can bus implementation with microcontroller

ADXL345 是一个小型的超低功耗，三轴加速度计，数字输出型，可通过SPI或IIC总线读取芯片数据，通过三个方向的加速度值可以计算出倾斜角度，具有中断输出和平衡位置偏移校准功能。(ADXL345 is a small, low power consumption, three-axis accelerometer, digital output type, can be read through the SPI or IIC bus chip data, through the three d

基于PN532NFC模块与STM32F10x的通信源码，可实现对NFC读写(Based on the communication source code between PN532NFC module and STM32F10x, it can read and write NFC.)
