This is a system that detects people and cars entering the premises of the house through the gate and notifies the people in the house. The place where the people of the house are is either the purlin, the greenhouse, or the workshop. Because they are far apart, they are connected wirelessly.
When it detects the movement of a person or car and determines that it is necessary to ring the chime, it notifies the other units. Also, when talking in the sensor range, it tries to avoid the chime ringing many times. API frame 2 is used for wireless XBee communication, the MPU is Renesas RX621, and the language is C/C++.
It will be helpful for those who are considering a similar system.
Of course, you can use it with other MPUs by replacing the part that operates the MPU registers.
For the MPU that connects to XBee serially, I was considering a simple MPU that I was using at the time, but the library did not have the function to handle raw serial data. That is, it cannot handle API frames. Therefore, I decided to use Renesas' RX621, which I used before and still has a development environment. Readers will probably use the MPU that they are good at, but it is possible if the part that operates the register of the MPU is replaced.
