Board_info

Board_info: Mainly used for user-friendly development board pin configuration, built-in user-friendly naming and interface, which allows users to reduce the dependence on the electrical connection schematic.

1. Members

Board_info has many pin indexes and a list

1.1. pin_namelist

The list is mainly used internally by the class, and the user does not operate it.

1.2. Pin Index

The pin index is mainly to convert numbers into human-friendly strings, which is convenient for users to program.

Enter the following, please be careful not to ignore the . number, then press the tab key to complete, you can see the board-related pin functions.

board_info.WIFI_EN

2. method

2.1. Search method

When the user does not know the pin electrical connection, you can use this method to find

Board_info.pin_map(pin_num)

Parameters

This method does not pass in parameters or pass in a parameter

  • pin_num: pin number, range [6,47]

Board-level electrical connection information for all pins will be printed when no parameters are passed in

When the parameters are passed in, only the board-level electrical connection information for the specified pin is printed.

return value

  • Parameter error returns False
  • Unknown error return False
  • Find successful return information

3. Routine

3.1. Routine 1

Wifi_en_pin = board_info.WIFI_EN
Print(wifi_en_pin)# output is 8
Board_info.pin_map()# print all
Board_info.pin_map(8)# prints only pin 8 information
