Schematic PCB

Hardware circuit realizes SPI to Ethernet 10BASE-T

It introduces in detail how to build an SPI to 10BASE-T to realize network data sending and receiving. 10BASE-T uses two differential pairs: one for transmission and one for reception. Each pair is coupled through a transformer and the signals are differential and Manchester encoded. All schematics and diagrams are open.

Blood pressure monitor design based on MSP430F149

Based on the blood pressure monitor design of MSP430F149, the project file may not be opened. Please create the project by yourself and add several other *.c *.h files at a time according to the file names contained in the main file. There may be some problems with the final result, but the basic idea is correct. If you modify it a little, you should get the correct result.

Obstacle measuring car

A car with intelligent judgment function is designed and produced. The car has the following functions: automatic obstacle avoidance function; tracking function (driving according to the black track on the road); phototaxis function (finding the point light source in front and driving in place); It has the function of detecting the number of iron pieces placed on the road surface; it calculates and displays the distance traveled and the walking time, and can make sounds and light up. The work can be used as a high-end smart toy, or as a powerful application example for college students to learn embedded control.
