Chips LGT8F08/88/328 (AVR Compatible)

  • LGT8F328P - TQFP32 (LGT8F328D)
  • LGT8F328P - TQFP48
  • LGT8F328P - SSOP20

8F328 Board Features

  • 8F328P-U MCU used by the LGT8F328P, is a Atmel MEGA328P compatible chip.
  • 8F328D architecture design is relatively new, peripheral functions far stronger than Atmel MEGA328. Especially the program encryption ability is far more than MEGA328.
  • 8F328D can use 3V3 and 5V power supply running at 16M frequency, excellent level compatibility.
  • Built-in high-precision RC, no external crystal can be stable operation.
  • Less peripheral parts, circuit design is simple.
  • 12-bit ADC (analog-to-digital conversion)
  • On board DAC
  • Owned GUID (unique ID) can be used for chip program encryption
  • Built-in internal 1.024V / 2.048V / 4.096V ± 1% calibratable reference voltage source

  • All of our boards already had arduino bootloader
  • The board has no crystal, not need

Install Board

  • Install larduino HSP from here our github folder in the link below, to get support in arduino IDE, install guide refer to "Install.txt":
  • The current method:
Unzip Larduino_HSP_v3.6x.rar
Copy [sketches], [hardware] and [libraries] directories to arduino's sketchbook direcotry
Restart Arduino, you will see new board from [Tools]->[Border] menu.

Select use Pre-set Folder

LGT-board install.gif
  • Git clone our arduino project here - https://github.com/Edragon/Arduino.git
  • Point the arduino project folder to sub-folder LGT
  • You can find relevant examples, libraries and boards in setup
  • See GIF setup guide

Upload sketch

  • can use FTDI FT232 RL or PC2102 as usual arduino
  • Or Board LGT8F328P-LQFP-miniEVB
  • Choose board larduino-core w/LGT8F328D, the rest is the same as use arduino pro mini.
  • Detail guide please see here.

Current Known Issus

  • LGT8F328P use shared EEPROM from flash, normal EEPROM sketch config may not work
