I just started to learn how to use op amps. The project needs to amplify a small signal with a Vpp of 20mV (with a 1V DC bias) to 0~4V. I plan to use a bandpass filter to filter out high-frequency noi
Single-chip microcomputers can be programmed in assembly language, high-level languages C and Basic, or graphical languages. Programmable controllers are widely used in industrial control. The microco
As shown in the figure, this is a low-end current detection circuit, which mainly detects the current change from 1mA to 1A. At present, the performance of several 385s tested is different. Some 358s
The CPU of the MSP430 microcontroller belongs to a RISC (reduced instruction set) processor. The RISC processor is basically designed for high-level languages, because the reduced instruction system g
I have been engaged in the development of single-chip microcomputers for some years. Thanks to the continuous reduction in the cost of LCD, our products finally use color LCD. After a year of explorat
