Hi,Nordic Tech Support friends:
I try to use the pin "P0.10/NFC2" to ooutput a PWM wave,but only output zero.
The schematic is as follows:
The PWM signal should appear on both sides of R07,but not appear any PWM signal ,only zero.
I try to move away the MOS-FET "HL20N04",The problem still cannot be solved.
I have measured the connectivity between the chip and the resistor ,it's good.
I try to give a PULLUP signal to the resistor R07 from the MCU‘s pin “P0.10/NFC2” ,and about a 3V voltage appears on the both sides of R07.
To sum up, the pin “P0.10/NFC2” can give PULLUP signal,and can not give a PWM wave.
It was so strange,I am expecting your prompt reply.
Thanks!
