The wireless communication here is LoRa technology, using a LoRa communication module with a serial port interface . The main function configuration is as follows:
The serial port is initialized as:Se...
This circuit can automatically disconnect the charging or discharging circuit of two nickel-cadmium batteries when they are charged to 3V or discharged to 1.34V, effectively preventing overcharging or...
When I was referring to the design of an AVR (ATMEGA644PA-AU) chip, I found that the ISP download line uses the SPI port, which is the interface of PIN1, PIN2, and PIN3, while the JTAG interface in th...
[size=4]When COMS meets TTL, there is only confusion at this stage, because there is no rational understanding of the connection and difference between the two. For this reason, let's make a small com...
For combinational logic circuits, latches should be avoided. In the last test, I used a lookup table that displays octal numbers to pave the way for this test. This test is to test the latch detection...
