使用cypress 蓝牙芯片，实现血压测量参考代码(This example project demonstrates the BLE Blood Pressure Sensor application workflow. The Blood Pressure Sensor application utilizes the BLE Blood Pressure profile to report blood pressure measurement records to the Client. Also the Blood Pressure Sensor application utilizes the Battery Service to notify the battery level and the Device Information Service to assert the Device Name, etc.)

跑马灯又叫走马灯、串马灯。由毛竹编织成马头，马尾，属于灯笼的一种。是传统特色手工艺品，亦是传统节日玩具之一。在过去，跑马灯一般在春节等喜庆的日子里才表演，由二十来位11—14岁小孩组成，边跳边唱，根据节奏快慢形成不同阵势，有喜庆、丁财两旺、五谷丰登的寓意。跑马灯属系在身上糊上颜色鲜艳的纸，如今已由丝绸取代(Entertaining diversions also called regimes, string of lantern. Woven from bamboo horsehead, horsetail, belongs to a kind of lanterns. Is a traditional arts and crafts, and it is one of the traditional holiday toys. In the past, entertaining diversions generally festive days before performance, such as the Spring Festival is composed of twenty to 11-14 years old children, dance while singing, according to different rhythm form appearance, have a festival, Ding Cai flourish, the meaning of good harvest. Entertaining diversions on the body belong to paste on the colored paper, is now replaced by the silk)

STM8s003+AT24C32+125Khz RF读卡程序(STM8 125Khz RF reader program)

用STM32做从机，PC机做主机的MODBUS多机通信实验。内附简单的使用说明(MODBUS slave EXP。PC use to master and MCU use to slave.)

51单片机12864液晶4位并行接口驱动程序(12864 4 51 MCU parallel interface driver)

说明：  用PHILIPS P89LPC915 完成的A/D 和 D/A转换的C源程序.(Philips P89LPC915 complete with A/D and D/A conversion of the C source.)

简易数字电压表 (no)

系统侧的电压在0.04秒到0.06秒发生15％的电压跌落，在0.06 秒到0.07秒分别加入了3次和2次谐波，幅值分别为基波电压的20％和15％，相位分别为负25度和35度。(System voltage side occurs in 0.04 seconds to 0.06 seconds 15 of the voltage drop in 0.06 seconds to 0.07 seconds and 3 were added to the second harmonic amplitude of 20 and 15 of the fundamental voltage, phase, respectively negative 25 degrees and 35 degrees.)

用STM32模拟IIC主机，读取24c0x的内容。(Using STM32 simulation IIC host, read the contents of the 24 c0x.)
