Chapter 0: Overview

Larduino HSP is the 3'rd party hardware support package for arduino compatible boards which based on LGT8F 8Bit RISC core, e.g LGT8FX8P series. Larduino_HSP is designed to make LGT8FX8P based arduino boards compatible with standard arduino software packages and IDE.

Here, we call arduino boards based on LGT8FX8P - "Larduino". Larduino boards implemented with LGT8FX8P/QFP32 are mostly compatible with Arduino Uno w/ ATMega328P. In most cases, LGT8FX8P can do everything as ATMega328p. But LGT8FX8P has many enhanced features which not included in ATMega328p and standard arduino implementation. So this is why Larduino_HSP comes.

First of all, We will outline the most difference between Larduino and standard Arduino Uno:

Features	Larduino w/ LGT8F328P	Arduino Uno w/ATMega328p
System Clock	up to 32MHz	up to 16MHz
Clock source	External crystal or Internal 32MHz RC	External 16MHz crystal
ADC	12bit x 8channel	10bit x 6channel
Timers	8bits x 2 16bits x2	8bits x 2 16bits x1
PWM channels	9 channels	4 channels
PWM Features	Complementary Mode Dead Band Insertion	-
Analog Comparator	Two	One
8bit DAC	One	-
Differential Amplifier	One (x8/16/32)	-
Hardware Accelerator	16bit ALU Hardware Multiply Add/Sub Hardware Divider	-
Maximum GPIO	x30	x20
Arduino Support	All	Parts
