串口max30100工作原理

串口max30100工作原理

串口max30100工作原理
串口Max30100是一种集成了红外发光二极管、光电二极管和数
字信号处理器的模块,用于心率和血氧饱和度测量。

其工作原理如下:
1. 发光二极管发射红外光和可见光,Max30100模块中的发光
二极管会发射红外光和可见光到皮肤表面。

2. 光电二极管接收反射光,光电二极管接收到皮肤表面反射回
来的红外光和可见光。

3. 数字信号处理器处理光电二极管接收到的光信号,Max30100
模块中的数字信号处理器会对光电二极管接收到的光信号进行处理,提取出血液脉搏的信号。

4. 通过串口输出数据,处理后的血氧饱和度和心率数据通过串
口输出,可以通过串口连接到微处理器或者计算机进行进一步的处
理和分析。

总的来说,串口Max30100模块通过发射光并接收反射光,利用
数字信号处理器对光信号进行处理,最终通过串口输出血氧饱和度和心率数据。

这种工作原理使得Max30100模块在医疗监护、运动健康等领域有着广泛的应用。

电源供配采用MCI开发箱自带的恒压电源,数据显示采用由两片HC595动态驱动的8 个数码管。

考虑到对本项目作品的使用与数据采样处理,本人采用最高具有16 位精度的MAX30100芯片传感器作为主要的心率数据采集模块,MAX30100芯片内部集成ADC数据转换,以及多个可读写寄存器,本作品主要操作其中的FIFO寄存器进行数据采集。

同时MAX30100芯片传感器属于I2C 接口器件,故在程序开发中,采用I2C 接口协议进行。

General DescriptionThe MAX3000E/MAX3001E/MAX3002–MAX3012 8-channel level translators provide the level shifting nec-essary to allow data transfer in a multivoltage system.Externally applied voltages, V CC and V L , set the logic lev-els on either side of the device. Logic signals present on the V L side of the device appear as a higher voltage logic signal on the V CC side of the device, and vice-versa.The MAX3000E/MAX3001E/MAX3002/MAX3003 use an architecture specifically designed to be bidirectional without the use of a directional pin.The MAX3000E/MAX3001E/MAX3002/MAX3004–MAX3012feature an EN input that, when low, reduces the V CC and V L supply currents to < 2µA. The MAX3000E/MAX3001E also have ±15kV ESD protection on the I/O V CC side for greater protection in applications that route signals externally. The MAX3000E operates at a guaranteed data rate of 230kbps. The MAX3001E operates at a guaranteed data rate of 4Mbps. The MAX3002–MAX3012 operate at a guaranteed data rate of 20Mbps over the entire specified operating voltage range.The MAX3000E/MAX3001E/MAX3002–MAX3012 accept V L voltages from +1.2V to +5.5V and V CC voltages from +1.65V to +5.5V, making them ideal for data transfer between low-voltage ASICs/PLDs and higher voltage systems.

Propagation Delay from I/O V L to I/O V CC After ENFigure 4. Propagation Delay from I/O V CC to I/O V L After ENsourced to each load on the V L side, yet the device does not latch up.The maximum data rate also depends heavily on the load capacitance (see the Typical O perating Characteristics), output impedance of the driver, and the operational voltage range (see the Timing Characteristics table).Input Driver Requirements The MAX3001E/MAX3002–MAX3012 architecture is based on a one-shot accelerator output stage. See Figure5. Accelerator output stages are always in three-state except when there is a transition on any of the translators on the input side, either I/O V L or I/O V CC. When there is such a transition, the accelerator stages become active, charging (discharging) the capacitances at the I/Os. Due to its bidirectional nature, both stages become active during the one-shot pulse. This can lead to some current feeding into the external source that is driving the translator. However, this behavior helps to speed up the transition on the driven side.F or proper full-speed operation, the output current of a device that drives the inputs of the MAX3000E/ MAX3001E/MAX3002–MAX3012 should meet the fol-lowing requirements:•MAX3000E (230kbps):i > 1mA, R drv< 1kΩ•MAX3001E (4Mbps):i > 107x V x (C + 10pF)•MAX3002–MAX3012 (20Mbps):i > 108x V x (C + 10pF)where i is the driver output current, V is the logic-supply voltage (i.e., V L or V CC) and C is the parasitic capaci-tance of the signal line.Enable Output Mode (EN, EN A/B) The MAX3000E/MAX3001E/MAX3002 and the MAX3004–MAX3012 feature an EN input, and the MAX3003 has an EN A/B input. Pull EN low to set the MAX3000E/ MAX3001E/MAX3002/MAX3004–MAX3012s’ I/O V CC1 through I/O V CC8 in three-state output mode, while I/O V L1 through I/O V L8 have internal 6kΩpulldown resis-tors. Drive EN to logic-high (V L) for normal operation. The MAX3003 is intended for bus multiplexing or bus switch-ing applications. Drive EN A/B low to place channels 1B through 4B in active mode, while channels 1A through 4A are in three-state mode. Drive EN A/B to logic-high (V L) to enable channels 1A through 4A, while channels 1B through 4B remain in three-state mode.±15kV ESD Protection As with all Maxim devices, ESD-protection structures are incorporated on all pins to protect against electro-static discharges encountered during handling and assembly. The I/O V CC lines have extra protection against static discharge. Maxim’s engineers have developed state-of-the-art structures to protect these pins against ESD of ±15kV without damage. The ESD structures withstand high ESD in all states: normal operation, three-state output mode, and powered down. After an ESD event, Maxim’s E versions keep working without latchup, whereas competing products can latch and must be powered down to remove latchup.MAX3000E/MAX3001E/MAX3002–MAX301235Mbps, 8-Channel Level Translators Detailed Description The MAX3000E/MAX3001E/MAX3002–MAX3012 logic-level translators provide the level shifting necessary to allow data transfer in a multivoltage system. Externally applied voltages, V CC and V L, set the logic levels on either side of the device. Logic signals present on the V L side of the device appear as a higher voltage logic signal on the V CC side of the device, and vice-versa.The MAX3000E/MAX3001E/MAX3002/MAX3003 are bidirectional level translators allowing data translation in either direction (V L↔V CC) on any single data line.These devices use an architecture specifically designed to be bidirectional without the use of a direc-tion pin. The MAX3004–MAX3012 unidirectional level translators level shift data in one direction (V L →V CC or V CC→V L) on any single data line. The MAX3000E/MAX3001E/ MAX3002–MAX3012 accept V L from +1.2V to +5.5V. All devices have V CC ranging from +1.65V to +5.5V, making them ideal for data trans-fer between low-voltage ASICs/PLDs and higher volt-age systems.The MAX3000E/MAX3001E/MAX3002/MAX3004–MAX3012 feature an output enable mode that reduces V CC supply current to less than 2µA, and V L supply current to less than 2µA when in shutdown. The MAX3000E/MAX3001E have ±15kV ESD protection on the V CC side for greater protection in applications that route signals externally. The MAX3000E operates at a guaranteed data rate of 230kbps; the MAX3001E oper-ates at a guaranteed data rate of 4Mbps and the MAX3002–MAX3012 are guaranteed with a data rate of20Mbps of operation over the entire specified operating voltage range.Level Translation For proper operation, ensure that +1.65V ≤V CC≤+5.5V,+1.2V ≤V L≤+5.5V, and V L≤V CC. During power-up sequencing, V L≥V CC does not damage the device.During power-supply sequencing, when V CC is floating and V L is powering up, up to 10mA current can beM A X 3000E /M A X 3001E /M A X 3002–M A X 301235Mbps, 8-Channel Level Translators ESD protection can be tested in various ways. The I/O V CC lines of the MAX3000E/MAX3001E are char-acterized for protection to ±15kV using the Human Body Model.ESD Test ConditionsESD performance depends on a variety of conditions.Contact Maxim for a reliability report that documents test setup, test methodology, and test results.Human Body ModelFigure 7a shows the Human Body Model and Figure 7b shows the current waveform it generates when dis-charged into a low impedance. This model consists of a 100pF capacitor charged to the ESD voltage of inter-est, which is then discharged into the test device through a 1.5k Ωresistor.Machine ModelThe Machine Model for ESD tests all pins using a 200pF storage capacitor and zero discharge resis-tance. Its objective is to emulate the stress caused by contact that occurs with handling and assembly during manufacturing. Of course, all pins require this protec-tion during manufacturing, not just inputs and outputs.Therefore, after PCB assembly, the Machine Model is less relevant to I/O ports.Figure 5.

Typical I IN vs. V INApplications InformationPower-Supply Decoupling To reduce ripple and the chance of transmitting incor-rect data, bypass V L and V CC to ground with a 0.1µF capacitor. To ensure full ±15kV ESD protection, bypass V CC to ground with a 1µF capacitor. Place all capaci-tors as close to the power-supply inputs as possible.I2C Level Translation For I2C level translation for I2C applications, please refer to the MAX3372E–MAX3379E/MAX3390E–MAX3393E datasheet.Unidirectional vs. Bidirectional LevelTranslator The MAX3000E/MAX3001E/MAX3002/MAX3003 bidi-rectional translators can operate as a unidirectionaldevice to translate signals without inversion.
