- print_table(register_address: int, register_count: int, labels: list, registers: list) -> None
- Print data in a table.
Print registers addresses, description and
current value in a colored table format.
Args:
register_address: First register number
register_count: Number of registers
labels: Registers description
registers: Registers values
Returns:
None
- request_info() -> str
- Request input data.
List all serial devices detected in use and wait for the user to choose
which port/serial device want to use.
Args:
None
Returns:
Return requested port name
- scan_system_config(port_name: str) -> None
- Detect system configuration for each possible MODBUS node.
Create an instrument object for each MODBUS node and read 5 analog
input registers with function code 4 starting from address 0.
Print registers description and value in a colored table.
Convert first 4 registers value in binary format and check if the least
significant bit is 0 or 1. If 0 is found, an analog input board have been
detected, else, if 1 is found, an analog output board have been detected.
Args:
port_name: COMPORT name
Returns:
None
- search_serial_port_id(device_description: str, view_device_description: bool = False) -> str
- Search for a serial device description.
Args:
device_description: Device description string
view_device_description: flag to display device description
Returns:
Device port name
- serial_devices() -> tuple
- Lists serial port names and description.
Search for all serial devices detected in use and return
their description and port name as a list with an index.
Args:
None
Returns:
Return a tuple of two lists, serial device(s) description(s)
and serial device(s) port(s).
- sleep(...)
- sleep(seconds)
Delay execution for a given number of seconds. The argument may be
