Introduction

LPC1768 is based on LPC1700 series processor (Cortex-M3 kernel V2 version) small evaluation board, main frequency is up to 100MHZ. The evaluation board has Ethernet interface, USB HOST/Device interface, UART interface, SPI LCD interface, 16 bit LCD screen interface (optional). Mainly used in network equipment, automotive electronics, medical electronics, industrial control etc..

LPC1700 series chip is used for high performance ARM Cortex -M3 32 bit RISC kernel, the operating frequency is 100 MHz. It has a built-in high-speed memory (up to 512K bytes flash memory and 64K bytes SRAM), enhanced I/O port and connected to the two APB bus peripheral. The board contains 8 channel 12 bit ADC and 10 DAC, 4 general 16 bit timer, motor control PWM interface and much advanced communication interface: up to 3 pieces of I2C, SPI, 2 pieces of I2S, one SDIO, 4 pieces of USART, a USB Host/Device/OTG interface and 2 CAN Ethernet MIC interfaces, Quadrature Encoder interface
