Note: Dual color temperature dimming is mainly achieved by changing the capacitance of C1 and C2, which results in different delays in VDD power-on time. Multiple capacitors are increased in sequence
Shouldn't the PN532's IRQ pin generate an interrupt when a card is received? I'm using the serial port mode, but why is it that even though I set the IRQ pin to be enabled, it doesn't work? I can read
