ARM7-based microcontrollers with Ethernet, USB, and CAN peripherals

基于STM32F407 实现USB UVC摄像头主机功能功能(Implementation of USB UVC camera host function based on STM32F407)

ARM对MMC卡的编程文档，通过它可以学习ARM对MMC卡的编程(ARM right MMC card programming documentation, which can learn from the MMC card ARM Programming)

用stm32测量血氧饱和度和心率。传感器为max30102。在oled上显示。效果较好(Blood oxygen saturation and heart rate were measured by stm32. The sensor is max30102. Display on oled. get a good effect.)

(1)个人针对atmel提供的运行于CPU内13k空间的ram的romboot修改而成。 (2)提供了IRQ和FIQ的测试工作； (3)提供了对外部sdram的数据总线和地址总线的测试工作 (3）提供了对spi dataflash和nor flash的访问操作 (4)实现了romboot在spi dataflash和nor flash中的升级 (5)因为受编译后文件不能超过13kbytes的限制，采用条件编译的方法控制各个功能((1) individuals provided for Atmel running on the CPU with 13k of ram space romboot modified form. (2) provides the IRQ and FIQ testing (3) provide for external SDRAM data bus and address bus of the test (3) provides a spi dataflash and visit nor flash operations (4) realize the romboot in spi dataflash and nor flash the upgrade (5) because of the compiled files should not exceed 13kbytes restrictions, conditions compiled using various functional control)

S3C44b0X 的中断程序代码................(Interruption S3C44b0X code ................)

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；">
