Write me ESP32 codes.

Create an arrangement of 4 slaves ESP32 controlled by one master ESP32 with wireless communication using LoRa protocol.

Each slave is connected to a sensor that generates a small positive or negative voltage. The master is connected to a trigger, when the trigger is activated the communication pipe will be open for 2 seconds and the master will read each one of the slaves in a specific order.

The Reading:

The slaves will be arranged on a straight line that goes slave 1, slave 2, slave 3, and slave 4.

When the master is triggered time will be 0s and he will read the measurement of the sensor if the slave 1, then he will read slave 2, then slave 3, and finally slave 4. Then the master will register a new time and read slave 1, slave 2, slave 3, and slave 4. This process of registering time and read each measurement will be repeated for 2 seconds, and the communication pipe will be closed until the master is triggered again.

In resume the code for the master ESP32 should do:

Trigger activates

Measurements start

Time = 0 ms -> measurement slave 1 -> measurement slave 2 -> measurement slave 3 -> measurement slave 4

Time = X ms -> measurement slave 1 -> measurement slave 2 -> measurement slave 3 -> measurement slave 4

.

.

.

.

Time = 2000 ms -> measurement slave 1 -> measurement slave 2 -> measurement slave 3 -> measurement slave 4

End

I can do it, but have some questions about details. 1) What is a range of the signals? And how precise it should be? 2) Negative signals cannot be readed directly by ESP. Is it possible to use opamps or other ways to c Lisää
