摘要：
1. General description
NXP Semiconductors designed the LPC2470 microcontroller, powered by the
ARM7TDMI-S core, to be a highly integrated microcontroller for a wide range of
applications that require advanced communications and high quality graphic displays. The
LPC2470 microcontroller is flashless. The LPC2470, with real-time debug interfaces that
include both JTAG and embedded trace, can execute both 32-bit ARM and 16-bit Thumb
instructions.
The LPC2470 microcontroller incorporates an LCD controller, a 10/100 Ethernet Media
Access Controller (MAC), a USB full-speed Device/Host/OTG Controller with 4 kB of
endpoint RAM, four UARTs, two Controller Area Network (CAN) channels, an SPI
interface, two Synchronous Serial Ports (SSP), three I
2
C interfaces, and an I
2
S interface.
Supporting this collection of serial communications interfaces are the following feature
components; an on-chip 4 MHz internal oscillator, 98 kB of total RAM consisting of 64 kB
of local SRAM, 16 kB SRAM for Ethernet, 16 kB SRAM for general purpose DMA, 2 kB of
battery powered SRAM, and an External Memory Controller (EMC). These features make
this device optimally suited for portable electronics and Point-of-Sale (POS) applications.
Complementing the many serial communication controllers, versatile clocking capabilities,
and memory features are various 32-bit timers, a 10-bit ADC, 10-bit DAC, two PWM units,
and up to 160 fast GPIO lines. The LPC2470 connects 64 of the GPIO pins to the
hardware based Vector Interrupt Controller (VIC) that means these external inputs can
generate edge-triggered interrupts. All of these features make the LPC2470 device
particularly suitable for industrial control and medical systems.
2. Features
? ARM7TDMI-S processor, running at up to 72 MHz.
? 98 kB on-chip SRAM includes:
? 64 kB of SRAM on the ARM local bus for high performance CPU access.
? 16 kB SRAM for Ethernet interface. Can also be used as general purpose SRAM.
? 16 kB SRAM for general purpose DMA use also accessible by the USB.
? 2 kB SRAM data storage powered from the RTC power domain.
? LCD controller, supporting both Super-Twisted Nematic (STN) and Thin-Film
Transistors (TFT) displays.
? Dedicated DMA controller.
? Selectable display resolution (up to 1024 × 768 pixels).
? Supports up to 24-bit true-color mode.
? Dual Advanced High-performance Bus (AHB) system allows simultaneous Ethernet
DMA, and USB DMA with no contention.

似乎发现了症结所在，火车头遇到特殊字符时会自动将特殊字符作为结束字符串，结果后面的内容就无法采集到了，本质上并不是字数限制问题
红红火火(541411572) 13:54:44
而是特殊字符的处理问题
红红火火(541411572) 13:55:44
特殊字符＝任何预先设置的结束字符串，火车头快帮忙解决哦

我遇到的特殊字符是   ?   ，火车头自动将这个作为结束字符串截取了，所有后面的内容当然采不到了
红红火火(541411572) 13:59:23
使用内容排除，不能解决问题
