用控制台程序倒着输出九九乘法表；输出结果按下图所示： 1*9=9 2*9=18 3*9=27 4*9=36 5*9=45 6*9=54 7*9=63 8*9=72 9*9=81 …… 1*3=3 2*3=6 3*3=9 1*2=2 2*2=4 1*1=1 ( 1*9=9 2*9=18 3*9=27 4*9=36 5*9=45 6*9=54 7*9=63 8*9=72 9*9=81 …… 1*3=3 2*3=6 3*3=9 1*2=2 2*2=4 1*1=1 )

这个例程主要实现的功能是无线温度测量，无线模块用的是NRF905，温度采集用的是TLC1543(The main functions of this routine is a wireless temperature measurement, the wireless module is NRF905, temperature acquisition using TLC1543)

说明：  主控cpu采用stm32f407vet6,采用口线模拟的spi总线来采集ads1118的俩路输入模拟信号。信号输入范围为0--2.048V。对应0--65535.(The main control cpu adopts stm32f407vet6, and adopts the spi bus of port line simulation to collect the two input analog signals of ads1118. The signal input range is 0--2.048V. Corresponds to 0--65535.)

Interactive interfaces are more and more integrated into many applications such as medical devices, process control, mobile phones and other hand-held devices. These interfaces are based mainly on graphic HMIs (human machine interface) using color LCDs. Worldwide, the desire for color support is growing dramatically. The purpose of this application note is to address this aspect by describing how to use the STM32F10xxx FSMC (flexible static memory controller) to drive a TFT color LCD. This document first describes how to connect a color LCD to the FSMC, then it provides a TFT LCD interfacing example. The demonstration firmware delivered with this application note, the STM32F10xxx firmware library, and other such firmware are available for download the STMicroelectronics website: www.st.com.
