¶ Project Task
¶ Description
Device polls the door sensors one by one (supported from 1 to 5). Received data about the passengers getting on and of are recorded in telemetry.
Implemented the ability to send a command to reset counters in a particular sensor.
Additionally, diagnostic flags are monitored during program operation and user logs are recorded.
¶ Program Example
¶ Advanced
¶ Settings
MIN_POWER- minimum allowable supply voltage in millivolts.
Default is 10 000 mV.
DOORS_COUNT- number of connected sensors.
Default is 2.
Range from 1 to 5.
ID_1- ID of the sensor to be polled via the interface.
Default (forID_1) is 0001.
Range from 0000 to 9999.
ID_1- text parameter which must contain 4 characters. All characters are numbers from0to9.
For example, the identifier6should be given as0006
ID_2,ID_3,ID_4,ID_5- see the description ofID_1.
¶ User Parameters
User parameter CE No. 1 - passengers getting on from the sensor No. 1.
User parameter CE No. 2 - passengers getting off from the sensor No. 1.
- Parameter type: Unsigned integer number
- Recommended to transfer as 4 bytes parameter
- If the data is invalid: the value is "frozen"
User parameter CE No. 3 - passengers getting on from the sensor No. 2.
User parameter CE No. 4 - passengers getting off from the sensor No. 2.
User parameter CE No. 5 - passengers getting on from the sensor No. 3.
User parameter CE No. 6 - passengers getting off from the sensor No. 3.
User parameter CE No. 7 - passengers getting on from the sensor No. 4.
User parameter CE No. 8 - passengers getting off from the sensor No. 4.
User parameter CE No. 9 - passengers getting on from the sensor No. 5.
User parameter CE No. 10 - passengers getting off from the sensor No. 5.
User parameter CE No. 20 - diagnostic flags:
Bit 0 - polling of sensors is allowed (supply voltage is greater than MIN_POWER).
Bit 1 - there is incoming data on the interface (at least one message was received in the last 30 seconds).
Bit 2 - there are parsed messages (in the last 30 seconds, data was received from at least one message).
Bit 3..7 - reserve.
- Parameter type: Bitfield
- Recommended to transmit as 1 byte parameter.
User parameter CE No. 21 - sensor status flags:
Bit 0 - data from sensor 1.
Bit 1 - data from sensor 2.
Bit 2 - data from sensor 3.
Bit 3 - data from sensor 4.
Bit 4 - data from sensor 5.
Bit 5..7 - reserved.
- Parameter type: Bitfield
- Recommended to transmit as 1 byte parameter.

¶ Commands
¶ Reset counter for door X:
On command, device sends a message to the specified sensor to reset its counters.
¶ Command:
*!CEVT 1,door_num
door_num- sensor number from 1 to 5.
¶ Response:
*@CEVT
¶ Example:
Reset counter for sensor No. 3:
*!CEVT 1,3
