【开源】开源一套使用者能自主控制并设计的迪文屏显示
1.背景介绍：
现有DWIN屏在细节上显示有些许不足：（1）在自动换行时无法单个单词截断 ；（2）无法自动判断是否有超宽显示； （3）无法多页显示；（4）无法脱离触摸功能等。现基于不够完善之处开源一套使用者能自主控制并设计的迪文屏显示框架供大家参考，后续有时间会基于这套框架开源更多的ui显示界面。
该框架优点：能够实现字符宽度计算、单词截断、自主控制换行、多页显示、多项菜单列表显示、动态菜单加载，文本超宽通过帮助信息显示未显示完全的字符、静态动态提示框多页显示且带指示条，并且可以无需触摸功能等。

3.以下是部分实现流程，具体请下载项目工程进行参考。

"The ARM? Cortex?-M4 processor is a high performance embedded processor with DSP \
instructions which allow efficient signal processing and complex algorithm execution. It brings \
an efficient, easy-to-use blend of control and signal processing capabilities to meet the digital \
signal control markets demand. The processor is highly configurable enabling a wide range \
of implementations from those requiring floating point operations, memory protection and \
powerful trace technology to cost sensitive devices requiring minimal area, while delivering \
outstanding computational performance and an advanced system response to interrupts.\n\
The advanced timer(TIMER0 & TIMER7) can be used as a three - phase PWM multiplexed \
on 6 channels.It has complementary PWM outputs with programmable dead - time generation. \
It can also be used as a complete general timer.The 4 independent channels can be used \
for input capture, output compare, PWM generation(edge - aligned or center - aligned counting \
modes) and single pulse mode output.If configured as a general 16 - bit timer, it has the same \
functions as the TIMERx timer.It can be synchronized with external signals or to interconnect \
with other general timers together which have the same architecture and features.\nIn deep-sleep mode, \
all clocks in the 1.2V domain are off, and all of the high speed \
crystal oscillator (IRC16M, HXTAL) and PLL are disabled. Only the contents of SRAM \
and registers are retained. Any interrupt or wakeup event from EXTI lines can wake up \
the system from the deep-sleep mode including the 16 external lines, the RTC alarm, \
RTC Tamper and TimeStamp event, the LVD output, ENET wakeup, RTC wakeup and \
USB wakeup. When exiting the deep-sleep mode, the IRC16M is selected as the system \
clock.\nThe Reset Control Unit (RCU) controls three kinds of reset: system reset resets the processor \
core and peripheral IP components. Power-on reset (POR) and power-down reset (PDR) are \
always active, and ensures proper operation starting from 2.4 V and down to 1.8V. The device \
remains in reset mode when VDD is below a specified threshold. The embedded low voltage \
detector (LVD) monitors the power supply, compares it to the voltage threshold and generates \
an interrupt as a warning message for leading the MCU into security."
