Does the LM1117 series have a negative voltage? I have a few questions: 1. Is the 1117 series an LDO? 2. Does the LM1117 series have a negative voltage? I don't know much about LDO. 3. I don't know mu...
Now we need to isolate and sample the 0-25V DC voltage with an accuracy requirement of 1%. Due to the price of the Hall voltage sensor
It’s quite high, I hope to change to other isolation sampling met...
CoreMark is needless to say, you can search it on Baidu. In short, it is just like AnTuTu, the higher the score, the higher the performance of the microcontroller.
Using the C/C++ development environm...
