Introduction 1.1 Scope MFRD52x Mifare® Contactless Smart Card Reader Reference Design This document describes the functionality of the reference reader PCB based on the MFRC52x. It includes the functional and electrical specifications and gives the needed details to use this reader as a reference design. This reference reader implementation is based on the HVQFN32 package of the MFRC52x device. The MFRC52x it self is described in the corresponding data sheet: “Product Data Sheet - MFRC522 Contactless Reader IC”. “Product Data Sheet - MFRC523 Contactless Reader IC”. • • Antenna design and tuning is described in following application notes: • • “Application Note - Micore Reader IC family Directly Matched Antenna Design” “Application Note - 13.56 MHz RFID Proximity Antennas” 1.2 Features • Single 5 V up to 12 V unregulated external power supply • RS232 DSUB9 connector for easy connection to a host PC • Regulated voltage supply for all supply voltages • Variable Supply Voltage − TVDD = AVDD = DVDD: adjustable, 3.3V or 2.8 V − PVDD: adjustable, 1.8V or equal to DVDD − SVDD: adjustable, 1.8V, 2.8V or 3.3V • NRESET, IRQ signals externally accessible • Support of S2C interface • Analog test signal pins AUX1 and AUX2 • Digital test signal pins D6, D5, D4, D3, D2 and D1 depending on the interface • Breakable line between serial RS232 and MFRC52x section • Breakable line between serial MFRC52x and antenna matching section • Breakable line between antenna matching and antenna section • MFRC52x reader section can be connected via: − Serial UART − I2C − SPI • Antenna size: 33.5 mm x 51.0 mm Rev. 2.1 — 17.

Functional Description MFRD52x Mifare® Contactless Smart Card Reader Reference Design The MFRD52x reference reader PCB is a complete Mifare® reader reference design based on the MFRC52x. The reader PCB itself is divided in 4 parts: Table 1. PCB sections Measure Interface section Reader section Reason Enables the direct connection to an RS 232 interface via a DSUB9 socket connector. MFRD52x reader module. This module is the basic PCB including the MFRC52x Reader IC and all required components for a Mifare® reader plus the filter circuitry. Antenna matching section Matching circuit for single ended or complementary driver operation Antenna section Antenna coil PCB including the resistor RQ for quality factor adjustment. Three areas to break the PCB are foreseen for easy adaptation of the reference reader PCB: • Between the interface section and MFRC52x section • Between the MFRC52x section and the antenna matching section • Between the antenna matching section and the antenna section The default configuration uses pins and jumpers to connect the PCB sections. It is also possible to use 0 Ohm resistors instead of the pin and jumper connection. The MFRD52x reference reader PCB offers the possibility to be directly connected to microcontroller with serial UART, SPI or I2C interface. Note: In case of a direct connection to a microcontroller, the input and output voltage levels must be observed. For a detailed view of all different layers of the MFRD52x reference reader PCB, refer to Section “Schematic & Layout”. 3. PCB Marking Depending on the reader IC version and some external modifications, the PCB is labeled on the reader and antenna section 119321 Preliminary Data Sheet Rev. 2.1 — 17.

STM32F407简单视觉小板(识别二维码,数据矩阵码,apriltags,圆方形状检测)
本帖最后由 RCSN 于 2020-5-10 21:39 编辑     楼主前阵子帮别人开发了个简单低成本的二维码识别方案,使用STM32F407VET6+OV2640方案,成本估计不超过30,后来楼主觉得不够过瘾,在其192Kram的情况下,多加了二维码,数据矩阵码,apriltags,圆方形状检测等简单的识别,不过由于ram受限,识别的最高分辨率也只是240*160,还有90多k ram

射频同轴接头
作为一个射频工程师,测试人员,在日常的工作过程中,接触最多的除了测试仪表,校准件,连接线缆之外,就是各种不同设备之间的转接头了。我们在维修的过程中,发现有比较多的仪器的损坏,或者是测试指标不稳定,是由于转接头的损坏造成的,而且有些接头的连接固定的方式不对,每次修好的仪器,过去后客户又按照他们原来的方式去拧紧了。特别是在一些生产型的企业,由于操作人员流动性比较大,很多员工对于各种转接头都不一定认识,

随机函数:rand和srand的用法
首先我们要对rand&srand有个总体的看法:srand初始化随机种子,rand产生随机数,下面将详细说明。 rand(产生随机数) 表头文件: #include 定义函数 :int rand(void) 函数说明 : 因为rand的内部实现是用线性同余法做的,他不是真的随机数,只不过是因为其周期特别长,所以有一定的范围里可看成是随机的,rand()
