Why is it said that parallel circuits have a shunting effect? What I don't understand is: after adding a new resistor in parallel to the original load resistor, the current of the original load resist...
I personally think this paragraph about CRC calculation method is easier to understand. I copied it from the book Computer Networks Fifth Edition P68-P80 for future reference. [img]http://blog.21ic.co...
How do threads in the same process communicate? Touch screen drivers and LCD drivers are both loaded by GWES. Can they be considered as multiple threads in the GWES process? Is thread communication in...
I am debugging ov9653 and I have encountered some problems. I cannot set the registers of ov9653 using IIC. I have used IIC to drive other chips and they are good. But when writing to ov9653, ov9653 n...
