# Test scripts
|
|
|
|
### **These are obsolete - please refer to [Python package](https://gitea.veleslabs.org/veles_labs/pyveles)**
|
|
|
|
~~Python scripts used for sensor reading, configuring and automated testing. All scripts assume that 485 converter device file is `/dev/rs485`.~~
|
|
|
|
## User scripts
|
|
|
|
Following scripts are meant to be used by user for sensor search, read and config (write).
|
|
|
|
### `find_device.py`
|
|
|
|
Search for device over all combinations of given baudrates and addresses. If no arguments are given, script tries all possible combinations (which takes really long time).
|
|
|
|
Usage:
|
|
|
|
```
|
|
./find_device.py [ -a [{FIRST_ADDR-LAST_ADDR | ADDR} ...] ] [ -b [BAUD ...]]
|
|
```
|
|
|
|
Examples:
|
|
|
|
```
|
|
Complete search (slow!):
|
|
./find_device.py
|
|
Look for devices 123,10,56 at baudrates 19200,115200:
|
|
./find_device.py -a 123 10 56 -b 19200 115200
|
|
Look for devices 10-55 at baudrate 19200:
|
|
./find_device.py -a 10-55 -b 19200
|
|
Look for device 1-10 and 55 at baudrate 115200:
|
|
./find_device.py -a 1-10 55 -b 115200
|
|
Look for device 1-10 at all possible baudrates:
|
|
./find_device.py -a 1-10 55
|
|
|
|
```
|
|
|
|
### `query_device.py`
|
|
|
|
Script for interaction with sensor. Allows reading from input register and read/write access to holding registers.
|
|
|
|
Usage:
|
|
|
|
```
|
|
./query_device.py ADDR [BAUDRATE] [{read [REGISTER ...] | write VALUE REGISTER}]
|
|
where:
|
|
- ADDR is Modbus address (use 0 for broadcast; note that only write can be broadcast)
|
|
- BAUDRATE is (optional) baud rate; default value is 19200
|
|
- action can be "read", "write" or can be omitted (defaults to "read all")
|
|
- REGISTER can be either human-friendly register name (e.g. "CO2") or register number (30001)
|
|
- read may have list of REGISTER arguments (combining both register numbers and names)
|
|
- VALUE is 16-bit integer in decimal format
|
|
- to get list of human-friendly names just read all registers from sensor (run script with address only)
|
|
```
|
|
|
|
Examples
|
|
|
|
```
|
|
Read all registers from sensor 247, default baud rate:
|
|
./query_device.py 247
|
|
Read only CO2 register from sensor 123, baudrate 4800:
|
|
./query_device.py 123 4800 read CO2
|
|
Read CO2, T_SHT4x and RH_SCD4x from sensor 222, default baudrate:
|
|
./query_device.py 222 read CO2 T_SHT4x RH_SCD4x
|
|
Turn LED off for sensor 247, baud 115200:
|
|
./query_device.py 247 115200 write 0 LED_on_register
|
|
Set brightness of all connected sensors to 50%:
|
|
./query_device.py 0 write 50 LED_brightness_register
|
|
```
