
zbus_chan_read(INFUSE_ZBUS_CHAN_GET(INFUSE_ZBUS_CHAN_BATTERY), &battery, K_FOREVER);
LOG_INF("Battery Voltage: %d mV Current: %d uA Charge: %d %%", battery.voltage_mv, battery.current_ua, battery.soc);
}
