stm32在抢占优先级和数码显方面的运用(the application of stm32f103vbt)

LPC23XX的自动升级代码,可以直接对HEX文件进行解析,然后烧到应用程序区.(lpc23xx series chip auto upgrade code, can directly parse the*.hex file from the filesystem,then burn it into the application area of the chip.)

通过无线模块接收GPS压缩数据，并进行校验和错误恢复，恢复算法采用位判别，三中取二。(GPS compressed data received through the wireless module and the checksum error recovery, the recovery algorithm uses a bit discriminant of three samples.)

1.传感器适用于土壤的湿度检测； 2.模块中蓝色的电位器是用于土壤湿度的阀值调节，顺时针调节，控制的湿度会越大，逆时针越小； 3.数字量输出D0可以与单片机直接相连，通过单片机来检测高低电平，由此来检测土壤湿度； 4小板模拟量输出AO可以和AD模块相连，通过AD转换，可以获得土壤湿度更精确的数值； 使用STM32驱动时，一般使用ADC读取其模拟量输出，以gokit stm32f103c8t6为例；">

说明：  ADI公司的AD4111是具有±10V和0 mA至20 mA输入和明线检测功能的低功耗 24 位 Σ-Δ ADC,集成了模拟前端(AFE),还集成主要模拟和数字的信号调理区快,为每个模拟输入通路配置成八种单独建立图,最大通路扫描速率6.2 kSPS(161 μs),嵌入的2.5V低漂移(5 ppm/℃)能隙基准电压降低了外接元件数量,单电源5V或3.3V工作,工作温度?40℃ 到 +105℃,主要用在过程控制PLC和DCS模块.本文介绍了AD4111主要特性,功能框图以及评估板EVAL-AD4111SDZ主要特性,框图,电路图,材料清单和PCB设计图.(The AD4111 is a low power, low noise, 24-bit, sigma-deltaanalog-to-digital converter (ADC) that integrates an analog front end (AFE) for fully differential or single-ended, high impedancebipolar,10 V voltage inputs, and 0 mA to 20 mA current inputs. The AD4111 also integrates key analog and digital signalconditioning blocks to configure eight individual setups for each analog input channel in use. The AD4111 features amaximum channel scan rate of 6.2 kSPS for fullysettled data.)
