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.
