illumination sensor and send them to the host device by wireless communication.
Communication is possible with up to 4 slave devices for each host device.
(Communication is possible with up to a maximum of 15 devices by expanding the
system)
The host device sends the data received from the slave devices to a PC via UART.
② Remote Control Mode
The slave devices read the measurement value of the accelerometer at an interval of
200 milliseconds, and send the value to the host device by wireless communication.
Communication is between one slave device for each host device.
The host device sends the data received from the slave device to a PC via UART.

Operation From Startup to Demo Mode Selected
① When the power is turned on, the pressed status of demo switch 1 is detected.
② If demo switch 1 was not pressed, the device enters Sensor Logger Mode.
③ If demo switch 1 was pressed, the device enters Remote Control Mode.
The operation up to this point is common to the host device and slave device.
The above flow is shown in Figure 39.

Operation of Host Device in Sensor Logger Mode and Remote Control Mode
The host device has the same operation in both Sensor Logger Mode and Remote Control
Mode.
① Presses of demo switch 1 are detected.
② If a press of demo switch 1 is detected, the CPU operation mode changes.
The CPU operation mode is initially mode 1, and toggles between mode 1 and
mode 2.
③ A check is performed for whether there is a valid wireless reception from a slave
device.
④ If there is a valid wireless reception from a slave device, the received data is sent
to the PC via RS232C.
The above flow is shown in Figure 40.

7.2.4.3
Operation of Slave Devices in Sensor Logger Mode
① Presses of demo switch 1 are detected.
② If a press of demo switch 1 is detected, the CPU operation mode changes.
The CPU operation mode is initially mode 1, and changes cyclically as mode 1 ->
mode 2 -> mode 3 -> mode 1 …
③ A check is performed of whether it is the periodic time to get the sensor
measurement values.
④ If it is the periodic time to get the sensor measurement values, the measurement
values are got from the hygro-thermometer and illumination sensor, and the got
measurement values are sent by wireless. The program then waits for the sending
to finish.
⑤ Once the sending is complete, a check is performed for whether the standby
conditions are met. The standby condition is that the CPU operation mode is mode
3.
⑥ For the standby conditions, the CPU clock changes to the CR oscillator (4MHz).
⑦ A check is performed for whether the standby time has elapsed. The standby time
is the value of the sensor measurement value getting period minus the time taken
to get the measurement values from the sensors and the time to send by wireless.
⑧ Once the standby time has elapsed, the CPU clock is changed to the PLL oscillator
(80MHz).
The above flow is shown in Figure 41.

7.2.7
Application States
The nine states shown in “7.2.5 Application State Transitions” are described below.
① Reset state
This state is common to host devices and slave devices, and is the state immediately
after turning the power on and immediately after the reset switch is pressed.
The reset state performs software internal initialization processing.
The operating clock is the high-speed PLL (CPU: 80MHz/Peripheral: 40MHz).
② MAC library initial setting state
This state is common to host devices and slave devices, and is the MAC library initial
setting state after the software internal initialization processing is complete.
It performs initialization of the MAC library.
The operating clock is the high-speed PLL (CPU: 80MHz/Peripheral: 40MHz).
③ Demo mode decision state
This state is common to host devices and slave devices, and is the demo mode
decision state after the MAC library initial setting state.
It detects switch 1 pressed within a period of one second.
If switch 1 pressed is not detected within a period of one second, the demo mode is
set to Sensor Logger Mode, and if switch 1 pressed is detected, it is set to Remote
Control Mode.
The operating clock is the high-speed PLL (CPU: 80MHz/Peripheral: 40MHz).
④ Standby state
This state is common to host devices and slave devices, and is common to Sensor
Logger Mode and Remote Control Mode.
On the host device, it waits to receive wireless from the slave devices, and when it
receives valid data, it switches to the send data to PC state.
On slave devices, if it performs no processing for a fixed period of time, and when the
specified time elapses, it switches to the sensor measurement value read state.
The operating clock is the high-speed PLL (CPU: 80MHz/Peripheral: 40MHz or CPU:
60MHz/Peripheral: 30MHz).
65
AN706-00038-2v0-E
⑤ Send data to PC state
This is a host device state, and is common to Sensor Logger Mode and Remote
Control Mode.
It sends the data received by wireless from the slave devices to the PC via the UART.
Once the sending is complete, it switches to the standby state.
Data is still received from the slave devices while in the send to PC state, and if valid
data is received while in this state, it switches to the standby state and then performs
the processing.
The operating clock is the high-speed PLL (CPU: 80MHz/Peripheral: 40MHz or CPU:
60MHz/Peripheral: 30MHz).
⑥ Sensor measurement value read state
This is a slave device state which reads the measurement values from the sensors.
If the demo mode is Sensor Logger Mode, the measured data is read from the
hygro-thermometer, illumination sensor, and accelerometer, if the demo is mode is
Remote Control Mode, the data is read from the accelerometer.
Once reading the sensor measurement values has finished, it switches to the sensor
data wireless send state.
The operating clock is the high-speed PLL (CPU: 80MHz/Peripheral: 40MHz or CPU:
60MHz/Peripheral: 30MHz).
⑦ Sensor data wireless send state
This is a slave device state which sends the measurement values read from the
sensor by wireless communication.
Once the sending is finished, it switches to the prepare to sleep state.
The operating clock is the high-speed PLL (CPU: 80MHz/Peripheral: 40MHz or CPU:
60MHz/Peripheral: 30MHz).
⑧ Prepare to sleep state
This is a slave device state, and if the CPU operation mode is intermittent operation
mode, it stops the CPU clock, changes the peripheral clock to the 4MHz CR, and
switches to the sleep state. When not in intermittent operation mode, it switches to
the
standby
(high-speed
PLL CPU:
60MHz/Peripheral: 30MHz) state.
66
80MHz/Peripheral:
40MHz
or
CPU:
AN706-00038-2v0-E
⑨ Sleep state
This is a slave device state that performs nothing for a fixed period of time. It
operates with the CPU clock stopped and the peripheral clock set to 4MHz CR.
Once the specific period of time has elapsed, the clock changes to the high-speed
PLL (CPU: 80MHz/Peripheral: 40MHz), and it switches to the sensor measurement
value read state.
