Once upon a time, I had been thinking about how to realize some temperature, humidity, longitude and latitude data without sensors, until I thought of obtaining them from the weather forecast base sta...
SoPC is a special embedded microprocessor system. First, it is a system on chip ( SOC ) , that is, a single chip completes the main logic functions of the entire system; second, it is a programmable s...
Keeping pets is certainly a happy thing, but cleaning up their excrement may not be so happy. Many communities also have this problem. In Europe and the United States, people usually pick up the excre...
I used 430F149 to develop a small voice chip, and used the SPI serial port. Now I want to use the serial port debugging assistant to test the whole system, but I found that UART0 has been occupied by ...
Thanks for helping me! When I make a RS232 signal from outside and transfer it to 4 RS422, can the TXIN and RXOUT of MAX232 be directly connected to the RO and DI pins of four MAX491? If it is just on...
