Hi ı am using MIMXRT1052 on custom board. I am using MCUXpresso as an ide with SDK_2.7.0_MIMXRT1052xxxxB. I tried to use GPIO2 pin 22 for interrupt. But ı cant get any interrupt. I examin examples of GPIO input and GPIO output.
When I modified the output sample for GPIO2 22nd pin, I measured the output with an oscilloscope. No matter how I make changes using the pin config tool, I get a maximum output of 1.16v. In the Input example, I can see the interrupt signal with the help of an oscilloscope (3V), but if I complete the connection between the signal and the processor, I see a signal at the mV level. Am ı skipping an adjustment ? Is that normal?
P.S. : I only change GPIO and pin definitions in two examples.
