"Precision" is used to describe the accuracy of physical quantities, which reflects the error between the measured value and the true value, while "resolution" is used to describe the scale division, ...
In the MSP430 microcontroller, one clock cycle = the inverse of the MCLK crystal oscillator. If the MCLK is 8MHz, then one clock cycle is 1/8us.
One machine cycle = one clock cycle, that is, each acti...
I believe everyone is familiar with the English name NB-IoT, but what exactly can it do? You may be a little confused. Today, let's give some examples of NB-IoT applications in real life.1. Applicatio...
It's the end of the year and it's time to rush through the project. I've been doing HW design verification and debugging intermittently for some time. I made the first version of the power supply main...
