I want to use a PIC16F877A as a slave device of the I2C interface. After writing the program and burning it, I found that the clock at the SCL end could not be input. After a period of time, when I in...
I want to stabilize the signal output by the low-frequency power amplifier without using a task chip. Can I use some simple components to stabilize the signal? Please give me some advice! Thank you in...
As shown in the figure below, the official 4-20mA schematic diagram is imitated. Since the microcontroller does not have DA, DAC7512 is used. During the debugging process, it is found that the 5V outp...
