As shown in the figure, IN is +5V, which is used by the secondary side of the transformer to feed back to the power IC. Assuming that IN is greater than 5V, TL431 will be turned on, causing the K pole...
After installation (there is a red control in SYSTEM), put the SPCOMM control into the form, compile and pop up the SPCOMM unit file without writing a line of code. It fails to compile, as if a code u...
The INT0 interrupt of 51 has always been normal, but every time a function that generates a rectangular wave is called, the microcontroller does not enter the interrupt program even if there is an int...
I recently bought a few ATMEL memory chips from a merchant. I want 128K, but I always feel that it is not as big as the 32K I originally wanted. The chip I have now says: ATMEL316 24C256N SI27A. The b...
As for crystal oscillators, I have checked many manufacturers, and their worst accuracy is ≤50PPM, which means that there is only an error of 1 pulse in 20,000 pulses. For a 32.768kHz crystal oscillat...
