[color=#000000]I made it with reference to Chunfeng's picture. Unfortunately, there is no hardware CC function. It can only be realized by software, which is slower than hardware. Next time I modify t...
Over the past decade, the dominant application for data converters has been in AC sampling and signal reconstruction. In very simple terms. A sampled data system is one in which the instantaneous valu...
The circuit form of using unidirectional thyristors instead of bidirectional thyristors is: two unidirectional thyristors are connected in reverse parallel, and the triggering requirements are: the pu...
One of my projects requires 8-way regulated power supply, 4V to 5V is fine, but it must be stable and not fluctuate too much, and each way has a load of about 5mA. I want to use a reference source chi...
Assume that data is read from 8-bit AD (if it is a higher-bit AD, the data type can be defined as int), the subroutine is get_ad();
