Libs

• Test > this Lib tests the following peripheries of uPy VK boards:
  • I²C (expects slave to be connected on SDA & SCL )
    • Once Test.py & ssd1306.py are in FS of the board, you are ready to run it like so:

    >>> import Test
    >>> Test.OLED()

  • SPI (expects slave to be connected on SCK, MOSI, & D7-D9 )
    • Once Test.py & st7789.py are in FS of the board, you are ready to run it like so:

    >>> import Test
    >>> Test.TFT()

• Lvg > this Lib tests the LVGL module (expects SBC-LCD01 (SPI) or parallel (RGB) display to be connected):
  • Once pRGB.py, st77xx.py & lv_utils.py are in FS of the board, you are ready to run it like so:

  >>> import Lvg
  >>> Lvg.TST()

• MB > this Lib tests network module & RS485 of uPy VK boards:
  • Once gateway.py is in FS of the board, you are ready to run it like so:

  >>> import gateway
  >>> gateway.ON() # or use gateway.ON(True) if you want see the data, passing through the gateway.

  • Once started this gateway.py turns every uPy VK board in to a Modbus TCP/RTU Gateway device which can support one TCP master and multiple RTU slaves (RS485).
• MBserv > this Lib tests network module of uPy VK boards:
  • Once MBserv.py, umodbus folder & Settings.json are in FS of the board, you are ready to run it like so:

  >>> import MBserv
  >>> MBserv.UP() # or use MBserv.UP('<File_name>.json') if you want to start the server with non deffault settings (port and mac), you shuld put them in a json file.

  • Once started this MBserv.py turns every uPy VK board in to a Modbus TCP Server. All available LEDs can be set and read as coils and all available BTNs can be read as discret inputs. DACs & digital outputs D[0-13] can be set as holding registers. Digital inputs D[0-13] can be read as input registers. You can also control D[0-13] to be input or output from 1 of the holding regs.
• GWserv > this Lib tests network module of uPy VK boards:
  • Once GWserv.py, microdot folder content & Settings.json are in FS of the board, you are ready to run it like so:

  >>> import GWserv

  • Once started this GWserv.py turns every uPy VK board in to a WEB + Modbus TCP/RTU Gateway device. Gateway is configured through Settings.json file. WEB interface is under construction.
• CAMDisplay > this Lib tests LCD & CAM modules of uPy VK-RA6M3 board:
  • DEMO (expects OV7725 cam and paralel RGB display to be connected on M3 board)
    • Once started this DEMO captures the camera video and display it on the LCD screen. Touching the eye icon you can change between several camera effects.
• FlashDirList > this Lib tests network module of uPy VK-RA6M5 board:
  • DEMO (expects LAN cable to be plugged in M5 board)
    • Once started this DEMO starts web server and performs directory list function on the content of the internal flash of the board

Drv

• ssd1306 > murcopython OLED driver (works with devices based on that particular controller, such as SBC-OLED01)
• st7789 > micropython TFT driver (works with devices based on that particular controller, such as SBC-LCD01)
• st77xx > micropython TFT driver (LVGL)(works with devices based on SPI interface, such as SBC-LCD01)
• pRGB > micropython TFT driver (LVGL)(works with devices based on parallel interface, such as RGB)
