Two switches in one node
Posted: Tue Dec 14, 2021 11:44 pm
I'm new to ESP-IDF would like to know how to add two keys on a single node, if anyone can share the files it would be a great help.
If you want to create a single device with 2 controlled GPIOs, please refer to the GPIO Example
If you want to create 2 virtual switch devices in a single node, please refer to the Multi Device Example. The multi device example has 1 switch, 1 fan, 1 light and 1 temperature sensor on the same node. You can use similar logic to have 2 switches.
If you want help with configuring 2 buttons to control 2 switches, you can use the below snippet for reference, which is similar to what we have in the example here.
Code: Select all
button_handle_t btn_handle = iot_button_create(BUTTON_GPIO, BUTTON_ACTIVE_LEVEL);
if (btn_handle) {
/* Register a callback for a button tap (short press) event */
iot_button_set_evt_cb(btn_handle, BUTTON_CB_TAP, push_btn_cb, NULL);
}
