此程序为2.2寸串口TFT屏测试程序，驱动芯片为ILI9341，主控芯片为STM32F103_VCT6(This program is a 2.2 inch TFT screen serial testing procedures, driver chips for ILI9341, the master chip is STM32F103_VCT6)

这是ATmega128开发板的原理图和PCB文件，没有问题，用Protel 99直接就可以打开，已经打样测试过，很有参考价值。(This is the ATmega128 development board schematic and PCB files, no problem, using Protel 99 directly on the can open, have been tested proofing, great reference value.)

说明：  在CC2530上读取BH1750光照传感器数据并发送(This is a program that get Illumination data by BH1750 and send the data through CC2530.)
