The PCA9555 is a 24-pin CMOS device that provides 16 bits of General Purpose parallelInput/Output (GPIO) expansion for I2C-bus/SMBus applications and was developed toenhance the NXP Semiconductors family of I2C-bus I/O expanders. The improvementsinclude higher drive capability, 5 V I/O tolerance, lower supply current, individual I/Oconfiguration, and smaller packaging. I/O expanders provide a simple solution whenadditional I/O is needed for ACPI power switches, sensors, push buttons, LEDs, fans, etc.The PCA9555 consists of two 8-bit Configuration (Input or Output selection); Input, Outputand Polarity Inversion (active HIGH or active LOW operation) registers. The systemmaster can enable the I/Os as either inputs or outputs by writing to the I/O configurationbits. The data for each Input or Output is kept in the corresponding Input or Outputregister. The polarity of the read register can be inverted with the Polarity Inversionregister. All registers can be read by the system master. Although pin-to-pin and I2C-busaddress compatible with the PCF8575, software changes are required due to theenhancements, and are discussed in Application Note AN469.

1.传感器采用的是Maxim的MAX30102（与MAX30101 pin-to-pin兼容，换用MAX30101应该有更好的心率测量效果）；2.单片机使用的是STM32F103；3.显示用的是OLED显示屏，显示心率、血氧饱和度还有两种波长光的波形。系统设计框图

The PW4055 is a complete constant-current /constant-voltage linear charger for single cell lithiumion batteries.Its ThinSOT package and low external component count make the PW4055 ideallysuited for portable applications.Furthermore, the PW4055 is specifically designed to work within USBpower specifications.The PW4055 No external sense resistor is needed, and no blocking diode is required due to theinternal MOSFET architecture.Thermal feedback regulates the charge current to limit the dietemperature during high power operation or high ambient temperature. The charge voltage is fixedat 4.2V, and the charge current can be programmed externally with a single resistor. The PW4055automatically terminates the charge cycle when the charge current drops to 1/10th the programmedvalue after the final float voltage is reached. When the input supply (wall adapter or USB supply) isremoved, the PW4055 automatically enters a low current state, dropping the battery drain currentto less than 2µA. The PW4055 can be put into shutdown mode, reducing the supply current to 25µA.The BAT pin has a 7KV ESD(HBM) capability. Other features include charge current monitor, undervoltage lockout, automatic recharge and a status pin to indicate charge termination and the presenceof an input voltage

Atmel芯片的LINUX菜鸟调试之路目标很明确：1.先直接下载官方的.Bin文件运行，看运行效果2.自己编译官方源码，得到.bin文件运行，看运行效果是否和官方的.bin文件一致。3.可以自行修改官方源码，得到自己设计板子的.bin文件并运行成功。其中bootstrap对于VXworks同样适用如果是自己做的板子，那么就直接从本文档的第二个阶段开始看即可。首先拥有一块Atmel的开发板，开发板一般可以向厂家申请（没有开发板也行，只要你有Atmel的任意一款，自己设计的也可以，可以运行操作系统的板子，例如9260，9200，9625，9G45，9X25等等都行，方法都一样），此处使用的是AT91SAM9X5-EK，开发板的主CPU是AT91SAM9X25。板子是Atmel官方提供的。要调试板子需要一些对应的软件环境。1CPU核心板可以贴SAM9G15，SAM9G25，SAM9G35，SAM9×25，SAM9X35等几个PlIN-TO-PIN的片子，他们的管脚PCB封装兼容2频率CPU为400MHZ，总线133MHZ3晶振时钟晶振12MHZ，32.768KHZ4RAM用的是1Gbit=1204/8=128MB的（DDR2）（miro 美光1.8V的MT47H64M16HR，16位的64M*16bit/8=128MB）5NAND用的是2Gbit=2048/8=256MB的FLASH（miro美光3.3V的MT29F2G08AAD，8位的）6Dataflash SPl的Dataflash是32Mbits=32/8=4MB的7EEPROM EEPROM是512Kbits是512/8=64KB的
