单片机编程 STM32,5110液晶显示超声波测距探鱼器200KHz,带电路图,精确到厘米

STM32,5110液晶显示声纳探鱼器200KHz,带电路图,精确到厘米 MC34063升压,大声压发射,实际板子上滤波电路没要(电路图上的滤波电阻电容电感没焊,开路或者短路)。一般200KHz的换能器在水里面的耦合比较好,在空气中发射出来的(或者接收的)强度很低。 用的MOSFET Relay,contact和release时间都可以做到很小,不过选的 ...

嵌入式综合 linux内核分析

对于Intel x86 PC , 开启电源后, 机器就会开始执行ROM BIOS的一系列系统测试动作,包括检查RAM,keyboard,显示器,软硬磁盘等等。执行完bios 的系统测试之后,紧接着控制权会转移给ROM 中的启动程序(ROM bootstrap routine);这个程序会将磁盘上的第0轨第0 扇区(叫boot sector 或MBR ,系统的引导程序就放在此处)读入 ...

This firmware translates a PS/2 mouse to a USB mouse. The translator firmware is entirely interrupt driven (with the exception of sending the data via USB to the host.) An interrupt is generated when the PS/2 start bit is received, at which time the firmware will begin its receive routine. In ad ...

The module LSQ is for unconstrained linear least-squares fitting. It is based upon Applied Statistics algorithm AS 274 (see comments at the start of the module). A planar-rotation algorithm is used to update the QR- factorization. This makes it suitable for updating regressions as more data become a ...
