3 Discussion of measurement methods The applicable range of the built-in watchdog of ARM for time measurement is generally bounded by the μs order of magnitude. For example, from the device characteri...
I looked at the pins of 712 and it seems that there is no external interrupt pin, except P2.8 to P2.10 in 710. In addition to the capture in 712, are there other external interrupt pins?...
My study of electronics was actually quite bumpy. I used to study electromechanics, but there was no girl in the class, so it was boring. Later, I heard that there were many people studying electronic...
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();
