I think there is something wrong with the installation of the meter in this circuit. It should be installed on the branch of resistor R4.
The meter is ready-made, and any current within 1MA can be rea...
This book is written by analog electronics master Li Lian (Fudan University). It is very thorough and explains in detail the design, principle and application of op amps. You will definitely regret it...
I am going to do a small project recently :), in which I am going to use BQ24196 for power management, to realize automatic control switching between external adapter and battery, and to realize autom...
I read the description of the Open1081 library and it seems much lighter with only a few functions. But it is not easy to use it. I have learned the Bluetooth library CC2541 before and it seems more c...
After the boot card is made, use the following steps to update or replace the system. Burn/update Android/ubuntu/Linux system 1. Select the SecureCRT software, select the number key "1", download the ...
I am using the Tm4c123GH6PM development board. When I use ccs7.0 to import the mpu9150 routine of TivaWare, an error occurs when I compile it. Why is this? There is no problem importing other routines...
This program is written to simulate the serial port hardware mechanism. When used, a timed interrupt can be set with a time interval of 1/4 baud rate. The receiving function is called once for ea...[Details]
