Hello there, I was trying to get my DAC output which I set as a triangle wave from channel 1 and 2 on a "YOKOGAWA 2022" digital Oscilloscope. I had set the Pin 4 and 5 as AIN in GPIO Setup in the GPIO_InitStrcut and when I connected my pin4 and 5 to Oscilloscope, something happened and my programmer (which was a serial to usb device) isnt working anymore. Is it due to the thing that I kept my GPIO pins as AIN or something else ?
Thanks a lot dude for the info. Next time i'll take care of this as I just burnt my USB to serial converter which i was using for programming. :(
