In the PIE interrupt process, before the interrupt request is sent to the CPU, it must first be determined whether PIEACKx is 0. If it is not 0, it continues to wait; if it is 0, it is set to 1 throug...
I'm begging for a very simple delay program, but when I actually simulate or run it, the program always jumps inexplicably. The picture is as follows. The gray part is where it actually runs. I don't ...
I use max9372 to convert a TTL signal into LVPECL signal. Why can't I test this LVPECL signal with an oscilloscope in the circuit? There is only a DC bias voltage, and the chip is fine, because if the...
