(1) Inductance is measured with a LCR meter 4284A* or equivalent.
Test frequency at 100kHz
(2) DC resistance is measured with a Digital Multimeter TR6871
(Advantest) or equivalent.
(3) Maximum allowable DC current is that which causes a 30%
inductance reduction from the initial value, or coil temperature to rise
by 40°C, whichever is smaller.
(Reference ambient temperature 20°C)

I can't figure out how to use ADS1.2 to debug interrupt programs.
When debugging with ADS, download the program to 0x3000 0000. If there is an interrupt vector at 0x00, the program debugging will succeed and enter the interrupt handler. Now the question is, how does...
